RAM分析技术是针对可靠性、可用性和可维修性三个要素的量化技术，可用于评估系统中设备的关键性，确定最佳的冗余设置方法，提高完整性管理水平，为确定投资成本和运行成本提供参考。在伊朗雅达油田地面工程设计中，采用PLASMA软件，基于蒙特卡洛方法和马尔科夫模型，对油气分离装置和中央处理站的备选方案开展了RAM研究。经过分析范围定义、失效与维修分析和敏感性分析等步骤，得到了各方案的可用度和各子系统的关键性，为设计方案的完善提供了有效的技术支撑。RAM分析在本例中的作用和优势可为国内地面工程技术人员提供参考。%RAM analysis technique is a quantization technique focused on the reliability, availability and maintainability of a system. It can be adopted to evaluate the criticality of fa-cilities in the system,determine the optimal redundancy setting scheme,improve the level of integrity management, and provide reference for the determination of CAPEX and OPEX. In the design of facility engineering in Iran Yadavaran oilfield, PLASMA software is adopted to conduct the RAM analysis on the design options of GOSU and CTEP, based on the Monte Carlo approach and Markov model. Through the analysis procedures, including scope definition,failure and repair data analysis and sensitivity analysis,availability of the op-tions and criticality of the subsystems are obtained, which provide effective technical supports for the improvement of the design options. It is expected that the function and advantages of RAM in this example could provide some reference for the domestic surface facility engineers.
