About the Production Summary Plot

The following table provides details about the categories (options in list) and subcategories (legend below the plot) that appear on the Production Summary plots. The calculations used in each subcategory are listed in the Calculation column.

Subcategory	Main Category	Question	Calculation	Example
Good Production	Production Event Code Impact Code OEE Code	What percentage of periods contains an Actual value that is greater than or equal to the Planned Production value?	Good Production = (Σ All Actual Values / Σ All MSC Values) x 100	The sum of all Actual values is 45,000. The sum of all MSC values is 65,000. Therefore: Good Production = (45,000 / 65,000) x 100 Good Production = .6923 x 100 Good Production = 69.23%
Unaccounted Loss	Production Event Code Impact Code OEE Code	What percentage of available time was the production unit not scheduled for production?	Unaccounted Loss = [(Σ All Short Range Values - Σ All Actual Values - Σ All Losses) / Σ All MSC Values] x 100	The sum of all MSC values is 80,000. The sum of all Short Range Plan values is 65,000. The sum of all Actual values is 45,000. The sum of all Loss values is 16,000. Therefore: Unaccounted Losses = [(65,000 - 45,000 - 16,000) / 80,000] x 100 Unaccounted Losses = (4000 / 80,000) x 100 Unaccounted Losses = .05 x 100 Unaccounted Losses = 5%

One day, the MSC value is 5,000, and the Short Range Plan value is 4,000. So, the No Planned Production Value is 1,000 (5,000 - 4,000). Another day, the MSC value is 5,000, and the Short Range Plan value is 3,000. So, the No Planned Production Value is 2,000 (5,000 - 3,000).
