SOLVING CONSTRAINED TWO-FACILITY LOCATION PROBLEMS(<Special Issue>ISOLDE XII)

Abstract

A general approach to optimally solve multiple facility location problems based on the "Big Triangle Small Triangle" approach to solving single facility problems is proposed. The proposed procedure is especially effective when the solution is constrained to a given polygon such as the convex hull of demand points. The procedure is tested on the two facilities Weber problem with attraction and repulsion (WAR) with excellent computational results.
