Analysing a Waste Event

In the Waste application, you can access the Key Performance Indicators (KPIs) and a summary of the generated waste. You can analyse the wastage that occurred for an event, and perform an analysis based on the various KPIs that are available.

Procedure

  1. Access the Waste page.
  2. Select the KPIs tab.
  3. In the VIEW BY box, select the time range for which you want to perform the analysis.

    The page displays the key performance indicators for the selected time range. The charts displayed on this page are generated by the OEE Dashboard app.

    The following KPIs are displayed:
    • OEE: Overall equipment effectiveness (OEE) is a measure of production health or status. By comparing OEE between machines or group of machines, you can identify lines or machines with production inefficiencies like waste, downtime, speed/performance loss, and production throughput that contribute to lower OEE.
    • Quality: You can review the quality rate to identify lines with high waste counts, which reduces quality and contributes to a lower OEE.

      For more information about OEE and Quality KPIs, refer OEE Dashboard.

    • Waste Statistics: Two key concepts are used to derive this analysis. They are:
      • Mean Amount Per Event (MAPE) which is the mean amount of waste that is generated for an event.
      • Mean Amount Between Event (MABE) which is the production amount calculated between two consecutive waste event.
    • Top Waste Cause: This chart displays waste events by the cause or reason associated with the generation of the waste. You can choose to view this chart by the quantity of waste generated (Quantity) or by the number of events (Count).
    • Waste by Product Code: This chart displays waste events generated by product. You can choose to view this chart by the quantity of waste generated (Quantity) or by the number of events (Count).

Example

Note:

These KPI metrics are based on the OEE Aggregation Store setting. If OEE Aggregation Store is set to False, the values are recalculated every time the chart is opened or refreshed. If it is set to True, the values are populated from the OEE Aggregation tables. For more information, refer to the OEE Aggregation Store topic.
