摘要：Many service systems that work with appointments, particularly those in healthcare, suffer from high no-show rates. While there are many reasons why patients become no-shows, empirical studies found that the probability of a patient being a no-show typically increases with the patient's appointment delay, i.e., the time between the call for the appointment and the appointment date. This paper investigates how demand and capacity control decisions should be made while taking this relationship i...

摘要：Systems thinking has proven useful in project management planning activities and has been suggested as a critical driver of a range of beneficial organizational behaviors. Yet, empirical evidence on the myriad of ways in which systems thinking can impact internal project dynamics and performance remains limited. This study focuses on one aspect of systems thinking in particular: the ability to recognize and understand the dynamics of systems and their features (e.g., feedback and delay). It ma...

摘要：In health care, most quality transparency and improvement programs focus on the quality variation across hospitals, while we know much less about within-hospital quality variation. This study examines one important factor that is associated with the fluctuation of quality of care in the same hospitalthe timing of patient arrival. We analyze data from the National Trauma Data Bank and find that patients arriving at the hospital during off-hours (6PM-6AM) receive significantly lower quality care...

摘要：Advertising is a crucial tool for demand creation and market expansion. When a manufacturer uses a retailer as a channel for reaching end customers, the advertising strategy takes on an additional dimension: which party will perform the advertising to end customers. Cost sharing (co-operative advertising) arrangements proliferate the option by decoupling the execution of the advertising from its funding. We examine the efficacy of cost sharing in a model of two competing manufacturer-retailer ...

摘要：We empirically examine the association between downstream firms', i.e., customers' capital market information quality, and the operating performance of upstream firms, i.e., suppliers. Customers' capital market information quality is measured by the customers' provision of earnings forecasts, the customers' reported earnings quality, and the customers' coverage by financial analysts and credit rating agencies. We hypothesize and find a positive association between customers' capital market inf...

摘要：A pre-pack is a collection of items used in retail distribution. By grouping multiple units of one or more stock keeping units (SKU), distribution and handling costs can be reduced; however, ordering flexibility at the retail outlet is limited. This paper studies an inventory system at a retail level where both pre-packs and individual items (at additional handling cost) can be ordered. For a single-SKU, single-period problem, we show that the optimal policy is to order into a band with as few...

摘要：This paper studies appointment scheduling for a combination of routine patients who book well in advance and last-minute patients who call for an appointment later that same day. We determine when these same-day patients should be scheduled throughout the day, and how the prospect of their arrivals affects the appointment times of the routine patients. By formulating the problem as a stochastic linear program, we are able to incorporate random and heterogeneous service times and no-show rates,...

摘要：The basis for this article is an information-processing view of the UN's cluster approach. We use agent-based modeling and simulations to show that clusters, if properly utilized, encourage better information flow and thus facilitate effective response to disasters. The article intends to turn the attention of the humanitarian community to the importance of sharing information and the role of cluster leads in facilitating humanitarian aid. Our results indicate that if cluster leads act as info...
