<p>This paper presents the Epsilon language and defines its formal syntax and semantics. Epsilon is a language for the description of systems, which contain concurrent components, some of these being edp-equipment or by other means representing highly structured information handling. The actions consist of continuous changes described by equations, of communication between the components and of normal algorithmic actions.</p><p>Epsilon may be used for the description of computer systems together with their environments, e.g. production equipment and human operators. Parts of such a description may serve as the system specification from which computer programs are developed. Epsilon is not itself an implementable language.</p><p>This paper defines the semantics of Epsilon by means of a model based on high-level Petri nets, i.e. a model founded on the notion of concurrency. The model also uses denotational semantics and equation systems.</p>
