OEE, MTBF and MTTR, downtime cost, optimal preventive interval, redundancy, spare parts, life-cycle cost and maintenance KPIs.
Calculate OEE and TEEP from the six big losses, see the time waterfall and what each OEE point is worth, and compare improving OEE, adding a shift or buying a machine.
Availability, performance, quality, lossesCalculate MTBF, MTTR, failure rate, inherent availability and the probability of running without failure, with a Weibull fit from times between failures and B10 life.
Failure rate, R(t), Weibull, B10Calculate the true cost of an unplanned downtime hour: lost margin, overtime, idle labor, energy, restart, scrap and penalties, and the payback of a preventive and predictive maintenance program.
Lost margin, restart, penalties, predictiveFind the preventive replacement interval that minimizes cost per hour from Weibull life, planned replacement cost and failure cost, and compare it with run-to-failure.
Age replacement, Weibull, cost per hourCompare 1-of-1, 1-of-2, 2-of-3 and other arrangements by availability and downtime hours, including common cause failure, and calculate the payback of a standby pump or compressor.
Standby, k-out-of-n, common cause, paybackCalculate how many spare parts to hold from Poisson demand during the lead time, weighing holding cost against the cost of downtime when the part is missing.
Poisson, service level, critical sparesCompare keeping and overhauling the current equipment with buying new by equivalent annual cost, find each option’s economic life and see the NPV, IRR and payback of replacement.
Life-cycle cost, economic lifeCalculate maintenance backlog in weeks, project it forward, size the crew needed to reach target and compare preventive share, emergency work, wrench time and cost as % of RAV.
