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 ...

Since the premium prices of yard trucks and significantly daily volatility of containers serving demand, it is an uneconomic method to keep a full team of fleet to cover the entire service. Some of the transportation services are outsourced to other external companies. The strategy of outsourcing yard trucks is a decision making problem that container terminals are currently facing. Yard truck ...

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...

When transporting goods, truck drivers may have to perform load transfers between two vehicles at cross-dock or transfer locations. These create interdependencies the routes of different and require careful temporal synchronization. The situation becomes even more complicated when driver schedules must comply with customer time windows, working periods regulatory resting requirements. Although ...

In this paper, based on the Position Maintaining Strategy (PMS for short), on-line scheduling of k-truck problem, which is a generalization of the famous k-server problem, is originally presented by our team. We proposed several competitive algorithms applicable under different conditions for solving the on-line k-truck problem. First, a competitive algorithm with competitive ratio 2k + 1/θ is ...
