  The existing approaches for scientific workflows composition face the
problems of domain knowledge integration. By this paper we summarize the
results, which have been elaborated and implemented during the 2-year research
concerning to Virtual Simulation Objects (VSO) concept and technology
development. The contribution of this paper consists of formal models of the
VSO internal structures and user-assistance logic, which may be obtained as a
result of the reasoning over knowledge base. (This paper was rejected to appear
in "Recent Advances in Knowledge Based Technologies and Applications" by
Hindawi in 2014, but was stolen and published by Ke Han under the name "The
Study on Workflows Composition Based on Virtual Simulation Objects Technology")
