Capacity Analysis of Restricted Channels Based on the Queuing Theory

Channel capacity is an important factor in port operation and development planning.It is of theoretical and practical significance to scientifically and rationally decide the capacity of restricted channels.This paper decides the capacity of restricted channels with the queuing theory.The dynamic calculation of the degree of saturation of restricted channels is achieved through the dynamic features of queuing theory calculation.The method is applied to the main channel planning and design of the expansion project in Tianjin port.The results show that with the method the operational status of the channel is evaluated objectively,and prove the method feasible and reliable.
