Conversations are a useful means of structuring communicative interactions among agents. The value of a conversationbased approach is largely determined by the conversational model it uses. Finite State Machines, used heavily to date for this purpose, are not su cient for complex agent interactions requiring a notion of concurrency. We propose the use of Colored Petri Nets as a model underlying...

In this paper, we extend the supervisory control theory and a supervisor synthesis problem to a class of colored Petri nets. More speciically, we investigate the forbidden state control problem with full observation in which the discrete-event system is modeled as a colored Petri net with a symmetry speciication. This problem is decidable if the colored Petri net has nite color sets and bounded...

The de®nition and maintenance of work¯ow processes have become important tasks for enterprises as work¯ow management systems (WFMS) are systematically applied to critical business processes. In order to simplify the management and usage of work¯ow processes and to integrate with other applications, a good modeling method is essential. The WFCP-net (work¯ow-net based on colored Petri net) is an ...

E-contracting, i.e., establishing and enacting electronic contracts, has become important because of technological advances (e.g., the availability of web services) and more open markets. However, the establishment of an e-contract is complicated and error prone. There are multiple negotiation styles ranging from auctions to bilateral bargaining. This paper provides an approach for modeling mul...
