摘要：Accountable care organizations (ACOs) are responsible for the quality and cost of care of specified patient populations, including the cost of referrals. Motivated by this environment, we study care coordination for healthcare referrals. We consider an ACO that refers an uncertain number of patients from its attributed population to a preferred external provider for specialized health services. ACOs are typically paid under the Medicare Shared Savings Program (MSSP). Under the MSSP, the payer ...

摘要：We study the co-opetition strategy between a manufacturer of a proprietary component (MPC) and an original equipment manufacturer (OEM). The MPC can choose to supply components to the OEM and can also compete in the end market with its own final product. Customers can purchase from either firm and are strategic in that they choose whether to buy now or later. In a two-period game theoretical model, we analyze the MPC's optimal co-opetition strategy, which mainly concerns whether to sell to the...

摘要：Determining inventory ahead of knowing customer demand is a crucial decision for many businesses. Although it is possible to select the ideal order quantity given the costs of over and undersupplying demand, prior research demonstrates that decision-makers consistently make suboptimal inventory choices. Drawing on construal level theory and psychological distance, this paper explores how differences in the spatial distance (suppliers that are geographically near or far) and temporal distance (...

摘要：Fixed costs of ordering items or setting up a production process arise in many real-life scenarios. In their presence, the most widely used ordering policy in the stochastic inventory literature is the (s,S) policy. Optimality of (s,S) policies and (s,S)-type policies have been examined for various inventory models, including those with the inventory level being reviewed in every period or continuously, finite and infinite horizons, discounted-cost and average-cost criteria, backlogging and lo...

摘要：Most developed countries hold significant quantities of medical supplies in reserve for emergency response. Due to high handling costs and remote storage locations, such stocks are typically not used for day-to-day operations. In consequence, the expiry of reserve supplies (without use) is a significant problem. One possible remedy for such wastage is to donate large batches of dated supplies to developing nations, which often do without adequate medical supplies in their health systems. Here,...

摘要：The path for elevating the role of manufacturing in the company strategy in the last few decades has been rather clear: Improve the basic production capabilities-typically quality, reliability, lead times, and cost efficiency of production processes. Leading Japanese companies, like Toyota, showed the way. But as many have heeded the advice and followed suit, this approach has become essentially a defensive strategy; you must do it not to fall behind. Has manufacturing lost its potential to cr...

摘要：The enforcement of ever-stringent regulatory requirements capping emission limits is challenging the traditional operations of various transportation sectors. In maritime transportation, the recent regulation tightening fuel sulfur limits to 0.50%, known as the IMO 2020, has been enforced. There is a flurry of activities by ocean carriers to equip their vessels to comply with this regulation. Although the technical conditions are clear, investment decisions are hard to make due to inevitable u...

摘要：This paper studies the interaction between two key quality management decisions-input conformance quality and inspection policy-and related wholesale and retail prices in a two echelon supply chain. Market demand depends on the retail price as well as the end-product conformance quality, which itself depends on the input quality and the inspection scheme. Consistent with previous empirical findings in the literature, we show that an increase in quality does not always result in higher prices f...
