An Emergence Analysis Method for System of Systems Capability Items Based on Soft Set

Abstract

Oriented emergence new capability items for system of systems (SoS), a measurement model for SoS capability items emergence was proposed in this paper. The soft set which has obvious advantages in dealing with the uncertainty problem based on the nature of its data, as well as measuring attribute significance and knowledge dependence. The decision division between component objects set of SoS and capability items set has been defined by the adopt soft set. The importance of the emerging capability items in the overall SoS is analyzed through changes in decision division in order to obtain the measurement of SoS capability items emergence, then the measurement method for SoS capability items emergence is formed. A case study is then conducted to verify the effectiveness of method.
