Abstract:
The objectives of this study were: 1) to find a distribution center location that
suitably, conveniently and efficiently meets the needs of customers of the Case Study
Company, 2) to apply the appropriate methods of evaluating location alternatives for
selecting the distribution center location for the Case Study Company, and 3) to analyze
the decision to choose a suitable distribution center location in the Bangkok Metropolitan
region for the Case Study Company.
This study is based on operations research which has the scope of the area used
to analyze the distribution center location in the Bangkok Metropolitan Region. Three
methods of evaluating location alternatives were applied together, namely Center- of-
Gravity method, Load-Distance method, and the Factor-Rating method.
The results of the study showed that the Center- of- Gravity method determined
the optimum location coordinates to be in Bang Khen district, Bangkok, which is a built
up area and therefore not suitable for establishing a distribution center. By applying the
Factor- Rating method together with the Load- Distance method, through asking the
executives to determine the location of interest and weight the importance of each
factor, it was found that the highest weighted score of 0. 68 was on Bangna- Trad road.
Then, using the location from the first 3 highest weighted scores analyzed with the Load-
Distance method, it was found that the location with the lowest total load- distance
value was on Ratchaphruek road, Nonthaburi, which is equal to 2,951,482.40. Therefore,
the appropriate location for deciding to establish a distribution center in the Bangkok
Metropolitan region for the Case Study Company is Ratchaphruek road, Nonthaburi,
specifically fixed by the geographic coordinates, latitude 13. 8764518° and longitude
100.4393312°.
