> tbus ("Technische Berechnung und Simulation", see our logo) is our field of activity since about 50 years. In different industries, from aerospace to automotive, we have worked in the development of Computer-Aided Science-Based Models (CASBMs), which in context with appropriate experiments and tests solved very different problems in product design, from performance and maneuverability, over aerodynamics and structural integrity, down to human strain and comfort. We could do our work, because of the tremendous development of underlying sciences, and of increasingly cheap computer power over the last decades.

> But the more we pushed successfully any kind of CASB-Modeling and -Testing, the more it became clear to us, what tremendous waste of know-how and resources we supported: From the simulation and test results most often only a few values (of often many thousands) are used, and often the complete results are thrown away, if they do not meet the expectations of the problem owners. This objectively is a gigantic waste of know how!

> Enforced is this know-how dumping additionally by the restricted human capabilities to understand and handle any know how spreading in more than 2-5 dimensions. So, the overdeveloped computer-aided simulation and test capabilities overstress extremely the rather restricted human capabilities, to collect, integrate, understand, and refine such complex know-how contexts, especially in interdisciplinary problem environments: CASBM and Testing deliver tons of know-how, because of being supported by highly developed science and powerful computers, whereas human beings are heavily overwhelmed by this results, because of the restricted max 2-5 dimensional problem understanding capabilities.

> To overcome this missmatch between "science" and "experience", we developed and refined our CAEBM technology. Over the last about 20 years we worked on many CAEBM projects in very different application areas and for very different application patterns. This way, we "learned by example" about the different work steps to perform and about the (potential) problems to overcome. So, at this time, we can support nearly any kind of CAEBM project, based on our broad "example-based" experiences:

> Since Adam and Eve, examples are the most common and general structure to represent any kind of know-how from any source: So anything existing and any ongoing process can be understood as (a sequence of) examples. The same goes for results from CASBM and testing of course, see the left head in our logo.

Additionally, also results from Rule-Based Models (RBMs), like those in Expert Systems or Fuzzy Logik Systems (both rather outdated over the last decades), or just rules taken from any source (see our 3rd head), can be represented by examples, and last not least the same goes for know-how directly collected from arbitrary domain experts.

> So, our CAEBM technology, as it can reliably construct valid models from examples (see the symbolic neural network in the 2nd head), can collect, refine, integrate, and re-use know-how from any source. And that is, what CAEBM can do: Based on experience = examples, it makes "understandable" and re-usable for human beings (see our 4th head) even complex high-dimensional know-how contexts from any discipline and source, overcoming the max 2-5 dimension restriction, normally associated with human brains. And additionally, sophisticated Computer Aid is used to enhance the example-based know how handling capabilities in CAEBM, like it is used in CASBM for science-based know-how representation. As a consequence, the use of experience (in the shape of examples) is supported for humans with the same power and in the same quality, like it is done for analysis (by science).

Have fun with CAEBM,

 and be successful with your 

Know-how Engineering projects based on CAEBM,

 no matter how complex, high-dimensional, inter-disciplinary, scientifically un-explored etc the underlying problem may be!
