We study the p-median problem which is one the classical problems in location theory. For p = 2 and on a two-dimensional mesh, we give an O(mn 2 p)-time algorithm for solving the problem, where, assuming that m n, m is the number of rows of the mesh containing demand points, n the number of columns containing demand points, and p the number of demand points.

Abstract. The theoretical problems of demand-side management are examined in without regard to the type of resource whose demand is to be managed, and the Maximum Demand problem is identified and addressed in a system consisting of independent processes that consume the resource. It is shown that the Maximum Demand problem generalizes the Santa Fe Bar Problem of game theory, and the basic prope...

The current study examines similarity or disparity of a frontally mediated physiological response of mental effort among multiple executive functioning tasks between children and adults. Task performance and phasic heart rate variability (HRV) were recorded in children (6 to 10 years old) and adults in an examination of age differences in executive functioning skills during periods of increased...

When solving location problems in practice it is quite common to aggregate demand points into centroids. Solving a location problem with aggregated demand data is computationally easier, but the aggregation process introduces error. We develop theory and algorithms for certain types of centroid aggregations for rectilinear 1-median problems. The objective is to construct an aggregation that min...

Solving combinatorial problems is increasingly crucial in business applications, in order to cope with hard problems of practical relevance. However, the approach of exploiting, in production scenarios, current constraint or mathematical programming solvers has severe limitations, which demand new methods: data is usually stored in potentially large relational databases, and maintaining the pro...

This paper deals with the Hitchcock transportation problem with m supply points and n demand points. Assume that m ~ n and all the data are positive integers which are less than or equal to an integer M. We propose two polynomial time algorithms for solving the problems. The algorithms are based on the interior point algorithms for solving general linear programming problems. Using some feature...

A single source transportation problem is an ordinary transportation problem with the additional requirement that the entire demand at each demand location be supplied from a single supply location. It is a special case of Ross and Soland's generalized assignment problem. Such problems occur frequently in applications. This paper gives two heuristic solution methods and a branch and bound algor...

Telemedicine promises to be one of several possible solutions to some of the medical dilemmas facing India and other developing countries. The use of communication technology in the practice of medicine may change the face of health care in India by improving access to dispersed expert medical information, diagnostic tools, and consultations. Increasing demand on practitioners’ time and the inc...
