This paper presents the analysis of the optimal production and corrective maintenance planning problem for a failure prone manufacturing system consisting o...

This study investigates a new phenomenon of degeneracy in the multi-source Weber problem. This phenomenon relates to the existence of solutions in which one...

We present a new convergence result for the cone partitioning algorithm with a pure <img src="omega.gif" align=bottom>-subdivision strategy, for the minimiz...

An algorithm based upon the boundary-edges code and the reverse search method is proposed for enumerating non-isomorphic planar simply connected polyhexes. ...

Systematic change of neighborhood within a possibly randomized local search algorithm yields a simple and effective metaheuristic for combinatorial and glo...

This paper addresses the problem of generating valid crew pairings in the context of a regional air carrier. The classical column generation solution appro...

The locomotive assignment problem is to provide at minimum cost sufficient motive power to pull all the trains of a time tabled schedule. Optimization metho...

This paper deals with the inventory-production control problem where the produced items are supposed to be deteriorating with a rate that depends on the sto...

Chopping a graph <i>G</i> means removing one edge from each connected component of <i>G</i> in parallel, and repeating this until no edges remain. The requi...

We present a 0-1 column generation model for channel block assignment in a cellular network, with the objective of minimizing the interference level. Priori...

The Steiner Tree Problem in graphs (STP) is well known NP-Hard problem. It has regained attention due to the introduction of new telecommunication technolog...

In recent years, several advances have been made towards the solution of stochastic vehicle routing problems (SVRPs). In particular, the Integer <i>L</i>-Sh...

This article describes a heuristic and two exact algorithms for several classes of vehicle routing problems defined on tree networks. These include capacita...

We study the subgradient projection method for convex optimization with Brännlund's level control for estimating the optimal value. We establish global con...

A new hybrid algorithm is being introduced for solving Mixed Integer Nonlinear Programming (MINLP) problems which arise from study of many real-life enginee...

This article describes a method for solving the crew rostering problem in air transportation. This problem consists of constructing personalized schedules ...

This paper deals with the problem of how to update a telecommunication network economically. We first propose a mixed integer programming model that include...
