电子工业协会（EIA）G-47效能量化委员会的一项基本任务是量化系统效能。由于支持参数是任何基本参数量化的基础，因此支持系统分析是委员会这项基本任务的一个基本主题。本公告中包含的图表已编制完成，并用于向飞机保障工程组进行演示，以传达应用于保障系统优化的系统分析的逻辑和范围。

The Electronic Industries Association (EIA) G-47 Effectiveness QuantificationCommittee has a basic task to quantify system effectiveness. Since the support parameters underly any prime parameter quantification, the topic of support system analysis is a fundamental one to this basic committee task.The charts contained in this bulletin were developed and used for presentations to aircraft support engineering groups, to comunicate the logic and scope of system analysis applied to support system optimization.
