报告题目：Cooperative Functions
报告摘要：We study a common scenario in industry where returns to scale arenondecreasing and thus full cooperation via pooling all the resources togetheramong relevant firms is usually the most efficient way of production. Thisscenario is often modelled as a class of cooperative games, referred to asresource pooling games. We argue that resource pooling games could be betterunderstood via directly analyzing the underlying functions that are referred toas the cooperative functions than via analyzing the induced cooperative games.By combining the pioneering works of Sharkey and Telser (1978) and Aubin(1981), we provide a framework for analyzing cooperative functions. We focus oncooperative functions that are supportable in that nonemptiness of the core isguaranteed for all related resource pooling games, and argue that Aubin corecan be adapted to study cooperative functions and has several remarkableadvantages over the core. We characterize concave supportable functions andconvex supportable function. We find that a cooperative function always derivesa convex game if and only if it is ultramodular (i.e., supermodular andcoordinate-wise convex). Various related solution concepts, includingunnormalized Aubin core and PMAS, are studied. We also provide severalapplications of this framework, including linear production games, EOQ games,and newsvendor games.

报告题目：Procurementauction contract design for heterogeneous suppliers with reservation profitsconsideration
报告摘要：Weconsider a two-echelon supply chain system with one retailer with riskpreference and two heterogeneous suppliers with different costs and reservationprofits. In the system, the retailer's risk preference is quantified by thevalue-at-risk (VaR) measure and two suppliers compete the retailer's order withindividual reservation profit. For the supply chain coordination, we proposeoptimal two-part contracting auction mechanism, with which, channelcoordination can be achieved and hence Pareto improvement conditions can beillustrated in symmetric and asymmetric information scenarios. In addition, wecharacterize the effects of information asymmetry on the optimal decisions andderive insights to the value of information sharing.

报告题目：Routingand Scheduling management in Home Care Services
报告摘要：Routingand scheduling arrangements of home care are often affected by some unexpectedevents such as cancellation of services, demand for emergency care and medicaldevice failures. The above-mentioned events may lead to medical schedulingconflicts, and therefore might reduce patient satisfaction degree due to thedelayed service. We establish an effective real-time scheduling model andpropose an improved memetic algorithm. Finally, we analyze the practical effectof dispatching decision and put forward the recommendations for future researchdirections.
