摘要

在工程实践中，分阶段任务系统(pms)可能存在相位冗余。失败的任务不仅可以在当前阶段执行，还可以在其冗余阶段执行。因此，与一般PMS系统不同，具有相位冗余的PMS系统具有多个任务执行序列。考虑到系统的复杂性，人工建模容易出错。因此，需要某种工具来支持建模过程。提出了一种基于系统建模语言(SysML)的PMS-PR规范模型。最后，以一个简化的PMS-PR为例，说明了规范模型的建模过程。

A Specification for Phased-mission System with Redundancy Based on SysML

In engineering practice, phased mission systems (PMSs) may have phase redundancies. A failed task can be executed not only in the current phase, but also in its redundancy phases. Therefore, different from general PMSs, a PMS with phase redundancy (PMS-PR) has several mission execution sequences. Considering the complexity of the system, it is easy to make mistakes by manual modelling. Therefore, a certain tool is needed to support the modeling process. This paper proposes a specification model of PMS-PR based on system modeling language (SysML). Finally, a simplified PMS-PR is illustrated as an example to show the modeling process of the specification model.
