Abstract:
The research aims to; 1) compare the distance, time, and cost of the logistics from each warehouse carrier and, 2) select the warehouse from a suitable logistics operator for the case study company. This research applied a geographic information system to analyze the locations of 4 warehouse carriers selected by the case study company. By specifying the conditions for selecting a logistics operator based on the shortest transport distance and the least transport period. The result revealed that the selection of warehouse carrier D for inbound cargo and warehouse carrier a for the outbound cargo had the total shortest transport distance at 1,648.71 kilometers and the total transport period was 3,706.12 minutes. The comparison with the current selection of logistics operators, it was found that the case studied company selected logistics service from only warehouse A. Therefore, the case studied company could reduce the total transport distance by 849.96 kilometers and the total transport period is reduced by 983.79 minutes. It can also reduce the cost of inbound -outbound transportation by 32,555.00 baht. Since considered only the cost of both inbound -outbound transportation, the selection of logistics operators from warehouse D had the lowest transportation costs. The suitable selection of warehouse carriers will help the case studied company to manage both inbound and outbound shipments more quickly. And it can be conducted as a guideline in determining warehouse selection in the future.
