Abstract: Aiming to solve the problem of combat units' destruction and kill capacity discontinuity on the operation process under damage environment of joint battlefield, this paper provides an analysis, construction and resilience optimization method for the kill chain. Firstly, the paper proposes the resilience concept of kill chain, analyzes its characteristics and provides a new resilience metric. Then, based on the conception, with consideration of the description of meta path for kill chain and command and control（C2）organizational structure, this paper designs a method of analysis and construction for kill chain, and provides the optimized kill chain base for next resilience optimization. More, to efficiently solve the reconstruction of damaged kill chain under the environment, the paper provides a resilience optimization method based on the chain similarity measure. At last, the scientificity and efficiency of proposed methods and algorithms are verified by the designed joint operation scenario.
