Financial OEE and TEEP, downtime cost, optimal preventive interval, backlog and crew sizing, spare parts stock and repair or replace decisions.
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 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 hourCalculate 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.
Backlog weeks, technicians, wrench time, RAVCalculate 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 lifeWork out what to charge per hour for field service, repair, calibration, machining or installation work: loaded technician cost, tools, vehicle, overhead, billable utilization, sales tax, selling expenses and margin, with a mileage rate, minimum call-out and a sample quote.
Hourly, mileage, quoteA waterfall chart explains, in one picture, how a starting value becomes a final value step by step. Use it to show where a machine’s hours are lost, how price turns into profit or why this year’s result changed. Enter the starting value, the increases and decreases and, if you like, subtotals, and the page draws the waterfall with colors for increase, decrease and total, connectors between bars and the value and % on each one. Ready-made templates for OEE losses (from calendar time to productive time, with OEE at the end) and for selling price to profit.
OEE losses, price → profitA Pareto chart sorts problems from largest to smallest and shows which few causes account for most of the defects, stoppages or costs, so you know where to start. Paste the categories with their counts (or the list of occurrences) and the page draws the Pareto chart with the cumulative curve and cut-off line, points out the vital few, groups “Other”, compares frequency vs cost, Pareto by stratum and before vs after, and exports PNG, one-page PDF and xlsx.
Vital few, 80/20, cost, strataImportant notice: Indus Metrics tools produce estimates and pre-sizing results from the data you enter and from published engineering methods.
