In order to solve the problem of time consuming,low accuracy and low efficiency in scheme optimization and evaluation of solid rocket multi-stage combined design with multiple indexes,multiple attributes and multiple schemes,a multi-attribute evaluation method of technique for order preference by similarity to ideal solution（ TOPSIS） is introduced on the basis of the concept of information entropy and the principle of variable weight synthesis. An evaluation model of solid rocket multi-stage combined scheme optimization is established by the information entropy theory of the variable weight synthesizing and compromise state variable weight vector. The combined schemes of solid rocket are evaluated,sorted and selected. The example shows that the information entropy weight TOPSIS method can effectively solve the problem of solid rocket multi-stage combined scheme evaluation,sorting and selection. The method can achieve the purpose of rapid design.Compared with the traditional optimization method,it has the advantages of fast,flexible and reliable.
