Bicriteria network location (BNL) problems with criteria dependent lengths and minisum objectives
We present a new location model, which is a generalization of the bicritera median problem. We introduce two sum objectives and criteria dependent edge lengths. For this complete problem a solution method finding all the efficient solutions is presented. The method is a two-phases approach, which can easily be applied as an interactive method. In Phase 1 the supported solutions are found, and in Phase 2 the unsupported solutions are found. This method can be thought of as a general approach to bi-objective combinatorial optimization (BOCO) problems.
