Abstract
This research aimed to develop the efficiency of the current truck transportation management of the Songkhla branch distribution center of Sisahy Transport Co., Ltd. by using a mathematical model of the Vehicle Routing Problem (VRP) problem. Deciding on the transport route and route management for maximum efficiency in order to reduce transportation costs and increase the efficiency of transportation including improving work processes to be more efficient. The study found that the researcher collected data on freight trucks from January 2019 to December 2019 for a period of 12 months. There will be a total of 2 trucks, 56 transport trips, transport’s distance of 4,281.21 kilometers, and a total transportation cost of 25,404.95 baht per month. After the trial of a new truck route by metaheuristic method and improving basic solution by using 2-Opt method (2-Opt) through VRP Solver program, there will be a total of 6 bus routes, using a total of 1 truck, a total of 32 transport trips, transport’s distance of 2,679.60 kilometers and the total transportation costs of 15,900.88 baht per month, decreasing 9,504.07 baht per month, accounting for 37.41 percent.
