摘要
计算机可靠性与其产品的环境适应能力和工作条件紧密相关 .对产品工作条件描述的模糊性 ,对环境适应能力描述的概略性 ,是考虑环境因素的可靠性评价最大的困难 .采用云模型将不确定的工作条件和概略性的环境适应能力描述映射为可细微变化的不同云滴 ,实现定性和定量的合理转换 ,并在此基础上 ,提出一种新的考虑环境因素影响的可靠性评价方法 。
The reliability of computers is tightly related to its suitability and its working conditions. Because the working conditions are usually described by qualitative, fuzzy words, and the suitability is usually described with only a outline, it's difficult to evaluate the reliability count for the effects of environmental factors. By mapping qualitative linguistic suitability word into quantitative values and translating the uncertainty working conditions into a fine changeable variable drops using cloud models, a new evaluating way is proposed taking suitability and working conditions into account. It may solve the reliability evaluation problems of military computers working in changeable conditions.
