摘要:The timing of vulnerability disclosures (by vulnerability discoverers) has significant implications for software producers and users. Immediate disclosure (before a patch becomes available) could result in exploits with subsequent harm to installed systems. Therefore, it is important to understand the determinants of this timing. In this study, we investigate the impacts of (i) the perception of the vulnerability discoverer about the software producer, (ii) the type of vulnerable software, and...

摘要:Inspired by the World Food Programme's activity in the post-civil war food crisis in Angola, this study proposes a systematic approach to address the location distribution problem in not-for-profit settings, where a limited volume of supply has to be allocated to different demand regions. The use of utility functions is key in our framework because it allows the decision-maker to establish priorities by representing the heterogeneous effects of distributing supply to different demand locations...

摘要:Most pricing and revenue management models have at their core an optimization problem; one needs to determine the optimal price or quantity to maximize a profit or revenue function. To ensure tractability, conditions that assure the objective function has a unique solution are enormously helpful. So far, several technical assumptions have been proposed for the continuous case, but comparatively little attention has been given to the discrete counterpart despite its prevalence in practice. Thus...

摘要:Driven by increasing costs in the traditionally regarded low-cost manufacturing bases (e.g., China), many firms have started to outsource their production to the regions of even lower costs (e.g., Southeast Asia). However, a new environment may involve higher cost uncertainty and severer information asymmetry. Motivated by these observations, we consider a sourcing game where competing firms choose between a supplier with transparent certain cost (type-C supplier) and a supplier with potential...

摘要:This study considers the scheduling of limited resources to a large number of jobs (e.g., medical treatment) with uncertain lifetimes and service times, in the aftermath of a mass casualty incident. Jobs are subject to triage at time zero, and placed into a number of classes. Our goal is to maximize the expected number of job completions. We propose an effective yet simple index policy based on Whittle's restless bandits approach. The problem concerned features a finite and uncertain time hori...

摘要:The two fundamental decisions in the management of perishable inventory are how much new inventory to order and how much old inventory to clear before expiration. These decisions are known to be difficult due to the curse of dimensionality. We propose policies that are much simpler and easier to implement than existing ones in the literature. Our analysis revealed interesting insights into the circumstances under which perishability is negligible. This intuition not only leads to the construct...

摘要:Emerging technologies such as drone delivery services enable retailers to cost-effectively offer unprecedented delivery speed and adaptable delivery lead times using dedicated aerial vehicles for individual orders. A natural and important question arises: What is the impact of a drone delivery system (DDS) on a retailer's extant logistics parameters, for example, the number of customer-facing delivery centers (last-mile warehouses) it uses and delivery lead times it offers? On the one hand, th...

摘要:Same-day delivery of online orders is becoming an indispensable service for large retailers. We explore an environment in which in-store customers supplement company drivers and deliver online orders on their way home. We consider a highly dynamic and stochastic same-day delivery environment in which online orders as well as in-store customers willing to make deliveries arrive throughout the day. Studying settings in which delivery capacity is uncertain is novel and practically relevant. Our p...

摘要:Confirmation bias, a well-established behavioral anomaly, asserts that when product experience is ambiguous, it is assimilated consistent with expectations set up by prior advertising. In this paper, we combine a strategic model with laboratory experiments to study the effects of consumers' confirmation bias on firms' advertising and pricing strategies and its implications for firms' profits. Our results suggest that confirmation bias does not improve firms' profits in the short run. However, ...

摘要:In an elegant study on salesforce incentive design, Steenburgh and Ahearne (2012) have argued that a multi-faceted portfolio approach, based on the classification of workers into laggards, core, and star performers, can induce better result from the salesforce, compared to traditional approaches used in companies. In this paper, we construct a portfolio of incentive contracts with a three-piece linear-quadratic-linear structure and study their incentive effects. It is well known that such cont...
