Abstract

A process abnormal condition recovering operation supporting system includes an information storing apparatus and an operation supporting apparatus. The information storing apparatus includes a data storing section which stores various data including process data, a statistics calculating section which executes statistics calculation with using stored data, and a data searching section which searches across the stored data. The operation supporting apparatus has a displaying section which picks out data from the information storing apparatus via an information searching apparatus when the operation support apparatus receives an alarm generated in a process abnormal condition, to display information for execute a process recovering operation. The operation supporting apparatus collects a plurality of formatted information including related process data, related equipment, operation history, and maintenance information according to a type of the alarm with using the information searching apparatus in compliance with predetermined procedures, to display the collected information on the displaying section.

Claims
