  摘要：We examine the critical role of advance supply signalssuch as suppliers' financial health and production viabilityin dynamic supply risk management. The firm operates an inventory system with multiple demand classes and multiple suppliers. The sales are discretionary and the suppliers are susceptible to both systematic and operational risks. We develop a hierarchical Markov model that captures the essential features of advance supply signals, and integrate it with procurement and selling decis...

  摘要：This study examines how a firm can mitigate global economic risk through production hedging, defined as producing less than the total demand. We investigate a firm's production planning, pricing, and financial hedging decisions under exchange rate and demand uncertainty with the objective of maximizing expected profit while complying with a value-at-risk (VaR) constraint that limits the firm's losses in amount and probability. The study makes three contributions. First, we show that production...

  摘要：Material IQ (MiQ) is a new decision tool designed by GreenBlue to help suppliers safely share sensitive chemical-toxicity data with their customers. As GreenBlue takes MiQ to market, it must determine under what market conditions to promote the use of MiQ and when to recommend that a buyer uses its implementation as an opportunity to work with an existing supplier. We study GreenBlue's problem in two parts. First, we investigate when a buyer can use a wholesale price premium and/or buyer-suppl...
• An Optimization-Based Decision-Support Tool for Post-Disaster Debris Operations AI翻译

  摘要：Debris generated by disasters can hinder relief efforts and result in devastating economic, environmental, and health problems. In this study, we present a decision-support tool employing analytical models to assist disaster and waste management officials with decisions regarding collection, transportation, reduction, recycling, and disposal of debris. The tool enables optimizing and balancing the financial and environmental costs, duration of the collection and disposal operations, landfill u...
• Multi-Treatment Inventory Allocation in Humanitarian Health Settings under Funding Constraints AI翻译

  摘要：In humanitarian operations, the amount of funding received and the timing and predictability of funding strongly influence program performance. In this paper, we study the problem of allocating inventory procured using donor funding to patients in different health states over a finite horizon with the objective of minimizing the number of disease-adjusted life periods lost. The funding received and the number of new patients of different health states entering the program in every period could...
• Creativity and the Management of Technology: Balancing Creativity and Standardization AI翻译

  摘要：This thought piece represents an opportunity to integrate creativity and operations management (OM) research, and in particular the management of technology (MOT), to stimulate thinking and drive research across disciplines. Specifically, we discuss how there is an inherent tension when considering how work is organized and performed given that the majority of today's jobs require a certain degree of following routinized procedures, while some level of creativity is desirable as well. Therefor...
• Financial Hedging and Optimal Procurement Policies under Correlated Price and Demand AI翻译

  作者单位：Ihsan Dogramaci Bilkent University
  摘要：We consider a firm that procures an input commodity to produce an output commodity to sell to the end retailer. The retailer's demand for the output commodity is negatively correlated with the price of the output commodity. The firm can sell the output commodity to the retailer through a spot, forward or an index-based contract. Input and output commodity prices are also correlated and follow a joint stochastic price process. The firm maximizes shareholder value by jointly determining optimal ...
• Heuristics for Base-Stock Levels in Multi-Echelon Distribution Networks AI翻译

  摘要：We study inventory optimization for locally controlled, continuous-review distribution systems with stochastic customer demands. Each node follows a base-stock policy and a first-come, first-served allocation policy. We develop two heuristics, the recursive optimization (RO) heuristic and the decomposition-aggregation (DA) heuristic, to approximate the optimal base-stock levels of all the locations in the system. The RO heuristic applies a bottom-up approach that sequentially solves single-var...

  摘要：Even though more and more transactions and payments are conducted electronically, physical currency (banknotes and coins) still plays an essential role in commerce and trade, and it is expected to maintain its dominance in the near future. Over the past decade, several studies have analyzed various currency supply chains across the world. This study provides an overview of this research. The structure of a general banknote supply chain is given before the discussion of the problems from three ...
• Research on Idea Generation and Selection: Implications for Management of Technology AI翻译

  摘要：Idea generation and selection are fundamental activities in innovation. Scholars in many disciplines have written about these activities, addressing diverse perspectives. In this study, we synthesize the research findings most applicable to the management of technology. First, we present findings on the process of idea generation: the importance of problem recognition and the many decisions made in organizing the effort. Second, we present findings about the process of idea selection, focusing...
