Abstract: The authors considers the highest control level organization of a flexible manufacturing cell. The indeterminancy problem in Petri nets is discussed as well as a method for overcoming it by two control levels. The net is decomposed into individual robot nets and machines. A simple language for defining robot activation conditions is developed and used for defining knowledge base contents. A method for linking it with other control modules is given. Also, the solution performance is analysed.
Keywords: flexible manufacturing cell; control level; robot activation language; robot net, (individual).
