The MIST project is developing a system architecture that incorporates an integrated production planning and control environment. The architecture is composed of an integrating infrastructure and a set of modules, one for each manufacturing function. Manufacturing functions which are specified include process planning, production planning (resource allocation and scheduling), other entry, and control. The MIST architecture identifies data which need to be either available to, or exchanged between manufacturing systems and specified information models for this data. These information models will be provided as input to appropriate standardization efforts.
This paper will describe the MSI project and provide a summary of the MSI architecture. It will explain the control and production planning paradigm used and describe provisions for error recovery. It enumerates the information models used by the modules and identifies the interfaces between them.
