Maintenance Scheduler

Overview

The Maintenance Scheduler skill provides comprehensive capabilities for planning and scheduling maintenance activities. It supports preventive maintenance scheduling, autonomous maintenance checklists, predictive maintenance integration, and TPM pillar support.

Capabilities

• Preventive maintenance scheduling
• Autonomous maintenance checklists
• Predictive maintenance integration
• Spare parts planning
• Work order management
• MTBF/MTTR tracking
• Maintenance backlog management
• TPM pillar support

Used By Processes

• LEAN-005: Standard Work Documentation
• CAP-002: Production Scheduling Optimization
• QMS-001: ISO 9001 Implementation

Tools and Libraries

• CMMS systems (Maximo, SAP PM, Fiix)
• IoT sensors
• Predictive analytics platforms
• Mobile maintenance apps

Maintenance Types

TPM Eight Pillars

Reliability Metrics

MTBF (Mean Time Between Failures)

MTBF = Total Operating Time / Number of Failures

Example: 1000 hours / 5 failures = 200 hours

MTTR (Mean Time To Repair)

MTTR = Total Repair Time / Number of Repairs

Example: 25 hours / 5 repairs = 5 hours

Availability

Availability = MTBF / (MTBF + MTTR)

Example: 200 / (200 + 5) = 97.6%
