3.1.1 Model Lifecycle Management for MBSE

Abstract

AbstractModel Based Systems Engineering (MBSE) is an evolving practice in the early stages of adoption similar to the mechanical, electrical and software domains 20 to 30 years ago. Today there is increasing recognition of the potential MBSE brings to system life cycle processes with the increasing complexity of systems and the demands of the global marketplace. In order for the practice to realize this potential, system modeling and MBSE must be part of the larger model based engineering effort, and integrate with other engineering discipline models and modeling activities across the life cycle of a system. This is placing increasing demands on the need for Model Lifecycle Management (MLM) as an essential part of an MBSE infrastructure. This paper establishes the motivation for MLM, as well as laying the foundation for addressing challenges that lay ahead. The paper is focused on describing key concepts, requirements, current practices, and future directions of MLM, and setting the basis for more in depth overview of MLM solutions and vendor offering that are beyond the scope of this paper.
