负荷分担系统有几个实际应用。在负载共享系统中，组件故障的事件将导致更高的负载，从而导致每个幸存组件的更高故障率。这在负载共享组件之间引入了故障依赖，从而增加了分析这些系统的复杂性。在本章中，我们首先讨论了负荷共享系统可靠性分析的建模方法和现有的求解方法。然后，我们描述了篡改故障率（TFR）负载共享系统及其性质。利用这些特性，我们为求解TFR负荷共享模型提供了有效的求解方法。由于负载分担系统在可靠性工程中有许多实际应用，我们对这些系统的各种情况进行了详细的分析。本章提出的求解方法适用于相同和非相同部件的情况。所提出的方法不局限于指数型失效分布，适用于大范围的部件失效时间分布。在大多数情况下，我们为TFR负荷分担系统的可靠性提供了封闭形式的分析解决方案。作为一种特殊情况，提供了具有相同组件的系统的有效解决方案，其中所有幸存的组件平均分担负载。通过几个数值算例验证了所提方法的有效性。
Load-sharing systems have several practical applications. In load-sharing systems, the event of a component failure will result in a higher load, therefore inducing a higher failure rate, in each of the surviving components. This introduces failure dependency among the load-sharing components, which in turn increases the complexity in analyzing these systems. In this chapter, we first discuss modeling approaches and existing solution methods for analyzing the reliability of load-sharing systems. We then describe tampered failure rate (TFR) load-sharing systems and their properties. Using these properties, we provide efficient solution methods for solving TFR load-sharing models. Because load-sharingk-out-of-nsystems have several practical applications in reliability engineering, we provide a detailed analysis for various cases of these systems. The solution methods proposed in this chapter are applicable for both identical and non-identical component cases. The proposed methods are not restricted to the exponential failure distributions and are applicable for a wide range of failure time distributions of the components. In most cases, we provide closed-form analytical solutions for the reliability of TFR load-sharingk-out-ofn: G systems. As a special case, efficient solutions are provided for systems with identical components where all surviving components share the load equally. The efficiencies of the proposed methods are demonstrated through several numerical examples.
