The transition from internal combustion engine (ICE) industry to electric vehicle (EV) industry has significant financial implications for both the automotive industry, government, and associated partners. The shift to EVs could lead to savings in foreign exchange reserves, the creation of new jobs, and a reduction in greenhouse gas emissions. However, the transition could also result in job losses in the automobile and its associated manufacturing industry. This study aims to analyze the impact of this transition on different stakeholders in India. The study takes into account the different financial aspects that includes production, technology, government policy, skilling, employability, job creation, and other associated aspects on Indian economy. For the projected study different cases were considered with 2030 as the projected year with 30% EVs. A modest attempt is made to analyze the impact on associated partners. The findings of the study suggest that the transition to EVs could

The automotive industry is facing unprecedented pressure to reduce costs without compromising on quality and performance, particularly in the design and manufacturing. This paper provides a technical review of the multifaceted challenges involved in achieving cost efficiency while maintaining financial viability, functional integrity, and market competitiveness. Financial viability stands as a primary obstacle in cost reduction projects. The demand for innovative products needs to be balanced with the need for affordable materials while maintaining structural integrity. Suppliers’ cost structures, raw material fluctuations, and production volumes must be considered on the way to obtain optimal costs. Functional aspects lead to another layer of complexity, once changes in design or materials should not compromise safety, durability, or performance. Rigorous testing and simulation tools are indispensable to validate changes in the manufacturing process. Marketing considerations are also

The future of wireless technology - from charging devices to boosting communication signals - relies on the antennas that transmit electromagnetic waves becoming increasingly versatile, durable and easy to manufacture. Researchers at Drexel University and the University of British Columbia believe kirigami, the ancient Japanese art of cutting and folding paper to create intricate three-dimensional designs, could provide a model for manufacturing the next generation of antennas. Recently published in the journal Nature Communications, research from the Drexel-UBC team showed how kirigami - a variation of origami - can transform a single sheet of acetate coated with conductive MXene ink into a flexible 3D microwave antenna whose transmission frequency can be adjusted simply by pulling or squeezing to slightly shift its shape
North American automakers and EV battery firms have five years to erase China's dominance in technology and manufacturing or they may face the reality of buying batteries from China for the foreseeable future. That was the message from battery-analysis company Voltaiq CEO Tal Sholklapper at a media briefing in Detroit. “We're in the final innings now,” Sholklapper said. “If the industry around batteries and electric vehicles and all the follow-on applications wants to make it, we're going to have to change the way we play

ABSTRACT Department of Defense (DoD) systems are often highly complex, costly and have extraordinarily long life cycles. Due to these characteristics requirements that these systems will need to meet over their life cycle are highly uncertain. To meet future requirements more rapidly at a lower cost requires an understanding of how to manage uncertainty and architecture to make these complex systems more flexible, adaptable and affordable. This paper proposes an alternative approaches to traditional development through managing uncertainty and architecture in an iterative fashion with decision analysis methods. Several specific methods and tools are discussed to include: Influence Diagrams, Design of Experiments, Design Structure Matrix and Target-Oriented Utility. Collectively the approach identifies the component and architectural drivers of cost in military systems

ABSTRACT The objective in this paper is to understand the challenges of making additive manufacturing a future source of supply for the Department of Defense through the redesign of a part for metal laser Powder Bed Fusion. The scope of this paper involved the redesign of a single cast-and-machined part for an Army ground vehicle system. The component was redesigned using topology optimization based on suitable replacement materials and design data from the representative part. In parallel, a brief review of AM standards identified a process to qualify the component through post-processing, non-destructive evaluation, and witness testing. Alongside this redesign analysis, a brief cost analysis was conducted to understand the cost associated with manufacturing and qualifying this part for multiple AM materials. The resulting analysis demonstrated that for this component, which was subject to high design loads, Scalmalloy, Ti-6Al-4V, and 17-4PH Stainless Steel could produce the most cost

ABSTRACT In development of next generation products, 80% or more of the downstream costs associated are committed during design phase. If we could predict, with reasonable confidence, the long-term impact of design decisions, it would open opportunities to develop better designs that result in tremendous future cost savings, often with no compromise in key performance objectives. Systems engineering is, by its nature, multi-disciplinary. The aim of Integrated Product and Process Development is to bring these disciplines together in order to assess various downstream implications of early design decisions, creating better designs, avoiding dead-end designs that are costly in terms of design cycle-time, and realizing designs that are manufacturable while achieving the performance objectives. The goal is to build a downstream value analysis tool that links all the conceptual design activities. This capability allows a designer to realize the long-range impacts of key up-front design

ABSTRACT This paper will discuss how proven automotive systems engineering lightweighting principles and practices are being adapted and applied to combat and tactical ground vehicle systems. An automotive lightweighting methodology has most recently been utilized to reduce the weight of a light-duty pickup truck by 511 kilograms resulting in a 20.8% vehicle mass reduction. A holistic approach to light-weighting offers great benefits with additional mass reduction at a cost savings, reducing the overall vehicle lightweighting cost impact. Automotive studies have shown additional vehicle mass-reductions in the range of 3-5% are achievable when vehicles are aggressively light-weighted (i.e., approximate 20% vehicle mass reduction range). Although many factors like customer usage, function and performance requirements, production volumes, product life cycles, value stream, manufacturing infrastructure, litigation application, etc., are indeed considerably different between automotive and

ABSTRACT This work presents the development and application of an optimization algorithm for simultaneously improving the fatigue life and minimizing a representative manufacturing cost when assembling a ground combat vehicle. High stress in the occupied space of the weld decreases the fatigue life of the structure; therefore, by minimizing the weld’s exposure to high stresses, the structure’s life can be improved. The new capability for simultaneously improving the fatigue life of a welded structure while reducing a manufacturing cost is demonstrated by considering the welding of a representative panel of a v-hull. Selections are made for the weld placement, the weld type, and the type of filler material, in order to minimize exposure to high stresses and therefore maximize fatigue life. In addition to the stress evaluation, the optimization considers manufacturing cost as another objective in parallel. The final evaluation provides an assembly design to increase the fatigue life and

ABSTRACT Flash® Bainite Processing employs rapid thermal cycling (<10s) to strengthen commercial off the shelf (COTS) steel sheet, plate, and tubing into Ultra Hard 600 Armor, High Hard 500 Armor, and advanced high strength steel (AHSS). In a continuous process, induction technology heats a narrow segment of the steel cross section in just seconds to atypically high temperature (1000-1300°C). Quenching substantially immediately follows. A report by Benet Labs and Picatinny Arsenal, investigating a less mature flash technology in 2011, surmised that the novel flash bainite process for steels has the potential to reduce cost and weight while also enhancing mechanical performance [1]. Receiving five financial grants, the US Dept of Energy has greatly matured flash technology in the last few years and its metallurgical understanding in collaboration with Oak Ridge National Lab and others. DOE has named Flash Bainite as the “SBIR Small Business of the Year” in May 2018 and awarded a Phase 3

ABSTRACT The OMU (orientation measurement unit), a combination of inertial (accelerometer, gyroscope), magnetometer and GPS/GNSS sensors, can play a significant role in the stabilization, orientation, navigation and munitions guidance applications performed in ground-based military vehicles. The raw data measured by the OMU’s sensor array includes angular rate, acceleration, magnetic field strength as well as position. By blending these sensor measurements with the use of software algorithms (a.k.a. sensor fusion), the data can be transformed into orientation data (pitch, roll & yaw), commonly referred to as Euler Angles. OMUs have a wide range of price that depends on the quality of its individual device sensors, environmental packaging, standards met and the sophistication of the device firmware used to filter, correct and smooth the inertial inputs used in the computation of application output data. In the ground-based military vehicle industry, applications supported by the OMU

ABSTRACT The Product Director for Contingency Base Infrastructure (PD CBI) is chartered to bring a system-of-systems approach to contingency basing. PD CBI has four major lines of effort to accomplish the mission. This paper briefly touches on the Strategic Recommendations, Analytical Support, and Stakeholder Collaboration and Integration lines of effort and focuses on the Contingency Basing Interface to the Warfighter line of effort. The paper outlines the Model-Based Systems Engineering (MBSE) approach employed by the CBI team, detailing the application of a common set of tools to address each part of the problem. The paper also addresses the use of existing models and simulations, modifying them for use with base infrastructure materiel, and developing new tools as needed, to conduct analyses treating a contingency base as a system of systems (similar to a ground vehicle system). The results of the analyses will provide the Army with materiel investment recommendations for decision

ABSTRACT It is time for Affordability and Producibility (AP) to take a more dominant role in Systems Engineering (SE). Functional design is no longer good enough. Cost, complexity and readiness must be drivers for optimum integrated design. Without focusing more on AP, we will continuously fuel the “design, respin, re-spin again” problem that drives significant cost and time into a system where the pace for delivery to theatre is moving as fast as ever. This paper describes the SE approach from an AP focus. Decisions and challenges that were encountered during the DRS OBVP design will be presented as a “real world” example. This paper will present the high level considerations to put AP up front in SE to drive decisions so that safe, reliable, cost effective products are delivered to the Warfighter in this tough, fast paced military environment

ABSTRACT Use of Model-Based Design (MBD) processes for embedded controls software Development has been purported for nearly the last decade to result in cost, quality, and delivery improvements. Initially the business case for MBD was rather vague and qualitative in nature, but more data is now becoming available to support the premise for this development methodology. Many times the implementation of MBD in an organization is bundled with other software process improvements such as CMMI or industry safety standards compliance, so trying to unbundle the contributions from MBD has been problematic. This paper addresses the dominant factors for MBD cost savings and the business benefits that have been realized by companies in various industries engaged in MBD development. It also summarizes some key management best practices and success factors that have helped organizations achieve success in MBD deployment

ABSTRACT An important aspect of any new ground vehicle acquisition program is an analytic understanding of the key performance, cost, risk and growth tradeoffs inherent with the system design. The Whole System Trades Analysis Tool (WSTAT) provides a holistic framework for modeling and understanding these tradeoffs. In this paper, we present the overarching WSTAT methodology and then consider a specific implementation for the Army’s Squad Multipurpose Equipment Transport (SMET) autonomous ground vehicle. Emerging results regarding high-level SMET design considerations are provided to demonstrate the types of decision support enabled by the WSTAT capability

Abstract On the Mobile Detection Assessment Response System (MDARS) production program, General Dynamics Robotics Systems (GDRS) and International Logistics Systems (ILS), are working with the US Army’s Product Manager – Force Protection Systems (PM-FPS) to reduce system costs throughout the production lifecycle. Under this process, GDRS works through an Engineering Change Proposal (ECP) process to improve the reliability and maintainability of subsystem designs with the goal of making the entire system more producible at a lower cost. In addition, GDRS recommends substitutions of Government requirements that are cost drivers with those that reduce cost impact but do not result in reduced capability for the end user. This paper describes the production lifecycle process for the MDARS system and recommends future considerations for fielding of complex autonomous robotic systems

ABSTRACT Fuel use and resupply provisions are vital to all military combat operations, and any significant reduction in the amount of fuel required to sustain the force becomes a large tactical advantage for commanders Developers have been seeking methods that offer even small gains in fuel economy. Small gains for a fleet of thousands of vehicles translate into fewer fuel convoys to theater and large costs savings over time. The challenge to the tester and evaluator is to determine if these small advances are relevant or merely normally expected test variation in the acquired fuel consumption parameters. All too often only the mean fuel economy parameters are compared with and without the new equipment or process without considering test variances inherent in collecting the parametric data. The resulting analysis may then be seriously flawed. Hypothesis testing is a useful statistical method for comparing two sets of test data (sample means and standard deviations) to determine if

ABSTRACT Popularity of Advanced Driver Assistance Systems (ADAS) in the passenger car industry has seen an explosive growth in recent years. Some ADAS that are becoming ubiquitous are Lane Departure Warning (LDW), Blind Spot Detection (BSD) and automatic parking or parking assistance systems. In many cases, such systems had been developed specifically to handle the most demanding driving conditions at very high speeds, which typically require very sophisticated software and high-power hardware. However, in the other application areas or geographical regions, such sophistication often hinders adoption of the technology. An alternate approach is to use off-the-shelf (OTS) component as much as possible so that similar systems with an appropriate subset of functions can be developed cheaply and quickly. The approach similar to the NASA’s “PhoneSats” program is discussed in this paper

ABSTRACT The complexity of ground vehicle mission systems has evolved significantly over the last few years resulting in over-taxed platforms with federated mission suites. Department of Defense (DoD) is pursuing platform evolution toward integrated mission suites. Opportunities exist to apply aspects of previously developed methodologies from the aviation sector to ground platforms. This paper describes the parallels of the evolution of aviation platforms with the similarities to ground platforms. Solutions from the military aviation community will be discussed that could reduce development risks, schedules and costs and improve mission capabilities for ground applications. Specific discussion will be on opportunities and techniques to transition performance driven, high cost, low volume technologies into mission suitable and affordable high volume solutions. Discussion of the feedback opportunities into the aviation community will be addressed. This paper is not intended to be a

ABSTRACT For large populations of vehicles, it is often difficult to estimate how changes to scheduled maintenance plans will impact future operational availability, especially when component failure rates may not be known precisely or the operational environment changes. The primary objective of this contribution is to illustrate a Modeling and Simulation (M&S) approach which determines the minimum amount of maintenance necessary to keep a given threshold of operational availability. The analysis was performed using discrete-event simulation, maintenance data, and anecdotal information from technicians. The information was combined within a model containing over 15 variables including labor and process constraints. The analysis yielded a decision tool that can be utilized to assess several potential long term storage maintenance policies, focused on cost minimization while meeting readiness requirements

ABSTRACT Technology and innovation are growing at a rapid rate, placing increasing demands on military vehicles. With these advances come additional burdens to our ground vehicle systems due to escalating threats in areas such as situational awareness and cybersecurity. In order to deal with this ever-changing threat environment, additional computing resources are needed. Given the additional costs of high performance hardware, harnesses, software development, sustainment, and licensing fees, consolidation of resources can be essential in reducing costs. Leveraging today's latest technologies in distributed systems, advanced microprocessors, and accelerated graphics, this research proposes a solution to consolidate multiple crew stations into a single processing resource. Not only are these computing resources more powerful, they come at a more affordable price when configured properly. Citation: S. Sopel, M. Russell, K.

ABSTRACT In monolithic protection materials, a threat increase correlates to an increased material thickness. This is evident in V50 armor material specifications, such as Rolled Homogeneous Armor (RHA) MIL-DTL-12560K. This relationship translates to combat system level weight; the higher the performance, the higher the material weight, the higher the system weight. For ground combat systems, the total platform weight indicates relative protection. Hence, the M1 Abrams weight and protection level is greater than the Bradley Family of Vehicles, and the Bradley weight and protection level is greater than the M113. The weight procurement dollarization impacts are known during developmental efforts, but weight relationships also impact training and sustainment costs. Thus armor based weight changes have at least three cost relationships: procurement, training, and sustainment. These cost relationships are useful to understand in the context of the Army’s annual budget cycle. Citation: RA

ABSTRACT The M1 Abrams will be the primary heavy combat vehicle for the US military for years to come. Improvements to the M1 that increase reliability and reduce maintenance will have a multi-year payback. The M1 engine intake plenum seal couples the air intake plenum to the turbine inlet, and has opportunities for improvement to reduce leakage and intake of FOD (foreign object debris) into the engine, which causes damage and premature wear of expensive components

This study aims to explore the multifaceted influencing factors of market acceptance and consumer behavior of low-altitude flight services through online surveys and advanced neuroscientific methods (such as functional magnetic resonance imaging fMRI, electroencephalography EEG, functional near-infrared spectroscopy fNIRS) combined with artificial intelligence and video advertisement quantitative analysis. We conducted an in-depth study of the current trends in low-altitude flight vehicle development and customer acceptance of low-altitude services, focusing particularly on the survey methods used for market acceptance. To overcome the influence of strong opinion leaders in volunteer group experiments, we designed specialized surveys targeting broader online and social media groups. Utilizing specialized knowledge in aviation psychology, we designed a distinctive questionnaire and, within just 7 days of its launch, gathered a significant number of valid responses. The data was then

Vehicle electrification has gained prominence in various industries and offers sustainability opportunities, especially in the context of heavy-duty vehicles such as school buses. Despite the prevalence of conventional diesel school buses (CDSB), the adoption of electric school bus (ESB) and other eco-friendly alternatives is increasing. In the United States alone, there has been a notable increase in the adoption of ESBs, indicating substantial growth. The electrification of school buses not only promises energy savings, but also offers health benefits to children, reduced greenhouse gas emissions, and environmentally friendly transportation practices, aligned with broader eco-friendly initiatives. This paper investigates the potential for energy savings and reduction in environmental footprint through electrification of school buses in the Columbus, OH area. Analyzing current bus routes and road terrain data allows one to estimate energy demand and environmental impact, accounting

Dynamic wireless charging (DWC) systems can make up electrified roads (eRoads) on which electricity from the grid is supplied to electric vehicles (EVs) wirelessly while the EVs travel along the roads. Electrification of roads contributes to decarbonizing the transport sector and offers a strong solution to high battery cost, range anxiety, and long charging times of EVs. However, the DWC eRoads infrastructure is costly. This article presents a model to minimize the infrastructure cost so that the deployment of eRoads can be economically more feasible. The investment for eRoad infrastructure consists of the costs of various components including inverters, road-embedded power transmitter devices, controllers, and grid connections. These costs depend on the traffic flow of EVs. The configuration and deployment strategy of the proposed eRoads in Southeastern Canada are designed with optimized charging power and DWC coverage ratio to attain the best cost-effectiveness.

An SAE white paper on the different engineering approaches taken by traditional automakers and recent arrivals indicates that each category is remarkably aware of the others' strengths and weaknesses. Sven Beiker, a management lecturer at Stanford University, authored the report “Two Approaches to Mobility Engineering.” He gathered commentary from every corner of the vehicle ecosystem, from suppliers to software companies to manufacturers, and summarized the findings in a presentation at WCX 2024 in Detroit. Rather than “old companies,” Beiker likes to refer to traditional automakers as “incumbents.” Here are a few common observations from the report, which will be published this summer: Newer players are better at simplifying complexity, such as Tesla's ability to build vehicles with fewer parts. Older automakers are better at managing complexity, such as integrating disparate systems. Newer companies are constrained by financial resources and a shortage of available talent

Metal cutting/machining is a widely used manufacturing process for producing high-precision parts at a low cost and with high throughput. In the automotive industry, engine components such as cylinder heads or engine blocks are all manufactured using such processes. Despite its cost benefits, manufacturers often face the problem of machining chips and cutting oil residue remaining on the finished surface or falling into the internal cavities after machining operations, and these wastes can be very difficult to clean. While part cleaning/washing equipment suppliers often claim that their washers have superior performance, determining the washing efficiency is challenging without means to visualize the water flow. In this paper, a virtual engineering methodology using particle-based CFD is developed to address the issue of metal chip cleanliness resulting from engine component machining operations. This methodology comprises two simulation methods. The first is the virtual chip test

To promote real time monitoring, In use performance ratio monitoring “IUPRm” checks has been enforced in India from Apr’23 as a part of BS6-2 regulation. Since IUPRm is representative of diagnostic frequency in real driving conditions and usage pattern. therefore, a clear understanding of real-world driving is required to define IUPRm targets. This paper shares methodology and Validation steps for defining IUPRm routes for Indian market. Methodology objective is to standardize the market operating conditions over a particular region. Selected Methodology consist of three steps: For defining IUPRm route framework, first step is to have a pre-market survey to know current In use performance ratio “IUPR” status and improvement areas in existing market vehicles. Second step is to define market representative localized on road routes based on the finding of Pre-market survey. Third step is to validate defined IUPR routes and correlate the output in reference to coverage of market operating

Abstract The initial cost of battery electric vehicles (BEVs) is higher than internal combustion engine-powered vehicles (ICEVs) due to expensive batteries. Various factors affect the total cost of ownership of a vehicle. In India, consumers are concerned with a vehicle’s initial purchase cost and prefer owning an economical vehicle. The higher cost and shorter range of BEVs compared to ICEVs severely limit their penetration in the Indian market. However, government subsidies and incentives support BEVs. The total cost of ownership assessment is used to evaluate the entire cost of a vehicle to find the most economical option among different powertrains. This study compares 2W (two-wheeler) and 4W (four-wheeler) BEV’s cost vis-à-vis equivalent ICEVs in Delhi and Mumbai. The cost analysis assesses the current and future government policies to promote BEVs. Two assumed policies were applied to estimate future scenarios. Annual distance traveled, battery replacement assumptions, and fuel

The demand for electric vehicles (EVs) has been steadily increasing in recent years, led by the factors like environmental concerns, government incentives, and improvements in EV technology. The EV’s growth is expected to increase in the coming years as EVs become more affordable and more models become available on the market. Predicting the price of electric vehicles provides valuable insights on the EV market and inform a range of business, consumer, financial, and policy decisions. Predicting the price of electric vehicles using simple linear regression involves building a linear regression model with a single independent variable usually the vehicle’s characteristics or features to predict the dependent variable the price.This work has predicted the price of Electric Vehicle using a data set prepared for the Indian context. It has been predicted that there is significant correlation between battery capacity in Ah and the vehicle price. The measured RMSE value is 26274.942642891292

The global automotive industry’s shift toward electrification hinges on battery electric vehicles (BEV) having a reduced total cost of ownership compared to traditional vehicles. Although BEVs exhibit lower operational costs than internal combustion engine (ICE) vehicles, their initial acquisition expense is higher due to expensive battery packs. This study evaluates total ownership costs for four vehicle types: traditional ICE-based car, BEV, split-power hybrid, and plug-in hybrid. Unlike previous analyses comparing production vehicles, this study employs a hypothetical sedan with different powertrains for a more equitable assessment. The study uses a drive-cycle model grounded in fundamental vehicle dynamics to determine the fuel and electricity consumption for each vehicle in highway and urban conditions. These figures serve a Monte Carlo simulation, projecting a vehicle’s operating cost over a decade based on average daily distance and highway driving percentage. Results show plug

Climate change due to global warming calls for more fuel-efficient technologies. Parallel Full hybrids are one of the promising technologies to curb the climate change by reducing CO2 emissions significantly. Different parallel hybrid electric vehicle (HEV) architectures such as P0, P1, P2, P3 and P4 are adopted based on different parameters like fuel economy, drivability, performance, packaging, comfort and total cost of ownership of the vehicle. It is a great challenge to select right hybrid architecture for different vehicle segments. This paper compares P2 and P3 HEV with AMT transmission to evaluate most optimized architecture based on vehicle segment. Vehicles selected for study are from popular vehicle segments in India with AMT transmission i.e. Entry segment hatch and Compact SUV. HEV P2 and P3 architectures are simulated and studied with different vehicle segments for fuel economy, performance, drivability and TCO. The analyzed simulation results reveal similar fuel economy

In recent years due to significant increased cost of raw material, fuel and energy, vehicle cost is increased. As vehicle cost is one of the major factors that attracts prospective buyers, it has created specific demand for low weight and low-cost components than traditional components with better performance to meet customer expectations. Suspension is one of the critical aggregates where lot of material is used and reduction in weight tends to give lot of cost benefit. As suspension system derives vehicle’s handling performance, it has to be ensured that handling performance of vehicle is maintained the same or made better while reducing weight of the suspension. Advancements in simulation capabilities coupled with manufacturing technology has enabled development non-traditional leaf springs. One of such springs is mono-leaf spring without shackle. This type of leaf spring provides advantages such as low weight and nonlinear stiffness. Hence, this type of spring can cater the need of

Effective smart cockpit interaction design can address the specific needs of children, offering ample entertainment and educational resources to enhance their on-board experience. Currently, substantial attention is focused on smart cockpit design to enrich the overall travel engagement for children. Recognizing the contrasts between children and adults in areas such as physical health, cognitive development, and emotional psychology, it becomes imperative to meticulously customize the design and optimization processes to cater explicitly to their individual requirements. However, a noticeable gap persists in both research methodologies and product offerings within this domain. This study employs user survey to delve into children’s on-board experiences and utilization of current child-centric in-cockpit interaction solutions (C-SI Solutions), that over 50% of the interviewees (children) got on-board at least several times per week and over half of the parents would pay for C-SI

Medical and surgical instruments are utilized daily to save and improve lives. Because of this, they demand an exact level of accuracy and infallibility in their manufacture. Traditionally, aluminum and other metals have been the standard material of choice for medical and surgical instruments due to their weight, strength, durability, and cost benefits. However, new advances in technology are challenging the status quo and offering exciting new manufacturing possibilities that allow for greater material choices. One such advancement already making waves in the aerospace, leisure, and automotive industries — and poised to benefit medical and surgical manufacturing — is Additive Fusion Technology (AFT
As the world is moving toward optimized production strategies, third-world countries are also putting their efforts into contributing to this smart manufacturing approach. However, despite realizing the impact of its global significance and reduction in financial overheads, most of the third-world potential industries are hesitant to this transformation. The predominant reasons are huge capital investments and the cost of handling technology. In this study, a cost calculation methodology is recognized that analyze the cost benefits of technological investment. The case shows that the adaptation of Industry 4.0 is more economical than the traditional manufacturing approach. In an existing setup, a traditional TDABC is being applied, where cost id resources such as labor and material are included in a product cost at the end. This approach losses the visibility of associated labor and material cost used for the particular activity giving an offset in a product cost. Therefore, it is

This work aims at addressing the challenge of reconciling the surge in road transportation with the need to reduce CO2 emissions. The research particularly focuses on exploring the potential of fuel cell technology in long-distance road haulage, which is currently a major solution proposed by relevant manufacturers to get zero local emissions and an increased total payload. Specifically, a methodology is applied to enable rapid and accurate identification of techno-economically effective fuel cell hybrid heavy-duty vehicle (FCH2DV) configurations. This is possible by performing model-based co-design of FCH2DV powertrain and related control strategies. Through the algorithm, it is possible to perform parametric scenario analysis to better understand the prospects of this technology in the decarbonization path of the heavy-duty transportation sector, changing in an easy way all the parameters involved. The tool used is based on the truck longitudinal dynamics model to evaluate the power

Connected autonomous vehicles that employ internet connectivity are technologically complex, which makes them vulnerable to cyberattacks. Many cybersecurity researchers, white hat hackers, and black hat hackers have discovered numerous exploitable vulnerabilities in connected vehicles. Several studies indicate consumers do not fully trust automated driving systems. This study expanded the technology acceptance model (TAM) to include cybersecurity and level of trust as determinants of technology acceptance. This study surveyed a diverse sample of 209 licensed US drivers over 18 years old. Results indicated that perceived ease of use positively influences perceived usefulness, perceived ease of usefulness negatively influences perceived cyber threats, and perceived cyber threats negatively influence the level of trust

Through connectivity with the electric grid, electric vehicles (EVs) minimize or eliminate the need for fossil fuels. Despite the rapid adoption of EVs in recent times, most government adoption objectives have not been attained. This article aims to comprehend the reasons behind the limited uptake of electric scooters in India and the driving aspects. This research used a grounded theory methodology. Using a snowball sampling technique, we conducted 25 in-depth interviews with EV owners, mainly based in Delhi and Mumbai. As an outcome of the study, four drivers and four impediments to the adoption of EVs have been formulated. The study shows that there are Financial, Technological, Operational, and Psychological drivers and Technological/Infrastructural, Operational, and Psychological impediments to the adoption. The study identifies the key concern areas in the form of categories of drivers and impediments, which can be considered in industrial and public policymaking. This research
