- Abstract
A task scheduling integrated optimization method based on dynamic storage allocation strategy is proposed to solve the energy consumption optimization task scheduling problem of automatic stereo warehouse with stacker. This strategy allows the reuse of empty storage locations generated by picking in the current task execution batch, resulting in task sequence constraints. Combined with the calculation difference of stacker’s running time under different motion states, a scheduling model with the goal of minimizing the total energy consumption of stacker task under compound instruction is established. According to the characteristics of the model, an improved imperialist competition algorithm is proposed to solve the model, which can satisfy the task order constraint by setting the correction mechanism, and the concept of alien population invasion is introduced to avoid the algorithm falling into “premature”. Finally, the task scheduling algorithm proposed in this paper is verified by two groups of data. The experimental results show that the proposed scheduling algorithm is superior to other methods in energy consumption and task execution efficiency, and can effectively reduce energy consumption and improve operation efficiency of stacker.
