Round 13

Preventive Maintenance Scheduling Approach

A mid-sized fictional manufacturing plant runs three production lines that together account for nearly all output. Unplanned downtime is costly, but maintenance work itself also pulls machines offline and consumes technician hours that are in limited supply. The operations team must choose a single plant-wide approach for scheduling preventive maintenance on production equipment for the coming year. The goal is to minimize total downtime and cost while keeping the maintenance staff workload sustainable and avoiding surprises for production planners. Constraints include a fixed maintenance headcount, a fixed budget for spare parts and contractor support, and a requirement that any chosen approach be explainable to line supervisors who schedule shifts around maintenance windows. Tradeoffs include upfront investment in monitoring tools versus reliance on existing routines, predictability of downtime versus responsiveness to actual equipment condition, and the risk of either doing unnecessary maintenance or missing early signs of failure.

2.00 of 3 PPV winner
A Shift to usage-based triggers, where maintenance is scheduled after a machine accumulates a set number of operating hours or production cycles, aligning service with actual wear.
0.00 of 3
B Invest in condition-based monitoring sensors and schedule maintenance only when measured indicators (vibration, temperature, etc.) cross defined thresholds, accepting upfront cost and complexity for more precise timing.
0.00 of 3
C Outsource scheduling decisions entirely to a third-party maintenance provider using their own predictive models, trading internal control and cost for reduced staffing burden and specialized expertise.
0.00 of 3
D Keep a fixed calendar-based schedule where each machine gets maintenance at set intervals regardless of usage or condition, prioritizing predictability for shift planning.
0.00 of 3
E Move to a run-to-failure approach for non-critical equipment paired with strict calendar maintenance only for the few machines whose failure would halt the entire plant, minimizing maintenance labor spent on low-impact assets.
