After Marsha’s keynote, we are bringing you today the second keynote talk we had the chance to enjoy at ECMFA’14: Darren Buttle talked about “Under the Hood: Model-Based Development in the Automotive Industry”.
As he says, “Today’s vehicles include an astonishing amount of software… The automotive industry was an early convert to model-based software development … By the late 1990’s, code generated from physical system models could be found in series production vehicles… In some vehicle domains, notably power train and chassis control, model-based development is the dominant software development paradigm. In this talk, we’ll talk about: – Where is model-based development used? – What speci c challenges are presented by the domain? – Which technologies have proven successful? and What are the current trends and tomorrow’s challenges?”
To know more about his view on MDE, you can read his extended abstract or (better), sit down and enjoy the slides he used in his talk (below), just read some of the key data points he mentioned and that I found specially interesting / surprising (comments and misinterpretations are mine):
“Only” 80 milion cars produced every year (I thought it was much more!)
20M of source lines of code (SLOC) in a car (up to 100M if you add the entertaining system. Compare this with the 650.000 you have in an airplane
Software bugs cost a lot (e.g. 1200$ per line of code due to recall of cars after an unintended accelartion problem)
A model-based approach (model + code-generation) is 30% faster and has 50% less errors than manual code written by a top programmer
16% of the SLOC in a car are generated from models
