This paper presents a very large scale neighborhood (VLSN) search algorithm for the capacitated facility location problem with single-source constraints. The neigh- borhood structures are induced by customer multi-exchanges and by facility moves. We consider both single-customer multi-exchanges,...

Planning to mitigate the impacts of a disaster can be an important activity for both private companies and public agencies. In this paper we consider a supply system that provides needed goods or services to a region that may be the subject of some type of disaster, such as an attack by a...

We present a very large-scale neighborhood (VLSN) search algorithm for the capacitated facility location problem with single-source constraints. The neighborhood structures are induced by customer multi-exchanges and by facility moves. We consider both traditional single-customer...

This paper addresses the problem of estimating or updating a passenger trip matrix for transit networks from passenger courts. An extension of a model to take into account time information contained in the passenger counts is developed. Several promising optimization formulations of the...
