Article
Full-text available
Worldwide declines in fishery yields emphasize the need for innovations in fishery management methods and models that encompass the complex dynamics of fish stocks and a broader range of human impacts. To this end, we have developed a generalized analytical framework that builds upon and extends principles of traditional fishery management by utili...
Article
Researchers in several business disciplines have convincingly argued that environmentally responsible strategies can contribute to competitive advantage and superior financial performance. While debates on ecological conservation and environmental practices within marketing have raged for over three decades, much of the focus has been on identifyin...
Article
We study the problem of suitably locating US Coast Guard air stations to respond to emergency distress calls. Our goal is to identify robust locations in the presence of uncertainty in distress call locations. Our analysis differs from the literature primarily in the way we model this uncertainty. In our optimization and simulation based methodolog...
Article
Driven by market pressures for greater variety of services at lower costs, financial service firms are increasingly partnering with independent vendors to create service networks that deliver high quality services at low costs and generate greater revenues. The outsourcing trend is especially pronounced in the management of call center networks, wh...
Article
Full-text available
Issues in evaluating marketing performance and devising appropriate metrics for measurement have taken center stage in marketing thought and practice in recent years. We propose an empirical model that enables a multinational enterprise (MNE) to assess the marketing performance of its subsidiaries, taking into explicit consideration the fact that t...
Article
The IMPASSE class of local search algorithms have given good results on many vertex colouring benchmarks. Previous work enhanced IMPASSE by adding the constraint programming technique of forward checking, in order to prune colouration neighbourhoods ...
Article
In the last two decades, particularly with the advent of the Internet, multichannel strategies have come to the fore in business-to-business marketing. Multichannel strategies allow firms to reach customers in multiple ways, increasing the firms' reach. In addition, multichannels allow customers to reach businesses by using their preferred channel...
Chapter
We present a branch-and-price framework for solving the graph multi-coloring problem. We propose column generation to implicitly optimize the linear programming relaxation of an independent set formulation (where there is one variable for each independent set in the graph) for graph multi-coloring. This approach, while requiring the solution of a d...
Article
Baseball teams face the problem of choosing a set of nine players to start in each game and of determining a sequence in which these nine players bat. The objective is typically to maximise the offensive capability of the team. In baseball, the payoffs associated with a slight statistical advantage can be huge. While these are difficult to quantify...

Article
Higher education administrators regularly make decisions regarding the allocation of multi‐million institutional dollars in attracting superior students, while trying to maximise certain factors such as net revenue, quality and enrolment. Often these decisions are made based on experience or some times in an ad hoc manner. The resulting enrolment m...
Article
We develop a heuristic procedure for partitioning graphs into clusters of nodes such that each cluster of nodes induces a connected subgraph with the objective of minimizing the differences within clusters as measured by the total differences between all pairs of nodes of a cluster. We apply our procedure to determine optimal delivery zones for com...
Article
Full-text available
Recent reports have raised serious concerns about the rapid declines of historically productive marine fishery resources and the degradation of essential fish habitats. This global crisis has spurred development of innovative management strategies to rebuild depleted fisheries and marine ecosystems. One highly touted strategy involves the design an...
Article
Community sections of newspapers are an increasingly important source of advertising revenue and readership for large city newspapers. Determining the optimal delivery zones for these sections is a complicated optimization problem needing to handle a number of operational issues. We develop an optimization based procedure to generate geographically...
Article
The inventory of spare parts that a firm holds depends on the number of working parts and age of the equipment to be serviced, the expected failure rate associated with each working part, and the acceptable level of service. We model the problem of consolidation of spare parts to reduce overall inventory as an integer program with a nonlinear objec...
Article
We present a branch-and-price technique for optimal staff scheduling with multiple rest breaks, meal break, and break windows. We devise and implement specialized branching rules suitable for solving the set covering type formulation implicitly, using column generation. Our methodology is more widely applicable and computationally superior to the a...
Article
The last decade has fundamentally changed the face of retailing. The genesis has been increased customer fragmentation, enabling technologies such as the internet and increased competition. In this era of “hypercompetition,” retailers need to have a better understanding of the performance of individual stores so they can more accurately plan their...
Article
Full-text available
Redistricting, the redrawing of congressional district boundaries within the states, may occur every 10 years on the basis of the population census. Many redistricting plans are designed with partisan politics in mind, resulting in disputes and forcing judges to intervene. We address this problem from a nonpolitical viewpoint and present an optimiz...
Article
Full-text available
We use column generation and a specialized branching technique for solving constrained clustering problems. We also develop and implement an innovative combinatorial method for solving the pricing subproblems. Computational experiments comparing the resulting branch-and-price method to competing methodologies in the literature are presented and sug...
Article
Full-text available
We study the polyhedral structure of an integer programming formulation of the cardinality constrained Boolean quadratic problem. We give many facet-defining inequalities. The separation problems for these inequalities appear to be difficult, which explains, in part, the difficulty encountered in solving these problems via a branch-and-cut methodol...
Article
We present a method for solving the independent set formulation of the graph coloring problem (where there is one variable for each independent set in the graph). We use a column generation method for implicit optimization of the linear program at each node of the branch-and-bound tree. This approach, while requiring the solution of a difficult sub...
Article
We describe a decomposition framework and a column generation scheme for solving a min-cut clustering problem. The subproblem to generate additional columns is itself an NP-hard mixed integer programming problem. We discuss strong valid inequalities for the subproblem and describe some efficient solution strategies. Computational results on compile...
