Architecture Definition in Complex System Design Using Model Theory

Architecture definition, which is central to system design, one of the two most used technical processes in practice model-based systems engineering. In this article, a fundamental approach architecture definition presented and demonstrated. The success its application engineering problems depends on precise but practical term architecture. standard for description, ISO/IEC/IEEE 42010:2011, was adopted that has been subsumed into later standards. 2018, working group JTC1/SC7/WG42 began review holding sessions late year. This article extends complements position paper submitted during meetings, Tarski model theory ISO/IEC 24707:2018 (logic-based languages) were better understand relationships between models concepts related Independent from group, it now contributes intuitive definitions terms are specify mathematically based process definition. utility benefits complex design demonstrated diesel engine emissions reduction case study.
