一种基于多参数的IDS决策过程研究

讨论了将数据融合技术运用到入侵检测系统中的方法,并提出了一个基于数据融合技术的入侵检测机制-DFIDM。在该机制中,有多个检测器搜集系统日志文件、网络流量信息、网络数据包等数据,这些数据在通过了本地决策、数据提取和对象提取阶段等预处理过程之后,传送到融合中心进行决策,重点研究了决策过程所涉及的多参数问题。为此,系统设计了检测器可靠性、时间因素、空间因素等五个主要因素参与融合与决策。最后通过实验证明,采用了该机制的入侵检测系统具有更好的准确性。     

从单音反义形容词的句法失衡看聚合组合的多元对应

单间反义形容词在静态中具有聚合类聚的对应性,但在动态中具有句法组合的非对应性。产生这种状况的原因有:为追求效率性和经济性而导致的适量原则;有凸现显著性和积极性而产生的夸饰心理;有力求整体性和协调性而生成的互补原则;还有因缺乏形态标记而体现的灵活性和随意性的语法特征。

Large Matching Markets as Two‐Sided Demand Systems

This paper studies two‐sided matching markets with non‐transferable utility when the number of market participants grows large. We consider a model in which each agent has a random preference ordering over individual potential matching partners, and agents' types are only partially observed by the econometrician. We show that in a large market, the inclusive value is a sufficient statistic for an agent's endogenous choice set with respect to the probability of being matched to a spouse of a given observable type. Furthermore, while the number of pairwise stable matchings for a typical realization of random utilities grows at a fast rate as the number of market participants increases, the inclusive values resulting from any stable matching converge to a unique deterministic limit. We can therefore characterize the limiting distribution of the matching market as the unique solution to a fixed‐point condition on the inclusive values. Finally we analyze identification and estimation of payoff parameters from the asymptotic distribution of observable characteristics at the level of pairs resulting from a stable matching.     

MRP Planned Orders in a Multiple‐Supplier Environment with Differing Lead Times

This study examines a deterministic material requirements planning (MRP) problem where lead times at subsequent ordering moments differ. Adequate replenishment methods that can cope with lead time differences are lacking because of the order crossover phenomenon, that is, replenishment orders are not received in the sequence they are ordered. This study specifies how to handle order crossovers and recalculate planned order releases after an update of gross requirements. The optimal (s, S) policy is based on dynamic programing. The state space is kept to a minimum due to three fundamental insights. The performance of the optimal solution approach is compared with two heuristics based on relaxations and a benchmark approach in which order crossovers are ignored. A numerical analysis reveals that average cost savings up to 25% are possible if the optimal policy is used instead of the benchmark approach. The contribution of this study is threefold: (1) it generalizes theory on MRP ordering, allowing for lead time differences and order crossovers; (2) it develops new fundamental insights and an optimal solution procedure, leading to substantial cost saving; and (3) it provides good‐performing heuristics for a general and realistic replenishment problem that can replace the current replenishment methods within MRP.
