ABSTRACT:
A computer based proactive process control technique used to predict the capability of a manufacturing process. A solid model of statistical process control is created by a computer program to simulate the Bell Curve of the data or the data with in +/−3 standard deviation. With product knowledge and process knowledge, it is possible to setup and control the manufacturing process to yield a desired level. The computer program operates within a communication media network. Suppliers and manufactures through their main servers are connected to floor computers, which are data input and output computers. All the servers are connected to the main server of a prime contractor. Manufacturing data from the supplier's field computers goes to their respective servers, and that data in turn goes to the main server of the prime contractor. From the prime contractor server, the data can be retrieved through computers that are data reviewing stations.
