Abstract

Location of warehouse and distribution center is a major factor of transportation cost. As such, locating warehouse or distribution center proximity to final customers will help to transport products to those customers more convenient and faster. However, it might affect total transportation cost if there are too many distribution centers. Currently, Thailand Post Distribution Co. Ltd., a third party company, which is responsibility to send drugs and medical supplies to final customers in various provinces around the country. The company has one warehouse locating in Samut Prakan province and nine distribution centers locating in various regions. In the past, the company does not have any investigation about where to locate a warehouse location and distribution centers and the number of optimal number of those facilities. As a result, the objective of this research is to find suitable locations of a warehouse and distribution centers for this company in order to transport products to final customers with the lowest transportation costs using mathematical model.  Analysis results via processing with LINGO software revealed that the company should have one warehouse locating in Samut Prakan province and twelve distribution centers which will reduce transportation cost by 1,343,170 baht per month or 6.1%.
