Characterization of model based development of embedded control systems from a mechatronic perspective ; drivers , processes , technology and their maturity

Model Based Development (MBD) and many similar terms flourish in current literature and conferences, indicating the high industrial and academic interest in this topic as one key technique for promoting quality and cost-efficiency in the development of embedded systems. However, MBD is currently interpreted and approached in many different ways. Many companies are still hesitating towards the introduction of MBD, while others are applying MBD – however, mainly as a basis for partial subsystem development. In this paper a definition of MBD is provided. Based on this definition the drivers, opportunities and problems facing MBD are investigated. A framework is provided to understand and compare different MBD approaches. We discuss adoption of MBD in different fields of engineering and, relating to the Capability Maturity Model, present a model of MBD maturity and illustrate its application. The model allows explanation of potential problems perceived when introducing MBD and can thus hopefully be an aid when introducing MBD or when analyzing problems with an MBD approach. The target of the analysis is disciplines related to embedded control systems, and throughout the paper examples from automotive applications are given. Problems related to MBD are concluded to be the result of mismatches between the process maturity level, the drivers and the supporting technology.
