1.Introduction
Handling is one of the important subsystems of logistics system, which is accompanied by logistics activities like transportation and storage, is the intermediate link of transportation, storage, package, circulation processing and distribution, and it is inseparable from any logistic activities. Therefore, handling as an indispensable important link of the whole logistics process, its importance is not allowed to ignore. Improving handling system can significantly improve logistics economic and social benefits, and for how to improve efficiency, reduce the cost of handling, it’s
necessary to use the queuing theory to establish handling queuing model, to construct the optimization of handling service system. A large number of application research shows that queuing theory is one of the effective methods to find the most economic system operation cost, to solve the optimization of system operation parameter. The queuing phenomenon is widely existed in the field of logistics handling, such as how to design the pier berth, how to purchase the handling equipment and etc, and how to not only satisfy the arrival in timely service demand but also design the best configuration scheme for pier berth, handling equipment and service resources under the condition of
saving port resources. So applying queuing theory and method to solve the optimization of port handling service system is of important theoretical and practical significance.
