故障预测的任务要求预测即将发生的故障。本技术说明阐述并研究了离散事件系统的分布式预测问题，其中本地预测者为了达到预测决策而交换他们的观察结果。通过引入有界延迟的通信信道交换观测。引入了联合可预测性的一个属性来描述任何故障在其发生之前都可以由某个局部预测器预测的条件。我们提供了一个算法来检查联合可扩展性属性。
The task of failure prognosis requires the prediction of impending failures. This technical note formulates and studies the problem of distributed prognosis of discrete event systems, where the local prognosers exchange their observations for the sake of arriving at a prognostic decision. The observations are exchanged over communication channels that introduce bounded delays. A property of joint-prognosability is introduced to capture the condition under which any failure can be predicted by some local prognoser prior to its occurrence. We provide an algorithm to check the joint-prognosability property.
