Systems Engineering is a method for developing complex products, aiming to improve cost and time estimates and ensure product validation against its requirements. This is crucial to meet customer needs and maintain competitiveness in the market. Systems Engineering activities include requirements, configuration, interface, deadlines, and technical risks management, as well as definition and decomposition of requirements, implementation, integration, and verification and validation testing. The use of digital tools in Systems Engineering activities is called Model-Based Systems Engineering (MBSE). The MBSE approach helps engineers manage system complexity, ensuring project information consistency, facilitating traceability and integration of elements throughout the product lifecycle. Its benefits include improved communication, traceability, information consistency, and complexity management. Major companies like Boeing already benefit from this approach, reducing their product
Abstract The Integrated Systems Engineering Framework (ISEF) is an RDECOM solution to capture, leverage, and preserve/reuse Systems Engineering (SE) knowledge generated throughout a system’s lifecycle. The framework is a system of tools designed to support decision making with confidence through embedded SE process management, high quality data visualizations, and system lifecycle information traceability. A web based tool architecture supports near zero IT footprint and allows real time collaboration between team members. The Combat Vehicle Prototype program is a large S&T effort within the Army community to create a virtual demonstrator to influence the next Future Fighting Vehicle program of record. The program is made up of “leap-ahead” technology development efforts pursuing TRL 6 demonstrations. These technologies are being coordinated with the CVP central program office to ensure an effective system level concept is transitioned at the end of the program. This paper will begin
ABSTRACT The Advanced Systems Engineering Capability (ASEC) developed by TARDEC Systems Engineering & Integration (SE&I) group is an integrated Systems Engineering (SE) knowledge creation and capture framework built on a decision centric method, high quality data visualizations, intuitive navigation and systems information management that enable continuous data traceability, real time collaboration and knowledge pattern leverage to support the entire system lifecycle. The ASEC framework has evolved significantly over the past year. New tools have been added for capturing lessons learned from warfighter experiences in theater and for analyzing and validating the needs of ground domains platforms/systems. These stakeholder needs analysis tools may be used to refine the ground domain capability model (functional decomposition) and to help identify opportunities for common solutions across platforms. On-going development of ASEC will migrate all tools to a single virtual desktop to promote
ABSTRACT Systems Engineering is an interdisciplinary approach that concentrates on the design and application of the whole as distinct from the parts. For complex systems, this includes the challenge that the behavior of the system as a whole is not intuitively understood by understanding the components. Classic System Engineering models establish a perception of a beginning and an end of the systems engineering process. Unfortunately, a long period between product launch and discovery of unexpected behavior for systems may occur with a protracted lifecycle. A Systems Engineering approach based upon the “control theory” model establishes a high correlation between interdisciplinary models to facilitate feedback throughout the system lifecycle to tune capabilities to user satisfaction. This close coupling extends well beyond tracing of requirements to qualification testing fulfillment as practiced in the traditional “V” model. The system itself is a traceability link providing lifecycle
ABSTRACT Prototype Warfare represents a paradigm shift in how the US Department of Defense (DoD) executes acquisition of defense systems in a manner that is significantly faster than traditional acquisition. At its core, Prototype Warfare shifts focus from large fleets of common one-size-fits-all exquisite systems to small quantities of rapidly fielded, highly tailored systems that are focused on specific capabilities within a specific theater to address a specific (and typically urgent) requirement. This paper does not address the programmatic or policy implications of implementing Prototype Warfare, but instead provides an approach to achieving Prototype Warfare from a technical perspective. The key to executing a Prototype Warfare program is to establish and execute a robust Mission Engineering practice that uses the operational context of a system to drive performance requirements, allowing the modeled end use of the system to be root of all requirements traceability. “Success no
The IncQuery AUTOSAR-UML Bridge is an innovative solution for Assisted Documentation Creation and Automated Handover, aiming at driving a paradigm shift in integrated digital engineering in the automotive domain. The AUTOSAR-UML Bridge is addressing a well-known gap in the engineering ecosystem of automotive design, where the co-design of AUTOSAR models and other model-based artifacts is often hampered by tedious workflows involving manual syncing of model contents between AUTOSAR and UML/SysML tools. The Bridge is aiming at streamlining the workflow by generating high-quality UML models from AUTOSAR projects, with built-in ISO26262 and ASPICE compliance. Automotive software architects and systems engineers spend a lot of time with creating ISO26262-compliant documentation, by creating UML models from AUTOSAR architecture designs, or establishing traceability between requirements captured in SysML and design artefacts that exist in both modeling languages. However, as a project
In support of developing complex systems, integrating requirements from various source standards, such as the Military Standard (MIL-STD) series and others, presents a significant challenge. This paper explores the development of Model-Based System Engineering (MBSE) Systems Modeling Language (SysML) projects that incorporate MIL-STD requirements. The study begins by defining the critical need for integrating multiple standards into MBSE projects, emphasizing the importance of adhering to MIL-STD requirements when invoked by the customer. The study further defines the limitations inherent in managing standards independently and propose a unified approach within a SysML-based framework. The research introduces a systematic methodology for mapping MIL-STD requirements and other relevant standards onto SysML constructs, ensuring traceability and consistency throughout the system development lifecycle. Comparing traditional methods with the use of MBSE methods highlight the advantages of
The automotive industry has seen accelerating demand for electrified transportation. While the complexity of conventional ICE vehicles has increased, the powertrain still largely consists of a mechanical system. In contrast, vehicle architectures in electrified transportation are a complex integration of power electronics, batteries, control units, and software. This shift in system architecture impacts the entire organization during new product development, with increased focus on high power electronic components, energy management strategies, and complex algorithm development. Additionally, product development impact extends beyond the vehicle and impacts charging networks, electrical infrastructure, and communication protocols. The complex interaction between systems has a significant impact on vehicle safety, development timeline, scope, and cost. A systems engineering approach, with emphasis on requirements definition and traceability, helps ensure decomposition of top level

As the demands of traceability and compliance are put on manufacturers, using a laser provides permanent marking of a variety of information, including 2D bar codes, serial numbers, company information, and logos
The use of lasers to mark surgical instruments has become of greater significance, however, the parameters used in these applications are not always fully appreciated. The medical industry, in particular, has utilized laser technology primarily to mark, weld, and cut medical devices for years. Lasers address the need for microscopic applications: to cut widths measurable in microns, spot welds with heat affected zones barely visible to the unaided eye, and highly resolved biocompatible markings that enable traceability of instruments and implants. In common with other industries, medical devices and pharmaceutical businesses turn to lasers for a one-step, fast, flexible, permanent, and a highly automated marking process
