模糊故障树分析方法在HACCP中的应用研究

Application of the fuzzy fault tree analysis approach to HACCP system

摘要: 危害分析与关键控制点(HACCP)是一个复杂的系统工程，对于农产品加工企业或食品企业而言，制定一个产品的HACCP计划有很大的难度，特别是对于关键控制点的正确选取更需要领域专家的帮助。该文介绍了故障树分析方法在HACCP体系第一原则和第二原则上的应用，并引入模糊数学理论中的模糊算法和非模糊化方法与故障树分析方法相结合，分别适用于计划的制定和计划的变更，并可根据该方法开发出制定计划的软件工具，使得计划的制定趋于简单化和自动化。

Abstract: The practical implementation of Hazard Analysis and Critical Control Point(HACCP) in particular the definition of the Critical Control Points(CCPs) in the food industry is usually a complex system engineering. The application of Fault Tree Analysis(FTA) approach to the first and second principles of HACCP was recommended. Combined the fuzzy arithmetic and defuzzification with FTA, HACCP plans were created and updated. A software tool will be developed based on the approach introduced, aimed at simplification and automation of the hazard analysis.
