Module 4 - Maintenance Management
Machinery Maintenance

Finance Management
Minimum cost.
Continuous maintenance.
Total availability.
Keeping service to the users at a reasonably high level.
Keeping inventory investment reasonably low.
Cost-effective purchasing.
Stock is secure.
Stock identity, quantity and location are known.
Items are available and accesible when required.
Section Control plan - Control plan review and update criteria and linked to the PFMEA updates.
Section Verification after shutdown - The necessary actions after the shutdown period should be anticipated in the PFMEA, control plans, and maintenance instructions, as appropiate.
Total productive maintenance
- Strengthens the requirements for equipment maintenance and overall practive management of the Total Productive Maintenance (TPM).

TPM is a system for maintaining and improving the integrity of production and quality systems through machines, equipment, processes, and employees that add value to the manufacturing process. TPM should be fully integrated within the manufacturing processes and any necessary support processes.
Control of work.
Training and motivation.
Tactical decision to stay on schedule.
Administrative of personnel functions.
Job plan estimates for nonemergency work.
Work schedules by priority.
Ensure even low priority jobs are accomplished.
Maintains records, indexes, charts.
Reports on performance versus goals.
Improve the availability.
Identify and correct chronic and costly equipment problems.
Design and monitor an effective and economically justified maintenance program.
Maintain and analyze equipment data and history records.
Define training needes.
Do training programs.
Log activities.
Support management.
Keep logs.
Do reports.
"Economic" quantities save money.
Risk must be re-evaluated to reduce inventory
Consignment stock must cost more.
Software will solve the problem.
Putting items into inventory saves money.
Purchase orders are placed promptly and goods received effectively.

Human Error Management
Human error is inevitable
Recognition failures.

Memory failures.

Skill-based slips.

Rule-based Mistakes.

Knowledge-based errors.

Violations – deliberate acts which violate procedures.
¡Avoid Unnecessary Preventive Maintenance!
Key Principles
Human error is both universal and inevitable.
Errors are not intrinsically bad.
You cannot change the human condition, but you can change the conditions in which humans work.
The best people can make the worst mistakes.
People cannot easily avoid those actions they did not intend to commit.
Errors are consequences, rather than causes.
Many errors fall into recurrent patterns.
Safety-significant errors can occur at all levels in the system.
Error Management is all about managing the manageable.
Maintenance Quality Management is about making good people excellent.
There is no one best way.
Effective Maintenance Quality Management aims at Continuous Reform rather than Local Fixes.
Measures I
Person Measures
Provide training in error-provoking factors.
Implement measures to reduce the number of deliberate violations.
Encourage mental rehearsal of tasks before they are performed.
Control Distractions.
Avoid Place-Losing Errors.
Team Measures
Provide teamwork training.
Workplace and Task Measures
Ensure that personnel only perform tasks when they are properly trained, skilled and qualified.
Fatigue Management.
Assign tasks appropriately.
Ensure that equipment, and tasks, are properly designed.
Enforce good housekeeping standards.
Ensure Spare Parts and Tools are managed well.
Write, and Use, Effective Maintenance Work Instructions.
Measures II
Organizational Measures
Put in place effective processes for analyzing, and learning from, past failures.
Put in place proactive processes for assessing the risk of future maintenance errors.

Section Control of reworked product - the risk analysis and customer approval requirements are interrelated; FMEAs should identify and address risks related to each possible rework of the characteristics stated in the control plan.
Section Identification of statistical tools - the use of statictical tools from DFMEA, PFMEA, and the APQP process.
