A Vehicle Routing Problem Solving: The Case Study of Aluminium Extrusion Factory

Abstract

According to the case study of a manufacturing and aluminium extrusion factory, there has been no shared route used by the delivery trucks in sending customer orders. Additionally, products are also not filled completely within the trucks which adds to the cost of delivery. To reduce transportation cost, researchers using objective function and the LOGWARE program for planning the distribution. The information of 89 customers was used as a prototype in analyzing. The study found that the objective function could reduce manpower cost as well as ordering each truck to share the route for different customers. The distribution cost could be cut by 16.38 percent, resulting in a monthly savings of 181,392.36 baht.
