Research on capability requirements generation of Weapon System-of-systems based on CRTAM model

The thoughts and methods of Capability-Based requirement analysis have gone increasingly deep into the development of Weapon System-of-Systems (WSoS). Effective analysis and programming of capability are fundamental tasks for requirement analysis of WSoS. Under the background of operation, there are repeating capabilities among different operational tasks. Acquiring Capability Index Requirements (CIRs) from various Operational Task Requirements (OTRs) is difficult. To resolve this problem, the value of each capability index is measured as an interval and Meta-activity model is proposed, the operational activity is decomposed to Meta-activity collections and the capability requirement of a single operational task is captured using Meta-activity-Capability mapping. Based on this, the WSoS Capability indices are divided into five kinds and four types of Capability Requirements Transverse Aggregation Model (CRTAM) are built to deal with the CIRs acquired from the tasks decomposition. A Capabilities Indices Requirements List (CIRL) under the multi-tasks condition is gained. Finally, the method is validated by an example of anti-stealth air defense systems of systems (ASADSoS).
