Abstract: Operators and plant computer programs used to operate a complex process facility are aided in managing the process during transitions by a computer-based apparatus. The apparatus incorporates a knowledge base and methods for identifying modes and transitions during plant operation. At frequent intervals, measured values of the process variables are used to evaluate the current state of the process and its sections and subsections. The identified state of the plant is broadcast to different clients of this application. The apparatus monitors the plant for the normal execution of the transition. It also identifies the current task being performed in the process and sends this message to different sections of the plant. The results are displayed on a visual display device and can also be sent to other plant computer programs for guidance during the transition. A permanent chronological record of the sequence of events—modes and transitions—of the plant and sections and subsections including the pertinent plant conditions and information is also generated by the apparatus for subsequent review and analysis. Methods for generating the knowledge base are also presented.

Abstract: A method for identifying modes and transitions during plant operation, wherein measured values of process variables are used to evaluate a current state of the process and its sections and subsections. An identified state of the plant is signaled and the plant is monitored for normal execution of any transition, identifying a current task being performed in the process and sending a message to different sections of the plant. Results are displayed on a visual display device and can be sent to other plant computer programs for guidance during the transition. A permanent chronological record of the sequence of events—modes and transitions—of the plant and sections and subsections including the pertinent plant conditions and information is generated for subsequent review and analysis.

Abstract translation: 用于在工厂操作期间识别模式和转换的方法，其中使用过程变量的测量值来评估过程及其部分和子部分的当前状态。 通过信号通知工厂的识别状态，并监视工厂正常执行任何转换，识别正在执行的当前任务并向工厂的不同部分发送消息。 结果显示在视觉显示设备上，并且可以在转换期间被发送到其他工厂计算机程序以进行指导。 生成植物和各个部分和部分事件序列（包括相关植物条件和信息）的事件序列的永久时间序列记录，供后续审查和分析。
