VEHICLE ROUTING FOR TIRE TRANSPORTATION IN THE EASTERN REGION OF THAILAND BY USING THE SAVING ALGORITHM A CASE STUDY OF ABC COMPANY LIMITED

Abstract

The objectives of this research were to study the routing of transportation tires of ABC Co., Ltd., to compare the routing between the original method of ABC Company Limited and the saving algorithm method. In order to devise solutions and develop the transportation routing to achieve the most efficient path.

            The results of this study found that ABC Company Limited's tire transportation route arrangement uses only one distribution point. The pick up trucks were used for delivery to customers in Chonburi Province. There are 5 cars in total.  Each car can make 2-4 routes per day, with a maximum load of 3-4.5 tons per vehicle. For longer distance such as transportation to Chachoengsao, Prachinburi and Sa Kaeo provinces 6-wheel vehicle were used. The distribution is from Monday to Saturday, but greatest on Mondays, Tuesdays and Thursdays.  A total of 5 vehicles are used to distribute products each day, able to distribute products on 2 to 4 routes.

In total of 2 vehicles, each one can deliver around 3-5 stores per day. which will carry no more than 9-10 tons. The distribution route between each provinces in the east, the overall distance before calculating Savings s(i,j) for 12 months, equivalent to 307,915.20 kilometers, after calculating, Saving s(i,j) the overall distance in 12 months is 20,688 kilometers, which is reduces by 6.72%.
