Parametric Models of the Product Novelty Assessment Through the Basic Structures Approach

The Achievement of essential consumer parameter values or the implementation of new functionality determines the degree of novelty of the product. However, issues related to the evaluation of technical and scientific novelty of experimental products remain open. This is due to different approaches in the formulation of the problem in terms of many parameters. One of the known approaches to quality assessment is the formation of options based on the basic structures. This approach is consistent with the practice of creating a new product based on a retrospective analysis of the basic structures in the selected problem area. Known, for example, models of functionally necessary and functionally sufficient structures, basic structures represented by the point of the multidimensional parameter space. An important complement to this approach is to take into account the constraints required to manage the quality of an innovation project. The process of improving the parameters of new products is halted by the existing limitations, both in scientific and technological progress and in the social environment. The paper proposes to determine the degree of change in the technical characteristics of new products in relation to the current analogue or adopted prototype. The set of technical and social requirements established for the product by the terms of technical requirements and normative documents determine the functional significance of new products. Models and methods of estimation of a product novelty achievability in the conditions of not completely clear requirements of the market are offered. The analysis of the degree of change of parameter values is performed using fuzzy logic and flexible calculations. The parametric model application allows, taking into account the existing limitations, to determine the required level of perspective novelty of products.
