As used here, reliability is a measure of the frequency of equipment failures as a function of time. Reliability has a major impact on maintenance and repair costs and on the continuity of service. 可靠性预计是一个重要的因素在选择设备使用的电信服务供应商和其他买家的 电子设备。用在这里，可信度是测量频率的设备故障作为时间函数。可靠性有重 大影响在保养和维修成本和服务的连续性。 The purpose of this RPP is to document recommended methods for predicting device and unit hardware reliability. This procedure also documents a recommended method for predicting serial system hardware reliability. It contains instructions for suppliers to follow when providing predictions of their device, unit, or serial system reliability (hereinafter called “product” reliability). It also can be used directly by telecommunications service providers for product reliability evaluation. 这样做的目的是比较文件的推荐方法和装置硬件的可靠性预测装置。本程序文件 推荐方法的串行系统硬件的可靠性预测。包含对供应商提供的设备时，单位的预 测说明，或串联系统的可靠性（以下称为“产品”可靠性）。它也可以直接使用 仅供学习交流，勿做商用，文中翻译缺陷请联系我。 的电信服务供应商的产品可靠性评估。 Device and unit failure rate predictions generated using this procedure are applicable for commercial electronic products whose physical design, manufacture, installation, and reliability assurance practices meet the appropriate Telcordia (or equivalent) generic and product-specific requirements. 使用此程序适用于商用电子产品的物理设计，制造，安装发电装置和机组的故障 率预测，和可靠性保证措施满足适当的 Telcordia （或同等）通用和特定产品的要 求。 This procedure
