Abstract
An efficient transport logistics system is much important for Thailand’s fruit exports because the export process consumes the time, cost and energy immensely. The fruit season comes with the increasing demand for container and trailer services as road transport is often the most flexible and common mode, resulting in substantial increase of transportation costs due to the shortage of export containers and trailers. Besides, road transportation significantly contribute to air pollution and the environmental impacts. This paper presents a methodology to improve efficiency to promote export of Thai fruits through minimizing costs and energy consumption for environmental considerations. A developed Multi-Objective Linear Programming (MOLP) model was applied for a case study investigation involving Thai mangosteen exports. Assuming an operator or exporter has five production sites domestically and fresh products must be exported overseas to five destinations. The results demonstrated the new routes set can reduce transportation costs by 8.82%. Considering different costs of transporting and its energy efficiency, the sensitivity analyses were also carried out in this study.
