Method for interpretation of technical process e.g. product manufacturing process, in process control application, involves determining correlation value, and using correlation value for determining threshold value for detection points

摘要

#CMT# #/CMT# The method involves determining a correlation value by correlating information in detection points of a technical process with process information based on historical data. The correlation value is used for determining a threshold value for the detection points. The correlation value is determined as the threshold value for the detection point if a preset condition is fulfilled. An upper threshold value is determined by an upper correlation value, and a lower threshold value is determined by a lower correlation value. #CMT# : #/CMT# The information are time information, retention time information, processing time information, manufacturing time information and provisioning time information. Independent claims are also included for the following: (1) a method for performing a technical process (2) a device for interpretation of a technical process. #CMT#USE : #/CMT# Method for interpretation of a technical process e.g. manufacturing process, supply chain process and/or provision process of a product (all claimed) in an industrial application such as process control application, manufacturing application and storage application. #CMT#ADVANTAGE : #/CMT# The correlation value is used for determination of the threshold value for the detection points, thus ensuring an early detection of critical events e.g. premature completion of product, of the technical process flow in an efficient, flexible and reliable manner, reducing or eliminating effective false alarms during the technical process, ensuring larger user acceptance of the technical process based on high transparency, and providing dynamic aspects of the technical process. The technical process is automatically interpreted and implemented by using software and/or hardware. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a flowchart illustrating steps of a method for determination and/or interpretation of a technical system and/or process.
