- Abstract:
-
Considering the storage location decision and optimization problems in automated storage and retrieval system, we propose a multi-objective logistics optimization algorithm, which considers various optimization objectives, such as the usage status of the pallet and dynamic changes in the allocable storage location. A multi-objective optimization model is established based on the equilibrium of roadway operations, the stability of the gravity center of shelves, and the shortest operation path. Based on the adaptive variation coefficients’ differential evolution algorithm, a random number encoding of the storage location is used to perform individual decoding according to the real-time feasible domain in response to the dynamic constraint condition. A Pareto optimal solution evaluation method based on the analytic hierarchy process is proposed to obtain the target weight related to the continuous optimization of a multi-batch operation, and a reasonable plan for the storage location decision is provided. The experimental results of the multi-batch operation show that the proposed algorithm is significantly better than the simple weighting algorithm, which can be effectively applied to dynamic location decision and optimization.
