What is calculated how

After selecting a machine and a time range, OEE coach will calculate the financial result of that machine in that time range

Time

ItemSourceCalculation
DaysFilter: from-date Until-dateThe amount of days included in the filter: in days and daysx24 = hrs
[-]not scheduledcalculated hereDays – Shift time
Shift timeShiftdata (cycles)Sum of all shift-durations of shifts starting within the fitler
[U]nscheduledShiftdata (cycles)Sum of all [U]scheduled activities within the shifts within the filter
ScheduledShiftdata (cycles)Shift-time – [U]scheduled
(equals: sum of [P]+[W]+[F]+[L] activities within filter)
[L]ine restraintShiftdata (cycles)Sum of all [L] activities duration within the filter
[W]aitingShiftdata (cycles)Sum of all [W] activities duration within the filter
[F]ailureShiftdata (cycles)Sum of all [F] activities duration within the filter
[P]roductionShiftdata (cycles)Sum of all [P] activities duration within the filter

Cost of Time

FieldSourceCalculation
Avg/HrShiftdata – Teams Master: Each team in Teams-Master has an average hourly teammember rate. Different teams with different rates might have worked within the filter-periodSum of: all(shift labor time x teams hourly rate)
Weighted average of the involved teammember wages {needs clarification for multiple teams}
OpShiftdata (cycles)Amount of actual present operators per activity type.
For each type, sum of all (activity duration x Actual present operators) divided by total actual activity duration of that type
LaborShiftdata (cycles)Amount of actual labor minutes per activity type.
For each type, sum of all (activity duration x Actual present operators during that activity)
CostCalculated hereLabor time x Average Hourly wages

Overhead Costs

ItemSourceCalculation
Per Hourcalculated here from values in Machine Master24/7 costs in Machine Master divided by amount of hours in the year of the filter
Hrs within filter (right column)calculated hereHrs within filter x ‘Per Hour’

Conversion Costs

ItemSourceCalculation
24/7 costscalculated here from values in Machine Master(24/7 costs in Machine Master devided by amount of hours in the year of the filter) X Hrs in filter
Labor Costscalculated here Shift DataSum of all (Activity duration x actual operators x Team Wage)
Per [P]roduction Hr(Total 24/7 cost + Laborcost) devided by total [P]roduction hrs in filter
Per produced item(Total 24/7 cosy + Laborcost) devided by ALL produced items (G/S/SS/R)
Per [G]ood Item(Total 24/7 cost + Laborcost) devided by [G] products, produced within the filter

Produced Output: Each category has its own calculation

Good product

ItemSourceCalculation
# [G]oodShift dataTotal amount of all produced [G]ood items
Valuecalculated here from shiftdata en value described in MAPSum of all (produced [G]ood products x value in MAP)
material costcalculated here from shiftdata en value described in MAPSum of all (produced [G]ood products x material cost in MAP)
Conversioncalculated here from shiftdata en value described in MAPSum of all (produced [G]ood products x conversion cost/ produced item)
Handlingcalculated here from shiftdata en value described in MAPSum of all (produced [G]ood products x Handling cost in MAP)

In the same way the reject categories are calculated and displayed:

Scrap product

Rework product

SubSpec product

Output summary: result for all Output

ItemSourceCalculation
# Items ProducedShift dataTotal amount of all produced [G][S][R][SS] items
Valuecalculated here from shiftdata en value described in MAPSum of all (produced [G][G][S][R][SS] products x value in MAP)
Total costcalculated here Sum of all (material+conversion+handling) of all produced [G][S][R][SS] products
Total resultcalculated here Total Value – Total Cost
# [G]ood productscalculated aboveSum of all produced [G]ood products
Cost per [G]calculated hereTotal cost / #[G]ood Products
Result per [G]calculated hereTotal result / #[G]ood Products
