PURPOSE:To output an operation guide corresponding to a state of a plant, by calculating the index of a deviation from an objective with major process variables of the plant and outputting the operation guide through the selection of sub-systems. CONSTITUTION:A process variable deviation index calculating section 4 fetches major process variables and their changing rate of a main system 2 to obtain the deviation index of the process variable to an objective and gives the index to a sub-system start request selecting section 11. The selecting section 11 selects the process variables in which this deviation index is a preset reference value or more, and calculates an operation request index of each sub-system 3. A start request is outputted to a system 4 with an operation stop discrimination section 5 and a failure presence/absence detecting section 6 out of the systems 4 selected by the sections 5 and 6, in which the operation request index is a prescribed valur or more. An operation guide calculating section 12 outputs a start instruction or a stop instruction, or an instruction mitigating a process variable not satisfying limit conditions to the system 4 requested for the start. This instruction signal is displayed on a guide display section 13. |
