# 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](../../business-intelligence/analytics-views/performance/resource_oee.md)/), 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](../calendar/generate_calendar_days.md).
- Each **Resource** must have an associated **State Model** (by default SEMI E10 and SEMI E58 are provided). For more information, see [State Models](../../administration/state_models.md).
- The [ResourceIdealCycleTime](../../administration/tables/smart-tables/resourceidealcycletime.md) 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                    |

| Product B | Seconds   | 8           | No        | 0.8   | 6      | 2700                  | 2160                    |
| Product C | Seconds   | 12          | No        | 1.2   | 8      | 2400                  | 2880                    |

|           |           |             |           |       | **24** | **8063**              | **8640**                |
