This project demonstrates an understanding of how a manufacturing organization can use the methodology of open systems integration to upgrade the design of the network architecture for their manufacturing information system. In upgrading the design of their manufacturing information system's network architecture, a limited application of the system engineering process is used to produce an initial conceptual design. As technology grows, many manufacturing organizations are taking the necessary steps to upgrade their operations to remain competitive in these changing times. This project explores this problem which many manufacturing organizations are experiencing as technology continues to leap frog past its current limitations. Many of the manufacturing organizations which have been in operation for years are having difficulties competing with many of the new manufacturing organizations with their current technologies. / Master of Science
