基于ELM的英语教学质量评价研究

对英语教学质量实施科学化的评价关系到英语教学质量的提升,为减少主观因素的影响,本文提出一种ELM的教学质量评价方法,该种方法将可以在很大程度上提高教学质量评价的精度。对影响英语教学质量的12个指标进行打分,以此作为ELM的输入,同时将英语教学质量的综合得分作为ELM的输出。评价结果表明,基于EIM的英语教学质量评价结果比SVM、BP具有了很大程度的提升,为实施英语教学质量的评价提供了参考。     

基于AHP和模糊数学的建筑节能性能评估

巴渝庄园建筑防御特色研究——以重庆涪陵石龙井庄园为例

探析巴渝庄园建筑的防御效能,对于研究巴渝防御型民居建筑发展具有重要意义,可用于比较同一地区不同历史时期同一类型建筑防御效能的变化,也可用于对比同一时期不同地区同一类型建筑防御效能的差异。文章对重庆涪陵区石龙井庄园的防御性能进行定性分析的同时,采用层次分析(AHP)法和模糊综合评判法集成进行定量评价,以此探析巴渝地区的庄园建筑防御特色。     

The sociotechnical constitution of cognitive work analysis: roles,affordances and malfunctions

Analysis of everyday work practices in sociotechnical systems for eliciting design/intervention requirements involves appropriate work analysis frameworks. The current article provides an extension to one such framework — Cognitive Work Analysis (CWA) — by scrutinising its sociotechnical basis. CWA's forte depends on its ‘design for adaptation’, system related operations, and operators. In contrast, sociotechnical work systems require not only operators and adaptation, but also a significant emphasis on ‘users’ and ‘appropriation’. The current article extends CWA (based on Rasmussen's original concepts) for users; subsequently allowing for system flexibility and possibilities of ‘appropriation’ within acceptable boundaries of the system's correct functioning. To this end, the first phase of Work Domain Analysis is extended by adding a new layer to the abstraction hierarchy (AH), based on Rasmussen's original insights.     

AHP-模糊综合评价法在标准实施效果评价中的应用

开展标准实施效果评价能够对标准的实施状况、标准的科学性有一个客观和科学的认识,对标准的制修订工作有重要的指导意义。本文以石油工业标准为研究对象,从标准实施状况、标准实施监督、标准经济效益和标准社会效益4个方面构建了评价体系,综合运用层次分析法(AHP)和模糊综合评价法对标准实施效果进行评价。评价结果表明,该方法可以实现定性分析和定量分析的有效结合,使评价结果更符合实际情况,为标准实施效果评价提供了一种新的思路。     

基于组合赋权-集对分析的煤矿煤尘爆炸危险性评价研究

针对目前煤尘爆炸危险性评价研究较少、各评价因素选择偏差较大的问题,通过分析煤尘爆炸特性,提出以煤尘可爆性危险、煤尘爆炸浓度危险、点火源危险3个必要条件为一级指标,煤质变异程度、挥发分、水分、灰分等14个二级指标,以层次分析法确定各指标的主观权重,以熵权法确定各指标的客观权重,利用乘法归一化方法对各指标的组合权重进行计算,构建集对分析-组合赋权煤尘爆炸危险性评价模型,并将该模型与已较成熟的改进FAHP模型、模糊事故树模型、灰色聚类评估体系、未确知测度评价模型一同应用于济宁某矿的煤尘爆炸危险性评价过程中,结果显示:集对分析-组合赋权评价模型、改进FAHP模型、灰色聚类评估体系评价结果为一般危险等级,模糊事故树模型的评价结果为较安全等级,集对分析-组合赋权煤尘爆炸危险性评价模型评价结果与改进FAHP模型、灰色聚类评估体系、未确知测度评价模型的评价结果一致,该模型对煤尘爆炸危险的评价具有较好的适用性。     

煤层底板突水危险性分析：以唐山市钱家营矿12煤层底板为例

唐山市钱家营矿地处开平向斜南东翼,地质条件复杂,为探究钱家营矿12煤层底板突水危险性,基于矿井钻孔与水文地质资料,选取钱家营矿12煤层底板受奥灰水水压、隔水层厚度、有效脆性岩层厚度以及断层与褶皱分布作为影响钱家营矿12煤层底板突水的主控地质因素,运用层次分析法对各主控因素进行评价、构造判断矩阵、计算各主控因素所占权重、引入危险性评价模型并为所得数据选取合理的界限值,最终得到钱家营矿12煤层底板突水危险性评价分区图。研究表明:钱家营矿12煤层底板突水可能性较大,尤其是构造较为发育的东北地区,对比矿井水文地质资料,评价结果与实际拟合较好。本次研究为有效防治煤层底板水害提供了理论与技术支持。     

Multiple integral inequalities and stability analysis of time delay systems

This paper is devoted to stability analysis of continuous-time delay systems based on a set of Lyapunov–Krasovskii functionals. New multiple integral inequalities are derived that involve the famous Jensen’s and Wirtinger’s inequalities, as well as the recently presented Bessel–Legendre inequalities of Seuret and Gouaisbaut (2015) and the Wirtinger-based multiple-integral inequalities of Park et al. (2015) and Lee et al. (2015). The present paper aims at showing that the proposed set of sufficient stability conditions can be arranged into a bidirectional hierarchy of LMIs establishing a rigorous theoretical basis for comparison of conservatism of the investigated methods. Numerical examples illustrate the efficiency of the method.     

Promotion Routes for Women Engineering Managers

ABSTRACT

Total quality management (TQM) has been increasingly accepted as a management philosophy. Criteria such as those contained in the Malcolm Baldrige National Quality Award (MBNQA) often guide TQM implementation. However, reports indicate that fully assessing TQM efforts is difficult and hiring experts to help with this task is expensive. Using survey instruments is an attractive alternative to full-scale assessment. Despite the availability of many papers covering organizational performance assessment, few instruments specifically address TQM evaluation. Furthermore, none of the TQM assessment instruments has been subjected to rigorous validation; thus, only modest confidence can be placed in results obtained from their use. This article proposes a quick and cost-effective instrument that is a simple questionnaire designed to assist organizations in conducting self-evaluations of their TQM programs. The proposed instrument is based on the seven categories of the MBNQA criteria and was developed in cooperation with the Excellence in Missouri Foundation, which administers the Missouri Quality Award (MQA). This article highlights how questionnaire results can be used to guide further TQM implementation efforts.
