Performance-Based Cascading Failure Analysis of Cross-Domain Unmanned Combat System Considering Logistic Support

Abstract

Failure modeling and analysis are essential to the reliable and safe operation of unmanned combat system, which ultimately influence the success of a mission. Previous studies mainly focus on failure modeling and analysis of unmanned systems in a single domain, where synergy of cross-domain unmanned combat has rarely been considered. In this study, a multilayered heterogeneous network model for cross-domain unmanned combat system has been developed. In addition, the logistic support, which is another key aspect of any combat is incorporated. Given the interdependencies among the layers considering logistic support and cross-domain synergy, importance measure-based malicious attack model is proposed to reflect the intensive dynamics and high uncertainties under modern combat environment. Then, cascading failure analysis based on load-capacity model is conducted, which provides a load redistribution method considering cross-domain synergy. Finally, a case study is given for demonstration and verification, where the number of kill chains and load entropy are adopted as performance indicators.
