ON THE APPLICATION OF COMBINED MODELS: A CASE STUDY ON THE SIMULATION OF CONTAINER OPERATIONS
In this paper, performance of two different approaches to the simulation of service times, in situations in which service times are correlated, is analyzed. Loading and unloading of containers at marine intermodal terminals provided the case study. The first approach, that is referred to as combined model, expresses service times as a function of two components, systematic and random. The second approach relies on the use of empirical service time distributions to simulate service times by essentially assuming that service times are the outcomes of independent random variables. Results indicated that, overall, the combined model performed better than the empirical distribution. In addition, a significant advantage of the combined model is its ability to simulate situations different than the one used in its estimation.
