Analisys of sea transportation processes with network and simulation modeling

Abstract

The paper examines a complex of operations in sea transport using methods of network and simulation modeling. The authors consider the process of organizing sea transportation for the tanker fleet. In this case, the whole procedure is divided into four blocks of work. Each of the blocks is investigated separately using the network modeling method. The result of a private study is network models that describe the logic of performing a set of works, as well as the average execution time of all operations. It is proved that the use of simulation modeling for the analysis of the process of organizing and performing sea transportation makes it possible to assess the distribution of the execution time of the entire complex of works, as well as to identify bottleneck. The information obtained can be used for the subsequent analysis of the features of the work performance that reduce the efficiency of operations in the sea transportation process, and the development of possible solutions to improve the procedures under consideration.
