Abstract: In order to assist port operators in planning yard trucks (YT) routing and scheduling problems efficiently and decrease the pollution of yard trucks operation, this research utilizes the time-space network technique to describe the potential movements of yard trucks among all quay cranes (QC) and yard cranes (YC) in the time and space dimensions. The objective function is to minimize the total cost of operating and emission costs which considering the queuing theory with M/M/S model. The optimized number of yard trucks and its routing and scheduling can be solved by the developed model simultaneously. Since the model can be formulated as a multi-commodity network flow problem, which is characterized as NP-hard, a heuristic algorithm is proposed to efficiently solve the model. The model and algorithm can be used to evaluate a problem instance generated from the real data provided by an international port, and the analysis result could be useful references for port operators in actual practice. In this study, an experimental design of the small QC and YC operation network is considered with the import containers by YT. A preliminary result has approved that the optimized solutions can be solved by the developed model and it can be further applied to the practical operations.
