System synthesis models as a standard DoD tool for automatic test system analysis, selection, and development

System synthesis models (SSM+), a critical part of the consolidated automated support system (CASS) introduction planning process, is also used as a valuable decision support tool in the automatic test system (ATS) selection process. SSM+ is used to identify the limitations of various candidate ATS for supporting a weapons system platform or set of Units-Under-Test (UUTs). SSM+ can be used to identify potential ATS product improvement efforts and to assist in the development of reconfigured or downsized ATS stations. A potential application of SSM+ addressed herein is the assignment of UUTs to operational test program set (OTPS) groups based on common mechanical interface requirements and exceptions as well as the development of a family of common interface devices. Although only military examples are discussed herein, SSM+ would have similar potential applications in the commercial world.
