Highlights A multi-objective mixed integer program is proposed for the multi-load automated guided vehicles (m-AGVs) scheduling problem. Real data informs the relationship between m-AGVs’ energy consumption and payload weight, integrated in the proposed model. The partial charging process of m-AGVs is incorporated into the scheduling model.
Abstract The widespread implementation of modern logistics has led to the extensive use of multi-load automatic guided vehicles (m-AGVs) in automated sorting centers. This paper tackles one of the most challenging problems in this context, i.e., the scheduling of m-AGVs for express package handling. We comprehensively consider the loading and unloading delay of packages and energy consumption of m-AGVs, formulating the problem as a multi-objective mixed integer program (MO-MIP). To solve the proposed optimal scheduling problem, we apply the Non-dominated Sorting Genetic Algorithm (NSGA-II). A series of simulation experiments on three sorting centers have been further conducted to demonstrate the effectiveness and efficiency of the proposed model and solution algorithm.
