Abstract
The article develops a method for optimizing the cost and quality of innovative solutions at design stages of a life cycle of engineering high-tech items. The method allows evaluating and comparing a whole set of permissible options of innovative solutions on the basis of all partial and generalized criteria at the stage of production design engineering.The method is based upon a bipartite graph model of component interconnections in engineering high-tech items and the criteria of optimal option selection. To evaluate the options of innovative solutions, the authors form a set of partial criteria united in the categories: production criteria; investment criteria; criteria of evaluating the quality of manufactured products while using a high-tech item; economic criteria; financial criteria; criteria of evaluation on risk types; social criteria; environmental criteria; budget criteria; integral criteria evaluating the quality of an engineering high-tech item on the basis of all indices. To evaluate the cost and quality of innovative solutions, the authors form integrated efficiency functions presented as additive convolutions of partial criteria.The developed method is automated with the use of software tools MS Excel, MS Access, C#. The method industrial approbation demonstrates its operation efficiency and universal nature for solving various problems of the comparative evaluation of innovative solutions at the design stages of a life cycle of engineering high-tech items.
