The authors suggest the models of competitiveness assessment of engineering products at the early stages of the product life cycle. The criteria-based approach and the machinery of fuzzy sets theory are applied when developing the models. The model of consumers’ preferences forecasting allows calculating the prospective demand, motivation of consumer behavior, their attitude to the supplied product. The model based on the pair-wise comparison approach calculates fuzzy sets of various degrees of product competitiveness. The model of engineering product rating ensures rational selection of alternatives under the conditions of collective selection at all stages of the product life cycle.

The Creation

The shortcomings of the traditional description of the engineering product are shown. It is proposed to represent the design of the product and its details with a structured set of corresponding modules, in the form of a graph of a hierarchical structure. The characteristics of the structure of the product graph are considered: the number of levels, nodes, branches. The description of the structures of products by a hierarchical graph at the first level makes it possible to identify functional technological modules of the products and, on their basis, to construct a unified classification of products as objects of exploitation. Representation of parts by a set of modules allows you to identify modules based, working and connecting surfaces and on their basis to build a single classification of parts, focused on different stages of the product life cycle. The presence of a unified methodological base allows you to manage the development of product designs, minimize duplication in the creation of new designs and effectively develop technologies for their manufacture.

The shortcomings of the traditional description of mechanical engineering product are shown, which are based on technological features oriented to single, typical and group operations of the technological process. It was proposed to represent the design of product and its parts with a structured set of relevant technological modules, in the form of a graph of hierarchical structure. The numerical characteristics of the structure of the graph of product, its levels, nodes, branches are considered. The description of the structures of products by a hierarchical graph at the first level makes it possible to identify the functional technological modules of products and, on their basis, to construct a unified classification and to suggest coding products, both for production objects and operation. Representation of parts by a set of modules allows identifying surface modules, working and binding, and on their basis to build a single classification of parts focused on different stages of the product life cycle. The presence of a unified methodological base allows managing the development of constructively complex products, minimizing duplication in the creation of new designs and effectively developing resource-saving technologies for their manufacture.
