In this study, The Optimal Number of buses for Kuwait Public Transport Company (KPTC) was determined. Integer linear programing model for the general problem was developed first. A case study where this model was applied to Kuwait Public Transport Company was considered. It is important to mention that the most important five routes were selected using Pareto analysis. Finally, the optimal annual profit was computed for each route and the model results were compared with the current condition. The results showed that using Mercedes buses was more economically efficient than using the other types, Volvo and Daewoo. Compared with the existing situation, the number of cycles as well as the number of buses should be increased to satisfy the average daily demand. The overall annual profit for the routes was proportional to their high daily demand except for one route. Even though, the model in this project can be extended to cover more paths and divide the day into shifts, which may lead to a better solution. Further studies are highly recommended to improve the public transport system in Kuwait.
