    In our rapidly changing economy, businesses face the challenges of increasing their responsiveness and resiliency to varying market forces while minimizing business costs. Decisions that involve these challenges may catapult a business to success in the marketplace or cause a business to fail. Many examples exist of even a single poor business decision having a devastating impact on a business. Na... View full abstract»

    The IBM Research Division has developed the Resource Capacity Planning (RCP) Optimizer to support the Workforce Management Initiative (WMI) of IBM. RCP applies supply chain management techniques to the problem of planning the needs of IBM for skilled labor in order to satisfy service engagements, such as consulting, application development, or customer support. This paper describes two RCP models ... View full abstract»

    Matching highly skilled people to available positions is a high-stakes task that requires careful consideration by experienced resource managers. A wrong decision may result in significant loss of value due to understaffing, underqualification or overqualification of assigned personnel, and high turnover of poorly matched workers. While the importance of quality matching is clear, dealing with poo... View full abstract»

    In order to successfully deliver a labor-based professional service, the right people with the right skills must be available to deliver the service when it is needed. Meeting this objective requires a systematic, repeatable approach for determining the staffing requirements that enable informed staffing management decisions. We present a methodology developed for the Global Business Services (GBS... View full abstract»

    The changing nature of regulation forces businesses to continuously reevaluate the measures taken to comply with regulatory requirements. To prepare for compliance audits, businesses must also implement an effective internal inspection policy that identifies and rectifies instances of noncompliance. In this paper, we propose an approach to compliance management based on a quantitative risk-based o... View full abstract»

    In this paper we present a method for drawing inferences about the process of financial losses that are associated with the operations of a business. For example, for a bank such losses may be related to erroneous transactions, human error, fraud, lawsuits, or power outages. Information about the frequency and magnitude of losses is obtained through the search of a number of sources, such as print... View full abstract»

    We present our solution to the crew-scheduling problem for North American railroads. (Crew scheduling in North America is very different from scheduling in Europe, where it has been well studied.) The crew-scheduling problem is to assign operators to scheduled trains over a time horizon at minimal cost while honoring operational and contractual requirements. Currently, decisions related to crew ar... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (343 KB)

    We describe an optimization tool for a multistage production process for rectangular steel plates. The problem we solve yields a production design (or plan) for rectangular plate products in a steel plant, i.e., a detailed list of operational steps and intermediate products on the way to producing steel plates. We decompose this problem into subproblems that correspond to the production stages, wh... View full abstract»

    A major challenge in the initial stage of production planning for the steel industry is the material allocation problem (MAP): finding the best match of orders and materials (steel slabs and coils) with respect to an objective function that takes into account order due dates, preferences for matches, allocated weights, surplus weights of materials, and other factors. The MAP is NP-hard and is diff... View full abstract»

    As part of the prototyping effort for the preparedness module (PM) of the Fire Program Analysis (FPA) system that IBM developed for five U.S. federal agencies, we designed and implemented an optimization model for determining budgets necessary for managing wildland fires during the initial response period. For a given budget, the model uses a mixed-integer linear optimization approach to maximize ... View full abstract»

    This paper describes a prototype inventory-placement and transportation-scheduling solution developed in support of the emerging military doctrine of Network-Centric Operations (NCO). NCO refers to an unprecedented ability to share information among cooperating forces, enabled by modern communications and computing technology. The objective of the Network-Centric concept is to collect, disseminate... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (261 KB)

    We present an algorithm for performing multi-channel marketing event optimization. Previous related work, which made use of a complex mixed-integer linear program to generate a marketing plan, was capable of providing plans for only groups of individuals, referred to as micro-segments, and considered only the direct mail channel. Today, most firms use multiple channels, such as e-mail, call center... View full abstract»

    Many companies have no reliable way to determine whether their marketing money has been spent effectively, and their return on investment is often not evaluated in a systematic manner. Thus, a compelling need exists for computational tools that help companies to optimize their marketing strategies. For this purpose, we have developed computational models of customer buying behavior in order to det... View full abstract»

    We introduce a simulation optimization approach that is effective in guiding the search for optimal values of input parameters to a simulation model. Our proposed approach, which includes enhanced data mining methodology and state-of-the-art optimization technology, is applicable to settings in which a large amount of data must be analyzed in order to discover relevant relationships. Our approach ... View full abstract»

    We examine various aspects of modeling and solution via mixed-integer nonlinear programming (MINLP). MINLP has much to offer as a powerful modeling paradigm. Recently, significant advances have been made in MINLP solution software. To fully realize the power of MINLP to solve complex business optimization problems, we need to develop knowledge and expertise concerning MINLP modeling and solution m... View full abstract»
