摘要：Every fall, millions of Americans enter betting pools to pick winners of the weekly NFL football games. In the spring, NCAA tournament basketball pools are even more popular. In both cases, teams that are popularly perceived as favorites gain a disproportionate share of entries. In large pools there can be a significant advantage to picking upsets that differentiate your picks from the crowd. In this paper, we present a model of betting pools that incorporates pool participant behavior. We use...

摘要：The confidentiality-via-camouflage (CVC) procedure was recently proposed as an alternative to existing procedures such as data perturbation for protecting the confidentiality of numerical data. In this paper, we show that CVC, implemented with certain parameters, could potentially disclose confidential information. We identify the conditions under which such compromise will occur. We provide new derivations for the database administrator to select CVC parameters to avoid such disclosure. We al...

摘要：Bollapragada and Morton (1999) present several well-performing heuristics for solving the periodic inventory problem with random yield and demand. Their approach is essentially based on a transformation of the single-period problem into a standard newsvendor problem with deterministic yield and random demand which, however, is supply dependent. In our note, we show that their evaluation of the respective optimality condition is not correct. This explains the steady deterioration of their myopi...

摘要：Rosling (2002) presents and analyzes five different cost-rate functions for single-item inventory models. The functions are referred to as Models 1-5. These errata correct an erroneous comment concerning Model 3 and render a rigorous argument for the functional form of Model 2.
