Multi-compartment Vehicle Loading and Route Optimization: Case for Exporting Thai Fresh Fruits

Supisara Krairiksh, Puwadol Oak Dusadeerungsikul

Abstract— Multi-compartment vehicles have been currently utilized in fresh fruit transportation because of their ability to consolidate perishable products without mixing them in the same chamber. In addition, each compartment can be set to a specific temperature to prolong the shelf-life of fruits. Nevertheless, the challenge of fruit transportation is to create an optimal route for vehicles, taking both transportation cost and fruit quality into account. The reason is that the quality of fruits has deteriorated when they are transported by the longer time options (which are typically less expensive). Therefore, an optimal vehicle route needs to balance transportation cost and fresh fruit quality. This article has developed a mathematical model for multicompartment vehicle loading and transportation routing to address such challenges. The model aims to minimize total transportation costs while maintaining the quality of fruits at the destination. The model has been validated using data from fresh fruit exports from Talaad-Thai (Thailand) to Nanning (China). Results indicate that desired quality at the destination directly impacts route decisions and total transportation cost. Meanwhile, the model reduces the number of vehicles required when multi-compartment vehicles are used instead of single-compartment vehicles.

Index Terms— multi-compartment vehicle, loading problem, shortest path problem, fresh fruit transportation mixed integer linear programming.
