Abstract:
The Safety Model based Software Development Life-cycle, focused on high-level executable models of the automotive systems to be fielded, has a high maturity level. It allows compression of the development cycles through a wide range of exploration and analysis including high fidelity of simulation,automatic test case generation and even test session at low cost early in the development phase. Many Software Development Teams in the automotive industry are already using model-based development for their safety critical software. The current software development effort estimation through sophisticated models and methods (COCOMO COnstructive COst MOdel, COCCOMOII, functional point, etc.), obtained at the early stages of development life cycle, is often inaccurate because of the long duration between the initialing phase of the project and delivery phase. Also, not many details of the functions are available at that time. All these models require as inputs accurate estimates of specific attributes, such as line of code (LOC), number of complex interfaces, etc. that are difficult to predict during the initial stage of software development. Effective software project estimation is one of the most challenging and important activities in software development. Proper project planning and control is not possible without a sound and reliable estimate. The basis of our approach for estimation of the development cost of a new model based development project is to describe it in terms of complexity and then to use this description to find other similar model–based functions that have already been completed.
