The QES (Quality Execution System)

The key features of a Quality Execution System (QES) are to track quality including decision support per individual piece produced, exchange sequence related information with the MES and ERP systems and feed process related information back into the set-up for the next piece. From all these activities, decision support is obviously the most important and critical activity, given the amount of investments into advanced monitoring and gauging over the recent years.

To implement sophisticated quality decisions, a number of steps need to be taken:

  • data from various data bases as well as much raw data as possible must be processed
  • data needs to be synchronized. A lot of data is time stamped (in various resolution from milli seconds to minutes as needed to guide the process. Decisions on products are not time based but per square meter and to decide, all data needs to be adjusted to match positions.
  • Decisions are first (a) individual per type of data und then (b) combining several quality characteristics. This is essential because a piece of metal may still be good on temperature and reasonable on surface but in conjunction, it's a block.

So, the core of a QES is definitively the data management. As a basis for a long, investment protecting roadmap, QuinLogic has created a Metal Object Model (MOM) as a foundation and backbone for all QES related applications.
