It is an important factor that tool size affects the quality and efficiency of complex curved surface of CNC machining. This paper starts with analyzing the functional relationship between the tool size and the quality and efficiency of complex curved surface, gives the selection method of optimal minimum tool which can ensure the precision of machining curved surface, establishes optimal selecting algorithm of reasonable large size tool with the most high efficiency as the objective, and for the curved surface of complex geometric features, puts forward tool combination selection method with effective area ratio of tool machining as a reference. Application examples show: the optimal selecting strategy of tool size in this paper, under the premise of adequately ensuring the machining quality of complex curved surface, can effectively improve the whole machining efficiency.

Diversification of investment is an important part of corporate strategy. In this paper we studied diversified investment. Firstly, we made a classification of industries according to the growth potential. We also discussed the decision-making problems of industry combination in diversified investment with the aim of maximizing the growth rate-risk ratio. At the end of the paper, we put the case in power generation group as an example explanation. In the case, we found that power generation group bringing diversified investment into effect can achieve the goal of the group.

<p><em>The article, basing on the analysis of selected media texts with reference to narrative from the leading Ukrainian newspapers «Dzerkalo Tyzhnia» (Weekly Mirror), «Den» (Day), «Ukraina Moloda» (Young Ukraine) for 2016–2020, the semantic and content characteristics of the «narrative», «strategic narrative», «small narratives» nominations has established; the directions of the semantic realization of the meaning of the narrative and its possibilities in the process of international strategic communications aimed at both external and internal audience, are outlined. It is proved that the main task of a strategic, or national, narrative is a reasoned explanation to the state population and interested audiences of specific realities, intentions, plans; justification of certain directions of state activity aimed at partners, at opponents and those occupying a neutral position.</em></p><p><em>There are divided the spheres of use of different narratological nominations: in international communications and in scientific discourse, the conceptual foundations of state identity and international interaction are referred to as strategic narrative or grand narrative, in publicistic discourse the narrative nomination is used, more rarely – historical narrative, national narrative.</em></p><p><em>The scientific novelty of the research is that the focus is on the media aspect of the use of one of the key concepts of strategic communications and the role of the media in its implementation.</em></p><p><em>The main general scientific methods used in this article are descriptive and comparative ones, as well as analysis and synthesis. The following empirical methods were also used: solid selection method (solid selection method for allocation texts with the «narrative» lexeme; quantitative method of content analysis with elements of qualitative one – for characterizing the semantic of the «narrative» term).</em></p><p><em>The results of the study can be used in the complex research of the technology of international strategic communications and in the practical activity of specialists in international strategic communications, a new trend in Ukraine, which is currently under active institutionalization.</em></p><strong><em>Key words:</em></strong><em> international strategic communications, propaganda, narrative, strategic narrative, grand narrative, «small narratives».</em>
