The invention discloses a matrix production workshop-oriented heterogeneous multi-load AGV scheduling method and system, and belongs to the technical field of automatic logistics scheduling. The core of the method is to construct a multi-objective optimization model which aims at minimizing task total delay time and the total number of path conflicts, and a multi-group evolution combined adaptive neighborhood search (MPE-ANS) algorithm is adopted for solving (the flow is shown in figure 1). According to the algorithm, a total population is divided into sub-populations, excellent individuals and common individuals are distinguished, and a targeted evolutionary strategy is designed: the excellent individuals realize local accurate optimization through three neighborhood structures, the common individuals expand a search space by virtue of crossover and mutation operators, and meanwhile, non-dominated solutions are dynamically stored through external archives. The method adapts to heterogeneous multi-load AGV operation characteristics, effectively balances global exploration and local optimization capabilities, remarkably reduces task delay and path conflicts, and is suitable for multi-AGV collaborative transportation in scenes such as intelligent factories and automatic warehouses.
