Design patterns for model-based automation software design and implementation

The paper presents the application of object-oriented modeling techniques to control software development for complex manufacturing systems, with particular focus on case studies taken from the packaging industry and design patterns that can be abstracted from such case studies. The proposed methodology for control software modeling and implementation is based on a practical approach refined on the basis of on-the-field experience and interactions with control engineers involved in the development projects. The final objective of the paper is to review and analyze patterns for the solution of design and implementation issues that typically arise in the considered application domain.
