As we mentioned, the main functions of container terminals are delivering containers to consignees and receiving containers from shippers, loading containers onto and unloading containers from vessels and storing containers temporarily. A complete economic plan has to identify and represent the fundamental components in a container terminal and transportation system. These components are demand, supply, cost, performance measures, and decision criteria. Their interactions may be considered. Developing a demand function to receiving containers from shippers, developing a supply model to delivering containers to consignees, estimating a cost function for the vehicles, Quay Cranes, Yard Cranes, and even container terminal are in the list for the future. The research may estimate the weights of traveling and waiting times of the vehicles, the weights of holding cost of jobs on the quayside or in the yardside with particular assumptions. A performance function based on some economic indicators may be maximized. Constraints of the function are the spatial allocation of containers in the terminal yard, the allocation of resources and the scheduling of operations.

It was found that by implementing the empty container reuse idea a substantial reduction in the empty related truck trips to and from the container ports as well as in the empty container moving related costs can be obtained. Moreover, by allowing substitution between different types of empty containers, we can further reduce the number of the truck trips and decrease the empty related costs. This indicates that by implementing the empty container reuse idea the traffic congestion around the container terminals can be improved, and as a consequence, noise and emissions can be reduced significantly.

Container terminal operations mainly include berth allocation and quay crane assignment, yard allocation and planning, horizontal transport scheduling, gate system management and so on (Stahlbock and Voß 2008). A wide range of optimization models have been developed in the literature and have been tested and implemented in improving container terminal operations and management. Bierwirth and Meisel (2010, 2015) provided a detailed survey of berth allocation and quay crane scheduling problems for the purpose of operating container terminals in an efficient manner. Yard operations were widely investigated in either deterministic or uncertain environment (Zhen 2014, 2016; Lin and Chiang 2017) or together with berth allocation (Zeng, Feng, and Chen 2017; Tao and Lee 2015). Carlo, Vis, and Roodbergen (2014) presented an in-depth overview of transport operations at container terminals and highlighted trends and latest development of relevant issues. In fact, each part of a container terminal is not independent of the others and they usually interact with each other. Accordingly, it is necessary to construct an integrated framework to capture the interactive behavior of these components or facilities at a container terminal.
Carbon-efficient scheduling problem of electric rubber-tyred gantry cranes in a container terminal

A partial view of a typical container terminal is shown in Figure 1. At the seaside area of container terminals, containers are loaded on or unloaded from vessels by quay cranes and transported between vessels and the yard by internal trucks. At the landside area, external trucks transport containers into and out of the yard. The container yard is a decoupling point between the seaside and landside operations where the containers are temporarily stored until they are picked up by internal or external trucks (Kemme 2012). Therefore, the high efficiency of yard operations is critical to guaranteeing the efficiency of the entire container terminal.
