description	Run a PM program against maintenance CPM and downtime so a deferred PM doesn't become a roadside failure. Reach for this when repair costs rise.

Skill: Run preventive maintenance to CPM

PM is cheaper than the breakdown.

Step 1 — Read maintenance CPM

Maintenance cost ÷ miles, by truck and age (§3 #5).

Step 2 — Measure unplanned downtime

Separate planned PM from unplanned failures.

Step 3 — Tighten the PM schedule

Set PM intervals that beat the failure curve.

Step 4 — Call replacement on lifecycle

Replace when rising maintenance CPM exceeds new-iron cost.

Output

A maintenance-CPM read, a downtime split, a PM schedule, and a lifecycle replacement call.
