        Analysis of recent research and publications
By a multi-project environment (MPE), we mean a set of projects that are not
necessarily functionally related, but use the same resources from the company's general
pool of resources. Multi-project management is a short-term tactical management of
many projects that share the same resources [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
      </p>
      <p>
        In papers [
        <xref ref-type="bibr" rid="ref1 ref2 ref3">1-3</xref>
        ] an analysis of approaches to human resource management in a
multi-project environment is presented. The criteria for the classification of
approaches were the degree of centralization, the degree of focus on human resources,
optimization algorithms. The main approaches are:
 Heuristic OR;
 Buffer management approaches like critical chain;
 Agile by using scrum of scrums;
 Multi-agent auction based;
 Resource sharing policies with dedicated and core teams and shared resource
pools;
 Systems management.
      </p>
      <p>As a result of the analysis, it was determined that, in most cases, approaches to
human resource management in a multiproject environment are based on automated
centralized decision making. The use of Agile Scrum, Scrum-of-Scrums flexible
methodologies will ensure decentralization and self-regulation, which is especially
important when managing projects in IT companies.</p>
      <p>
        The use of flexible project management methodologies has led to the need to solve
a number of tasks caused by the self-organization of teams [
        <xref ref-type="bibr" rid="ref4 ref5">4-5</xref>
        ]:
 changing resource requirements;
 engaging senior management in project-level sponsorship;
 achieving cross-functionality and effective team-level evaluations;
 the statement of independence and independent assignment of resources at the
individual level;
 lack of eligibility criteria and dependencies at the task level.
      </p>
      <p>Resource management in a multi-project environment includes planning, distributing,
balancing and coordinating resources in individual projects, as well as resolving
resource conflicts between different projects in order to achieve an optimal allocation of
resources between projects in a multi-project environment.</p>
      <p>
        The use of Critical Chain Method (CCM) for multi-project resource management is
based on the assumption that resource constraints between different projects mainly
occur in the critical paths of projects that form a multi-project environment. The
redistribution of resources in this approach occurs in accordance with the priority of
each project. To prevent delays in performing work that lies on a critical path, it is
proposed to use a resource buffer [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ].
      </p>
      <p>
        Within the framework of promoting sustainable use of resources in business
organizations (Green human resource management) and ensuring environmental
sustainability, additional requirements are put forward for project teams: high level of
technical and managerial skills among collaborators, environmental values,
environmental interests of stakeholders. Accounting for these restrictions in the formation of
teams (Green selection) will provide further induction and improve the efficiency of
the organization [
        <xref ref-type="bibr" rid="ref7 ref8">7-8</xref>
        ].
      </p>
      <p>
        When forming Agile teams, it is necessary to take into account factors [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]:
 competences (availability and level);
 team climate;
 team variety;
 team innovation;
 characteristics of team members: technical and personal competencies of team
members;
 presence of corporate culture;
 values;
 group leader behavior;
 top management support: project management commitment;
 emotional intelligence;
 communication skills.
      </p>
      <p>
        Additional requirements for the project team can be formed when identifying risks
[
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Risk identification will allow to take into account the need to ensure the reliability
of the project team’s operation by introducing redundancy into teams and forming
functionally-reserved teams.
      </p>
      <p>
        According to the Standard for Portfolio Management, PMI, human resource
management is responsible for maintaining the right balance of staff and competencies
based on strategic plan drivers and market pressures [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ].
      </p>
      <p>The use of competence-based approach in the formation of the project team
[1115] allows to provide the required level of competence in the teams formed.</p>
      <p>
        The adaptability of the team leads to the ability to respond to changes in the list of
currently available business requirements and technical requirements for the project
and its product [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ].
      </p>
      <p>Since the stakeholder-oriented approach in determining the success of a project
(maximally satisfying the expectations of stakeholders) is typical for managing a
portfolio of projects, human resource management in a multi-project environment implies
finding a balance of interests of the stakeholders in human resource management
processes and a compromise that ensures the achievement of the company's strategic
goals [16].</p>
      <p>In order to automate the decision-making process when choosing a project team, a
number of authors propose to use the decision support system for choosing a project
team [17].</p>
      <p>Isolation of previously unresolved parts of a common
problem. Objective
The application of the considered methods allows to form project teams, but does not
take into account the need to apply an integrated approach in the management of
human resources in a multi-project environment. Actual scientific problem is the
development of theoretical foundations and tools of human resource management software
in the formation, development and management teams of the projects and programs.</p>
      <p>The purpose of this article is to create models and methods of project-oriented
resource management of the formation of adaptive teams in a multi-project
environment.</p>
      <p>The article solves the following tasks:
 creation of a model of project-oriented resource management in a multi-project
environment;
 development of methods for determining human resource management strategies in
a multi-project environment;
 development of a method for stakeholder-based human resource management of
projects in a multi-project environment;
 development of a model for the construction of a functional-redundant adaptive
team.</p>
      <p>In the study, system analysis was used to formalize the processes of formation and
functioning of project teams, the apparatus of optimization theory for formulating and
solving the tasks of forming teams of projects in a multi-project environment under
given constraints, Boolean algebra and set theory to solve problems of forming teams
and redistributing resources.

        Model of project-oriented resource management in a multi-project
environment
A model of project-oriented resource management in a multi-project environment
(Fig. 1) has been developed, reflecting the relationship of the proposed methodology
with project resource management processes (PMI PMBoK), program resource
management (PMI The Standard for Program Management), project portfolio resource
management (PMI The Standard For Portfolio management) [
        <xref ref-type="bibr" rid="ref10">10, 18-19</xref>
        ].
      </p>
      <p>Defining a strategy for managing human resources in a multi-project
environment
Strategic human resource management in a project-oriented organization is aimed at
achieving a strategic alignment of the organization’s intentions and plans concerning
the strategy, policy and practice of human resource management of projects (hiring,
searching and selecting employees, building project teams, managing resources in a
project portfolio, training and development, motivation) [20].</p>
      <p>Depending on the company implementing the portfolio of projects, leadership
style, human resource management strategies can be distinguished [21]:
 resource oriented management;
 high performance management;
 management focused on a high level of commitment;
 participatory management.</p>
      <p>Since human resource management in a multi-project environment is associated with
the influence of certain project stakeholders, the project portfolio, the project
organization as a whole, the definition of a coherent human resource management strategy is
an important task affecting the efficiency of project implementation and ensuring the
viability of the company.</p>
      <p>When determining the strategy of human resource management in a multi-project
environment, it is proposed to apply a set of methods:
 a method for analyzing the assessment of human resource management processes
in the basis of strategies, a method for adapting the strategy of a project-oriented
organization to exogenous changes [22];
 a method for analyzing the consistency of priorities [23];
 a method for assessing the loyalty of stakeholders in resource management
processes [24].</p>
      <p>The use of the stakeholder model for analyzing the stakeholders of the human
resource management process [25] allows identifying stakeholders, determining their
interest in managing human resources, and evaluating their loyalty.</p>
      <p>Each project process that is executed in a multi-project environment is
characterized by:
 belonging to the project (Pr = {Pr1, …, Prn}, n is number of projects implemented
in a multi-project environment);
 indicator value of resource management processes in a project LSi,j (showing the
level of the j-th process in the i-th project);
 criticality Ki,j (the number of critical factors influenced by the jth process in the i-th
project).</p>
      <p>According to the PMI PMBoK standard, multiple resource management processes for
the i-th project can be represented as follows:</p>
      <p>Pi={Pi,1, Pi,2, Pi,3, Pi,4, Pi,5, Pi,6},
(1)
where Pi,1 – resource management planning;</p>
      <p>Pi,2 – resource assessment operations;
Pi,3 – resource acquisition;
Pi,4 – team development;
Pi,5 – team management;
Pi,6 – resource control.</p>
      <p>When constructing a stratified representation of resource management processes in
a multi-project environment, it is proposed to use a three-dimensional coordinate
system (system cube) that reflects the achievement of a specific resource management
strategy in projects running in a multi-project environment (Fig. 2).</p>
      <p>An analysis of the projections of the stratified representation of human resource
management processes in a multi-project environment allows us to determine the
direction of development of the processes, as well as identify the processes that need
improvement (Table 1).</p>
      <p>Based on the result of the analysis of projections, a change vector is formed, which
can be used in the reengineering of human resource management processes.</p>
      <p>Method of stakeholder-based human resource management of projects in
a multi-project environment
Accounting for the relationship of resource management processes with the processes
of management of stakeholders in project management in a multi-project environment
can improve management efficiency by reducing the risks associated with the human
factor [24-25].</p>
      <p>Stakeholders of resource management processes in a multi-project environment
can be company executives, human resources director (ensures availability and
availability of qualified human resources for managing a portfolio and its components),
individual project managers, investors, customers, etc.</p>
      <p>When managing a project portfolio, the stakeholders are [15]:
 supreme management body of the company, making strategic decisions on the
development of the company's portfolio;
 portfolio management team;
 director of the portfolio;
 portfolio board;
 managers of programs;
 project managers;
 program / project office;
 program / project teams;
 customers;
 suppliers and partners.</p>
      <p>The director of the portfolio, along with the analysis of financial indicators,
performs an analysis of the availability of resources necessary for the implementation of
the portfolio components.</p>
      <p>The proposed method of stakeholder-based human resource management projects
in a multi-project environment.</p>
      <p>The main stages of the method:</p>
      <p>Stage 1. Identification of stakeholders in the human resource management process:
 identification of stakeholders for each project;
 determining the projection of stakeholder interest on project management
processes;
 identifying the stakeholders of the project's human resource management process
and determining their interest;
 determining loyalty of interested parties;
 formation of stakeholders' expectations from the process of human resource
management.</p>
      <p>Stage 2. Formation of generalized requirements for project resources in a
multiproject environment:
 formation of requirements for project resources;
 consistency check;
 formation of requirements for project portfolio resources;
 defining critical competencies;
 formation of a pool of critical competencies;
 checking resource availability.</p>
      <p>Stage 3. Formation of adaptive commands:
 formation of adaptive teams with given resource requirements and constraints
(reservation, prohibition on combination, prohibition on participation in projects,
preferences of stakeholders, cost, etc.);
 consideration of adaptation;
 optimization by specified criteria;
 selection of command options.</p>
    </sec>
    <sec id="sec-2">
      <title>Stage 4. Team activity analysis:</title>
      <p> changes analysis;
 requirements update;
 team adaptation.</p>
    </sec>
    <sec id="sec-3">
      <title>Stage 5. Correction:</title>
      <p> resource pool correction;
 correction of the pool of critical competencies;
 correction of the register of stakeholders.</p>
    </sec>
    <sec id="sec-4">
      <title>Stage 6. Stakeholder satisfaction analysis.</title>
      <p>Depending on the chosen strategy of human resource management, there is a
choice of criteria by which candidates are selected and a project team is formed.</p>
      <p>
        To minimize the impact of resource constraints, it is proposed to use redundancy
(as an alternative to the resource buffer). The formation of adaptive project teams
with functional redundancy was considered in [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ]. Under the functional reservation
understand the ability of several performers to perform a specific function. The
redundancy factors determine the minimum required number of performers capable of
performing this function to ensure the implementation of the project.
      </p>
      <p>The use of functional redundancy in the project will lead to the fact that a specific
executor will be assigned to perform a specific function. The reserve for this function
will be allocated to the execution of other functions, so that, if necessary, it can be
reassigned to the performance of the function. Depending on the existing restrictions
allocate "cold" and "hot" backup. In case of "cold reservation", the reserve is entered
only if necessary and some time should be taken into account for the redistribution of
the project team. The use of a "hot reserve" minimizes the time to put in a reserve, but
it leads to an increase in the staff of the project, an increase in the budget of the
project.</p>
      <p>The model of the process of building a functional-redundant team is shown in Fig.

      <p>Resolving the task of redistributing resources is based on the use of the
donoracceptor approach. Donor-acceptor resource interaction in a multi-project
environment is due to the presence of a single pool of organization resources, within which
there is a redistribution of resources between the work of donor projects and acceptor
projects [27].
