Crane double cycling is a quay crane operation strategy that minimizes an empty trip of the equipment involved in the vessel operation. From the perspective of quay crane, a quay crane unloads a container onto a horizontal transport vehicle, such as yard tractor, automated guided vehicle or straddle carrier. From the perspective of the transport vehicle, a vehicle delivers a loading container to a quay crane and instead of directly returning to the storage yard for the next loading container, the vehicle accesses another quay crane which can deliver an unloading container to the vehicle itself. The quay crane double cycling problem is a special case of the well-known quay crane scheduling problem, the main aim is to find a complete quay crane working schedule with its objective typically being the minimization of the makespan for the vessel operation, the minimization of the total completion time of quay crane, or the combination of both. In this study, the problem is studied via simulation modeling, which is one of the powerful analysis tools available for the design and operation of complex processes or systems. The data of the problem (crane, rubber tired gantry cranes service operation times and etc.) are collected from The Container Loading & Unloading Services of Izmir Port. A discrete event simulation model is developed by using Arena software to model port operations. The objective of the model is to decide a quay crane operation strategy that minimizing an empty trip (Crane, RTG and Truck service operation time) of the equipment involved in the vessel operation.
