Question

Wrong effectiveness when produced quantity is zero

Hello, 

 

I have the following KPICacheValue:


"actualProductionTime_APT": 0.015583333333333333,
"goodQuantity_GQ_firstValue": 98,
"plannedBusyTime_PBT": 0.015883333333333333,
"plannedRunTimePerItem_PRI": 4.513,
"producedQuantity_PQ_firstValue": 98,
"goodQuantity_GQ": 98,
"producedQuantity_PQ": 98

And I get the following efficiency: 289

Why do I get this result? We are using ThingWorx 9.0.4-b539 with the MFG apps 9.0.0-01

 

(( Δ producedQuantity * plannedRunTimePerItem_PRI) / actualProductionTime_APT) *100

(98-98)*4.5/0.015583 -> should be 0

Hello,

 

Is it possible that the issue is caused because of a data mapping issue?  If that is not the cause, are there any related error messages returned in the ThingWorx log files?

 

Warm Regards,

 

John

Hello,

 

no there is nothing to see in the logs and the mapping is corrrect. This behavior only happens at the begining of the shift when the produce quantity is zero
