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.

The article considers models and software tools for assessing the efficiency of industrial company production activity in connection with digital technology and manufacturing use. The method allows assessing and comparing a whole set of permitted alternative options of innovative solutions on the introduction of digital technology and manufacturing at the stages of product life cycle and production development. The method is based on a set of mathematical models used to form the tools for equipping manufacturing processes with digital technology and manufacturing components; forming a total of partial criteria to assess the efficiency of the company production activity as a result of digital technology and manufacturing introduction; searching for an optimal problem solution. In terms of the structure, the process of manufacturing re-equipment with digital technology and manufacturing use is presented in the form of the algorithm for the assessment of digital technology and manufacturing introduction efficiency within the already existing or being developed corporate information system consisting of nine stages. The automation of the developed method is conducted with software tools MS Excel, MS Access, MS Project, C#. The method industrial approbation demonstrates its operation efficiency for solving various problems of the comparative assessment of innovative solutions at the design stages of a life cycle of items and manufacturings.

The technique of automated control over the composition and structure of metalworking equipment is examined based on a set of criteria. Multitude of alternative structures and technical and economic solutions to the problem of overhaul or local re-equipment of production is formed on the basis of the developed multi-layer graph model. The generated mathematical model is defined on the set of Boolean variables and implemented using linear programming methods. The choice of an effective composition and structure of technical means for equipping technological operations is based on the results of an analysis of evaluation criteria that determine technical, economic, production and financial indicators of an industrial enterprise, as well as partial indicators of quality and competitiveness of production facilities.

In modern conditions, the system of interaction between the university and representatives of the real sector of the economy is one of the key factors of competitiveness. In this regard, the development of a model of interaction “university - industrial enterprise” is especially relevant. The purpose of the study is to confirm the hypothesis that the graduate is the main source of partnerships for universities. The objectives of the study are: analysis of the current partnerships between the university and the graduate of the largest technical universities of the Russian Federation; determination of the levels of interaction between the university and representatives of the real sector of the economy (industrial enterprises); development of a “motivation ladder” for the graduate on the way to his transformation from an applicant who considers the university from the point of view of an assistant at the start of professional activity to a strategic partner - an industrial enterprise that considers the university as a source of research competencies; the development of an original model of interaction “university - industrial enterprise” based on the principles of crowdfunding and managing the grad[1]uate development cycle as a partner from the applicant to the employer . The authors developed a “motivational triad”, reflecting the predictive utility of cooperation in the long term. To confirm the practical significance of the conducted study, digital communication outlines were designed that describe key business processes and the achieved result at each level of interaction between the university and industrial enterprises, which can be integrated into the digital infrastructure of universities. The research described in this article was carried out using the methods of observation, collection, analysis and systematization of information.
