Over the past two decades, maritime transportation and container traffic worldwide has experienced rapid and continuous growth. With the increase in maritime transportation volume, the issue of greenhouse gas (GHG) emission has become one of the new concerns for port managers. Port managers and government agencies for sustainable development of maritime transportation considered "green ports" t...

failure of the quay walls due to earthquakes results in severe economic loss. because of hazards threatening such inexpensive nodes of national and international transportation networks, seismic design of quay walls is still an evolving topic in marine structural engineering. this study investigates the sensitivity of the gravity-type quay wall stability respect to uncertain soil and seismic pr...

The factory crane scheduling problem (FCSP) deals with assigning delivery tasks to cranes and then sequencing them, in order to minimize the total completion time for all tasks. In this paper, delivery tasks for required jobs are preemptive allowed at most once before the jobs arrive at exit. The preemptive jobs are temporarily stored in a buffer stack, in which jobs pickup and delivery should ...

Abstract To enable the efficient division of labor in container yards, many large ports apply twin cranes, two identical automated stacking cranes each dedicated to one transfer zones on seaside and landside. The use a handshake area, bay containers that separates areas is simple means avoid crane interference. Inbound arriving zone position other crane’s area are placed intermediately by first...

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 ...

In this paper, we present a new topic in connection with project scheduling. Since a limited work space can form a restriction to project scheduling problems, an efficient usage of these work spaces (or so-called spatial resources) is required to produce good project schedules. The requirement for the resource units of these spatial resources is in an adjacent manner (we cannot place a product ...
