为了控制离散事件系统（DES），监督控制器观察事件序列。可观测性，连同可控性，需要通过监督控制获得精确的规范语言。通过扩展可观测性，最近研究了相对可观测性。本文定义了网络的相对能观度，它包含了相对能观度中的观测不完全性和时滞。提出了一种将网络相对可观性转化为网络可观性的算法。这利用现有的解决方案来解决有关网络可观测性的问题，以解决有关相对网络可观测性的问题。特别是，我们提出了检查相对网络的可观测性和计算最高可控和相对网络可观测的子语言的技术。
In order to control a discrete-event system (DES), the supervisory controller observes event sequences. Observability, together with controllability, is required for obtaining the exact specification language via supervisory control. By extending observability, relative observability was recently investigated. In this article, relative network observability, which accommodates observation incompleteness and delay in relative observability, is defined. An algorithm is proposed to transform relative network observability to network observability. This leverages existing solutions to problems concerning network observability to solve problems concerning relative network observability. In particular, we propose techniques for checking relative network observability and calculating supremal controllable and relatively network observable sublanguage.
