课程名称：《可靠性、可维修性与可用性导论》 课程概述： 本课程专注于项目经理和系统工程师可以采取的措施，以启动或提高系统的性能。课程涵盖了“为可靠性和可维护性设计”（Design for RM & A）及“可靠性和可维护性验证”（RM & A validation）活动，从系统开发者和最终用户的视角提供分析。此外，课程还涉及进行关键数学计算，这些计算对启动、规范和测试RM & A要求至关重要，包括如何使用RM & A计算来估计和提升系统的整体可用性。 在可靠性模块中，我们将探讨与识别、估计、计算和验证可靠性相关的核心原则。主题包括常用定义、生命周期分析、关于可靠性的误解、故障、故障模式和影响分析（FMEA）、故障率、生命数据分布、概率密度函数（如指数、对数、高斯和韦布尔分布）、可靠性估算、危害函数、平均故障间隔时间（MTBF）、平均故障时间（MTTF）以及“浴缸曲线”及其三个区域：设计故障率（DFR）、使用故障率（SFR）和老化故障率（IFR）。您将学习如何延长产品寿命、使用可靠性网络进行可靠性计算、应力和应变分析、故障树以及FMECA报告。 在可维修性模块中，主题包括定义、维修水平、FRACAS、正常运行时间（UT）、停机时间（DT）、平均修复时间（MTTR）、预防性和纠正性维护、维护频率、平均故障间隔时间（MTBM）、维修层级分析（LORA）、以可靠性为中心的维护（RCM）和基于状态的维护（CBM）、潜在功能失效（PF）、可维修性成本、预测和分配，以及可靠性和可维修性之间的权衡。 在可用性模块中，我们将运用所学的可靠性和可维护性知识，应用于可用性分析。同时覆盖三种主要的可用性类型：实现可用性（Aa）、固有可用性（Ai）和操作可用性（Ao）。课程在总结RM & A主题的基础上，形成一个整体的视角，主题包括RM & A挑战、RM & A起始值、可靠性和可维修性测试、RM & A的顺序测试与确认以及产品生命周期测试。
This course focuses on actions project Managers and Systems Engineers can take to initiate or improve the performance of their systems.This course covers both ‘design for RM & A' and ‘RM & A validation' activities to provide the viewpoints of the system developer and the end user.This course also covers the essential mathematical calculations that are essential to initiating, specifying and testing RM & A requirements, to and includes the application of how you can use RM & A calculations to estimate and improve your overall system's availability.In the Reliability Module, we will cover many core principles related to identifying, estimating, calculating and verifying reliability related requirements and models. Topics include common definitions, lifecycle analysis, reliability myths, failures, Failure Modes and Effects Analysis (FMEA), failure rates, life data distributions, probability density functions; exponential, logarithmic, gaussian, and Weibull distributions; reliability estimates, the hazard function, MTBF, MTTF, the "bathtub curve" and its 3 regions: DFR, SFR and IFR. You'll learn about extending a product's life, reliability calculations using reliability networks, stress and strain analysis, fault trees and FMECA reporting.In the Maintainability Module, topics include definitions, maintenance levels, FRACAS, Uptime (UT), Downtime (DT), MTTR, preventive and corrective maintenance, maintenance frequency, MTBM, Level Of Repair Analysis (LORA), Reliability Centered Maintenance (RCM) and Condition-Based Maintenance (CBM), Potential to Functional failures (PF), Maintainability cost, prediction, and allocation, and trade-offs between reliability and maintainability.In the Availability Module, we use what we learned about R & M and apply it to availability. We also cover the three primary types of availability: Achieved Availability (Aa), Inherent Availability (Ai) and Operational Availability (Ao).The course concludes by consolidating RM & A topics into a holistic picture. Topics include RM & A challenges, RM & A starting values, testing for reliability & maintainability, RM & A sequential testing and qualification and product life testing.
