摘要：Human decision making in the newsvendor context has been analyzed intensively in laboratory experiments, where various decision biases have been identified. However, it is unclear whether the biases also exist in practice. We analyze the ordering decisions of a manufacturer who faces a multiproduct newsvendor problem with an aggregate service-level constraint. We find that the manufacturer broadly exhibits the same biases as subjects in the laboratory and is prone to another bias that has not ...

摘要：The present study focuses on the Mediterranean Sea migration crisis and investigates the effectiveness of search and rescue (SAR) operations alongside measures to reduce the number of deaths of migrants at sea. It also describes the stakeholders involved in SAR activities. The paper first analyzes secondary data and the results of 24 in-depth interviews in order to develop an analytical framework, which is then complemented by a system dynamics model to explore the complexity and interactions ...

摘要：We study a coordinated clinic and surgery appointment scheduling problem for in-advance scheduling of surgical patients. Our models seek to provide timely access to care by coordinating clinic and surgery appointments to ensure that patients can see a surgeon in the clinic and (if needed) schedule their surgery within a maximum wait time target based on patient classes. There are different types of uncertainty including the number of appointment requests, whether a patient requires surgery, an...

摘要：As supply chain channels physical, financial, and information flows as well as associated risks, a firm's supply chain information should be helpful in understanding and predicting its credit risks. Credit ratings, as an approximate but important measure of corporate credit risks, have been widely used by investors, creditors, and supply chain partners in their decision-making. This study studies the role of supply chain information in predicting companies' credit ratings. Using firm-level sup...

摘要：Recent years have seen robust growth in online medical consultation platforms. These platforms allow patients to access various healthcare services provided by doctors (e.g., health assessment, diagnosis, consultation, and supervision). In China, many such platforms allow patients to give small monetary gifts to doctors as an expression of gratitude. The implicit assumption is that expensive gifts influence doctors' medical service and generate conflicts of interest but small gifts do not. How...

摘要：Many operations are characterized by a trade-off between speed and quality. This calls for an exploration of effective strategies to balance the two metrics. This study investigates the separate and joint effect of quantity and quality feedback on both performance metrics in order picking. We collected data from two real-effort experiments with in total 212 participants, who conducted an order picking task in an experimental warehouse. The results of the main experiment show that giving only q...

摘要：This study aims to examine and design operational strategies for mixed flows of autonomous vehicles (AVs) and human-driven vehicles (HVs). We propose a stylized model wherein utilitarian individuals either drive HVs or take privately operated AVs that are collectively dispatched. In the baseline mixed policy where AVs and HVs share the same lanes, we find that AVs under-join the traffic (queue) while HVs over-join. We identify a crowding-out effect such that AVs will tend to mitigate the over-...

摘要：This paper studies the impact of channel structure on an upstream manufacturer's bundling incentive, with a focus on the implications of channel structure for bundling digital goods. We consider a distribution channel with a manufacturer and a retailer. The manufacturer produces two products and sells them either separately or in the form of bundles to end consumers through a downstream retailer. Our analysis reveals that a manufacturer may have a stronger incentive to bundle when selling thro...

摘要：Substitution is a commonly adopted strategy for matching the demand mix by appropriately allocating the supplies. The recent development of information technology has allowed firms to easily swap products to meet consumers' preferences. When formulating substitution policies, firms have to take into account the supply and demand conditions, as well as the cost and benefit of substitution. We formulate a dynamic model, in which the firm replenishes the product inventories from uncertain sources...
