The article solves the problem of developing two coordination algorithms for managing large-scale projects. The first algorithm is designed to select the appropriate method of coordination when managing the projects under consideration. The algorithm is based on the thesis that the higher the threat of failure of the project plan, the higher the degree of centralization of project management should be, and the lower the threat, the less centralized the project management should be. With this approach, choosing the appropriate method of coordination actually comes down to assessing the threat level. Given that the concept of “level” is of a qualitative nature, it is proposed to characterize it by the function of belonging to gradations: “very high”, “high”, “medium”,” low”, and” zero”, and to evaluate the current threat level, use the measure of hemming proximity, which uses the zero threat level as a reference. The second algorithm is designed to select optimal coordinating solutions based on the criterion of minimum deviation of the project from the specified target state. Its novelty and originality lies in the fact that, unlike the usual optimization approach, it is built on a combination of methods of full iteration and linear programming. This made it possible to correctly take into account the fact that coordinating and design solutions are inextricably linked with each other.

MULTI-ASPECT ASSESSMENT OF THE QUALITY OF PROJECTS TO ENSURE THE ENVIRONMENTAL SAFETY OF CONSTRUCTION PROCESSES

The article solves the problem of multi-aspect assessment of the quality of projects to ensure environmental safety of the complex of construction processes performed during the construction of buildings and structures. A system of quality criteria for projects of this type is formed, including one integral criterion and four complex criteria that characterize projects in terms of their relevance, feasibility, economic feasibility, realism, and twenty-six local criteria. All criteria meet the requirements of adequacy, completeness and sensitivity. They are systemic in nature and cover the main aspects of environmental safety of construction industries. Based on the use of multiplicative, additive, metric and dichotomous convolutions, formulas are written for evaluating the integral and complex quality criteria of projects to ensure the environmental safety of construction processes. An algorithm for multi-aspect assessment of the quality of projects of this type based on the use of these formulas is developed. The implementation of this algorithm in the practice of territorial environmental authorities will solve a number of topical issues, namely: to improve the quality of expertise of projects to ensure the environmental safety of construction processes; to encourage the introduction of digital technologies in the practice of organizing construction work; to unify legal, economic and technical mechanisms to encourage the introduction of “green” technologies in the work of construction organizations.

Keywords: construction, project, environmental safety, assessment, criterion, algorithm.

RESOLVING CONFLICTS OF INTEREST BETWEEN CONSTRUCTION PROJECT PARTICIPANTS BY OPTIMIZING RESOURCE ALLOCATION

The problem of resolving conflicts of interest between participants in construction projects by optimizing resource allocation is Considered. In contrast to the traditional optimization approach, which often does not provide a solution in conflict conditions, it is proposed to use a complex Nash-Pareto criterion. In this case, the conflict of interest is resolved, since it becomes unprofitable for project participants to overestimate their resource requirements, and their resource needs are met to the maximum extent possible. A mathematical formulation of this problem is given, and based on V.N. Burkov, D.A. Novikov and Y.B. Germeier, is her decision. We consider two types of models for Nash-balanced resource allocation between project participants: direct and reverse priority. In the first case, the resource is distributed according to the principle: “more you ask – more will be given”, in the second – “more you ask – less will be given”. For these models, their varieties are distinguished: simple, taking into account the resource utilization coefficient, with a fine and with an incentive. For all types of models and their modifications, formulas are written to determine the resource allocation plan. The article describes an algorithm for resolving conflicts of interest between participants in construction projects by optimizing resource allocation, based on the above models and the results of their analysis. A distinctive feature of the algorithm is that the settlement of the conflict of interests of participants is supported by the search for Pareto-optimal resource allocation plans. As a discussion of the results, we consider a task where several types of resources are distributed, rather than one. It is shown that taking into account the integration of supplies and interchangeability of resources of different types, such a problem can be reduced to solving a problem for one type of resource, and the conflict of interests can be resolved using the proposed algorithm.

TYPOLOGY OF RELATIONSHIPS BETWEEN CONSTRUCTION PROJECT PARTICIPANTS IN THE INTERESTS OF RESOLVING CONFLICTS OF INTEREST BETWEEN THEM

A typology of relationships between participants in construction projects is given, aimed at resolving conflicts of interest between them. It differs from the known typologies of “common sense” in two ways. First, it is based on taking into account the formal factors of functional, resource and managerial nature that take place in the process of implementing projects of this type. Secondly, it reflects the main features of modern construction projects, namely: their pronounced economic orientation; the presence of resource, social, environmental, historical, cultural, and other restrictions; the structural complexity of the organization of a team of performers with conflicting relationships between them; a wide range of used construction, communication, fire, environmental, and other technologies. As a result of the study, a scheme is presented that identifies 16 types of possible relationships between participants in construction projects grouped by functional, managerial and resource characteristics. This typology can serve as a starting point for solving the problem of rational organization of construction work in the context of a conflict of interests and has the applied value that opens the way to the construction of mathematical models and computer software for decision support in the search for compromises between conflicting participants in construction projects.

Keywords: construction, project, conflict of interest, relationships, typology, functions, resource, management.

ANALYSIS OF APPROACHES USED FOR PROJECT MANAGEMENT IN ORGANIZATIONS

The paper discusses the features of solving problems related to the processes of project management in organizations. The characteristics of companies using the project approach are given. The formulation of the problem associated with the choice of projects from a variety of alternatives is given. It is demonstrated how the characteristics of the projects are evaluated. The strategy of the organization affects the maximum number of project options possible with the formed portfolio of projects. The methodology and approaches used in the process of evaluating the effectiveness of projects: the method of multi-criteria evaluation, linear programming model 0-1 Integer, integer programming model. In order to effectively manage project portfolios, it is proposed to select a set of parameters from the point of view of which there should be an assessment of projects and their portfolios in the process of deciding on the inclusion of projects in portfolios or in the selection of portfolios. Project optimization models in companies are based on the methodology of operations research. Through a combination of optimization methods and decision-making methods, you can select the desired set of projects that lead to maximum benefit. Restrictions in the formed multicriteria problem can be different, for example technological, resource.

Keywords: :project, management, project portfolio, optimization methods.
