Multi-objective optimization and multi-attribute decision making of MLRS composite materials direction pipe

Based on the finite element analysis method and optimization method, a multi-objective optimization model of MLRS composite materials direction pipe is established for the structure design requirements, by using nondominated sorting genetic algorithm II (NSGA-II) on Pareto. The Pareto-optimal solution set of direction pipe is obtained by optimization solution, then decision matrix is constructed by the set. The multi-attribute decision making (MADM) is carried to rank the Pareto-optimal solutions and determine the best solution, using technique for order preference by similarity to ideal solution (TOPSIS) method. A comparison of the direction pipe's properties by using specific stiffness structural efficiency indicates that the optimization design is effective.
