Container terminals are essential intermodal interfaces in the global transportation network. Efficient container handling at terminals is important in reducing transportation costs and keeping shipping schedules. In this paper, we study the storage space allocation problem in the storage yards of terminals. This problem is related to all the resources in… (More)
We establish that in the worst case, the computational effort required for solving a parametric linear program is not bounded above by a polynomial in the size of the problem.
We describe a variety of interrelated decisions made during daily operations at a container terminal. The ultimate goal of these decisions is to minimize the berthing time of vessels, the resources needed for handling the workload, the waiting time of customer trucks, and the congestion on the roads and at the storage blocks and docks inside the terminal;… (More)
We discuss infeasibility analysis (study of changes needed to make an infeasible system feasible) for systems of linear constraints.
As more and more container terminals open up all over the world, competition for business is becoming very intense for container terminal operators. They are finding out that even to keep their existing Sea Line customers, they have to make them happy by offering higher quality service. The quality of service they can provide depends on their operating… (More)
One of the motivating factors behind the development of the theories of probability and statistics is to obtain good forecasts for future values of random variables that appear in many applications. Managers in industry and business depend heavily on good forecasts of product demand. History shows many examples of Þrms beneÞting from accurate forecasts and… (More)
In  a new interior point method has been developed for linear programming (LP), based on a new centering strategy that moves any interior feasible solution x 0 to the center of the intersection of the feasible region with the objective hyperplane through x 0 , before beginning the descent moves. Using this centering strategy, that method obtains an… (More)
