p-median modelThis paper is concerned with machine cell/part family (MC/PF) formation in cellular manufacturing. Among the solution methodologies for MC/PF formation, the mathematical programming approach seeks to find the optimal number of machine cells and associated part families. The p-median ...
The p-median model for solving the logistics center location problem is established and the fast solution of the model is realized by using Greedy Dropping Heuristic Algorithm. Combined with specific cases, a kind of actual location problem is solved to verify the correctness of the model and ...
The p -median model is an especially well-studied clustering problem that requires the selection of p objects to serve as cluster centers. The objective is to choose the cluster centers such that the sum of the Euclidean distances (or some other dissimilarity measure) of objects assigned to ...

A cornerstone of such a model is the measure of distance between a service center and demand points, i.e. the location of the population (customers, pupils, patients, and so on). Evidence supports the current practice of using Euclidean distance. However, we find that the location of ...

We favour the gravity -median model, but we note that in an applied setting, Drezner and Drezner's arguments are incomplete. In this communication, we point at the existence of a fourth compelling argument for the gravity -median model. 展开 ...
