Model Checking based verification techniques represent an important issue in the field of concurrent systems quality assurance. The lack of formal semantics in the existing formalisms describing multi-agents models combined with multi-agents systems complexity are sources of several problems during their development process. The Maude language, based on rewriting logic, offers a rich notation supporting formal specification and implementation of concurrent systems. In addition to its modeling capacity, the Maude environment integrates a Model Checker based on Linear Temporal Logic (LTL) for distributed systems verification. In this paper, we present a formal and generic framework (DIMA-Maude) supporting formal description and verification of DIMA multi-agents models.

Agents Interaction Protocols (AIPs) play a crucial role in multi-agents systems development. They allow specifying sequences of messages between agents. Major proposed protocols suffer from many weaknesses. We present, in this paper, a formal approach supporting the verification of agents' interaction protocols described by using AUML formalism. The considered AUML diagrams are formally translated into Maude specifications. Based on rewriting logic, the formal and object-oriented language Maude offers an interesting way for concurrent systems formal specification and programming. The Maude environment integrates a model-checker based on Linear Temporal Logic (LTL) supporting formal verification of distributed systems. The proposed approach essentially allows: (1) translating the description of agents' interactions, specified using AUML formalism, in a Maude specification and, (2) applying the model-checking techniques supported by Maude to verify some properties of the described system. A case study is presented to illustrate our approach.
