• Cellular Bucket Brigades on U-Lines with Discrete Work Stations AI翻译

  摘要：It is challenging to maximize and maintain productivity of a U-line with discrete stations under the impact of variability. This is because maximizing productivity requires assigning workers to suitable tasks and maintaining productivity requires sufficient flexibility in task assignment to absorb the impact of variability. To achieve this goal, we propose an operating protocol to coordinate workers on the U-line. Under the protocol the system can be configured such that its productivity is ma...
• Managing Disruptions in Decentralized Supply Chains with Endogenous Supply Process Reliability AI翻译

  摘要：Supply disruptions are all too common in supply chains. To mitigate delivery risk, buyers may either source from multiple suppliers or offer incentives to their preferred supplier to improve its process reliability. These incentives can be either direct (investment subsidy) or indirect (inflated order quantity). In this study, we present a series of models to highlight buyers' and suppliers' optimal parameter choices. Our base-case model has deterministic buyer demand and two possibilities for...
• Service Completion Estimates for Cross-trained Workforce Schedules under Uncertain Attendance and Demand AI翻译
  作者：Easton, Fred F.

  摘要：Although cross-trained workers offer numerous operational advantages for extended-hour service businesses, they must first be scheduled for duty. The outcome from those decisions, usually made a week or more in advance, varies with realized service demand, worker attendance, and the way available cross-trained workers are deployed once the demands for service are known. By ignoring the joint variability of attendance and demand, we show that existing workforce scheduling models tend to oversta...
• Vehicle Supply Chains in Humanitarian Operations: Decentralization, Operational Mix, and Earmarked Funding AI翻译

  摘要：The work of international humanitarian organizations (IHOs) frequently involves operating in remote locations, decentralized decision-making, and the simultaneous implementation of development and disaster response programs. A large proportion of this work is funded by earmarked donations, since donors often exhibit a preference for the programs they are willing to fund. From extensive research involving qualitative descriptions and quantitative data, and applying system dynamics methodology, ...
• Fairness in Selling to the Newsvendor AI翻译

  摘要：This paper studies the impact of fairness concerns on supply chain performance (SCP) in the two-party newsvendor setting. We extend prior fairness analysis to a wide range of demand distributions, and also allow the degree and definition of fairness to assume a broader range of preferences than those in prior literature. Contrary to prior literature, we find that if the retailer's ideal allocation to the supplier is not sufficiently large, regardless of demand variability, a fair-minded retail...
• Strategic Information Sharing in Competing Channels AI翻译

  摘要：We investigate strategic information sharing in two competing channels. The retailer in a channel can ex post decide whether to share private demand information with his upstream manufacturer after the content of information becomes known. We find that a retailer discloses low demand and withholds high demand to induce lower wholesale prices from his manufacturer. We show that a retailer should share less information when the retail market becomes more competitive, but should disclose more inf...
• Pricing and Operational Performance in Discretionary Services AI翻译
  作者：Tong, Chunyang; Rajagopalan, Sampath
  作者单位：Shanghai University of Finance & Economics; University of Southern California
  摘要：In many services, for example, website or landscape design, the value or quality derived by a customer depends upon the service time, and this valuation differs across customers. Customers procure the service based on the expected value to be delivered, prices charged, and the timeliness of service. We investigate the performance of the optimal pricing scheme as well as two commonly used pricing schemes (fixed fee and time-based pricing) for such services on important dimensions such as revenu...

• Dynamic Pricing and Inventory Management with Regular and Expedited Supplies AI翻译

  摘要：We consider a periodic-review inventory system with regular and expedited supply modes. The expedited supply is faster than the regular supply but incurs a higher cost. Demand for the product in each period is random and sensitive to its selling price. The firm determines its order quantity from each supply in each period as well as its selling price to maximize the expected total discounted profit over a finite or an infinite planning horizon. We show that, in each period if it is optimal to ...
