Concurrent systems are composed of a set of subsystems (processes, threads etc.) that must communicate between themselves to meet the system requirements. Modelling and programming languages provide different communication modes to handle synchronous and/or asynchronous communication between subsystems. The paper provides a survey of communication modes introduced to the Alvis modelling language and...
Priority management is crucial to the development of correct real-time systems. Applications of formal methods in the development process require to choose a suitable formalism that is capable of dealing with different priority management algorithms. The paper deals with priority management in the Alvis modelling language. One of the advantages of Alvis is its Haskell middle-stage representation that...
The applicability of formal methods to support for software development is discussed in the paper. Software for realtime systems (esp. Safety Critical Systems) is of special interest. Petri nets, Alvis language and temporal logic are examined in which way they may support the development process. Selected approaches for using methods and related examples are discussed to answer the question stated...
