Resource OEE Configuration#

OEE stands for Overall Equipment Efficiency and it offers a simple algorithm to measure and evaluate equipment corrective action methods, ensuring permanent productivity improvements. The actual report is available in Critical Manufacturing MES (Resource OEE/), but requires several configuration steps.

Here are a few steps to configure Critical Manufacturing MES for optimal OEE calculation:

  • Calendar Days must be generated for the Calendars of the relevant Areas. For more information, see Generate Calendar Days.
  • Each Resource must have an associated State Model (by default SEMI E10 and SEMI E58 are provided). For more information, see State Models.
  • The ResourceIdealCycleTime smart table must be filled in with the appropriate values for your production environment. For each combination of Product per either Resource, Resource Type or Resource Model, define:
    • For each Product define Time Scale, Time per Unit and whether the Product is to be used as a reference.

Info

The reference Product is the standard Product whose Cycle Time is used to normalize the produced volume of different Products with different cycle times.

Below you can see an example of the calculations for a Resource processing four different Products in the same day:

TimeScale TimePerUnit Reference Ratio Physical Volume (24h) Normalized Volume (24h)
Product A Seconds 10 Yes 1.0 8640 8640
Product B Seconds 8 No 0.8 10800 8640
Product C Seconds 12 No 1.2 7200 8640
Product D Seconds 14 No 1.4 6171 8640

Table: Resource processing different Products in the same day

TimeScale TimePerUnit Reference Ratio Hours Physical Volume (24h) Normalized Volume (24h)
Product A Seconds 10 Yes 1.0 4 1440 1440
Product B Seconds 8 No 0.8 6 2700 2160
Product C Seconds 12 No 1.2 8 2400 2880
Product D Seconds 14 No 1.4 6 1543 2160
24 8063 8640

Note

The normalized volume represents the volume converted to the reference Product (Product A)
