Abstract:
The purpose of this article is to make a holistic compilation of many different types of requirements for an automotive electronic communications / control network (though the framework is in itself more generally applicable), and organize them into an easily reusable framework. Requirements have to be correct, consistent and complete. The issue of correctness of the specification should be dealt with formal validation models. The issue of consistency can be handled through domain expert specification reviews. The completeness issue can be dealt with by comparison with a reference, and this paper proposes a metamodel to help with the completeness and strategic consistency issues in the requirement specification process. The requirements framework proposed in this paper aims to answer the question: “What is the requirements design space for an automotive electronic communications network?”, and help in the completeness of the requirements specification through a holistic, multi-perspe
ctive, Bird’s Eye View. The main perspectives that will be examined in this requirements design space exploration are four: a) The “Nature of the User” perspective, b) The “Nature of the Application” perspective: Distributed, Real time, Safety-Critical applications, and Resource Constraints requirements, c) The “Nature of the Process Development” perspective, in particular, the component based development (CBD) process of Electronic Subsystem Design within Automotive Companies: component architecting, component assembly and component provisioning, and d) The “Nature of the Industry” is given by the competitive environment: Suppliers, Substitute Products, Substitute Technologies, Competitors, Potential Industy Entrants, the Company and its Clients.
