Optimization of operating parameters of transport and storage complexes

When determining the operating parameters of transport and storage complexes, the necessity to choose an optimization criterion arises. A methodology for determining the optimal operating parameters of complexes, including methods of calculating the optimal amount of loading and unloading mechanisms and stations, is developed. Results of the research show that when calculating the optimal amount of loading and unloading mechanisms and stations it is advisable to take into account the ratio of arrival intervals of a rolling stock for loading and unloading, along with duration of the normative operating time for a single discharge mechanism. In order to determine the optimal number of loading and unloading mechanisms and stations in storage complexes, a criterion of minimum total expenditures of transport and storage enterprises for performing loading and unloading operations and transport organizations in relation with downtime of the rolling stock during loading and unloading operations is proposed. It is determined that economizing total expenditures of transport companies and a terminal complex when organizing unloading of an automobile transport by two loading means at one unloading station amounts to 23% compared to unloading at two stations.
