The fundamental concepts of simulation modelling are presented along with methodologies used in applying simulation to business and engineering problems. Written by the creators of SIMAN, a commercial simulation software package, this book presents practical examples in the SIMAN language.
This book is written for managers who are interested in learning more about the extraordinary challenges for delivering customer orders complete and on-time, the common scheduling solutions to those challenges, and how scheduling solutions have evolved over time. It is particularly relevant to managers that are not satisfied with their current cost of delivery performance, and face symptoms identified in key business performance indicators such as late orders, lost sales from long lead times, or high production cost. As we will show in this book the quality of the schedule can have a significant impact on the overall performance of the business. Good scheduling can provide an important competitive advantage for the enterprise. This book explains in non-technical terms, how a new ERP-APS-MES enabler can boost ROI from your business.

Researchers develop simulation models that emulate real-world situations. While these simulation models are simpler than the real situation, they are still quite complex and time consuming to develop. It is at this point that metamodeling can be used to help build a simulation study based on a complex model. A metamodel is a simpler, analytical model, auxiliary to the simulation model, which is used to better understand the more complex model, to test hypotheses about it, and provide a framework for improving the simulation study. The use of metamodels allows the researcher to work with a set of mathematical functions and analytical techniques to test simulations without the costly running and re-running of complex computer programs. In addition, metamodels have other advantages, and as a result they are being used in a variety of ways: model simplification, optimization, model interpretation, generalization to other models of similar systems, efficient sensitivity analysis, and the use of the metamodel's mathematical functions to answer questions about different variables within a simulation study.
Often management is the art of making strategic and tactical decisions with a total lack of objective information. How often do we wish for a crystal ball that would let us see how decisions today will play out in the future? Unfortunately it is not yet possible to predict the future, but it is possible to generate objective criteria to help make today's decisions. While simulation has been around for decades, recent advances have made it much more accessible and useful in our daily world. The software is now less expensive and easier to learn and use. And the flexibility and accuracy have dramatically improved. But most important, modern tools allow you to solve problems much faster than ev...

Batch chemical processing has in the past decade enjoyed a return to respectability as a valuable, effective, and often preferred mode of process operation. This book provides the first comprehensive and authoritative coverage that reviews the state of the art development in the field of batch chemical systems engineering, applications in various chemical industries, current practice in different parts of the world, and future technical challenges. Developments in enabling computing technologies such as simulation, mathematical programming, knowledge based systems, and prognosis of how these developments would impact future progress in the batch domain are covered. Design issues for complex unit processes and batch plants as well as operational issues such as control and scheduling are also addressed.
The process of industrialization that began over two hundred years ago is continuing to change the way people work and live, and doing it very rapidly, in places like China and India. At the forefront of this movement is the profession of industrial engineering that develops and applies the technology that drives industrialization. This book describes how industrial engineering evolved over the past two centuries developing methods and principles for the planning, design, and control of production and service systems. The story focuses on the growth of the discipline at Purdue University where it helped shape the university itself and made substantial contributions to the industrialization of America and the world. The story includes colorful and creative people like Frank and Lillian Gilbreth of Cheaper by the Dozen fame. Lillian was the first lady of American engineering as well a founder of Purdue's Industrial Engineering.
Material handling and logistics have become especially important to industrialists because of the competitive advantage that results from using the right methods to provide the right amount of the right material at the right place, at the right time, in the right condition, in the right sequence, in the right orientation, and at the right cost. But, what are the right methods? The emergence of sophisticated control systems, coupled with advances in hardware design, has resulted in a wide variety oftechno logical alternatives availablefor practically any application. Yet, with the emergence of just-in-time methods and the apparent success of the firms that have relied on the use of people and...
This proceedings volume contains selected and refereed contributions that were presented at the conference on "Recent Developments and New Perspectives of Operations Research in the Area of Production Planning and Control" in Hagen/Germany, 25. - 26. June 1992. This conference was organized with the cooperation of the FernuniversiHit Hagen and was jointly hosted by the "Deutsche Gesellschaft fur Operations Research (DGOR)" and the "Manufacturing Special Interest Group of the Operations Research Society of America (ORSA-SIGMA)". For the organization of the conference we received generous financial support from the sponsors listed at the end of this volume. We wish to express our appreciation ...
