Towards a unified approach to the design of knowledge based agile manufacturing systems: Part 1 - methodology
- Univ. of Salford (United Kingdom)
To date there are no general techniques available to design Knowledge Based Discrete Event Control Systems. In this paper, a new technique is proposed which solves the problem. The generality of the technique means that the method can be applied to any complex (multi-component) Discrete Event Control problem and can easily accommodate diagnostics and reconfiguration. The technique involves firstly, defining the complex Discrete Event Control system as a colored Petri net controller and then converting colored Petri net controller into a colored Token Passing Logic Controller via Token Passing Logic (TPL) technique and finally, representing the colored Token Passing Logic Controller as rules within a control knowledge base for use within a concurrent inference engine. The technique is described by considering the fundamental structures inherent in colored Petri net control design and shows how to convert these structures into a knowledge base suitable for Discrete Event Control. Moreover, a context sensitive concurrent inference engine is also proposed to ensure the correct processing of the control knowledge base. An illustrative example of how this methodology can be applied to a complex discrete event control problem is described in Part II.
