One universal method of complex system reliability, maintainability, supportability, testability quotas design and trade‐off based on improved flower pollination algorithm

Abstract

For modern complex system, quality has become a serious and difficult problem that restricts the generation of combat effectiveness. Withal, based on domestic and foreign research and analysis, this paper puts forward a trade‐off method for complex system reliability, maintainability, supportability, testability (RMST) design, which is suitable for product design stage. First, aiming at the uncertain problem of complex system constrained optimization, the good‐point set population initialization, Deb feasibility comparison method and ε constraint method are integrated into the flower pollination algorithm, to construct the algorithm for RMST quotas design and trade‐off. Second, taking the typical series‐parallel repairable system as an example, one general model for complex system RMST quotas design and trade‐off based on effectiveness is constructed. Finally, take an unmanned nuclear radiation detection system as a typical case, to verify its feasibility, advantages, and disadvantages.

Construction of the RMST Indicator System for Aeronautical Complex Equipment Based on Correlation Analysis and Fuzzy-rough Set Theory

“…The mass-selection of RMST indicators combines the principle of "O-C-W-I-S-D" based on common international standards [11], Chinese military standards [12], high-frequency key indicators in the paper [1,13], and the high-frequency key indicators mentioned by the experts of the cooperative units. The mass-selection set of RMST indicators for aeronautical complex equipment is shown in Table 1.…”

“…Current research is focused on optimizing the RMST performance of aeronautical complex equipment to further improve its operational capability and combat readiness integrity. The RMST refers to reliability, maintainability, supportability, and testability [1]. The construction of the RMST indicator system refers to the analysis of the importance of many underlying indicators around the RMST, screening out the representative indicators that have an important impact on the RMST, and building a reasonable and efficient RMST indicator system.…”

“…Li Y [5] systematically carried out research on the optimization of the indicator system based on the rough set theory, using attribute simplification to eliminate redundant indicator, which has the characteristics of operability, generalization as well as scalability. Zhan X [6] Aiming at the problems related to complex equipment RMST research, most researchers skip the RMST indicator system construction link to directly carry out the RMST trade-off problem research, ignoring the reasonableness and scientificity of the RMST indicator system construction on the RMST trade-off research lay influence [1].…”
