Abstract:
This research is to study the vehicle routing arrangement for automotive parts: a case study of Automotive Parts Transport Company. Quantitative research is applied that is to analyze the vehicle routing arrangement and to compare the transportation costs before and after vehicle routing arrangement. The transportation routing data was collected on August to November 2020. The three transportation routing zones (Zone a, Zone b and zone c) were divided into five routes each, for a total of 15 routes. The saving algorithm is applied to compare the total transportation cost before and after using a saving algorithm. The results of the research showed that the saving algorithm can reduce the total cost of transportation by 4,241,705.71 baht per year or 23.33%, total distance by 395,740.8 kilometers per year or 18.83%, total transportation time by 438,766.89 minutes per year or 17.37%, and total fuel volume by 65,956.8 liters per year or 18.38%. Moreover; the number of trucks is decreased by four cars or 26.67% and the number of employees is decreased by eight people or 26.67%.
