Abstract

The paper is devoted to the solution of the actual scientific task of increasing the efficiency of the warehouse complexes functioning by means of simulation modeling. On the basis of the analysis of recent studies, it was established that the main criterion for the effective operation of any warehouse is providing necessary cargo circulation with optimal costs for processing and storing goods. It has been proven that warehouses belong to complex systems, in which the possibility of applying traditional methods of finding optimal solutions is limited, therefore, modern research methods must be used to justify management decisions during the development or modernization of warehouse operations. One of these methods is simulation modeling.

A modern warehouse complex located in the city of Dnipro was chosen as the object of the study. To analyze the possibilities of increasing the reliability of its operation and reducing capital and current costs during operation, a simulation model was developed in the AnyLogic environment (developer The AnyLogic Company). The developed model consists of two elements. 1. The transport network for the movement of cars, forklifts and racks placement in warehouse areas in accordance with its layout scheme. 2. Process diagram, which represents a sequence of 114 blocks of the AnyLogic process modeling library, which cause the logic of warehouse operation. 2.

The presentation of the developed simulation model in the form of a black box allows studying the influence of the input and output parameters of the warehouse on the efficiency of using its resources. A simulation experiment algorithm was proposed, it consists of a triple nested cycle of varying the main warehouse parameters: the number of loading and unloading docks, as well as the number of forklifts in the storage area. The total number of model calculations was 63 variants. According to the results of the performed simulation, 4 variants of the warehouse operation were established, which ensure the fulfillment of its daily cargo turnover. For the final assessment of the obtained results, the structure of a complex criterion was proposed, which takes into account the total number of forklifts operated in the warehouse; the average utilization rate of forklifts; the average duration of loading and unloading cars; the average waiting time for cars being loaded and unloaded.
