Research on Projection Gray Target Model Based on FANP-QFD for Weapon System of Systems Capability Evaluation

Abstract

The construction and evaluation of weapon system of systems (SoS) construction should start from the perspective of demand so that the system construction can better meet the actual demand. Based on the in-depth analysis of SoS architecture, an integrated framework for SoS requirements decomposition and capability evaluation is proposed. First of all, quality function development (QFD) is used to decompose the SoS requirements step-by-step. According to the house of quality mapping from missions to capabilities and performances, SoS evaluation indicator elements are determined and the requirement analysis framework is primarily formed. Second, the fuzzy analytical network process (FANP) is used to capture both symmetrical and asymmetrical relationships between the factors of each level in which priorities are calculated under subjective, vague, and uncertain preference information. And then, weighted by priorities of performance requirements that calculated by integrating FANP and QFD model, a projection gray target model is constructed for SoS capability evaluation under uncertain information and poor data. Finally, the proposed model is verified effectively and accurately by a case study, which provides an integrated method for both SoS requirement analysis and capability evaluation, and lays a theoretical foundation for system design and system optimization. Capability evaluation, fuzzy analytical network process (FANP), gray target model, quality function development (QFD), requirements analysis, weapon system of systems (SoS).
