WAREHOUSE SERVICE PROVIDERS SELECTION BASED ON GIS A CASE STUDY OF AN AUTOMOTIVE PARTS MANUFACTURER

Abstract

The objectives of this research were (1) to analyze and compare the distance and delivery time from each warehouse service provider and (2) guidelines for deciding the warehouse service providers for the case study company. This research applied a geographic information system (GIS) to analyze the locations of 4 warehouse service providers selected by the case study company, the locations of Laem Chabang Port and the location of the case study company which is an auto parts factory. By specifying the conditions for selecting a logistics operator based on the shortest transport distance and the least transport period. The result revealed that warehouse A, currently chosen by the case study company, was the most suitable warehouse under the conditions of the shortest transportation distance. However, warehouse D showed the shortest total lead time under the minimum lead time conditions. In addition, when analyzing inbound - outbound freight transport model using the frequency of transport. It was shown that the selection of warehouse D for inbound logistics and warehouse A for the outbound logistics had the total shortest transport distance of 1,648.71 km and the total transport period was 3,706.12 minutes. Therefore, if the case study company chooses this alternative, it would be able to reduce the total transport distance. The case studied company could reduce the total transport distance of 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.
