This book addresses the solution of real life or industrial production planning problems (involving complex production structures with multiple production stages) using a MIP modeling and reformulation approach. It is based on close to twenty years worth of research in which the authors have played a significant role. One of the goals of this book is to allow non-expert readers, students in business, engineering, applied mathematics and computer science to solve such problems using standard modeling tools and MIP software. To achieve this the book provides a unique collection of reformulation results, integrating them into a comprehensive modeling and solution approach, as well as an easy to use problem-solving library. Moreover this approach is demonstrated through a series of real life case studies, exercises and detailed illustrations."--Jacket+-+440447238550314ocn184986501file20070.76Van Hentenryck, PascalIntegration of AI and OR techniques in constraint programming for combinatorial optimization problems 4th international conference, CPAIOR 2007, Brussels, Belgium, May 23-26, 2007 : proceedingsConference proceedingsAnnotation+-+K14872590840113ocn038976179book19980.73Wolsey, Laurence AInteger programming"Integer Programming stands out from other textbooks by explaining in clear and simple terms how to construct custom-made algorithms or use existing commercial software to obtain optimal or near-optimal solutions for a variety of real-world problems such as airline timetables, production line schedules, or electricity production on a regional or national scale."

Gomory transformed the field of integer programming when he published a paper that described a cutting-plane algorithm for pure integer programs and announced that the method could be refined to give a finite algorithm for integer programming. In 2008, to commemorate the anniversary of this seminal paper, a special workshop celebrating fifty years of integer programming was held in Aussois, France, as part of the 12th Combinatorial Optimization Workshop. It contains reprints of key historical articles and written versions of survey lectures on six of the hottest topics in the72ocn039229470book19770.47Lockett, A. GeoffreyA stochastic programming model for project selection62ocn009831793book19690.97Wolsey, Laurence AMixed integer programming: discretization and the group theoretic approachA new approach to the solution of mixed integer programming problems is developed, largely an extension of the group theoretic methods now being applied to all-integer problems. Discretization is used to replace any mixed integer programming problem by an equivalent integer programming problem. This permits the group theoretic approach of Gomory to be applied to such problems, resulting in a new 'asympototic' classification of mixed integer problems into three types which somewhat reflect degrees of difficulty. Given this classification, new solution methods for certain problems within these classes are developed, based mainly on the concepts of basis search and relaxation. It is also shown how mixed integer problems in which the number of constraints exceeds the number of continuous variables, and a variety of special problems, such as the plant location problem, can be very simply replaced by integer problems. This makes possible the direct solution of these problems by the existing group theoretic integer programming algorithms.
