A NOVEL REQUIREMENTS METAMODEL FOR AUTOMOTIVE ELECTRONIC NETWORK DESIGN

Automotive electronic subsystems are resource constrained, heterogeneous, distributed, real-time systems, and may implement safety-critical, X-by-wire applications, requiring fault-tolerance. Specifying requirements for an automotive application is a decision making problem, where perfect rationality does not exist, and thus need to help, within our limited rationality, the decision making process. The purpose of this article is to make a step in that direction, by proposing a novel meta-model that offers four main analysis perspectives (User, Application, Development Process and Competitive Industry Analysis) to explore the automotive requirements space in a level of detail that permits attention management, problem decomposition and decentralized decisions.
