Modelling the Container Yard as an Operational System in a Port: A Methodological Approach

The paper presents M^X / M / c batch queues in which the group size is given by the shifted-Poisson and Poisson-like distributions. This queue model deduced the expressions for the specific cost ratio involving the state probabilities, the utilization factor, the mean and the variance of the group size. Proposed model discusses the total queuing system costs of container at container yard (CY) and specific cost ratio to improve the best values for container performances at CY. The analytical approach make the model appropriate to analyze. The special cases can be solved exactly, which is shown in another paper dealing with the application of this methodological approach.
