试论高校图书馆采访模式的多元化

在数字化时代,传统的文献采访模式面临着新的挑战,高校读者群的个性化需求日益强烈,采访人员应吸时更新理念,以多元化的文献采访模式构建起更为科学、合理、适用的馆藏文献资源。     

Inspection-replacement policy of system under predictive maintenance

In general, every system is in one of the three states: normal, abnormal, or failure state. When the system is diagnosed as abnormal state, it needs predictive maintenance. If the system fails, an identical new one will replace it. The predictive main- tenance cannot make the system “as good as new”. Under these assumptions, the reliability index and the inspection-replacement policy of a system were studied. The explicit expression of the reliability index and the average income rate (i.e., the long-run average income per unit time) are derived by using probability analysis and vector Markov process method. The criterion of feasibility for the optimal inspection-replacement policy under the maximum average income rate is obtained. The numerical example shows the optimal inspection-replacement policy can raise the average income rate when the optimal inspec- tion-replacement policy is feasible.

Preventive repair policy and replacement policy of repairable system taking non-zero preventive repair time

The repairable system with preventive maintenance is one of the typical systems with wide useful applications in engineering. If the system can be made as good as new by preventive maintenance, both the life stochastic variable of different periods and fault correction time stochastic variable form monotonous stochastic process. Based on the above assumption and the available results, in this paper we discuss the maintenance and replacement policy of the repairable system with preventive maintenance. The intervals of preventive maintenance, T, and the times of system failure, N, are introduced and the vector Markov process method is used. The formulation of steady state average profit rate can be deduced to solve the optimization problem of the maintenance and replacement policy.     

《数据库应用》课程体系建设研究

《数据库应甩》是信息管理与信息系统专业的核心课程,课程目标是让学生了解数据库的设计方法,学会delphi7.0程序设计,掌握关系型数据库管理系统(DBMS)的具体应用,获得用delphi7.0开发数据库应用系统的能力.围绕课程目标,在课程改革过程中,通过对课程自身结构体系的分析,形成“一般知识点的分解型任务”教学法,满足教学大纲对基本知识点的考察.通过对课程所属课程群结构体系的建构,为“开放式小组项目”教学法的形成提供了知识准备,这种方法培养了学生创新意识,提高了学生的自主创新能力.     

高职校园文化建设实践与思考

主要阐述了校园文化内涵,校园文化也是学校在长期办学过程中积淀的物质、精神文化产物。高职院校的校园文化具有鲜明的特色,从内涵到建设都应以职业教育为基点,突显企业文化与高校文化的融合,营造一个培养职业人的良好氛围,对高职校园文化不断探索、积累和凝练。     

"兼爱":构建和谐社会的道德基础

“兼爱”是墨家思想体系的核心内容,所谓“兼爱”,意是整体的爱、平等的爱,人与人平等相爱,不能有人、己、亲、疏的区别。“兼爱”思想恰是商品经济社会生产和消费活动的伦理原则,有兼爱之心,使利己心(爱己)与利他心(爱人)之间的平衡,这是市场经济活动中的利益主体取得双赢、多赢所应当遵循的道德原则,也是现阶段社会走向和谐的道德需求。     

基于DEA的地方政府逆向物流管理绩效研究

运用一种多指标输入/输出复杂系统的相对有效性评价方法——数据包络分析法(DEA)对地方政府逆向物流管理绩效进行评价,根据评价结果分析存在的问题并提出相应的解决措施。最后通过算例说明DEA方法是适合于地方政府逆向物流绩效评价的。
