Many formal modelling notations for business processes have been proposed during the last decade. They can be broadly classified into high-level visual notations, with an intuiti...
: This paper presents a genetic algorithm based approach for algebraic optimization of behavioral system specifications. We introduce a chromosomal representation of data-flow gr...
Abstract. Formal methods emphasizes the need for a top-down approach when developing large reliable software systems. Refinements are map step by step abstract algebraic specificat...
This paper introduces process spaces, a unified theory of interacting systems. The trait, abstract executions, leads to a simple and general set formalism. For concurrent systems ...
We present a rigorous but transparent semantic de nition of VHDL'93 covering the complete signal behavior and time model including the various wait statements and signal assi...
