摘要
A picking route optimization model was established and the distance matrix for the storage location in non-traditional warehouse was constructed according to the characteristics of a non-traditional fishbone layout and considering the actual warehouse operation constraints. Meanwhile, a MPGA with an evolutional reversed operator was proposed based on the standard genetic algorithm (SGA) to overcome the premature convergence and poor local search ability of SGA. To verify the effectiveness of the algorithm, MPGA was compared with SGA and S-Shape under different order sizes, and the MATLAB software was used to simulate and analyze. Experimental results show that the MPGA has the best calculation results, and the speed of searching optimal solution is quicker than that of SGA. The proposed algorithm may be better to solve the problems of picking route optimization for the warehouse with fishbone layout and improve the intelligent level of warehousing. © 2020, China Mechanical Engineering Magazine Office.
