[RESOLVED] calculate running efficiency of process throughput

[wolf99]

my prog has a function that every adjustable set period (with magnitude of mins) it calculates efficiency of the process based on throughput since the process started.

I have currently:

currentProductThrough / TargetForHour

I want to refine this so that efficiency will be correct as with the above 100% would (even in ideal situ) only be reached when the hour is up.

therefore I thought something like:

currentProductThrough / (TargetForHour/60)

if this is correct, to allow for the adjustable testing period then would need to be something like:

if the period equals (1min * period Coefficiant),

currentProductThrough / (TargetForHour/(60*periodCoefficiant)

if anyone understands what I'm on about, please let me know if Im on the right track or not

ah, I grasped what had been confusing me, the throughput figure I was using was not a total for just the current time period but a running total of the whole lot

to get the efficicency of the most recent period it needs to be something like this:

productThroughSinceLastCalculation / (TargetForHour/(60*periodCoefficiant)

meaning a true running calc would be:

productThrough / ((TargetForHour/(60)) * minutesProcessRunning)

(I Think )
