Study Notes

Maintenance Planning & Scheduling

Maintenance planning ensures the right tools, materials, and instructions are available for efficient work execution.
A computerized maintenance management system (CMMS) is used to raise and track work requests, including problem details and locations.
Work requests are reviewed for clarity and prioritized based on severity and potential production impact.
Maintenance planners diagnose issues on-site to identify necessary materials and document everything in the work order.
Materials are ordered and confirmed for accuracy before jobs are marked ready for execution in the CMMS.
Schedulers create draft weekly schedules, grouping similar tasks to enhance crew efficiency.
Weekly schedule review meetings involve operations and maintenance teams to finalize work to be executed.
Agreed schedules are distributed to maintenance supervisors for assignment to crew members.
Workers keep records of time spent and provide technical feedback post-execution, aiding in performance analysis and process improvement.

Key Formulas in Maintenance Planning

MTBF (Mean Time Between Failures): Average time between equipment failures, assists in predicting potential failures.
MTTR (Mean Time To Repair): Average duration to repair equipment, helps estimate downtime after failures.
Availability: Percentage of time equipment is operational, calculated as Availability = MTBF / (MTBF + MTTR).
Utilization: Percentage of time equipment is actively used, calculated as Utilization = Actual Operating Hours / Scheduled Operating Hours.

Maintenance Management Systems

Preventive Maintenance Checklist: A tool for tracking and managing preventive maintenance tasks.
Opportunity Maintenance Identification: Identifies tasks that can be performed during operational downtimes.
Composite Maintenance Planning: Develops maintenance plans considering equipment condition and operational history.
Breakdown Response: Facilitates swift response to breakdowns, providing immediate access to pertinent resources.
Equipment History Tracking: Maintains records of maintenance and repair activities for each asset to identify trends.

Reliability and Maintainability

RAM Analysis: A methodology assessing asset performance covering Reliability, Availability, and Maintainability for a comprehensive health assessment.
Components of RAM Analysis:
- Reliability: Capability of an asset to perform required functions under specified conditions.
- Availability: Asset's operability as needed under varying conditions.
- Maintainability: Ease and speed with which an asset can be repaired post-failure.
