In order to determine the optimum scheme of warship missile distribution path, a comprehensive matter element decision-making model was built. Combine the theory of fuzzy mathematics, matter element analysis, entropy and grey relation degree, based on consideration of multi-factors which influence object decision-making, fuzzy relation entropy matter-element of alternative path decision-making scheme was obtained, and an example was analyzed. The analysis result shows that this matter element model clear and brief, it can provide a fast and effective assistant decision-making means for commanding decision-maker.
