Economic evaluation of university welfare transportation in Kasetsart University, Kamphaeng Saen Campus

Abstract

This research aimed to analyze costs and the replacement of welfare transportation assets in Kasetsart University, Kamphaeng Saen Campus. The assets consisted of shuttle bus no. 1-5, biodiesel vehicles no. 1-7, and biodiesel vehicles modified from vans with registrations 3Y-3606 and 8M-9575. In the cost analysis, activity-based cost analysis was used by determining the activities that occur in providing services, including 1) service 2) maintenance 3) activities, and 4) car condition checking. The replacement of assets were analyzed by replacing old vehicles with new vehicles using two options: 1) order a custom-built car from the factory, and 2) assemble the car. The results of the study were found that the cost of service of shuttle bus no. 1 had the highest cost of 47.04baht/km, while the lowest cost was for the biodiesel vehicles with registration numbers 3Y-3603 and 8M-9575, with a cost of 19.62baht/km. The activity with the highest cost was service. The major cost components contributing to this high cost were fuel and depreciation, accounting for 69% and 31% of the total cost, respectively. For property replacement studies, this research was analyzed using the equivalent annual worth. The results of the analysis were found that the alternative approach of assemble the car had an annual cost equivalent to 189,740baht/year, which was less than the cost of ordering a custom-built car from the factory. In addition, the sensitivity analysis of choosing to assemble the car show that the variables with the greatest effect on the NPV value were the service life and total cost, resulting in an increase in the NPV value in the range percentage of 22-25.
