摘要：Supplier sourcing strategies are a crucial factor driving supply chain success. In this paper, we investigate the implications of uncertain supplier reliability on a firm's sourcing decisions in an environment with stochastic demand. In particular, we characterize specific conditions under which a firm should choose a single versus multiple supplier sourcing strategy. In an environment with both uncertain demand and supply, we characterize the total order quantity, the number of suppliers sele...

摘要：We study a continuous-review acquisition problem, in which the raw material price follows a discrete-state Markov process and demand is compound Poisson. We show that one optimal policy is of the order-up-to type. Under our mean reversion and time continuity conditions, we further show that the order-up-to levels are decreasing at the current price level. At the same time, our computational study verifies that both conditions are indispensable for the monotonicity result. The study also hints ...

摘要：Make-to-order (MTO) manufacturers face a common problem of maintaining a desired service level for delivery at a reasonable cost while dealing with irregular customer orders. This research considers a MTO manufacturer who produces a product consisting of several custom parts to be ordered from multiple suppliers. We develop procedures to allocate orders to each supplier for each custom part and calculate the associated replenishment cost as well as the probability of meeting the delivery date,...

摘要：We model a situation where a firm wishes to balance workload requirements by creating a portfolio of recurrent insourcing and outsourcing contracts. We use harmonic analysis to decompose an input workload profile into a portfolio of insourcing and outsourcing contracts using rectangular-wave basis functions to better achieve some desired constant workload level. However, this initial selection of contracts may result in impractical options. Therefore, we also develop mathematical programs usin...

摘要：Few papers have explored the optimal reserve prices in the name-your-own-price (NYOP) channel with bidding options in a multiple channel environment. In this paper, we investigate a double-bid business model in which the consumers can bid twice in the NYOP channel, and compare it with the single-bid case. We also study the impact of adding a retailer-own list-price channel on the optimal reserve prices. This paper focuses on achieving some basic understanding on the potential gain of adding a ...

摘要：Product and waste take-back is becoming more regulated by countries to protect the environment. Such regulation puts an economic burden on firms, while creating fairness concerns and potentially even missing its primary target: environmental benefits. This research discusses the economic and environmental impacts of extended producer responsibility type of legislation and identifies efficiency conditions. It is shown that the right policy would (i) make producers responsible for their own wast...

摘要：It is common for suppliers operating in batch-production mode to deal with patient and impatient customers. This paper considers inventory models in which a supplier provides alternative lead times to its customers: a short or a long lead time. Orders from patient customers can be taken by the supplier and included in the next production cycle, while orders from impatient customers have to be satisfied from the on-hand inventory. We denote the action to commit one unit of on-hand inventory to ...

摘要：The Outsourcing Game is a role-play simulation that has been deployed in industry and academic training courses worldwide. It incorporates the concepts of hidden actions, hidden information, and misaligned incentives, and conveys messages about power, trust, and reputation. The game depicts the adventures of Acme, the brand owner of a product manufactured by an outsourced supply chain. Through a series of negotiations, Acme attempts to influence its partners (two suppliers and two service prov...

摘要：The computer software industry is an extreme example of rapid new product introduction. However, many consumers are sophisticated enough to anticipate the availability of upgrades in the future. This creates the possibility that consumers might either postpone purchase or buy early on and never upgrade. In response, many software producers offer special upgrade pricing to old customers in order to mitigate the effects of strategic consumer behavior. We analyze the optimality of upgrade pricing...

摘要：We investigate resource-constrained project scheduling with stochastic activity durations. Various objective functions related to timely project completion are examined, as well as the correlation between these objectives. We develop a GRASP-heuristic to produce high-quality solutions, using so-called descriptive sampling. The algorithm outperforms existing algorithms for expected-makespan minimization. The distribution of the possible makespan realizations for a given scheduling policy is als...
