Focusing on solving the problem of the evaluation and optimization for time sensitive target kill chain, the basic concept of time sensitive target kill chain is first elaborated, and its five basic combat links are clarified, and a kill chain structure model is established; Then design an evaluation index system from three dimensions: closure time, damage index, and strike cost; Drawing on the service concept of optimal route recommendation on intelligent travel platforms, four dynamic optimization strategies have been explored and proposed, and specific calculation ideas and methods have been analyzed and provided; Finally, typical combat scenarios were designed to conduct case analysis, and the data results verified the rationality and feasibility of the proposed strategy.
