Liquid carbon dioxide marine vessel transportation scheduling optimization method

Abstract

The application discloses a liquid carbon dioxide marine ship transportation scheduling optimization method, which comprises the following steps: firstly, abstracting each node of a liquid carbon dioxide ship transportation link into a network node and an arc, constructing a logistics path network flow model and setting constraints; secondly, determining a standard transportation task set, generating a combined priority list through a saved value sorting, obtaining a transportation voyage set, and constructing a benchmark transportation ship scheduling model; finally, combining the network flow model to output a ship scheduling scheme; the application is aimed at the complexity of liquid carbon dioxide marine transportation, optimizes the matching relationship of each node in the transportation link, the path structure and the transportation capacity allocation mechanism through the network flow model, reduces redundant paths and invalid transportation behaviors, combines the voyage through the scheduling model to improve the ship loading rate, minimizes the transportation ship team scale to reduce the fixed cost, significantly reduces the resource waste caused by idle transportation capacity, improves the overall utilization efficiency of the ship team, and effectively reduces the operation cost of the liquid carbon dioxide marine ship transportation.
