In spite of the remarkable improvements in the quality of general purpose mixed integer programming software, the effective solution of a variety of lot-sizing problems depends crucially on the development of tight formulations for the special problem features occurring in practice. After...

BC-PROD is a prototype modelling and optimization system designed and able to tackle a wide variety of the discrete-time lot-sizing problems arising both in practice and in the literature. To use BC-PROD, the user needs to formulate his/her problem as a mixed integer program using XPRESS-MP's...

We study further a problem that has arisen recently in the design of telecommunications transmission networks at France Telecom. Given a set of centers in a city of conglomeration linked together on a ring architecture, given the expected demands between the centers and an essentially unlimited...
