Towards Maude-Tla based Foundation for Complex Concurrent Systems Specification and Certification

This paper contributes towards a multi-paradigm approach for the specification validation verification and refinement of concurrent agile systems. It brings together two complementary rigorous and largely accepted frameworks: Meseguer´s true- concurrent Rewriting Logic (RL) with its MAUDE prototype and Lamport´s Temporal Logic of Actions (TLA) with its current prototype TLA⁺. At the specification / validation phase, we adopt a variant of MAUDE that we endow with strategy for controlling rules and state splitting / recombining for exhibiting full intra-concurrency. For the verification / refinement phase, we automatically derive TLA´s formulas from validated MAUDE specification, on which crucial properties are checked using TLA´s deductions and invariants. A production system is considered as proof-of-concept.
