We present an algorithm for solving the Weber problem when the set of feasible locations is the union of a finite number of convex polygons.

This article analyses the bank regulation process in Denmark until the passing of the second Bank Act of 1930. It is demonstrated that the regulatory initiatives were the results of banking crises and that the explicit rationale for regulation was an attempt to avoid future banking crises i.e....

A major problem in foundries is to select scrap alloys and pure metals in order to produce at minimum cost alloy of specified composition. We show that such problems, of realistic size, can be solved optimally by mixed-integer programming. Constraints are that the content of the alloys in...
