Abstract

A maintenance and management method of equipment for production operations, comprising: obtaining machinery component defect data by inspecting the equipment; performing countermeasures and inspections based on these data; obtaining defect frequency data and inspection standards data, classifying the defects of the equipment by importance; repeating an overall inspection based on the defect frequency data until the defect frequency data of all defect locations have lowered to a standard value or lower; then, producing operating standards data based on inspection standards data; and performing maintenance and management by individually feeding back the operating standards data to each operator, and a maintenance and management support system used for performing the method. The above maintenance and management method changes the forced deterioration of equipment to natural deterioration and standardizes the skill and knowledge level of each operator about the production machinery. Therefore, the service life of machinery components is extended and the time and cost necessary for maintenance and management can be reduced.

Claims

1. A maintenance and management method of equipment for production operations, comprising:

obtaining machinery component defect data by inspecting the equipment;

performing countermeasures and inspections based on these data;

obtaining defect frequency data and inspection standards data, classifying the defects of the equipment by importance;

repeating an overall inspection based on the defect frequency data until the defect frequency data of all defect locations have lowered to a standard value or lower;

then, producing operating standards data based on inspection standards data; and

performing maintenance and management by individually feeding back the operating standards data to each operator.

2. A maintenance and management support system of equipment for production operations, comprising:

means for storing in a storage device, using an input device, machinery component defect data that has been obtained by inspecting production machinery;

means for additionally storing in said storage device result data of countermeasures performed based on these machinery component defect data;

means for additionally storing in said storage device inspection standards data and defect frequency data obtained thereafter by inspection;

means for performing measures against locations with serious defects that have been obtained from the defect. frequency data, and repeatedly performing an overall inspection until the defect frequency parameters of all locations have been lowered to a standard value or lower; and

means for individually feeding back the stored inspection standards data to each operator by outputting them from the storage device via a processing device as operating standards data to an output device.
