This paper presents an innovative system architecture development framework that allows the search of optimum architecture solutions within large design space by automating certain model construction, alternative generation, simulation, and assessment tasks. Such framework is facilitated by a holistic modeling approach that combines the capabilities of Object Process Methodology (OPM), Colored Petri...
The existing methods to evaluate reliability of phased mission system with multi-mode failures are all very complex. In order to solve this problem, a simulation model based on CPN is proposed in this paper. Firstly, A CPN model of components with multi-mode failures is proposed; secondly, the CPN models to deal with dependencies are presented. On this basis, the phase reliability CPN model and mission...
It has been 10 years since the Department of Defense (DoD) first issued its architecture framework (DODAF). In the past we have shown that it is possible to take an architecture description that conforms to DODAF and convert it to an executable model to support rigorous evaluation. We now have a proof of concept that demonstrates the feasibility of making the conversion to the executable model automatically...
