Committed to converting the Port of Balboa into a major transshipment hub, Panama Ports Company (PPC) launched in 2006 a $300-million expansion program to increase berthing and stacking space that would almost triple the port capacity. The site’s history of marine-related activities, deteriorating facilities, buried structures, and poor soils mandated significant investment in clearing and prep...

Motivated by the field sta routing and scheduling problem of an Austrian infrastructure service provider, which involves the planning of subroutes, we study the truck and trailer routing problem (TTRP) [2]. In the TTRP, two types of customers are considered: customers that can be visited by a truck pulling a trailer (denoted as vehicle customers) and customers that can only be visited by a truc...

Nowadays, one of the major goals of the distribution environment is to reduce lead times and inventories. Cross-docking is a logistics technique which removes the storage and picking up the functions of a warehouse. The term cross-docking refers to moving products directly from incoming to outgoing trailers with little or no storage in between. According to the recent related papers, the truck ...

the dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

the problem of staff scheduling at a truck hub for loading and stripping of the trucks is an important and difficult problem to optimize the labor efficiency and cost. the trucks enter the hub at different hours a day, in different known time schedules and operating hours. in this paper, we propose a goal programming to maximize the labor efficiency via minimizing the allocation cost. the propo...

Aim of this study was investigating a truck scheduling problem with uncertainty in both inbound and outbound problems. Scheduling authorities at cross-dock should consider these uncertainties and propose a scheduling & sequencing plan which is robust against these uncertainties. As we know, trucks don’t necessarily assign to receiving or shipping doors and should wait a while till a proper dock...

The full-truck-load route planning and scheduling with time appointment system falls in the class of Traveling Salesman Problem with Time Windows (TSPTW). In this paper, methods for improving the scheduling of intermodal trucks in deterministic and stochastic environments, where ISO containers need to be transferred between marine terminals, intermodal facilities, and end customers are investig...
