Human operators in abnormal situations must plan adequate countermeasures against abnormal corrections in chemical plants. Operators in these situations switch some of controllers from automatic to manual and manipulate one variable while observing another during each countermeasure and/or change the set values for the throughput controller when some manipulated variables have become saturated. However, a flow rate controller may not work for a throughput controller in abnormal situations. Therefore, the efficiency of countermeasures needs to be checked by systems that support operators. Hamaguchi et al. proposed a method of configuring a multi-loop controller using CE-matrices for a system that planned countermeasures. We propose a method of checking the consistency with which inventory is controlled so that adequate countermeasures can be planned.
