THE OPTIMIZATION OF NON-DENSE LOADING PATTERNS OF PERISHABLE GOODS BY RAILROAD

摘要

The transport quality influences directly on the safety and quality of perishable goods. As to the loading of the perishable goods, the method of loading is one of the important techniques to ensure the quality of perishable goods. The well-established air circulation system should be established in a refrigerated transport vehicle or container and then the temperature can be under control. Based on the reality of perishable goods transportation on railroad, this paper takes the good air circulation system as the condition and sets the improvement of the capacity of the container as a goal, to build up the correspondingly mathematical model and hierarchical optimization strategy. According to the operation of the loading process of the perishable goods, a heuristic algorithm has been put forward to solve the problem. Compared with past experiences, the method is more effective.
