Capability requirement planning of Weapon System-of-systems based on Interval Weighted Constraint Network

Capability-Based requirements management and planning thoughts and methods have gone increasingly deep into the development of Weapon System-of-Systems (WSoS). In the traditional top-to-bottom capability requirement planning (CRP) methods, the constraints among different capabilities indexes acquired from the tasks decomposition are neglected, which leads to the irrationalities and conflicts between different WSoS capability requirement indexes. Based on the analysis and description of capability requirements planning problem, the constraints are divided into five types and extracted from WSoS according multiple views thoughts. In addition, Interval Weighted Constraint Network (IWCN) is introduced and a consistency detection algorithm and a conflicts elimination strategy are proposed to achieve a capabilities requirement plan satisfying the tasks requirements and the capabilities indexes constraints. Finally, the practical applicability within a Joint Operations System of Systems (JOSoS) based on the space force capability requirement scheme planning is demonstrated, which proves the validation of the method built in this study.
