Prioritize maintenance for ten power assets

Act as a fictional electric utility asset manager, distinguish HI from RUL, and prioritize ten assets within a limited budget and daily crew capacity.

Before the maintenance planning meeting

A weekly maintenance meeting is about to begin at a fictional electric utility. Sensor readings, inspections, dissolved gas analysis, and failure histories arrive on different schedules for ten assets. The maintenance budget is KRW 500,000, and no more than three jobs can receive a crew on the same day. Today, you are the asset manager choosing the first job in the plan.

Which assets should receive the limited budget and crews first, and what evidence supports that order?

A fictional utility asset team compares the condition and remaining-life ranges of ten power assets to allocate three first-day maintenance crews

Decision criteria for this mission

  • Perspectives in play — Asset analysis separates current condition from uncertainty in remaining life, while maintenance planning turns that evidence into an executable order within budget and crew limits.
  • Decision constraints — The plan has a KRW 500,000 budget and at most three crew assignments per day. RUL is an estimate with a 90% interval, not a fixed date or a declaration of failure or safety.
  • Completion signals — Trace EQ-005 through HI 76.2767 (B), RUL 1.9813 years, and relationship context, then explain why EQ-008 at 0.3501 ranks first and EQ-005 at 0.3427 follows.

Workshop goals

  • Distinguish how sensors, inspections, and DGA describe current condition.
  • Read Health Index (HI) as a summary of several condition checks.
  • Interpret Remaining Useful Life (RUL) as an estimate with a range, not a fixed date.
  • Trace one asset from source evidence through relationship context and its planned work.
  • Explain the first maintenance choice, including constraints, uncertainty, and missing evidence.

Each chapter follows question → reason → action → observation → interpretation → next decision. Instead of memorizing algorithm names, follow EQ-005 from its source clues to its scheduled work and compare it with the asset that ultimately ranks first.

Learning journey

  1. Start with the maintenance meeting question15 minImport the HS asset-management scenario and separate the four evidence layers needed to prioritize maintenance.
  2. Summarize condition clues with HI15 minCombine EQ-005's sensor, inspection, DGA, and operating clues into a Health Index and read it separately from thermal anomalies.
  3. Read remaining life as a range15 minDistinguish a Weibull RUL point estimate from its 90% interval, operating-condition factor, and hazard rate.
  4. Trace EQ-005's asset context20 minConnect EQ-005 to its subsystems, sensors, inspection, and planned maintenance while interpreting missing relationships.
  5. Turn the evidence into a maintenance plan15 minCombine HI, RUL, hazard, and asset criticality, then schedule the first jobs within budget and crew constraints.
  6. Check the maintenance-priority evidence5 minBefore the final explanation, review HI and RUL, relationship gaps, the schedule rule, and field limits in four questions.
  7. Explain the maintenance priority with evidence5 minReturn to the planning question and explain the order of EQ-008 and EQ-005, its evidence, uncertainty, and remaining checks.
