An Andromeda extension with shell commands based language over Open PSA

摘要

Working with large full scope PSA models may require appropriate tools to browse the models, to allow their modification, documentation and to perform export/import and merge procedures that cover the needs of version management and validation processes of large PSA models or parts of them. In this paper we introduce a shell based language that provides appropriate shell commands to handle PSA models and allow scripting over PSA-modules for systematic procedures and batch operations. This approach is based on an XML format between Scan-dpower RS-PSA format and the Open PSA Model Exchange Format. The introduction of a shell based language reveals new efficient opportunities of automating any kind of procedures when working with PSA models. Scripts can be developed in a generic way, what allows them to remain compact, readable and expressive at the same time. Their execution is reproducible, debug-able, testable and most important, efficient. Scripts can be considered for updating procedures (for instance for updating system fault trees when generated automatically via artificial intelligence tools), or for comparing and merging versions of a PSA models with divergent paths, for establishing the events cartography (to highlight dependencies over specific patterns), for revision and review procedures to allow easy and systematic and incremental search and validate procedures to ensure a better view of the nested structures withing a PSA model and for easy documenting edition.
