Abstract

Systems Engineers experience recurrent decisions on the same Technical Performance Measures, TPMs, during the overall systems life-cycle. The availability of a coherent decision framework allows identifying, implementing and evaluating effectiveness of the resulting Verification Validation and Testing strategy. It supports continuous improvement of the system and sustainable human factors integration. This paper proposes an application of Multi Domain Matrices in order to model the key aspects of repetitive decisions on the same TPM during the system life-time. It highlights how to manage evaluation, a coherent and effective decision process. The prior and quantitative evidences are updated by new evidences into the posterior and qualitative ones. The advantages and the cons of the selected approach in terms of representation, knowledge increase, sharing and evaluation are discussed.

Keywords: Model Based Systems Engineering, recurrent decisions, Verification Validation and Testing optimization
