The competent care of forest stands especially ones such as middle-aged and ripening forests and possibility of timely using the renewal felling by developed parameters could be contribute to the formation of forests from valuable species and form an additional volume of wood with specified technical characteristics of wood. The positive ways by using renewal felling: the removing the most overmatured spruce trees because the conditions are created for better growth of the more economically valuable part of the forest stand left for growing; conservation and preservation of the climate and protective functions of the forest and environment’s condition; creation of a technological structure of the cutting area. In this regard, the results of scientific work could be take into account for renewal felling by developing a strategy for forest management and forestry, making management decisions, planning and designing activities. The scientific results obtained in the framework of the study its good scientific basis for improving the structure of the forests of the European North, increasing their productivity, biospheric role of forests and profitability of the forest sector of the economy.

The description of an experimental automated system of semantic design of (machine-building) products is given. In general, the proposed process of product design is considered stepwise: 1) technical creativity, 2) compilation of expert descriptions of professional product subject areas, 3) automatic synthesis of structural and parametric product properties and, finally, 4) synthesis of product form. The article focuses on the implementation of the second and third stages. Screen forms with explanations of data entry are given. The second stage is performed by professional subject matter experts: designers, technologists, material scientists, strength and design specialists, etc. The corresponding ontological descriptions of the subject areas are compiled. It is assumed that this knowledge will be taken into account when synthesizing the structural and parametric properties of the designed products. The third stage of the technology is carried out by the engineer. His main task is to come up with a name for the product and match it with the main design concept. Additionally, he can adjust the data ranges entered in the ontologies. Such actions also increase the efficiency of the automated system, reducing the search space for permissible parametric properties of the product.
