Abstract This research was conducted in order to simulate the night shift solid waste collection system of Phuket Municipality, Thailand. The Phuket Municipality faced the problems of residual waste and an unbalanced load for solid waste collection teams. The waste management committee of Phuket Municipality wanted to improve the solid waste collection system to run more efficiently. This research analyzed the volume of solid waste collection instead of the weight, and has separated the solid waste collection points into 11 “types”. The data was collected from the survey form. Minitab 16.1 was used to analyze and test the data distribution, and then used them to build the model. Microsoft Visual C++ was used to build the simulation model, which was then verified and validated extensively. The model represented the actual night shift solid waste collection system of Phuket Municipality. The heuristic approach was then employed to apply new assigned zones and routings. The results from the study of the new system of night shift solid waste collection system of Phuket Municipality shows that there is no residual waste and no unbalanced load between solid waste collection teams. The new system works effectively and can decrease the total number of trips for solid waste collection by 9.1 % and the average distance and time for the solid waste collection system are decreased by 7.42 % and 7.10 % respectively.
1 Introduction Phuket is a popular tourist destination in Thailand. There are historical landmarks and it has a beautiful natural scenery. The number of tourists, both domestic and foreign, is increasing exponentially every year. As a result, there is a rapid expansion of establishments such as hotels, restaurants, hospitals etc. These establishments also S.

pollute the environment and increase solid waste, especially in the Phuket Municipality. Solid waste management starts with collection, which is followed by transportation, processing and disposal or destruction. The collection and transportation of solid waste are considered very important, and accounts for 75 to 80 % of the total cost [3]. Therefore, this research is focused on the collection and transportation. It is essential to manage solid waste collection efficiency, to save time and costs. It is difficult to design a solid waste collection system to suit the garbage problems that is always changing. Simulation is the imitation of the operation of a real-world process or system over time [2]. In order to increase the vehicle productivity, it is necessary to plan vehicle routing so that the quantity of waste collec
