Lost Production Cost Analysis

Quantify the cost of lost production as a monetary value, grouped by underlying reason.

Busroot is capable of calculating the of value of the production output by multiplying the production quantity by the SKU's value.

Therefore Busroot is also capable of calculating the lost production cost either through downtime (aka availability loss) , missed production target (aka speed loss) or as bad production (aka quality loss).

The Lost Production Cost is shown as a total on the Interval Chart, and broken down into each component on the OEE Analysis page.

SKU Value

The SKU value is a configuration for each SKU in your Busroot account. The exact meaning of this number can be different for different types of manufactures. The critical aspect is that the value represents an accurate relative value between SKUs.

Idle Cost per Station Minute

As well as a SKU value, it is possible to set an idle cost for each station. This is used to calculate the lost production cost where a SKU value is not defined, therefore the cost is just based on the duration the station is idle. Such as scheduling losses, planned non-production losses and downtime losses where the SKU value is not set.

Downtime Loss Cost

The number of units lost due to downtime, across a given time frame, is the downtime duration divided by the SKU's target cycle time. Another way to think of this is the ideal production quantity minus the target production quantity.

This lost quantity is then multiplied by the SKU value. If the SKU value is not set, the downtime duration will be multiplied by the station idle cost as a fallback.

Speed Loss Cost

The number of units lost due to slow production is the target production quantity, minus good and bad production. This lost quantity is then multiplied by the SKU value.

Quality Loss Cost

This is simply the quantity of bad production multiplied by the SKU value.
