  摘要：The procurement of maintenance, repair, and operating (MRO) goods has remained a relatively understudied topic in the literature. Though vital cost efficiencies can be extracted from procurement processes through investments in e-procurement systems, there is little empirical work that addresses how such systems should be deployed within organizations. In this study, we focus on the role of e-procurement systems in MRO procurement and study two critical aspects of infusion. The first dimension...
• Balancing Production and Distribution in Paper Manufacturing AI翻译

  摘要：A paper manufacturing plant minimizes its production cost by using long production runs that combine the demands from its various customers. As jobs are completed, they are released to distribution for delivery. Deliveries are made by railcars, each of which is dedicated to one customer. Long production runs imply that maximizing railcar utilization requires holding the cars over several days or holding completed jobs within the loading facility. Each of these methods imposes a cost onto the d...
• Flexibility Structure and Capacity Design with Human Resource Considerations AI翻译

  摘要：Most service systems consist of multidepartmental structures with multiskill agents that can deal with several types of service requests. The design of flexibility in terms of agents' skill sets and assignments of requests is a critical issue for such systems. The objective of this study was to identify preferred flexibility structures when demand is random and capacity is finite. We compare structures recommended by the flexibility literature to structures we observe in practice within call c...
• Staffing Call Centers with Uncertain Arrival Rates and Co-sourcing AI翻译

  摘要：In a call center, staffing decisions must be made before the call arrival rate is known with certainty. Once the arrival rate becomes known, the call center may be over-staffed, in which case staff are being paid to be idle, or under-staffed, in which case many callers hang-up in the face of long wait times. Firms that have chosen to keep their call center operations in-house can mitigate this problem by co-sourcing; that is, by sometimes outsourcing calls. Then, the required staffing N depend...
• Inventory Planning for a Modular Product Family AI翻译

  摘要：This paper is motivated by observing that an increasing number of firms are offering modular products assembled with multiple option choices for the consumer. Starting with the PC offerings by Dell which allowed (and still allows) users to configure their product by choosing among multiple choices for each option, the current market place seems to have evolved to a make-to-stock scenario where Apple offers its IPAD series with multiple models each with a unique storage size, color, and wireles...
• Up Then Down: Bid-Price Trends in Revenue Management AI翻译
  作者：Pang, Zhan; Berman, Oded; Hu, Ming

  摘要：In the classic revenue management (RM) problem of selling a fixed quantity of perishable inventories to price-sensitive non-strategic consumers over a finite horizon, the optimal pricing decision at any time depends on two important factors: consumer valuation and bid price. The former is determined exogenously by the demand side, while the latter is determined jointly by the inventory level on the supply side and the consumer valuations in the time remaining within the selling horizon. Becaus...
• Concerning Workload Control and Order Release: The Pre-Shop Pool Sequencing Decision AI翻译

  摘要：Every production planning concept that incorporates controlled order release will initially withhold jobs from the shop floor and create a pre-shop pool. Order release is a key component of the Workload Control concept that aims to maintain work-in-process within limits while ensuring due dates are met. Order release includes two decisions: (i) a sequencing decision that establishes the order in which jobs are considered for release; and, (ii) a selection decision that determines the criteria ...
• Maximizing Revenue Through Two-Dimensional Shelf-Space Allocation AI翻译

  摘要：We consider the problem of optimally allocating contiguous rectangular presentation spaces in order to maximize revenues. Such problems are encountered in the arrangement of products in retail shelf-space and in the design of feature advertising displays or webpages. Specifically, we allow (i) the shape of a product's presentation to have a vertical as well as a horizontal component and (ii) displays to extend across multiple shelves for in-store presentations. Since the vertical location of t...
• Fractional Price Matching Policies Arising from the Ocean Freight Service Industry AI翻译

  摘要：We consider a situation in which shippers (customers) can purchase ocean freight services either directly from a carrier (service provider)in advance or from the spot market just before the departure of an ocean liner. The price is known in the former case, while the spot price is uncertain ex-ante in the latter case. Consequently, some shippers are reluctant to book directly from the carrier in advance unless the carrier is willing to partially match the realized spot price when it is lower t...
• Implications of Channel Structure and Operational Mode Upon a Manufacturer's Durability Choice AI翻译

  摘要：Motivated by the observation that durability ratings of automobile manufacturers are not necessarily linked to the proportion of leasing but tend to decrease with the density of their dealer networks, we explore the interactions between channel structure (direct interaction with consumers vs. through an intermediary(ies)) and mode of operations (leasing vs. selling) and their implications for a manufacturer's willingness to invest in making her product more durable. Using a manufacturer who le...
