Mixed sampling plan based on exponentially weighted moving average statistic

ABSTRACT

We will design a new mixed acceptance sampling plan based on the exponentially weighted moving average statistic in this article. The plan parameters of the proposed plan are determined by an optimization problem. The efficiency of the proposed plan is compared with the existing attribute sampling plan. An industrial example is given for illustration purpose.     

A new proof of hsu's theorem in regression analysis– a coordinate-free approach

This paper provides a new proof of results by HSU (Statist. Res. Mem. 1938) and Drygas (Math. Operationsforsch. Statist. 1972) on estimating the variance σ²in HsU's regression model:By using a dispersion. mean-Correspondence the given problem in the theory of estimating the mean vector.     

Control charts for attributes with maxima nominated samples

We develop quality control charts for attributes using the maxima nomination sampling (MNS) method and compare them with the usual control charts based on simple random sampling (SRS) method, using average run length (ARL) performance, the required sample size in detecting quality improvement, and non-existence region for control limits. We study the effect of the sample size, the set size, and nonconformity proportion on the performance of MNS control charts using ARL curve. We show that MNS control chart can be used as a better benchmark for indicating quality improvement or quality deterioration relative to its SRS counterpart. We consider MNS charts from a cost perspective. We also develop MNS attribute control charts using randomized tests. A computer program is designed to determine the optimal control limits for an MNS p-chart such that, assuming known parameter values, the absolute deviation between the ARL and a specific nominal value is minimized. We provide good approximations for the optimal MNS control limits using regression analysis. Theoretical results are augmented with numerical evaluations. These show that MNS based control charts can yield substantial improvement over the usual control charts based on SRS.     

从人性假设视角透析管理思想回归的内在历史逻辑

本文试图在对管理思想历程做内在逻辑流变的完整把握、把管理思想的精髓和与现实经济生活的最新发展联系起来的基础上,追寻管理思想在时间维度上逐步人性化、在空间维度上由中方向西方再向中方回归的内在历史逻辑,以便为建立既源于古代管理思想又符合潮流的中国式管理理论体系提供整体指导。     

Attribute Control Chart for Multivariate Poisson Distribution

In this study, a control chart is constructed to monitor multivariate Poisson count data, called the MP chart. The control limits of the MP chart are developed by an exact probability method based on the sum of defects or non conformities for each quality characteristic. Numerical examples are used to illustrate the MP chart. The MP chart is evaluated by the average run length (ARL) in simulation. The result indicates that the MP chart is more appropriate than the Shewhart-type control chart when the correlation between variables exists.     

Performance Evaluation of Enterprise Knowledge Management based on Multiple Attribute Group Decision Making

Given that the classical performance evaluation models can not deal with the group decision making problems since they simply average the index, we propose an enterprise knowledge management evaluation model based on multiple attribute group decision making (MAGDM). Find the differences between Ordered Weighted Averaging (OWA) and meth- ods for uncertain decision making. Also, analyze the multiple attribute group decision making process and implement the al. gorithm. Finally, apply the method on performance evaluation of four enterprises and make sensitivity analysis towards the evaluation results.

Predictive design of single sampling attribute plans

The design of a sampling inspection plan is usually based on the properties of the operating characteristic curve. This approach ensures that the plan has adequate power to discriminate a lot of acceptable quality from a lot rejectable quality. However, the designed plan need not necessarily have adequate predictive power when the sentenced lot is re-inspected using the same sampling plan. The paper introduces a new design approach for the single sampling attributes plan ensuring the decision of acceptance or rejection is consistent for both current and any future inspection of the lot. The proposed design controls the risks of a future sample leading to a contradictory decision of acceptance or rejection of the lot. An increase in sample size is required to achieve the required predictive power if the true lot quality fails to be at very low fraction non-conforming levels. A Bayesian analysis is also provided.     

文学与人类学摭论

知识全球化推动了学科间的交叉与重组,促进了跨学科研究的快速发展;后现代主义和后殖民主义思潮的影响又引发了地方性知识和个体经验的崛起,这成为原本分属不同学科的文学与人类学不断融汇的社会根源。在中国和西方的双重语境下,采用宏观与微观、共时性与历时性的研究方法,构拟了文学与人类学的关系及走向:审美情感与田野实证是文学和人类学的属性差异;人学与生存经验是文学和人类学共同的精神向度;诗性思维与民族志互渗表征文学与人类学的相互转向;文学人类学是文学与人类学构建的新型研究范式。通过对文学与人类学的差异性、共通性、相互转向及学科共建的分析、阐释和论证,旨在厘清文学与人类学的关系及其走向,为文学研究和人类学研究提供方法论指导。
