摘要：In this study, we investigate the effects of recovery yield rate on pricing decisions in reverse supply chains. Motivated by the automotive parts remanufacturing industry, we consider an end-of-life product from which a particular part can be recovered and remanufactured for reuse, and the remainder of the product can be recycled for material recovery. Both the supply of end-of-life products and demand for remanufactured parts are price-sensitive. Yield of the recovery process is random and de...

摘要：We perform an analysis of various queueing systems with an emphasis on estimating a single performance metric. This metric is defined to be the percentage of customers whose actual waiting time was less than their individual waiting time threshold. We label this metric the Percentage of Satisfied Customers (PSC.) This threshold is a reflection of the customers' expectation of a reasonable waiting time in the system given its current state. Cases in which no system state information is availabl...

摘要：Manufacturers often face a choice of whether to recover the value in their end-of-life products through remanufacturing. In many cases, firms choose not to remanufacture, as they are (rightly) concerned that the remanufactured product will cannibalize sales of the higher-margin new product. However, such a strategy may backfire for manufacturers operating in industries where their end-of-life products (cell phones, tires, computers, automotive parts, etc.) are attractive to third-party remanuf...

摘要：We explore the value of information (VOI) in the context of a firm that faces uncertainty with respect to demand, product return, and product recovery (yield). The operational decision of interest in matching supply with demand is the quantity of new product to order. Our objective is to evaluate the VOI from reducing one or more types of uncertainties, where value is measured by the reduction in total expected holding and shortage costs. We start with a single period model with normally distr...

摘要：This paper proposes simple methods for staffing a single-class call center with uncertain arrival rate and uncertain staffing due to employee absenteeism. The arrival rate and the proportion of servers present are treated as random variables. The basic model is a multi-server queue with customer abandonment, allowing non-exponential service-time and time-to-abandon distributions. The goal is to maximize the expected net return, given throughput benefit and server, customer-abandonment and cust...

摘要：Closed-loop supply chains (CLSC) have product returns at the center of attention. Our view is that CLSC are best managed from a business perspective where organizations seek to maximize value recovery. The research in the feature issue, and our experiences, shows that there are still numerous, unresolved, managerially relevant issues that deserve further investigation. We also observe that there is a pressing need to validate the assumptions in our models using interdisciplinary, industry-driv...

摘要：This study presents a multi-period deterministic capacity planning problem with age-dependent capacity deterioration, i.e., the rate of deterioration for a capacity in a certain period depends on the time the capacity is acquired. Our problem has a number of general features such as demand fluctuation, operating and maintenance costs that depend on the amount of capacity utilized, capacity disposal, and capacity shortage. Formulated as a mixed integer programming model, we are able to exploit ...

摘要：In this paper, we study multi-stage serial supply chains with price dependent deterministic demand and increasing marginal costs. We analyze the effect of contract leadership (i.e., the ability to offer wholesale price and two-part tariff contracts) on supply chain performance and use that as a basis to study coordination and cooperation. There is strong evidence of first-mover advantage in wholesale price contracting which is amplified when the chain is coordinated using two-part tariff contr...

摘要：Many retail product returns can be refurbished and resold, typically at a reduced price. The price set for the refurbished products affects the demands for both new and refurbished products, while the refurbishment and resale activities incur costs. To maximize profit, a manufacturer in a competitive market must carefully choose the proportion of returned products to refurbish and their sale price. We model the sale, return, refurbishment, and resale processes in an open queueing network and f...

摘要：Diverse businesses, such as garbage collection, retail banking, and management consulting are often tied together under the heading of services, based on little more than a perception that then are intangible and do not manufacture anything. Such definitions inadequately identify managerial and operational implications common among, and unique to, services. We present a Unified Services Theory (UST) to clearly delineate service processes from non-service processes and to identify key commonali...
