Document Summary
The purpose of maintenance and reliability is to maintain the capability of the system: good maintenance removes variability, variability processes and creates wastes. Maintenance: activities involved in keeping a systems equipment in working order: can be disruptive, inconvenient, wasteful and expensive when done poorly. Preventive maintenance: routine inspection and servicing to keep facilities in good repair. Breakdown maintenance: emergency or priority repairs on failed equipment. Maintenance costs: the traditional view attempted to balance preventive and breakdown maintenance costs, typically, this approach failed to consider the true total cost of breakdowns. Increasing repair capabilities: well-trained personnel, adequate resources, ability to establish repair plan and priorities, ability and authority to do material planning, ability to identify the cause of breakdowns, ability to design ways to extend mtbf. Autonomous maintenance: consistent with employee empowerment system performance is enhanced when operators take ownership in their equipment and help to prevent breakdowns. Employees accept responsibility for: observe, check, adjust, clean, notify.
