چکیده

Since the premium prices of yard trucks and significantly daily volatility of containers serving demand, it is an uneconomic method to keep a full team of fleet to cover the entire service. Some of the transportation services are outsourced to other external companies. The strategy of outsourcing yard trucks is a decision making problem that container terminals are currently facing. Yard truck scheduling and storage allocation are two major operations that related to yard trucks management problem. In this paper, the studied yard trucks management problem is focused on integration of the yard truck scheduling and the storage allocation problems. The objective is to minimize the total operation cost of in-house trucks, out-sourced trucks, and delay of requests. As the proposed problem is an NP-hard problem, a hybrid heuristic approach with genetic algorithm and linear programming is proposed to solve the problem. The effectiveness of the proposed method is analyzed from using practical data obtained from Hong Kong terminals.

Quay Cranes and Yard Trucks Scheduling Problem at Container Terminals

A bi-objective mathematical model is developed to simultaneously consider the quay crane and yard truck scheduling problems at container terminals. Main real-world assumptions, such as quay cranes with non-crossing constraints, quay cranes’ safety margins and precedence constraints are considered in this model. This integrated approach leads to better efficiency and productivity at container te...
