信息产业发展水平综合评价体系研究

科学地分析信息产业发展水平是制定信息产业相关政策的重要基础。通过对信息产业发展阶段特征的综合分析,提出了一套科学的信息产业发展水平评价指标体系,运用层次分析法对评价指标进行综合分析,对国家信息产业发展水平作出了基本评价。通过对12个国家信息产业发展水平进行综合评价,对不同国家信息产业发展水平进行聚类分析,从而分析总结出信息产业各个发展层次的主要特征,为进一步制定信息产业发展的相关战略和政策提供了理论依据。     

基于多级模糊层次综合评价法的资源承载力研究

本文采用多级模糊层次综合评价法和聚类分析方法对全国30个省市区(不包括西藏、台湾、香港、澳门,下同)的资源承载能力进行了分析,对新疆资源承载力模糊综合评价结果和聚类分析结果进行了综合评价,指出了我国各省市区资源承载力的水平状态以及所处的位次和层次,探讨了各省市区资源承载力区际差异的主要原因。研究结果表明,各省市区间的资源承载力差别很大,东部经济发达的各省市资源承载力较高,显示出经济发展对资源承载力提升的互补性明显,西部经济落后的各省市区资源承载力较差,显示出其对自然资源承载力依赖度较高。     

The differences in hotel selection among various types of travellers: A comparative analysis with a useful bounded rationality behavioural decision support model

This study aims to investigate the hotel selection differences among different types of travellers through online hotel reviews. Specifically, the study performs a detailed examination of the differences in hotel key factors, criterion importance and selection results among five types of travellers, namely, business, couples, families, friends and solo. Using a sample of 194,885 online reviews on TripAdvisor.com, this study identifies the hotel key factors and criterion importance by employing the term frequency-inverse document frequency algorithm and Word2Vec algorithm. Additionally, a bounded rationality behavioural decision support model with picture fuzzy information is proposed to address hotel selection problems for different traveller types. Our results suggest that different types of travellers present differences in hotel key factors, criterion importance and selection results. However, families and friends have similar hotel selection results. This study can serve as a reference for hotel managers in understanding traveller preferences and for tourism website optimisation.     

中国城市竞争力与基础设施关系的实证研究

城市竞争力是城市产业创造价值的综合能力，提高城市竞争力必须清楚影响城市竞争力的关键因素，本文提出城市竞争力与基础设施竞争力关系的假说后，选取中国部分城市的样本指标数据，利用主成份分析方法，构造城市竞争力和基础设施竞争力指数，运用模糊曲线分析方法，对理论假说进行了初步的检验分析，结果显示：基础设施是城市竞争力最重要的成或影响力量，技术性基础设计对城市竞争力越来越至关重要。

《高等应用数学》定积分的教学探索

数学教学改革多年都流于形式,传统性强,权威性高,是问题所在。本人将传统16课时定积分教学,打破传统模式,改造成6课时教学,收到了很好的效果,现在拿出来与读者共享。     

气井产能的模糊综合评价

气井产能作为一个表示动态特征的参数,是气井评价的重要指标之一。依据测井数据进行产能评价,采用模糊数学中的模糊多目标决策综合评判建立了气井产能评价模型,通过对已分好类的气井建立贝叶斯判别函数,对其进行回判,并且通过实例进行验证,为气井产能评价方案提供了理论依据。     

项目组合选择研究：基于模糊理论的模型建构及验证

项目组合的选定与企业经营息息相关,然而传统的选择方法存在许多限制。本文应用模糊理论建构一个项目组合的决策模型,模型中纳入了成本、利润及风险等3个决策因子,探讨在资源有限的情况下项目成本及获利的交互影响关系,并利用模糊归属函数建构一个数学规划模型。为了验证模型的有效性,用此模型与传统模型进行求解比较,证实了所提出模型的实用性。     

Fuzzy Pair-wise Dominance and Implications for Technical Efficiency Performance Assessment

Classically, the concept of efficiency measurement is based on the definition of a frontier that envelops the observed production plans. The efficiency score itself is based on the distance of an observed production plan from this frontier. The frontier along with the required technological assumptions (such as convexity) needed for its definition may be replaced with the concept of pair-wise dominance. This concept leads to a classification scheme for all production plans instead of a ranking based on efficiency scores. Also, the traditional assumption of deterministic or crisp production plans may be substituted with the weaker assumption of fuzzy production plans as proposed by fuzzy set theory. This paper merges these two concepts and defines a new classification scheme based on fuzzy dominance.
