Abstract In this study, failure mode and effect analysis were applied to evaluate and eliminate potential failure modes in a Ready-Mixed Concrete Plant using a fuzzy-rule-base system. The questionnaires were specially prepared for each sub-department such as production plant, workshop and maintenance, dumping grounds, materials transportation and storage, utilities, administrative office, social facility, quality control laboratory and wastewater pool and recycling facilities. The questions were answered by the workers in each section. Risk Priority Numbers (RPNs) and Fuzzy Risk Priority Numbers (FRPN), which measure potential failure modes, were calculated using the risk parameters. High-risk areas were identified, and some suggestions were made to reduce accident risk at the Ready-Mixed Concrete Plant. Three questionnaires were prepared, based on these suggestions, and distributed to workers to determine whether the suggestions would reduce the risk or not. Based on conditions at the time the recommendations were implemented and improvement rates were calculated. The results showed that the fuzzy failure mode and effect analysis methodology were effective in identifying and eliminating potential failure modes at the Ready-Mixed Concrete Plant. The results can also be used by other ready-mixed concrete manufacturers who want to improve the safety of their operations.

降低预拌混凝土厂风险水平的模糊失效模式和影响分析应用：一种基于模糊规则的系统建模方法

摘要 在这项研究中，失效模式和影响分析被用于评估和消除使用模糊规则库系统的预拌混凝土厂的潜在失效模式。问卷专门针对生产厂、车间和维修、倾倒场、材料运输和储存、公用事业、行政办公室、社会设施、质量控制实验室和废水池和回收设施等各个子部门准备。各部门的工作人员对问题进行了解答。测量潜在故障模式的风险优先级数 (RPN) 和模糊风险优先级数 (FRPN) 是使用风险参数计算的。确定了高风险区域，并提出了一些降低预拌混凝土厂事故风险的建议。准备了三份问卷，基于这些建议，并分发给工人以确定这些建议是否会降低风险。根据实施建议时的情况并计算改进率。结果表明，模糊失效模式和影响分析方法可有效识别和消除预拌混凝土厂的潜在失效模式。其他想要提高操作安全性的预拌混凝土制造商也可以使用这些结果。结果表明，模糊失效模式和影响分析方法可有效识别和消除预拌混凝土厂的潜在失效模式。其他想要提高操作安全性的预拌混凝土制造商也可以使用这些结果。结果表明，模糊失效模式和影响分析方法可有效识别和消除预拌混凝土厂的潜在失效模式。其他想要提高操作安全性的预拌混凝土制造商也可以使用这些结果。
