Motivated by the significant influence of trade allowance on store operation and the efficiency of shelf-space allocation, this article develops a model for optimizing category-level shelf-space management. A category shelf-space allocation framework

Managing shelf space is critical for retailers to attract customers and optimize profits. This article develops a shelf-space allocation optimization model that explicitly incorporates essential in-store costs and considers space- and cross-elasticit

Shelf management is a crucial task in retailing. Because of the large number of products found in most retail stores (sometimes more than 60 000), current shelf space management models can only solve sub-problems of the overall store optimization pro

This paper formulates a model for finding a minimum cost routing in a network for a heterogeneous fleet of ships engaged in pickup and delivery of several liquid bulk products. The problem is frequently encountered by maritime chemical transport comp

This paper presents two linear cutting plane algorithms that refine existing methods for solving disjoint bilinear programs. The main idea is to avoid constructing (expensive) disjunctive facial cuts and to accelerate convergence through a tighter bo

We consider probabilistically constrained linear programs with general distributions for the uncertain parameters. These problems involve non-convex feasible sets. We develop a branch-and-bound algorithm that searches for a global optimal solution to

A problem arising in the control of flutter in compression systems via mistuning is formulated as maximizing a quadratic function with a circulant matrix over a set of vectors whose every component can take one of three values (the three level proble

Recently, we proposed a d.c. (difference of convex) optimization method for finding global solutions to single facility location problems having general attraction and repulsion functions. The method, which is based on a representation of the nonconv

In this paper, we develop a decomposition technique for the solution of a two-stage decision and scheduling problem in production environments. A tree search heuristic based on the decomposition approach is developed. We illustrate the procedure on t

Many production environments such as carpet or flat glass manufacturing have linked operations that perform completely different activities. In this paper, we consider a two-stage manufacturing process involving a cutting operation, followed by an as
