Optimization of the Operating Parameters of Transport and Warehouse Complexes

Abstract

Abstract It is necessary to select the optimization criterion in order to determine operation parameters of transport and warehouse complexes. We developed a procedure for determining the optimal parameters for operation of the complexes. It includes methods of calculating the optimal amount of loading and unloading mechanisms and stations. The research findings show that when calculating the optimal amount of loading and unloading mechanisms and stations it is advisable to take into account the ratio of intervals of the rolling stock arrival for loading and unloading and the standard duration of one unloading mechanism operation. In order to determine the optimal amount of loading and unloading mechanisms and stations in warehouse complexes, we propose a cost-based criterion in the form of minimum aggregate costs for loading and unloading operations incurred by transport and warehouse complexes and the downtime of rolling stock in the course of loading and unloading operations incurred by shipping organizations. It has been found that the saving of the total costs and losses incurred by carriers and the terminal to organize the unloading of vehicles using two loaders at one unloading station is 23 % as compared to the unloading at two unloading stations.
