DEVELOPMENT OF AN OPTIMIZATION AND SIMULATION MODEL OF A WAREHOUSE COMPLEX

The article considers the author's approach to optimizing the configuration and operational strategies of an automated warehouse storage system based on Four-Way Shuttles (FWS/RS). The efficiency indicators of the business processes of the warehouse system are described. To solve the optimization problem, a simulation model and a set of simulation experiments have been developed that allows analyzing the impact of various factors and operational strategies on the system's targets. The simulation model allows you to choose the optimal combination of strategies for placing incoming goods in a warehouse, relocating blocking cargo, and assigning transport resources. The simulation model is developed based on a combination of discrete event-based and agent-based approaches. Special attention is paid to evaluating the system's performance under conditions of a stochastic input flow of orders of varying intensity.
