What is the Key Issue In Process Control?
What settings of our process will make the results “better”? Many manufacturing processes are well suited to Data Mining because they are controlled using sophisticated process control systems. Sensors keep track of and store process parameters such as pressures, flow rates temperatures, efficiencies and other variables that are needed to monitor the process. Thus huge amounts of data are collected and stored. Computers monitor the output from the sensors and order adjustments to keep the process within the proper levels. The question is – what are the proper levels? There are so many variables, each with a range of operational values that change with time and have complex non-linear interaction with the other variables that even experienced and expert human operators are often unaware of what the desirable levels of the parameters are at any given time. The consequence of an improperly controlled manufacturing process can be costly because of some or all of the following factors: lowe
