Achievements and examples

・To improve the safe operating ratio of production equipment and breakdown maintenance
For some customers manufacturing particular products on a production line or assembly process, their main activity is breakdown maintenance due to frequent failures.
The purpose of maintenance is to raise the safe operating ratio by reducing prolonged lock-down caused by failures. When it is possible to understand correctly the circumstances of failures and shorten the recovery time based on past data, it enables a shift from breakdown maintenance to preventive maintenance. eServ improves maintenance operations and raises the safe operating ratio.

・Avoiding excessive preventive maintenance
For some customers manufacturing particular products in a continuous process, their main activity is preventive maintenance at a constant cycle.
This maintenance style leads to too much maintenance, because maintenance and inspections are conducted regardless of the amount of product manufacture or operating hours.
The cycles and procedures for proper preventive maintenance can be developed by understanding correctly the circumstances of failures and the conditions of production facilities and utility equipment. eServ supports proper preventive maintenance.

Ideally, the maintenance and manufacturing divisions should work together and share information, but this rarely happens in practice. eServ’s information-exchange function greatly promotes such communication.
