摘要：	Physical distribution plays an important role in the shipping industry. Considering transportation costs amount for a fifth or even a quarter of the average sales dollars, the delivery of goods from a depot to local customers is an important and practical problem for logistics managers. In reality, we are facing the fluctuation of demand. When the total demand is greater than the whole capacity of owned trucks, logistics managers may consider adopting a multi-trip strategy or using an outsider carrier. In this study, logistics managers must route a fixed number of trucks with different capacities from a single depot to customers with certain demand while trucks can operate multi trips with time window constraints or logistics managers make a selection of less-than-truckload carriers. The main objective of this study is to develop mathematical model to help logistics managers solving the problem. The results show that the proposed integer programming model can provide more flexible vehicle scheduling for logistics managers, lower operating costs and increase profits for a company.
