Model-based Systems Engineering Supporting Cost Analysis of Aircraft Development Process

In the fact of increasing complexity of aircraft development programs, development processes of aircraft and their subsystems are continuously becoming complicated which leads to the growing risks of development cost across the entire lifecycle. In this paper, we propose a model-based systems engineering approach to support process modeling of aircraft development using a multi-architecture modeling language KARMA. At the same time, property verification and hybrid automata simulation are used implement the static cost analysis of each work task and dynamic cost analysis of the entire development process. Finally through one case study, a system-level aircraft development process ”V model” is created which cost analysis is implemented by the KARMA language. From the result, we find the KARMA language enables to integrate process modeling with static analysis and dynamic analysis of development process in a multi-architecture modeling tool MetaGraph.
