Storage location assignment and interleaving policy are two closely related problems in warehousing management. This paper addresses the location assignmen...
BibTeX referenceConvexity and Concavity Detection in Computational Graphs. Tree Walks for Convexity Proving
In this paper, we examine sets of tools associated to modeling systems for mathematical programming which can be used to automatically detect the presence ...

This paper describes a Parallel Space Decomposition (PSD) technique for the Mesh Adaptive Direct Search (MADS) algorithm. MADS extends Generalized Pattern ...
BibTeX referencePath Reduced Costs for Eliminating Arcs
In many branch-and-price algorithms, the column generation pricing problem consists of computing feasible paths in a network. In this paper, we show how, in...

When constructing a metro alignment under a historical city centre, it is important to generate a cost effective path while maintaining a minimum distance be...
BibTeX referenceCould Myopic Pricing be a Strategic Choice in Marketing Channels? A Game Theoretic Analysis
We identify the conditions under which a myopic pricing behavior could be a profit enhancing tool in the distribution channel. A channel member behaves myo...

Given a fleet of vehicles assigned to a single depot, the vehicle routing problem with time windows (VRPTW) consists of determining a set of feasible v...
