【摘要】 高校教学质量评价是高校教学中的一个非常重要的环节。随着高校教学改革的不断深入，高校教学质量评价的手段和方法也在不断的完善，传统的教学质量评价方法已经不能完全满足目前高校教学质量评价的实际需求。学生通过计算机网络进行在线评教并由计算机程序汇总结果已经成为了国内外各个高校普遍采用的方法。但是由于教学质量评价的复杂性和教学评价目标的不确定性，使得很多计算机程序在处理教学质量评价时并不能尽如人意。论文研究了基于专家系统的思想来设计和开发高校教学质量评价系统，主要采用以专家系统为构架，借助模糊数学以及线性规划中的相关理论，利用知识库的思想对开发通用型实用教学质量评价系统进行了积极有益的尝试；在专家知识库的设计中，研究基于关系型数据库的专家知识库，利用关系数据库成熟的管理技术能够对知识库中的各种知识进行集中管理，可以方便地对这些知识进行增加、删除、修改、浏览等操作，增强了知识对技术人员的透明度；针对教学质量评价中的不确定性引入模糊数学的概念建立数学模型，采用模糊数学中的标准模糊划分理论，对评价域进行标准模糊划分；并对评价指标的权重用“德尔菲”法进行确定；构成模糊评价矩阵，利用综合加权法对评价矩阵进行汇总和推断，最后形成评价结论；并对模糊评价的模式进行了讨论；在系统的实现上，采用了面向对象的软件工程方法学，对系统的需求进行面向对象的分析和设计，最后进行黑盒测试，保证了系统的逻辑上的正确性，和使用的可靠性。目前该系统已经投入使用，实现了在校学生的网上评教和计算机推理生成评价结果，取得了良好的应用效果。更多还原

【Abstract】 College teaching quality evaluation is a most important part in the process of college education. With gradually development of college education ’s reformation, its ways and methods are improving and perfecting more and more, and traditional methods have not been fully met actual demands in the process of college education quality evaluation at present. That students evaluate education on line and computer programs reach results through the computer network has been adopted by various colleges and universities at home and abroad .But generally the method used, but because the complexity of evaluation of teaching quality and the uncertainty of evaluation goals, which makes it unsatisfactory when many computer programs evaluate teaching quality .This dissertation presents a system of high education quality evaluation which is designed and developed based on the idea of expert system. Expert system is employed as the architecture in the article. By way of related theories of fuzzy mathematics and linear programming and, with the idea of Knowledge Base, developing a general and practical teaching quality evaluation system is an active and useful attempt.This dissertation proposes that expert knowledge base be designed based on relational database, and knowledge be managed centralisedly in the knowledge base by the mature management technology in relational database in the process of the designation of expert knowledge base, which is convenient to add, delete, modify, browser, etc , and enhances knowledge transparency to technology people. Mathematical model is developed by the concept of fuzzy mathematics with regard to the uncertainly of teaching quality evaluation. Standard fuzzy partition is used in the evaluation domain with the theory of standard fuzzy partition of fuzzy mathematics. The weight of evaluation indicators is determined by Delphi Method so that a fuzzy evaluation matrix is constituted. Evaluation matrixes are summarized and inferred by the use of integrated weighted method and evaluation conclusions are reached at last. On the Implementation of the system, the object-oriented software engineering methodology is adopted. Object-oriented analysis and design are used for the system demands, and then the article tries to test black box testing, which guarantees that the system is right on the logistics and reliability on use.The system has been performed well which can realize evaluating education on network and yielding evaluation results.更多还原
