门座起重机RCM维修决策系统设计

RCM-based maintenance decision-making system design for portal crane

应用面向对象高级语言C#和SQL Server 2005数据库,采用风险矩阵法、模糊层次分析法、根本原因分析法、综合决策法、逻辑决策法等方法,开发一套基于RCM技术,能够完成港口门座起重机的基础信息管理,以风险为基础,具有良好目标性的维修决策系统,根据用户选择的影响因素来确定其零部件的维修方式和最佳维修周期,以提高机械设备的可靠性和安全性,为企业提供优化、系统、科学的维修决策支持。

Using object-oriented high-level language C # and SQL Server 2005 database,adopting risk matrix method,fuzzy analytic hierarchy process,root cause analysis,integrated decision-making method and logical decision methods,a maintenance decision-making system for portal crane based on reliability centred maintenance（ RCM） technology and risk-analysis was developed. The system can implement the basic information management of portal crane,which is based on risk analysis and can realize targeted maintenance decision-making. The system can determine the repair method and best maintenance period of components based on the factors influencing users,the selection to improve the reliability and safety of machinery and equipment,and provide minimum downtime optimization,systematic and scientific maintenance decision support.
