A design pattern for model based software development for automatic machinery

The paper presents the results of the application of object-oriented modeling techniques to thecontrol software design of complex manufacturing systems, with particular focus on automaticmachineries for production and packaging of food stu, as milk, snacks, etc.In this application elds there are some peculiar problems to tackle in order to develop eectivesoftware control solutions, as for example the exception handling caused by product or packagingmaterial jam, the Human Machine Interface, the recipe production management etc.The goal of this paper is to introduce design patterns developed in the framework of UML appliedto the development of automatic machineries software, aiming to dene a set of predenedmodeling solutions to some class of recurrent design problems.
