Sergii Stetsenko et al., International Journal of Emerging Trends in Engineering Research, 9(2), February 2021, 60 – 65 60 ABSTRACT This article is devoted to the problem of introduction of artificial intelligence systems into the activity of building participants and other building projects stakeholders. An example of determination of a contractor inner potential by means of fuzzy sets is presented. It is recommended to contracting companies to accumulate information about the components of the competitiveness potential, specifically about: their activity diversification (concentration), resource efficiency (sales volume to company assets quotient), pricing policy flexibility (level of discounts at tenders), business reputation level – business assurance level of a company (percentage of works executed and paid under the won tenders in the total value of the won tenders). A model of determination of the influence of the indicated parameters onto the portion of the won tenders in the total value of the submitted tenders, which is based on fuzzy logic, is offered. Creation of an information system, which is presented in the form of a database, which accumulates information during the whole lifecycle of a company, is the following research direction. Key words: building company, building project, competitiveness, decision–taking systems, fuzzy logic means. 1. INTRODUCTION Nowadays advantages in competitive struggle do not depend very much on the sizes and resource provision of specific companies, because the scope and the level of mastering of information resources [1], knowledge, intellectual and digital components of development [2] come to the foreground. Building companies also actively introduce new software, decision–support tools and methods, artificial intelligence tools into their work. A series of scientific works is devoted to the issues of arrangement, designing, development and application of the systems, destined to process information, which are based on application of artificial intelligence methods. But the issues of application of the mentioned means in formation of anticrisis potential [3], economic immunity [4], development of building company management systems [5, 6], investment and building processes [7, 8], building organization and technology projects [9-12], inner and outer business processes of building stakeholders [13-15] stay of current interest. The contemporary building development stage requires not only introduction of digital technologies, but compatibility of software and data transmission formats within the scopes of interaction of the main building stakeholders as well from the participants of building. Further research and development are required within the scopes of interdisciplinary interaction of the systems of taking and support of managerial decisions, oriented at complex research of the building projects stakeholders’ competitiveness. Such systems have been created already for development companies [5, 6], but new methods of their utilization and search of new spheres of application are required, for example development of such systems for contractual building companies, which have differences from other participants of building.
