论武警法律体系构建与完善

武警法律体系是以武警法为核心,由现行的各种军事法律规范和武警规章为基础,以武警基本法、武警组织法、武警行为法、武警保障与监督检查法等武警法分支为主体而组成的内容协调一致的有机整体。本文是从武警法律体系的角度讨论贯彻实施《人民武装警察法》。从理论的层面讨论有关武警法律体系的内容。

What you should know about simulation and derivatives

Derivatives (or gradients) are important for both sensitivity analysis and optimization, and in simulation models, these can often be estimated efficiently using various methods other than brute‐force finite differences. This article briefly summarizes the main approaches and discusses areas in which the approaches can most fruitfully be applied: queueing, inventory, and finance. In finance, the focus is on derivatives of another sort. © 2008 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

Bayesian enhanced decision making for deteriorating repairable systems with preventive maintenance

Since a system and its components usually deteriorate with age, preventive maintenance (PM) is often performed to restore or keep the function of a system in a good state. Furthermore, PM is capable of improving the health condition of the system and thus prolongs its effective age. There has been a vast amount of research to find optimal PM policies for deteriorating repairable systems. However, such decisions involve numerous uncertainties and the analyses are typically difficult to perform because of the scarcity of data. It is therefore important to make use of all information in an efficient way. In this article, a Bayesian decision model is developed to determine the optimal number of PM actions for systems which are maintained according to a periodic PM policy. A non‐homogeneous Poisson process with a power law failure intensity is used to describe the deteriorating behavior of the repairable system. It is assumed that the status of the system after a PM is somewhere between as good as new for a perfect repair and as good as old for a minimal repair, and for failures between two preventive maintenances, the system undergoes minimal repairs. Finally, a numerical example is given and the results of the proposed approach are discussed after performing sensitivity analysis. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2008     

村民自治对农村社会稳定的双面效应

村民自治对农村社会稳定起着正面效应;异化的村民自治对农村社会稳定起着负面效应。鉴于此,为在农村社会发展中实现农村社会稳定,就要不断强化其正面效应,弱化其负面效应。     

社会保障与社会稳定关联性探析

社会保障制度作为“社会安全阀”,其与社会稳定之间存在正相关关系;但在实践中,由于我国社会保障制度不健全,保障调节功能弱化,又影响了社会稳定,其与社会稳定之间存在负相关关系。因此,必须尽快建立一套完整而切实可行的社会保障制度,以保证社会的稳定与发展。

Directional change‐point detection for process control with multivariate categorical data

Most modern processes involve multiple quality characteristics that are all measured on attribute levels, and their overall quality is determined by these characteristics simultaneously. The characteristic factors usually correlate with each other, making multivariate categorical control techniques a must. We study Phase I analysis of multivariate categorical processes (MCPs) to identify the presence of change‐points in the reference dataset. A directional change‐point detection method based on log‐linear models is proposed. The method exploits directional shift information and integrates MCPs into the unified framework of multivariate binomial and multivariate multinomial distributions. A diagnostic scheme for identifying the change‐point location and the shift direction is also suggested. Numerical simulations are conducted to demonstrate the detection effectiveness and the diagnostic accuracy.© 2013 Wiley Periodicals, Inc. Naval Research Logistics, 2013
