Specification of formal development demostrator

This task is divided into two activities: a) Specification of a formal development demonstrator prototype. The specification of the formal development demonstrator will be based on the use case developed in Shift2Rail-(X2RAIL-2): 5.4.1 Development of Systems with standardized interfaces and it will consist in the identification of the overall process to be followed for the formal analysis and establishing the criteria for suitability of supporting tools. In particular, the definition of the architecture of the formal development demonstrator will include the choice of appropriate formal methods and tools to be integrated taking into account the results produced by current projects in SHIFT2RAIL: ASTRail, X2RAIL-2. Moreover, in this activity we will identify the tools for the description in standard interfaces (e.g. SysML) of the railway subsystem. (D2.1). b) Formal development demonstrator prototype. A detailed description of the process and framework constituting the demonstrator prototype will be released in (D2.2i, first draft). This description will show, in particular, how all the identified components will be integrated and used. This first release of the prototype will be validated on a selected portion of the railway signalling subsystem defined in T2.2. The detailed description of the process and the framework constituting the demonstrator prototype will be finalised in (D2.2f, final release), taking into account the results of the experimentation of the prototype done in Task 2.3. CNR will lead the task providing the specification and the formal development of the demonstrator prototype. ARD will contribute in the activity, ensuring the link with ASTRail. SIRTI will ensure the necessary link with the outcome of X2RAIL-2 and will lead the collaboration with the complementary project X2RAIL-3 through at least one collaboration meeting.
