Operating state management system
First Claim
1. An operating state management system comprising database means and a computer for collecting and totalizing the operating states of production equipment and circumstances under which types of trouble occur in said production equipment, said computer including:
- correlating means for storing correlation data in said database means in a time series, the correlation data being obtained by linking the type of trouble that has occurred in the production equipment, the state of the production equipment, and time of day and date at which a change in the state occurred; and
totalizing means for totalizing states of the production equipment in a designated period of time on the basis of the correlation data.

Abstract
An operating state management system having database, to collect and totalize the operating states of production equipment and circumstances under which types of trouble occur in the production equipment, creates a record set Q of records in a designated range of times (ta, tb) on the basis of an operating status table in which the state of the production equipment and the time at which there is a change in the state are linked is stored in the data base in advance, and creates a trouble table on the basis of the record set Q (step S61-S73) and totalizes downtime of the production equipment by type of trouble on the basis of the trouble table (step S74).
