The optimal number of yard cranes in container terminal

The aim of this study is to propose a new mixed integer linear programming (MILP) model to find the minimum required number of yard cranes, Ruhher tyred gantry cranes (RTGCs), for completion the total amount of works at the end of planning horizon. In other word, we find the optimal number of yard cranes in a container terminal which completes the total amount of works. The paper supports the proposed method using a numerical example.
