Top down designing spacecraft in CAD applying knowledge-based parametric patterns

The article demonstrates that creating theoretically grounded data model and product development processes within a common information space of the enterprise using the top down design approach is the assignment to be performed if the researchers take into account a wide variety of the interrelated issues, such as: managing the changes and configuration, reusing data, realizing the advantages of knowledge-based patterns. The similar data models and processes are currently demanded, since their implementation significantly reduces the time and money expenditures and improves the product quality at its development stage. The authors present their methodology of top down designing spacecraft based on top level CAD using knowledge-based patterns of spacecraft structure elements.
