摘要: 模糊数学是一门崭新的数学学科,而且是计算机科学向人类的自然机理方面发展的重大突破。网格是近十年来信息技术领域的热点研究课题。本文将模糊数学的理论知识用于网格信任模型、服务质量等级的判断上,使得用户信任度的评估更加准确、灵活、可靠。模糊语言变量是一种既能反应信任的模糊性又具有直观简洁特点的定量描述机制。它能够很好地描述网格的动态特性,为网格的信任模型发展提供理论支持。

Abstract: Fuzzy mathematics is a brandnew subject of mathematics. Additionally, it is a great breakthrough from the science of computer to the mechanism of physical science for human being. The grid is regarded as the hottest topic in the research of information and technology area for several decades. The paper uses fuzzy mathematics as a tool to evaluate the trust model and the grade of service quality, which makes the assess of users trust values become more accurate, flexible and reliable. Fuzzy language variable is a quantitative, descriptive model which can describe the fuzzy character of trust and show the characteristic of itselfintuition and concision. It also can depict the dynamic quality of the grid and promote the development trust model of the grid in the theory.

Key words: grid, grid trust model, fuzzy mathematics
