| 中文摘要: |
| 针对巧克力食品制造企业生产线设备维护体系不健全、设备管理效率低等缺点，建立了基于故障树分析法（fault tree analysis，FTA)、失效模式和影响分析(failure mode and effect analysis，FMEA)以及威布尔分布改进方法的巧克力生产线专用设备管理状态维护方法和模块。以某巧克力生产企业F公司的榛子巧克力球生产线设备管理为研究对象，利用FTA FMEA对生产线设备关键失效模式进行筛选识别；结合贝叶斯规则优化威布尔分布，并提出组件实时可靠度函数；在SAP PM通用模块的基础上，建立了专用设备管理模块，介绍了主要功能模块的工作流程及原理。应用结果表明提出的设备状态维护方法不仅可以提高设备维修的反应速度，且可有效提高食品制造企业设备管理水平。课题组研究的专用设备管理模块能减少故障损失，延长设备使用寿命。 |

| Aiming at the shortcomings of the equipment maintenance system of food enterprises, such as imperfect maintenance system and low efficiency of equipment management, a special equipment management module of Chocolate production line was established based on fault tree analysis(FTA), failure mode and effect analysis(FMEA) and improved Weibull distribution method. The equipment management of hazelnut chocolate ball production line of company F was taken as the research object. FTA FMEA was used to identify and screen the critical failure mode of production line equipment. The Weibull distribution was optimized with Bayes rule, and the component real time reliability function was proposed. On the basis of SAP PM general module, a special equipment management module was established, and its main functions and workflows were introduced. The application results show that the dedicated equipment management module can not only improve the response speed of equipment maintenance, but also effectively improve the equipment management level of food enterprises. This special equipment management module can reduce the failure loss and extend the service life of the equipment. |
