摘要：Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness-to-pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates d...

摘要：We consider a multi-stage inventory system with stochastic demand and processing capacity constraints at each stage, for both finite-horizon and infinite-horizon, discounted-cost settings. For a class of such systems characterized by having the smallest capacity at the most downstream stage and system utilization above a certain threshold, we identify the structure of the optimal policy, which represents a novel variation of the order-up-to policy. We find the explicit functional form of the o...

摘要：We study buyer-determined procurement auctions where both price and non-price characteristics of bidders matter for being awarded a contract. Although, in scoring auctions bidders perfectly know how price and non-price attributes determine the awarding of the contract, this remains uncertain in buyer-determined auctions where the buyer is free to choose once all bids have been submitted. We analyze the impact of information bidders have with respect to the buyer's awarding decision. As we show...

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：Health information exchanges (HIEs) are new organizational forms in the United States that facilitate digital exchange of health data across participants. Many believe that these multi-sided digital platforms will become key enablers of the digital transformation of healthcare in the United States. However, like other entrepreneurial ventures, HIEs face challenges to achieve operational maturity and financial viability. Entrepreneurial ventures often fail to attain financial viability due to t...

摘要：Service level agreements (SLAs) are widely adopted performance-based contracts in operations management practice, and fill rate is the most common performance metric among all the measurements in SLAs. Traditional procedures characterizing the order-up-to level satisfying a specified fill rate implicitly assume an infinite performance review horizon. However, in practice, inventory managers are liable to maintain and report fill rates over a finite performance review horizon. This horizon disc...

摘要：L arge-scale, web-based service marketplaces have recently emerged as a new resource for customers who need quick resolutions for their short-term problems. Due to the temporary nature of the relations between customers and service providers (agents) in these marketplaces, customers may not have an opportunity to assess the ability of an agent before their service completion. On the other hand, the moderating firm has a more sustained relationship with agents, and thus it can provide customers...

摘要：Legal studies usually treat a policy of a manufacturer or retailer as socially harmful if it reduces product output and increases the price. We consider a two-period model where the first-period price is fixed and resellers endogenously decide to use meet-the-competition clause with a most-favored-customer clause (MFC) to counteract strategic customer behavior. As a result of MFC, the second-period (reduced) price increases and resellers' inventories decrease. However, customer surplus may inc...

摘要：We consider manufacturer rebate competition in a supply chain with two competing manufacturers selling to a common retailer. We fully characterize the manufacturers' equilibrium rebate decisions and show how they depend on parameters such as the fixed cost of a rebate program, market size, the redemption rate of rebate, the proportion of rebate-sensitive consumers in the market and competition intensity. Interestingly, more intense competition induces a manufacturer to lower rebate value or st...

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...
