The Capacitated Facility Location Problem (CFLP) is a well-known combinatorial optimization problem with applications in distribution and production planning. A variety of lower bounds based on Lagrangean relaxation and subgradient optimization has been proposed for this problem. However, in...

Assignment type problems consist in optimally assigning or allocating a given set of "activities" to a given set of "resources". Optimisation problems of the assignment type have numerous applications in production planning and logistics. A popular approach to solve such problems or to compute...

The design of the distribution system is a Strategie issue for almost every Company. The Problem of locating facilities and allocating customers Covers the core topics of distribution system design. Model formulations and Solution algorithms which address the issue vary widely in terms of...
