Proposal for Gemba-Kaizen Implementation to Enhance Efficiency in the Medium-Scale Bus Body Fabrication Industry2023-01-513202/23/2024
The basic needs of people are met by the building, fabric, and farming sectors. In addition, the automobile industry significantly contributes to human mobility and is essential to India’s economic expansion. There are numerous research strategies available to improve the bus body building industries. Several investigative approaches for enhancing bus body building industries are available. However, several of these studies merely look at it from the perspective of shop floor activity. Accordingly, when it comes to the execution of process design approaches, there is little practical evidence for accepting Gemba kaizen’s attitude. Hence, the purpose of this article is to present a continuous improvement redesign framework tailored to a specific bus body building industrial sector. The proposed model is structured after a critical examination of Gemba and Kaizen. The results showed that by implementing the improvement initiatives, the number of process activities decreased from 44 to 25

OBD Test Efficiencies Through Automation1333410/07/2022
In-vehicle automation efficiency improvements have successfully confirmed and enhanced model accuracy, saved significant calibrator time, and optimized vehicle utilization. While industry focuses on model-based calibration and Hardware-in-the-Loop (HIL) as replacements for in-vehicle testing, vehicle fleets are shrinking. Kaizen incremental efficiencies are often applied to manufacturing, yet there are significant opportunities for applying the continuous cycle of Kaizen activity to calibration and validation processes. OBD automation has progressed from all human testing to static break-out box circuit testing to CAN corruptions to LIN corruptions to SENT devices to dynamic performance/rationality diagnostics. Automating OBD validation enables rapid, repeatable vehicle operation without human inefficiencies. By integrating data collection tools, remote vehicle operation and OBD requirements, complete Design-of-Experiment (DOE) test sequences can be executed. 1. Intro 2. Automation

Implementation of Karakuri Kaizen in Material Handling Unit2015-26-007401/14/2015
Material handling is a major section in all the industries especially for delicate and huge components. Here in this industry they are using pneumatics system to tilt the component for certain angle so that operator will be able to do the further operation in the line. Pneumatic system needs compressed air for running the system, which in turn requires electricity to compress the air using an air compressor. Due to frequent power shutdowns many industries are facing problem to run their manufacturing unit peacefully. As an alternate they are using generators which require fuel to generate power. This adds excess cost for manufacturing the products and demand for fuel is also increasing day by day. So to avoid all this problem with a one step solution, dependability of energy resources has to be minimized. For avoiding the usage of energy resources the usage of pneumatics and compressed air has to be reduced. Karakuri kaizen which was first introduced by Japanese is system which is used

Lean and Safe - The Path to Sustainability in Product Design2011-01-125204/12/2011
Sustainability, Global Reporting Initiative, Corporate Social Responsibility, Lean, Continuous Improvement, Kaizen and “Green” are terms and initiatives that relate to each other as well as safety and environment, but often cause confusion. This paper first puts the various strategic issues into context to help participants better understand the “big picture” of strategic issues. The triple bottom line of sustainability (People, Planet and Profit or 3Ps) is a major issue for any organization. Attainment of sustainable growth demands continuous improvement in both manufacturing and design. The paper addresses how continuous improvement based on Dr. Deming's principles should be the benchmark for leading culture change. Included in this organizational culture change is occupational safety woven into the company's DNA. A relatively new concept, the marriage of lean and safety becomes the enabler for continuous improvement and long-term sustainable growth. Engineers and designers

Lean Engineering Center2009-01-088904/20/2009
Rybnik Engineering Center (REC) is the new R&D center developed by Tenneco in Poland. One of the key ideas behind the REC is to develop it based on the lean engineering principles. In a first step a white paper was established and agreed upon with senior management. This white paper consisted of: a vision a set of objectives derived from this vision and a road map to reach this vision The creation of REC has been articulated around 3 major themes: 1. PERSONNEL - It is about how to identify and hire people that will fit into our lean culture. A further challenge is to then train and mentor the people. A similar model known as the inverse-T at Toyota was implemented. Lastly, a network of partners has been established and integrated in the Tenneco development processes. 2. PROCESSES - Both engineering and cross functional processes have been systematically reviewed or new ones developed. With the help of the tool “Value Stream Mapping” the waste in existing processes was identified and

Lean Six Sigma Applied to Manufacturing Capacity Increase Project – Case Study2008-36-016610/07/2008
Nowadays, auto-parts companies spend a lot of efforts in trying to improve their manufacturing performance, which can be easily explained by the influence of many competitors, and also due to strong pressure besides their costumers to reduce prices of their products. Normally, the investments to buy new machines and contract new labors to respond customer demands gets lower as day goes by, due to this, the manufacturing team must use the best techniques available to get the maximum of their manufacturing system in an effort to meet flexibility, by the way, there is a constant effort to eliminate waste and variation in manufacturing system, for such work, many companies have adopted lean manufacturing principles in order to eliminate waste as a good response to produce more with less, and aligned with this thinking, Six Sigma methodology comes to add to lean manufacturing a robust way to eliminate variation on manufacturing process.

Ford still riding Six Sigma quality horseAUTOAPR04_0404/01/2004
Ford is combining Six Sigma with kaizen events at its plants around the globe to coax new ideas from its hourly workers in hopes of closing the gap with perennial vehicle-quality leader Toyota. Studies such as the annual J.D. Power and Associates Initial Quality Survey typically put Toyota Motor Corp. at the top, but middle-of-the-packer Ford Motor Co. will tell you that it's not because Toyota's hourly workers are “better.” End product quality is more a function of management's acumen than assembly line workers' abilities, according to Debbe Yeager, who has served in the position of Director of Consumer Driven Six-Sigma at Ford since February 2003 after serving as Director of Global Core Quality “The more I see, the more I think quality is a management initiative because the people on the line-and I've worked in the plants enough to know-will make a good product if you tell them that's what's expected of them,” she said

Standard Work – Lean Tools and Techniques2001-01-259809/10/2001
There are three key elements that must be in place before we can apply Standard Work. These elements are Takt Time, Standard Work Sequence, and Standard Work in Process. Once these elements are in place, the Kaizen cycle may be applied to your process. Several forms are used to help us identify and understand our Kaizen opportunities. They are the Time Observation Sheet, Standard Work Sheet, Percent Load Chart, and Standard Work Combination Sheet. Proper utilization of these forms will show people and part flow, standard work in process, takt time, line balance, and equipment utilization. Reviewing these forms, clearly posted in the work areas, will help identify where to focus Kaizen activities and expected results. Standard Work must be constantly monitored and revised as necessary to be a valuable tool, and it is vital to have the shop floor team members involved in the development of Standard Work from the beginning. There is a huge difference between the team members following
