摘要：We address a production/inventory problem for a single product and machine where demand is Poisson distributed, and the times for unit production and setup are constant. Demand not in stock is lost. We derive a solution for a produce-up-to policy that minimizes average cost per unit time, including costs of setup, inventory carrying, and lost sales. The machine is stopped periodically, possibly rendered idle, set up for a fixed period, and then restarted. The average cost function, which we de...

摘要：Firms have been proactively holding data science competitions via online contest platforms to look for innovative solutions from the crowd. When firms are designing such competitions, a key question is What should be a better contest design to motivate contestants to exert more effort? We model two commonly observed contest structures (one stage and two stage) and two widely adopted prize structures (high spread and low spread). We employ economic experiments to examine how contest design affe...

摘要：Nonhomogeneous Poisson process models have commonly been used to analyze and forecast arrivals. Such processes require specification of intensity (arrival rate) functions, which are typically defined in a parametric form. The accuracy of the parametric models is highly sensitive to the choice of the specific intensity function for the arrival process. We use a Bayesian framework by proposing a nonparametric form for the intensity function and introduce a robust semiparametric model. The model ...

摘要：Retailers may collaborate with key suppliers to manage some specified categories. This collaboration is often formalized as a captainship arrangement between the retailer and her leading supplier in the category. The designated category captain assists the retailer with category management decisions. We show that captainship arrangements have the potential to generate a valuable information effect for the retailer: nonprice decisions by the category captain can reveal information that allows t...

摘要：This paper aims at linking the work presented in Dauzere-Peres et al. (1998) and more recently in Kasapidis et al. (2021) on the multiresource flexible job-shop scheduling problem with nonlinear routes or equivalently with arbitrary precedence graphs. In particular, we present a mixed integer linear programming (MIP) model and a constraint programming (CP) model to formulate the problem. We also compare the theorems introduced in Dauzere-Peres et al. (1998) and Kasapidis et al. (2021) and prop...

摘要：While the existing literature has studied the impact of demand uncertainty extensively within various monopoly settings, there is little research on its impact among competitive retailers. In this paper, we study the effects of demand uncertainty reduction in a setting with two newsvendor retailers competing on product availability. We parameterize the uncertainty level via a mean-preserving spread and investigate the behavior of both retailers' equilibrium stocks and their expected profits in...

摘要：Firms innovate their new processes and products not only within their countries but also across national boundaries. This is known as cross-border innovation, and many countries have initiated policies to support it. But how does government support influence cross-border innovation? Through the lens of Porter's diamond model, this study conceptualizes government support as slack resources and investigates how it affects a firm's inventive activities in an uncertain, competitive global market. ...

摘要：Up to 20% of all business-to-consumer deliveries fail on the first attempt. Failed deliveries not only carry cost implications but also incur damage to retailers' brand reputation. Despite its economic significance, research has paid little attention to delivery attempt as an operational outcome or seldom accounted for its effects in routing models. This is partly due to the many factors that can influence delivery outcomes. We address this knowledge gap by first demonstrating that failed deli...

摘要：The recent outbreak of Coronavirus disease 2019 (COVID-19) has posed serious threats and challenges to global supply chain management (GSCM). To survive the crisis, it is critical to rethink the proper setting of global supply chains and reform many related operational strategies. We hence attempt to reform the GSCM from both supply and demand sides considering different pandemic stages (i.e., pre, during, and post-pandemic stages). In this research paper, we combine a careful literature revie...

摘要：We study how to admit and schedule heterogeneous patients by using simple, interpretable, yet effective policies when capacity is scarce, no-show behavior is patient- and time-dependent, service duration and reward are deterministic but patient-dependent, and overtime is costly. Our work is motivated by the aforementioned operational challenges that typically face adopters of new technologies in the healthcare sector. We anchor our study on a partnership with the proton therapy center of Massa...
