• Process planning for aluminum tubes: An engineering-operations perspective AI翻译
  作者：Balakrishnan, A; Brown, S
  摘要：Metal-forming operations such as extrusion, drawing, and rolling offer many opportunities for operations improvement through better process understanding and improved planning practices. This paper addresses medium-term planning issues in aluminum tube manufacturing operations. First, we identify certain distinctive characteristics-the inherent process flexibility, close interdependence between successive stages, and economies of scale-of metal-forming operations, and identify performance trad...
• A production line that balances itself AI翻译

  摘要：In ''bucket brigade'' manufacturing, such as recently introduced to the apparel industry, a production line has n workers moving among m stations, where each worker independently follows a simple rule that determines what to do next. Our analysis suggests and experiments confirm that if the workers are sequenced from slowest to fastest then, independently of the stations at which they begin, a stable partition of work will spontaneously emerge. Furthermore, the production rate will converge to...
• Managing hotel reservations with uncertain arrivals AI翻译

  摘要：Based on our interactions with managers at two large hotels, we present a realistic model of the hotel reservation problem. Unlike traditional models, ours does not assume thar all customers arrive simultaneously on the targeted booking date. We explain why this assumption may not be appropriate for the hotel industry and develop a model of reservation booking which explicitly includes the room allocation decisions which are made on the targeted booking date. Based on observations of how the p...
• An analytical method for performance evaluation of kanban controlled production systems AI翻译
  作者：DiMascolo, M; Frein, Y; Dallery, Y
  作者单位：Sorbonne Universite
  摘要：The aim of this paper is to develop a general purpose analytical method for performance evaluation of multistage kanban controlled production systems. We consider a single-part type production system decomposed into stages in series. Each stage consists of a manufacturing cell and an output buffer. With each stage is associated a given number of kanbans. The kanban controlled production system is modeled as a queueing network with synchronization mechanisms. The basic principle of the proposed...
• Circuit partitioning via set partitioning and column generation AI翻译
  作者：EbenChaime, M; Tovey, CA; Ammons, JC
  作者单位：University System of Georgia; Georgia Institute of Technology
  摘要：In this paper, a new application of the methodology of set partitioning formulation augmented with heuristic column generation is presented. An efficient method for the partitioning of large-scale electronic circuits is developed based on this methodology. Circuit partitioning constitutes a major step of the physical design phase of electronic circuits, the fundamental components of electronic products. The major advantage of the scheme presented here is to provide a framework for an effective...
• An empirical investigation of the microstructure of knowledge acquisition and transfer through learning by doing AI翻译
  作者：Epple, D; Argote, L; Murphy, K
  作者单位：State University System of Florida; Florida International University
  摘要：Does knowledge acquired through learning by doing on one shift transfer to a second shift when it is introduced at a manufacturing plant? The answer to this question has important theoretical implications about where knowledge is embedded in organizations and about sources of productivity growth. The answer also has important practical implications for managers planning to introduce additional facilities. This paper analyzes the amount of transfer across shifts at a manufacturing facility. Spe...
• Reducing the cost of demand uncertainty through accurate response to early sales AI翻译
  作者：Fisher, M; Raman, A
  作者单位：Harvard University
  摘要：Traditionally, fashion products have incurred high losses due to stockouts and inventory obsolence because long lead times coupled with a concentrated selling season force all or at least most production to be committed before demand information is available. Under a Quick Response system, lead times are shortened sufficiently to allow a greater portion of production to be scheduled in response to initial demand. We model and analyze the decisions required under Quick Response and give a metho...
• Valuing operational flexibility under exchange rate risk AI翻译
  作者：Huchzermeier, A; Cohen, MA
  作者单位：University of Chicago; University of Pennsylvania
  摘要：In this paper, we develop a stochastic dynamic programming formulation for the valuation of global manufacturing strategy options with switching costs. Overall, we adopt a hierarchical approach. First, exchange rates are modeled as stochastic diffusion processes that exhibit intercountry correlation. Second, the firm's global manufacturing strategy determines options for alternative product designs as well as supply chain network designs. Product options introduce international supply flexibil...
• Exploratory evidence on the behavior of quality costs AI翻译
  作者：Ittner, CD
  摘要：This study examines the time series behavior of quality costs reported by 49 manufacturing units of 21 companies. Analyses using both pooled annual data and plant-specific quarterly data indicate that the majority of units in the sample achieved ongoing reductions in nonconformance costs while maintaining or reducing reported prevention and appraisal costs. These findings are consistent with recent quality-based learning and continuous improvement models which suggest that, once an effective q...
