Abstract: To solve the existing problems of pipe routing layout for aero-engines, a multi-objective optimization layout method of aero-engine pipe routing based on improved multi-objective firefly algorithm(IMOFA) is proposed. In the method, the multi-objective optimization layout mathematical model of aero-engine pipe routing is established, which takes the shortest pipe length, the least number of elbows, and the minimal energy value as the optimization objectives. Then, by combining with adaptive disturbance strategy and elite strategy, an IMOFA algorithm for multi-objective optimization layout of aero-engine pipe routing is provided, which realizes the multi-objective optimal layout of aero-engines pipe routing. Finally, the feasibility and effectiveness of the proposed method is verified by case studies.

Key words: aero-engine; pipe routing layout; multi-objective firefly algorithm (MOFA); elite strategy; non-dominated solution
