Implementing Formal Evaluations of Design Decisions Similarity for Upgrading Machine Components Pre-Production

Automation level of design decisions support for machines components pre-production does not exactly meet today's requirements. Today pre-production in general is characterized by low level of formalization of relationships and connections, forming in it. Formal quantitative evaluations, allowing effective evaluation and implementation of portability (similarity) of design decisions are. poorly used. Research, aimed on revealing and using for pre-production efficiency the upgrading of relations and quantitative formal estimations of the structural and technological design decisions similarity, is quite actual. Presented work demonstrates scientific-methodical approach to determining and using for machines components pre-production of quantitative estimations of the structural and technological design decisions similarity on the basis of the components models decomposition to complexes of surfaces, united by forms forming technologies similarity. We have found stable relations between quantitative estimations of the structural and technological similarity of the compared components. Document includes proved applications for evaluating design decisions similarity when preparing production: directional forming groups of technologically similar components; evaluation of production system technological potential and of possibility of effective producing of specified nomenclature components in such system; designing technical (technological) complexes for producing machines components.
