摘要:Capitalizing on the operational concept of division-of-labor, clinics often reduce physician service time by off-loading some of his/her clinical activities to lower-cost personnel. These personnel, such as nurse practitioners and physician assistants, are often collectively referred to as mid-level providers (MLPs) and can perform many patient-consultation tasks. The common rationale is that using an MLP allows the physician to serve more patients, increase patients' access to care, and, due ...

摘要:In today's increasingly globalized environment, more and more companies recognize the mutual dependence of supply chain partners in value creation. When making business decisions, they take into consideration their partners' bottom line profitability, especially in emerging markets. The question is, is this kind of practice sustainable? This study makes an attempt to formalize this issue by examining a stylized two-party supply chain model in which each player maximizes its own profit while ma...

摘要:We study an inventory management mechanism that uses two stochastic programs (SPs), the customary one-period assemble-to-order (ATO) model and its relaxation, to conceive control policies for dynamic ATO systems. We introduce a class of ATO systems, those that possess what we call a chained BOM. We prove that having a chained BOM is a sufficient condition for both SPs to be L? convex in the first-stage decision variables. We show by examples the necessity of the condition. For ATO systems with...

摘要:Today, software supports many important tasks in a variety of industries. In the specialized nature of these environments, a common problem faced by software vendors is to correctly signal the true value of a software product to the end users. For example, telecommunications equipment manufacturers design complex software for important functions like provisioning new users in the network. These software products automate various functions that would otherwise need to be done manually. In order...

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...
