• Vertical information exchange in a supply chain with duopoly retailers AI翻译

  摘要：We consider a supply chain with one manufacturer in the upstream and two competing retailers in the downstream. The retailers sell differentiated goods and are endowed with some private demand information. The paper shows that the manufacturer's optimal strategy is independent of the type of downstream competition, Cournot or Bertrand, and that no information will be shared with the manufacturer on a voluntary basis. However, complete information sharing, which benefits all three parties, can ...
• Time-based pricing and leadtime policies for a build-to-order manufacturer AI翻译

  摘要：We studied time-based policies on pricing and leadtime for a build-to-order and direct sales manufacturer. It is assumed that the utility of the product varies among potential customers and decreases over time, and that a potential customer will place an order if his or her utility is higher than the manufacturer's posted price. Once an order is placed, it will be delivered to the customer after a length of time called leadtime. Because of the decrease in a customer's utility during leadtime, ...
• Challenges posed to operations management by the new economy AI翻译

  摘要：A growing number of sophisticated observers are coming to believe that the forces driving the so-called New Economy are fundamentally reshaping world industry. Moreover, the combination of fast growth and the excitement associated with leading edge technologies has made New Economy companies magnets for management talent-and particularly for the ambitious young people who attend our management programs. Are we providing these potential managers with a good foundation for managing operations in...
• Service process configurations in electronic retailing: A taxonomic analysis of electronic food retailers AI翻译

  摘要：We developed a taxonomy of service processes in electronic retailing using data from 255 electronic food retailers. The taxonomy is comprised of eight service process configurations. Analysis of publicly available data on on-line customer ratings for 52 retailers in the study sample shows that the ordering of the configurations in the taxonomy on a continuum of low to high flexibility is associated positively with (i) customer satisfaction with web site aesthetics, web site navigation, product...
• From buyer to integrator: The transformation of the supply-chain manager in the vertically disintegrating firm AI翻译
  作者：Parker, GG; Anderson, EG Jr

  摘要：Using case study data, we describe how a large personal computer manufacturer changed its supply-chain management strategy after outsourcing the majority of its design and manufacturing activities to a network of focused suppliers. To cope with this new structure, the firm created highly skilled generalists, supply-chain integrators, who coordinate product development, marketing, production, and logistics from product concept to delivery across firm boundaries. We particularly focus on the ski...
• Job release control using a cyclic schedule AI翻译
  作者：Bowman, RA

  摘要：In just-in-time inventory management in any manufacturing setting, the general idea has been to release jobs as late as possible (to reduce inventory costs) while still having them arrive at bottleneck machines in time to maintain the desired throughput (by not starving a bottleneck machine). When a cyclic schedule is employed, the throughput is determined by a cyclic sequence of operations known as the cyclic critical path. These operations are not, in general, all performed on a single bottl...

• Effectiveness of stock transshipment under various demand distributions and nonnegligible transshipment times AI翻译

  摘要：This paper investigates the operational characteristics of a pooling group consisting of two stocking locations, supplied periodically by a central warehouse. The two locations may collaborate by moving inventory between them. The lateral transshipment times are shorter than the regular replenishment lead times, but they are not negligible. Several alter-native types of ordering and transshipment policies are examined. Extensive experimentation by simulation leads to the conclusion that the be...
• An empirical examination of the underlying dimensions of purchasing competence AI翻译

  摘要：The importance of evaluating the effectiveness of the purchasing function in firms along multiple criteria has attracted considerable attention. However, few studies have identified the defining elements that constitute purchasing competence. This paper introduces the construct of purchasing competence using a second-order factor structure derived from purchasing practices identified from the literature. The validity of the construct (purchasing competence) is tested using data from a sample o...
• Lot-sizing rule and freezing the master production schedule under capacity constraint and deterministic demand AI翻译
  作者：Zhao, XD; Xie, JX; Jiang, QY
  作者单位：Chinese University of Hong Kong; Tsinghua University
  摘要：This paper investigates the performance impact of lot-sizing rule (LSR) selection and freezing of the master production schedule (MPS) in multi-item single-level systems with a single resource constraint under deterministic demand. The results of the study show that the selection of LSRs and the parameters for freezing the MPS have a significant impact on total cost, schedule instability, and the service level of the system. However, the selection of LSRs does not significantly influence the s...
