Container transport, an integral part of intercontinental trade, has steadily increased over the past few decades. The productivity of such a system, in part, hinges on the efficient allocation of terminal resources such that the container transit time is minimized. This study provides an analytical framework, which entails efficient scheduling of quay and yard cranes, to minimize the time spen...

In response to the phenomenon that some container terminals are excess capacity and some others are overloaded because of the imbalance of transportation development, this paper proposed a 3D simulation model of operation system for the container terminal apron. First, we study the characteristics of operation system for container terminal apron. Second, a 3D simulation model of terminal apron ...

At container terminals, quay cranes, yard trucks, and cranes are mainly used to transfer containers. Driven by the demand for a green low-carbon economy, an integrated scheduling problem considering three types of handling equipment systems is studied. As task transferring each completed sequentially, optimal solution may not be found only studying one type separately from operations perspectiv...

With the rapid growth of global container trade volume and trend large-scale ships. The collection distribution port efficiency capacity terminals in various countries are facing huge challenges. Due to randomness most trucks entering port, often face problem traffic congestion caused by centralized arrival load operation yard equipment. Therefore, terminal operators urgently need manage optimi...

In this paper we present a discrete event simulation model to approach the decision problems arising from an expansion plan of a marine container terminal. In particular the preliminary study herein presented starts from a collaboration with the Southern European Container Hub (SECH) sited in the Port of Genoa, Italy. The planned expansion will take place from 2010, the terminal area will enlar...

The population growth of endangered whooping cranes (Grus americana) is not consistent with species recovery goals, and the impact of parasite infection on whooping crane populations is largely unknown. Disease ecology and epidemiology research of endangered species is often hindered by limited ability to conduct invasive sampling on the target taxa. Accordingly, we hypothesized that sandhill c...

In yard-crane scheduling problems, as loading operations take priority over unloading, the delivery sequence of unloading from quaysides to yard is uncertain. The changes may make crane more difficult. As a result, schedules developed statically become suboptimal or even infeasible. this paper, we propose dynamic problem considering uncertain sequences. A mixed-integer linear program assign tas...

We analyzed the gizzards, and grits retained in the gizzards of 41 24 cranes that migrated to the Izumi Plain during the winter of 2015/2016 and died 25 there, either due to accident or disease. These included 31 Hooded Cranes (Grus 26 monacha) and 10 White-naped Cranes (G. vipio). We determined body weight, 27 gizzard weight, total grit weight and number per gizzard, and size, shape, and 28 su...
