本文从电子产品生产统计实例出发,论述了随机概率在电子产品生产统计中应用的局限性和片面性,指出只有利用模糊数学才能克服上述片面性。同时也能指导产品的合格率的提高。因此,本文具有较大的实用价值。另外,本文把设计、备件和生产三方面因素有机地结合在一起,处理了电子技术中过去加以忽略的模糊概念,模糊事件。所以本文在电于技术中也有一定的理论价值。 Based on the statistical examples of electronic product production, this paper discusses the limitation and the one-sidedness of the application of stochastic probability in the production statistics of electronic products, and points out that only the use of fuzzy mathematics can overcome the above-mentioned one-sidedness. At the same time can also guide the improvement of product qualification rate. Therefore, this article has greater practical value. In addition, this article organically combines design, spare parts and production in three aspects, dealing with the fuzzy concepts and fuzzy events that were neglected in the past in electronic technology. Therefore, this paper also has some theoretical value in electric technology.
