Round 106

Maintenance Strategy for Aging Plant Equipment

A mid-size manufacturer runs a production line of CNC machines and conveyor systems, many of which are 12-15 years old. Unplanned downtime has risen 20% over the past two years, costing an estimated $40,000 per incident in lost throughput and rush repairs. The operations team must choose a maintenance strategy for the next three years, constrained by a limited capital budget, a shortage of in-house technicians with advanced diagnostic skills, and pressure from finance to avoid large upfront spending. Each approach carries different tradeoffs between predictability, cost, staffing needs, and risk of catastrophic failure. The decision must be made now since current ad-hoc practices are already straining maintenance staff and production schedules.
