试论徽州谱牒的体与魂

徽州谱牒是中国谱牒的重要组成部分。宋代欧阳修、苏洵创立的五世图式体例,构成徽州谱牒的基本框架,可谓之徽州谱牒之体;南宋朱熹的理学思想,成为徽州谱牒的精神支柱,可谓之徽州谱牒之魂。深入解剖徽州谱牒这一基本模式,有助于整理、开发、研究数以万计的中国谐牒这份珍贵的历史文化遗产,使其在弘扬中华历史文化,提高中华民族精神,增强中华民族凝聚力和向心力,进而对促进实现祖国和平统一大业起到积极作用。

EWMA control charts for monitoring correlated counts with finite range

In this work, we develop and study upper and lower one-sided EWMA control charts for monitoring correlated counts with finite range. Often in practice, data of that kind can be adequately described by a first-order binomial or beta-binomial autoregressive model. Especially, when there is evidence that data demonstrate extra-binomial variation, the latter model is preferable than the former. The proposed charts can be used for detecting upward or downward shifts in process mean level. Practical guidelines concerning the statistical design of the proposed charts are given, while the effect of the extra-binomial variation is investigated as well. Comparisons with existing control charting procedures are also provided. Finally, an illustrative real-data example is also given.     

A binomial CUSUM chart for detecting large shifts in fraction nonconforming

This article studies a unique feature of the binomial CUSUM chart in which the difference (d _t ?d ₀) is replaced by (d _t ?d ₀)² in the formulation of the cumulative sum C _t (where d _t and d ₀ are the actual and in-control numbers of nonconforming units, respectively, in a sample). Performance studies are reported and the results reveal that this new feature is able to increase the detection effectiveness when fraction nonconforming p becomes three to four times as large as the in-control value p ₀. The design of the new binomial CUSUM chart is presented along with the calculation of the in-control and out-of-control Average Run Lengths (ARL₀ and ARL₁).     

Parameter estimation and design considerations in prospective applications of the � chart

The effects of parameter estimation on the in-control performance of the Shewhart X¯ chart are studied in prospective (phase 2 or stage 2) applications via a thorough examination of the attained false alarm rate (AFAR), the conditional false alarm rate (CFAR), the conditional and the unconditional run-length distributions, some run-length characteristics such as the ARL, the conditional ARL (CARL), some selected percentiles including the median, and cumulative run-length probabilities. The examination involves both numerical evaluations and graphical displays. The effects of parameter estimation need to be accounted for in designing the chart. To this end, as an application of the exact formulations, chart constants are provided for a specified in-control average run-length of 370 and 500 for a number of subgroups and subgroup sizes. These will be useful in the implementation of the X¯ chart in practice.

两个系统因素影响下的联合动态均值图

本文研究了两个系统因素下过程控制中样本容量和抽样区间的联合动态均值图（VSSI）,并利用马氏链方法研究了动态均值图的性质。结果表明：VSSI图比VSS图,VSI图及FSSI图能更快地发现过程均值的漂移,因此,VSSI图对于快速检测遭受不同类型系统因素的过程更加有效,且对均值的敏感性增加,最后给出了联合动态均值图在生产中的一个应用实例。
