摘要

Complex Engineered Systems generally operate in uncertain environments. Uncertainty can affect the system value delivery through different ways. Viability is the Modern non-functional properties represented as a response to de- creasing the impact of dynamic complexities on systems value delivery, therefore system designers used viability principles as an option for executing a design decision or feature in order to respond to variations in the operational context. As there may be numerous system architectures based on different adaptable options, assessing the viability of these architectures under uncertainty as for the basis of compression and selecting the optimized one is an impor- tant problem now a day. In this paper for surmounting above problem, a 9 step model is proposed which calculate the viability of assumed architecture under uncertainty by representing the regions in the system that is mostly impacted by the operational uncertainties. To represent the applicability of proposed model a simplified example of Synthetic Aperture Radar satellite observed, the viability of assumed system has been calculated and then some viable options imposed to the system architecture. The recalculated viability value of the assumed system and monitoring of all process steps by experts have shown the applicability and logicality of the model.
