This automated systems was developed for and implemented by a manufacturer of frozen meals. It was designed to provide multiple purpose controls for legal, costing and product integrity requirements over and above the traditional classic net weight control.
The system can be operated on a real-time, on line basis by the line operator, who performs routine weight checks and is able to adjust or interrupt the process accordingly. The system is designed for two-sided operating limits for each component separately, provides for continuous monitoring of the capability of each delivery system and accumulates data automatically for recording and reporting purposes.
The operator has the full responsibility for either resampling or adjusting the process, for staying above the legal minimum weight and for maintaining the relative proportions of each component to provide formula fidelity. Cost data for purposes of control and budgeting are also integrated into the software package.
The total system allows for the Quality function to be totally controlled by the line operator, including the decision to stop the line. The Quality Control personnel activities are limited to performing an audit function on the system - not the product.
The presentation will be made as a case study covering theoretical principles of statistical process control as well as specific applications in the development of the system. Discussion will include a general description of hardware and software packages.
