Abstract
A solution is disclosed for an overall equipment effectiveness (OEE) analysis for a manufacturing execution system (MES) allowing a comparative analysis that makes it possible to build links and relations among the values found in a report with raw data acquired from the field. The solution is a web application running on a web server and on OEE databrowsers running on clients. In order to come to a comparative analysis an OEE-server is provided with the functionality to acquire data from the MES of the production plant, to perform scheduling for reports, and to perform run time query executions. Additionally the web server gets data from a data mining support database.
Claims14
A method for an overall equipment effectiveness analysis (OEE analysis) for a manufacturing execution system and the method running on a distributed architecture, the method comprises the steps of:
- providing a web server running a data mining service and a web application;
- providing browsers running on clients, the clients being connected with the web server;
- providing an OEE server connected with the web server, the OEE server performing the following service steps of:
- acquiring data from a field;
- scheduling of calculations for reports to be displayed on at least one of the browsers;
- executing runtime queries entered in at least one of the browsers;
- and
- providing a database server hosting an overall equipment effectiveness (OEE) database and a data mining support database, the data mining support database containing data for the OEE analysis and the data mining support database is used only by the browsers running on a client.
A distributed architecture for performing a method for an overall equipment effectiveness analysis (OEE analysis) for a manufacturing execution system, the distributed architecture comprising:
- a web server running a data mining service and a web application;
- clients having browsers, said clients connected with said web server;
- an OEE server connected with said web server, said OEE server programmed to perform the following services of:
- acquire data from a field;
- schedule calculations for reports to be displayed on at least one of said browsers;
- execute runtime queries entered in at least one of said browsers;
- and
- a database server hosting an overall equipment effectiveness (OEE) database and a data mining support database, wherein said data mining support database containing data for the OEE analysis and said data mining support database is used only by said browsers running on one of said clients.
