Download or read book Evaluation of a Shadow Price Search Heuristic as an Alternative to Linear Programming Or Binary Search for Timber Harvest Scheduling written by Peter Eldred (D.) and published by . This book was released on 1987 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The planning of harvests and management activities for forested lands has traditionally been done with either binary search or linear programming. Since both these techniques have some advantages over the other, they have remained in wide use. Hoganson and Rose (1984) have suggested a technique that theoretically could overcome some of the problems with binary search and linear programming while retaining many of their desirable characteristics. The technique uses shadow prices to guide the search for harvest levels in each period to meet certain goals. This study develops a new set of shadow price search procedures and makes a comparison between these three different harvest scheduling techniques. The comparisons were made by constructing a PASCAL computer model that gives the user a choice of solving harvest scheduling problems with either binary search or this new method, that will be referred to as "shadow price search". The computer program MIJSYC was used for the linear program formulations. Three example were solved by each of these methods. The results showed that linear programming and shadow price search produced solutions with similar harvest patterns among stands and present net worths that were close in value. Binary search found very different harvest patterns and consistently lower present net worths than either of the other two methods. Solution times for shadow price search were greater than binary search, but still less than linear programming solution times. Shadow price search seems a promising alternative to the traditional approaches for harvest scheduling problems with many timber stands and few constraints. For these problems, it's major drawback is occasional difficulty in converging on the optimal solution. Future research may solve this problem.

This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * at Purdue. University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Download or read book Optimization Modeling with Spreadsheets written by Kenneth R. Baker and published by John Wiley & Sons. This book was released on 2012-01-10 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reflects the latest applied research and features state-of-the-art software for building and solving spreadsheet optimization models Thoroughly updated to reflect the latest topical and technical advances in the field, Optimization Modeling with Spreadsheets, Second Edition continues to focus on solving real-world optimization problems through the creation of mathematical models and the use of spreadsheets to represent and analyze those models. Developed and extensively classroom-tested by the author, the book features a systematic approach that equips readers with the skills to apply optimization tools effectively without the need to rely on specialized algorithms. This new edition uses the powerful software package Risk Solver Platform (RSP) for optimization, including its Evolutionary Solver, which employs many recently developed ideas for heuristic programming. The author provides expanded coverage of integer programming and discusses linear and nonlinear programming using a systematic approach that emphasizes the use of spreadsheet-based optimization tools. The Second Edition also features: Classifications for the various problem types, providing the reader with a broad framework for building and recognizing optimization models Network models that allow for a more general form of mass balance A systematic introduction to Data Envelopment Analysis (DEA) The identification of qualitative patterns in order to meaningfully interpret linear programming solutions An introduction to stochastic programming and the use of RSP to solve problems of this type Additional examples, exercises, and cases have been included throughout, allowing readers to test their comprehension of the material. In addition, a related website features Microsoft Office® Excel files to accompany the figures and data sets in the book. With its accessible and comprehensive presentation, Optimization Modeling with Spreadsheets, Second Edition is an excellent book for courses on deterministic models, optimization, and spreadsheet modeling at the upper-undergraduate and graduate levels. The book can also serve as a reference for researchers, practitioners, and consultants working in business, engineering, operations research, and management science.

Download or read book Operations Research written by H. A. Eiselt and published by Springer Science & Business Media. This book was released on 2010-05-17 with total page 455 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1960s, operations research (or, alternatively, management science) has become an indispensable tool in scientific management. In simple words, its goal on the strategic and tactical levels is to aid in decision making and, on the operational level, automate decision making. Its tools are algorithms, procedures that create and improve solutions to a point at which optimal or, at least, satisfactory solutions have been found. While many texts on the subject emphasize methods, the special focus of this book is on the applications of operations research in practice. Typically, a topic is introduced by means of a description of its applications, a model is formulated and its solution is presented. Then the solution is discussed and its implications for decision making are outlined. We have attempted to maximize the understanding of the topics by using intuitive reasoning while keeping mathematical notation and the description of techniques to a minimum. The exercises are designed to fully explore the material covered in the chapters, without resorting to mind-numbing repetitions and trivialization.
