Opis

With the pressure of time-based competition increasing, and customers demanding faster service, the availability of service parts becomes a critical component of manufacturing and servicing operations. Potentially, the aftermarket service industry may account for 25% of a manufacturer's annual revenue. On the other hand, keeping too many of such spare parts increases operational costs and eats up the bottom line. The challenge is the erratic demand patterns of service parts. Demand commonly is intermittent with some time periods having no demand at all. Forecasting for intermittent demand itself has long been recognized, in the academic literature, as a very difficult business task. It is not only the variability of the demand size but also the variability of the demand pattern that makes intermittent demand so difficult to forecast. Hence management of service parts is a significant organizational problem. Therefore, small improvements in a company's system, regarding service parts, may be translated to substantial cost savings. Service Parts Management provides an overview and detailed treatment of the current state of the research available on the forecasting and inventory management of items with intermittent demand. The book is divided into two parts, one for demand forecasting and one for inventory control. Demand forecasting techniques are presented for parametric and nonparametric approaches. Error measures, distributional assumptions, and the effects of correlation are all examined in the forecasting context while inventory control is examined in the continuous and periodic review cases. Multi echelon cases and inventory pooling are also considered. An excellent reference for key concepts and a leading resource for further research, Service Parts Management guides researchers and practitioners in finding better management solutions to their problems.

Recenzje

From the reviews:

"Service Parts Management: Demand Forecasting and Inventory Control covers a wide spectrum of relevant issues on spare parts management. With contributions from some of the most active researchers in this field, the book provides a great foundation for academics who want to explore this field in detail and offers useful advice to managers. ... In conclusion, the book offers practitioners and researchers a reasonably complete and good overview of relevant issues in spare parts management." (Ruud Teunter, Interfaces, Vol. 42 (1), January-February, 2012)

O autorze

Nezih Altay is Associate Professor of Operations Management. He holds a PhD in Operations Management from Texas A&M University and an MBA from the University of Texas – Pan American. His research focusing on forecasting and inventory control of spare parts has been highlighted in major academic conferences and published in leading journals, such as the International Journal of Production Economics. His work in this area resulted in a Royal Society grant through which he started new projects on the management of spare parts with colleagues in the UK. Currently in the USA, he is in collaboration with the Defense Logistics Agency on improving service parts forecasts and inventory control. Dr. Altay sits on the editorial boards of Production and Inventory Management Journal and the International Journal of Services Sciences, and is an active member of APICS, POMS, DSI, ISM, and INFORMS.   Lewis A. Litteral is a member of the faculty of the University of Richmond.  He holds a PhD in Management Science from Clemson University, where he also earned a Master of Science degree in mathematical sciences with a concentration in statistics. He currently teaches courses in statistical analysis although he has taught a wide variety of other quantitative courses over the past 30 years. His current research interests include enterprise resource planning, forecasting intermittent demand, and statistical quality control. The common thread in this work is that it all lies at the intersection of information technology and operations management. His work in these areas has been published by various journals including Production and Inventory Management, Quality Engineering, the International Journal of Production Economics and the International Journal of Quality and Standards. Prior to beginning an academic career, he was employed by a large building materials supply company where his positions included all aspects of operations management, as well as sales.

With the pressure of time-based competition increasing, and customers demanding faster service, availability of service parts becomes a critical component of manufacturing and servicing operations. Service Parts Management first focuses on intermittent demand forecasting and then on the management of service parts inventories. It guides researchers and practitioners in finding better management solutions to their problems and is both an excellent reference for key concepts and a leading resource for further research.   Demand forecasting techniques are presented for parametric and nonparametric approaches, and multi echelon cases and inventory pooling are also considered. Inventory control is examined in the continuous and periodic review cases, while the following are all examined in the context of forecasting: • error measures, • distributional assumptions, and • decision trees.   Service Parts Management provides the reader with an overview and a detailed treatment of the current state of the research available on the forecasting and inventory management of items with intermittent demand.  It is a comprehensive review of service parts management and provides a starting point for researchers, postgraduate students, and anyone interested in forecasting or managing inventory.
