Costs to replace obsolete parts are estimated to exceed $10 billion annually for military expenditures.¹ Other industries experience high costs related to obsolete parts as well.^2–5 Synergies between Model-Based Systems Engineering (MBSE) and modular design concepts should be leveraged to reduce those costs early in the design process. To date, obsolescence management, MBSE, and modularity have been studied, advanced, and presented in a mostly disjunct manner. Consequently, work to synergize these areas specifically to mitigate obsolescence impacts is lacking. The research presented herein illuminates that the untapped synergy at the nexus of obsolescence management, MBSE, and modular design can be leveraged to enhance strategic management of obsolescence. Borrowing from the modular software engineering “container” concept⁶, the MBSE container modeling approach presented provides systems engineers, architects, and designers with a novel method to influence the system design by minimizing the number of system modules affected by obsolescence. By applying this model-based strategic obsolescence management approach early in the system architecting and design stages, system engineering teams can reduce the associated complexity, lifecycle costs, and risk of obsolete parts replacement.

协同基于模型的系统工程、模块化和软件容器概念来管理过时

用于军事开支的更换过时零件的成本估计每年超过 100 亿美元。¹其他行业也面临与过时零件相关的高成本。^2–5应利用基于模型的系统工程 (MBSE) 和模块化设计概念之间的协同作用，在设计过程的早期降低这些成本。迄今为止，过时管理、MBSE 和模块化已被研究、推进和以一种大部分分离的方式呈现。因此，缺乏协同这些领域以减轻过时影响的工作。本文提出的研究表明，可以利用报废管理、MBSE 和模块化设计之间尚未开发的协同作用来加强报废的战略管理。借鉴模块化软件工程“容器”概念⁶，所呈现的 MBSE 容器建模方法为系统工程师、架构师和设计师提供了一种新颖的方法，通过最大限度地减少受过时影响的系统模块数量来影响系统设计。通过在系统架构和设计阶段的早期应用这种基于模型的战略性过时管理方法，系统工程团队可以降低相关的复杂性、生命周期成本和过时部件更换的风险。
