Keywords:Vehicle routing problem, LOGWARE 5.0, Objective function, Travelling Salesman Problem
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.
