摘要:In the automotive industry, many firms source key components from different suppliers, even though the components may function interdependently. In this study, we investigate how component level interdependence impacts quality performance and analyze how various operational factors moderate this relation. We synthesize information from several case studies to model the quality challenges faced by an automotive firm. For several sub-assemblies that go into its products, the firm sourced key com...

摘要:Discretionary commonality is a form of operational flexibility used in multi-product manufacturing environments. Consider a case where a firm produces and sells two products. Without discretionary commonality, each product is made through a unique combination of input and production capacity. With discretionary commonality, one of the inputs could be used for producing both products, and one of the production capacities could be used to process different inputs for producing one of the product...

摘要:Drug shortages have been a major challenge facing the US pharmaceutical industry and government in recent years. Although the problem has drawn tremendous attention from the government and media, limited academic research has been devoted to this problem, and few solutions have been proposed based on rigorous research. This study addresses the drug shortage problem from a supply chain perspective, a key aspect missing in the literature, and proposes to mitigate shortages through drug purchase ...

摘要:Subsidy programs are widely offered in both developing and developed countries to encourage consumption of products that generate positive social, health, and environmental externalities. We study the effect of subsidies on product consumption under uncertain market demand. To reach a target consumer population, the program sponsor may subsidize a for-profit or a not-for-profit firm on each unit of the product purchased by the firm or on each unit of the sale generated by the firm. We show tha...

摘要:We model a supply chain consisting of a supplier and multiple retailers facing deterministic demand. We denote some retailers as strategic in the sense that given the supplier inventory information, they will implement the optimal stocking policy by incorporating such information. On the other hand, some retailers are denoted as naive in the sense that they ignore supply information and resort to a simplistic ordering policy. Naive retailers learn the optimal policy over time and adjust their ...

摘要:Container seaports play an important role in cross-border logistics as firms increasingly expand their global footprint in sourcing, manufacturing and distribution. Besides convenience of access to hinterland regions, a key metric for a port's attractiveness is its processing time, that is, its ability to clear goods within a consistent, predictable time frame. Due to differences in infrastructure, government regulations, and operating procedures, ports may exhibit different degrees of predict...

摘要:We consider a finite-horizon, periodic-review model for a serial system with two uncapacitated external suppliers. While one external supplier (regular supplier) ships to the most upstream stage, the other one (emergency supplier) ships directly to a downstream stage. For this system, with general lead-times we show that the optimal cost function is multimodular with respect to inventories in transit and inventories at different stages and obtain results that show how the optimal order quantit...

摘要:Inventory displayed on the retail sales floor not only performs the classical supply function but also plays a role in affecting consumers' buying behavior and hence the total demand. Empirical evidence from the retail industry shows that for some types of products, higher levels of on-shelf inventory have a demand-increasing effect (billboard effect) while for some other types of products, higher levels of on-shelf inventory have a demand-decreasing effect (scarcity effect). This suggests tha...

摘要:Management of technology (MOT) concerns the processes by which innovations in technology are transformed to ultimately diffuse into the marketplace. As such, operations management contributes to the multidisciplinary realm of MOT through its study of a firm's resource capabilities. This special issue offers a broad and deep discussion on the interface between MOT and POM. The contributions of the MOT special issue are fourfold. First, we invited scholars from a variety of disciplines to write ...

摘要:This study analyzes subsidy schemes that are widely used in reducing waiting times for public healthcare service. We assume that public healthcare service has no user fee but an observable delay, while private healthcare service has a fee but no delay. Patients in the public system are given a subsidy s to use private service if their waiting times exceed a pre-determined threshold t. We call these subsidy schemes (s, t) policies. As two extreme cases, the (s, t) policy is called an unconditio...
