where A is a matrix of order m × p and rank m, and A is a real valued parameter. It may be required to solve this problem for all real values of A, or for all values of A in some specified interval of the real line. f(A) is a piecewise linear convex function in A. The simplex algorithm for this parametric linear program partitions the real line into(More)
We describe a variety of inter-related 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)
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)
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 present a version of the gravitational method for linear programming, based on steepest descent gravitational directions. Finding the direction involves a special small “nearest point problem” that we solve using an efficient geometric approach. The method requires no expensive initialization, and operates only with a small subset of locally active(More)
