    • It is the objective of the present invention to provide a method for operating a plurality of edge production resources by a manufacturing execution system that requires less investments into the centralized MES architecture and guarantees low latency in data transmissions and high throughput of manufactured products.
      This objective is achieved according to the present invention by a method for operating a plurality of edge production resources by a manufacturing execution system, said method, comprising the steps of:
      a) providing a number of interlocking edge apps and track and trace edge apps to the production resources at shopfloor level;
      b) providing a number of higher-level interlocking apps and higher-level track and trace apps also related to the edge production resources at an elevated supervision level wherein the edge apps provide only a subset of functionalities as compared to the central, higher-level apps at the elevated supervision level;
      c) creating a bill of process at the elevated supervision level thereby defining a number of products to be produced on at least one of the edge production resources;
      d) loading the data for the production of a subset of the number of products defined in the bill of process into the cache of the respective edge production resources;
      e) producing the subset of the number of products according to the defined bill of process by the respective edge production resources;
      f) exchanging data between the edge apps and the higher level apps during the production of the subset according to the functionalities defined in the edge apps and in the higher-level apps;
      g) after completion of the production of the subset of the number of products, deleting all data related to this subset of the products in the caches of the edge production resources, and
      h) processing the data related to this subset of the number of products in the higher-level apps according to the functionalities provided by these higher-level apps.
      Thus, the present method paths a way to distribute the track & trace and interlocking functionalities in a smart way over the MES architecture thereby benefitting from small and flexible edge structures and reliable and powerful higher level structures. In particular, the deletion of all data related to a product for that the production is finished, allows to "reset" the edge apps and refresh them functionality-wise and storage-wise for the production of the next bunch of products.
