对于可修复产品，无故障工作期（FFOP）与无维修工作期（MFOP）存在紧密联系。依据泊松理论，故障率函数具有浴盆曲线特征的故障发生过程需要用非齐次泊松过程进行描述。首先介绍了FFOP的概念及其国内外技术发展历程；继而，利用基于修正的Weibull分布函数构建的浴盆曲线故障率函数，对故障率具有浴盆曲线特征的装备提出了FFOP预计方法，并通过案例说明了预计方法的可行性。最后，分析了装备FFOP与基于MFOP的装备维修策略的关系，认为装备FFOP的确定应综合权衡可靠性/安全性和维护成本。
對于可脩複產品，無故障工作期（FFOP）與無維脩工作期（MFOP）存在緊密聯繫。依據泊鬆理論，故障率函數具有浴盆麯線特徵的故障髮生過程需要用非齊次泊鬆過程進行描述。首先介紹瞭FFOP的概唸及其國內外技術髮展歷程；繼而，利用基于脩正的Weibull分佈函數構建的浴盆麯線故障率函數，對故障率具有浴盆麯線特徵的裝備提齣瞭FFOP預計方法，併通過案例說明瞭預計方法的可行性。最後，分析瞭裝備FFOP與基于MFOP的裝備維脩策略的關繫，認為裝備FFOP的確定應綜閤權衡可靠性/安全性和維護成本。

Failure Free Operating Period (FFOP)was connected with Maintenance Free Operating Period (MFOP) compactly towards the repairable product. The failure event of the arm should be modeled with inhomogeneous Poisson process,whose failure rate function is shaped like a bathtub curve. Firstly,the concept and the technology developing course of FFOP are introduced. Then,the FFOP prediction process is developed by the bathtub shaped failure rate function which is modeled based on modified Weibull distribution function. The accuracy of method is verified through case. Furthermore,the relationship between FFOP and maintenance strategy based on MFOP is illustrated. FFOP should be decided by weighing up reliability/safety and maintenance cost.
