摘要：Optimization approaches for planning and routing of humanitarian field operations have been studied intensively. Yet, their adoption in practice remains scant. This opinion paper argues that effectiveness increase realized by such approaches can be marginal due to triviality of planning problems, external constraints, and information losses. Cost increases, on the other hand, can be substantial. These include costs of implementation and use, data gathering, and mismatches with organizational c...

摘要：Trade-in programs for electronics products, e.g., mobile phones, have been increasingly popular. These programs target at customers (we call them bargainers) who seek to salvage or upgrade their old devices. There are two widely adopted trade-in options: trade-in-for-upgrade and trade-in-for-cash. In this study, we consider a firm who offers both trade-in options, that is, a hybrid trade-in program, to acquire old products, then refurbishes and resells them, together with new product over a fi...

摘要：Volunteer convergence refers to the influx of volunteers to affected areas after large-scale disasters. There are not only many benefits to volunteer convergence, but it also creates significant logistical challenges that can impede relief efforts. This study examines polices for admitting volunteers into organized relief operations, and for assigning admitted volunteers to relief tasks. We represent this problem as a queueing system where, in addition to customer arrivals and departures, rand...

摘要：Transaction cost economics (TCE) is one of the most widely referenced organization theories in operations and supply chain management research. Even though TCE is a broadly applicable theory of governance, one of its specific topics of interest-the make-or-buy decision-readily aligns with some of the central research questions on how firms manage supply chains. However, both general management and operations management researchers sometimes misunderstand and misapply TCE's aims, assumptions, a...

摘要：We examine inventory decisions in a multiperiod newsvendor model. In particular, we analyze the impact of budget cycles in a behavioral setting. We derive optimal rational decisions and characterize the behavioral decision-making process using a short-sightedness factor. We test the aforementioned effect in a laboratory environment. We find that subjects reduce order-up-to levels significantly at the end of the current budget cycle, which results in a cyclic pattern during the budget cycle. Th...

摘要：Product proliferation and changes in demand require that retailers regularly determine how items should be allocated to retail shelves. The existing shelf-space literature mainly deals with regular retail shelves onto which customers only have a frontal perspective. This study provides a modeling and solution approach for two-dimensional shelves, e.g., for meat, bread, fish, cheese, or clothes. These are categories that are kept on tilted shelves. Customers have a total perspective on these sh...

摘要：This study is motivated by the ubiquitous practical existence of common retailer distribution channels (e.g., a grocery store offering multiple brands of the same product). Demand interdependence (product substitutability) among various brands is critical and thus we investigate its impact on firms' profits. Using an economic framework with manufacturers operating as Stackelberg leaders, our analysis reveals unique and substantive insights dependent on the underlying market demand structure, a...

摘要：This study investigates the efficacy of zero-interest early payment financing (alternatively referred to as early payment) and positive-interest in-house factoring financing in a pull supply chain with a capital-constrained manufacturer selling a product through a capital-abundant retailer. Early payment is the prepayment of a wholesale cost to the manufacturer, whereas in-house factoring is a loan service provided to the manufacturer by a branch financing firm of the same retailer. We find th...

摘要：Social media-based online communities are becoming increasingly popular for various social interactions, including those for healthcare and health-related activities. The benefits from these activities, however, are constrained by how a platform is designed, as a platform's design defines what activities can be done and how individuals can engage and interact on the platform. In this study, we focus on weight-loss communities and social tools that facilitate social communication and establish ...

摘要：Using laboratory experiments, we study how communication media affect cooperation in a supply chain when the buyer has private information about the end-customer demand. We show that coordinating contracts (quantity discount) combined with efficient means to electronically share private information (one-way, pre-defined text message) result in almost efficient outcomes, but only if verbal communication takes place before the actual contracting stage. Content analysis shows that verbal communic...
