Optimization Modeling of Innovation Project Portfolio Resource Efficiency for Engineering Enterprises

The issue of industrial sector efficiency improvement is very relevant nowadays. The qualitative development of competitive advantages among domestic enterprises of instrument-making and engineering is possible nowadays mainly due to the effective use of available resources, the faster growth of labor productivity and enterprise innovative activity increase. At that it is important to pay a special attention to the development of an effective mechanism for innovative project competitive portfolio of production design and technological preparation (PDTP), since it is the quality, the duration and the cost of PDTP that largely determine the innovativeness and financial profitability of products. The article presents an economic-mathematical model of production capacity optimization, which allows to increase the efficiency of labor resource use and to optimize the time of new product development at machine-building enterprises (the load model for interchangeable resource groups). The model aims to minimize the total cost of documentation development, subject to simultaneous loading of employees in several projects within the matrix management structure. Thus, the competent planning of project portfolio financial efficiency concerning design and technological preparation in the modern dynamically developing world is one of the main attributes for a successful innovation and investment policy of an enterprise. The calculation of the proposed model serves the strategic and the tactical goals of an enterprise: it is necessary during the change of project participant composition and number and should be taken into account during personnel policy and enterprise overall strategy development.
