Why is model-based systems engineering (MBSE) important for aircraft development ?
Siemens – The heart of the problem is that engineering organizations are not set up to tackle the integrated complexity of the current aircraft. In the past, aircraft were simply complicated systems.
Engineers used to develop an aircraft as “a system-of-systems” split into various isolated subsystems. Separate departments would individually design separate subsystems and very often distribute the work according to various Air Transport Association, or ATA, chapter numbers. For example, ATA 32 is Landing Gear and ATA 24 is electrical power.
So, still today in most cases, the complete aircraft development ecosystem, including suppliers and risk-sharing partners or RSPs, still communicates through documents.
How can communicating through documents successfully translate the integrated system functionality and complex dynamic interaction including control software that is the modern-day aircraft?
Well, this so-called “document-based-systems-engineering” is one of the key symptoms that cause these high-end, experienced and professional aerospace organizations to systematically suffer integration problems. more> http://tinyurl.com/qg7zmhw
