Giving semantics to SA/RT by means of high-level timed Petri nets

摘要

In the IPTES project a dual language approach is proposed for overcoming both the problems derived from the use of a user-friendly, high-level, but not-formally-defined language and from a lower-level, formal, but difficult-to-use language. The approach uses a user-friendly, high-level language as user interface and a lower-level, formal language asmachine language. In this way the users can both access the IPTES environment through a nice interface and can profit from non-ambiguity-checks and proofs algorithms based on the formal kernel machine language. The correspondence between the two languages is built-in in the IPTES environment that provides a transparent mapping mechanism that relates the users specifications expressed by means of the high-level interface-language with the formal definitions expressed in the formal machine language.
