Abstract: On the base of the fundamental model whose objective was to minimize the company’s costs，multiple depot dispatching problem was discussed and then the corresponding model was established，in which minimizing passengers’waiting expense was considered in the objective function. Then deficit function was used to solve the objective function，which can be solved in two different ways: firstly，manual work was used to insert the deadheading trips to restrict the passengers’ waiting time; secondly，PT-manager simulation software which was built on the base of deficit function was introduced to simulate and analyze. In order to make a statistic explore the actual data was introduced. The results proved that the using deficit function to solve the proposed model is simple and accurate. PT-manager simulation software could provide guide and optimization for bus dispatching staff，which also could provide referential significance to the current bus dispatching and the development of multiple depot dispatching.
