Bayesian life test planning for the Weibull distribution with given shape parameter

This paper describes Bayesian methods for life test planning with Type II censored data from a Weibull distribution, when the Weibull shape parameter is given. We use conjugate prior distributions and criteria based on estimating a quantile of interest of the lifetime distribution. One criterion is based on a precision factor for a credibility interval for a distribution quantile and the other is based on the length of the credibility interval. We provide simple closed form expressions for the relationship between the needed number of failures and the precision criteria. Examples are used to illustrate the results.Received: October 2002 / Revised: March 2004     

The Bell Curve in Psychological Research and Practice: Myth or Reality?

The expression “the bell curve” designs both a kind of statistical distribution and the title of a famous and controversial book by Herrnstein and Murray. The first is so attractive that the second refers to it to give more credibility to its questionable theories on intelligence. The point is that, during the 20th century, the bell curve has assumed a more and more important role in psychological research and practice and have become both a reality and a myth. In the first case (reality) we can assist to appropriate applications of a real useful statistical concept. In the second (myth) we can have two kinds of attitudes: one attitude is typical of those researchers who search for normality in all their data and variables, just as Parsifal used to search for the Holy Graal (we call this “the Parsifal attitude”); the other is typical of those researchers who give normality for granted and act as if it were a Platonic Idea (we call this “the Plato attitude”). The article discusses the role of the normal distribution in psychological research and practice and shows how it can be dangerous to treat the bell curve as a God or an Idol.

ON THE FIRST–ORDER EFFICIENCY AND ASYMPTOTIC NORMALITY OF MAXIMUM LIKELIHOOD ESTIMATORS OBTAINED FROM DEPENDENT OBSERVATIONS

Abstract. In this paper we study the first–order efficiency and asymptotic normality of the maximum likelihood estimator obtained from dependent observations. Our conditions are weaker than usual, in that we do not require convergences in probability to be uniform or third–order derivatives to exist.
The paper builds on Witting and Nolle's result concerning the asymptotic normality of the maximum likelihood estimator obtained from independent and identically distributed observations, and on a martingale theorem by McLeish.     

团队合作中的利益分配机制及其调整过程探讨

本文主要探讨团队合作这种新兴工作机制的利益分配机制,首先提出了两种方法:其一,权的最小平方法,建立在专家评分基础之上,具有一定的主观性;其二,在合作博弈框架之上运用Shapley定理确定分配方案,具有较好的客观性、公正性。本文后一部分主要讨论在使用Shapley定理确定分配方案之后的团队博弈,即一旦团队由合作博弈进入非合作博弈后,团队利益分配是如何进行调整的,以及调整过程中博弈双方的策略变化和这种调整产生的内在机理。     

基于仿真技术的物流中心站台数确定方法研究

通过建立描述站台数量的模型,利用排队论理论得到了最优站台数的解法,同时利用Arena仿真软件对这一问题进行仿真。应用Arena仿真克服了理论建模方法的不足,为物流中心最优站台数问题提供了一种较为理想的解决方法。     

供应链环境下的成本管理研究

本文就供应链环境下成本管理问题展开研究。文章认为在供应链环境中,管理者面临着更加复杂的成本问题,这就要求我们整合传统的成本管理框架,拓展成本管理的视野。为此,本文阐述了基于供应链模式下的成本管理目标、影响成本管理维度、成本管理方法和成本管理组织机构设立等等方面内容。说明成本管理目标是提升整个供应链的竞争力;影响成本管理维度的因素分别为产品、关系和资源;在供应链环境下作业成本法和链式目标成本是常常采用的成本方法。其次说明了柔性管理团队是供应链模式下成本管理目标实现的组织保证。     

第三方物流管理系统设计

物流管理软件在我国市场具有巨大的应用前景。由于我国企业的物流支出成本过高、管理水平落后，所以物流服务业市场潜力很大。物流管理软件的出现成为物流业发展的必然。然而，现在出现的各种物流管理软件很多存在自身的弊端和局限性。因此能设计出一个功能比较完备且经济、实用的物流管理系统迫在眉睫。本文主要对第三方物流管理系统的各种功能进行了论述和说明。
