        Traditional approaches to project and program management are based on the
implementation of relevant methodologies (PMBOK, PRINCE 2, Agile and etc.) and
information technologies (MS Project, Oracle Primavera, Clarizen, Trello and etc.)
[
        <xref ref-type="bibr" rid="ref1 ref10 ref2 ref3 ref4 ref5 ref6 ref7 ref8 ref9">1-10</xref>
        ]. When there is a need to extend the management horizons to the projects and
programs portfolio (PPP), the problem of adapting the above-mentioned
methodologies and technologies to the conditions of PPP management arises. An even greater
problem arises when the operational processes of the enterprise are interwoven with
the project ones [
        <xref ref-type="bibr" rid="ref11 ref12 ref13">11-13</xref>
        ]. Then none of the above methodologies, like any software
tool, can solve this problem.
      </p>
      <p>For example, often project-oriented enterprises produce components, details, which
are then used in their own projects. For example, in aircraft engineering, each aircraft
can be considered as a separate project. Especially when customers are different and
require different modifications. On the other hand, such enterprises produce
components, units for their own aircraft. And here it is very important to integrate the
operational and project activities.</p>
      <p>Another problem of modern project management is that usually in enterprises for
project management various software tools are used to solve various functional tasks:
scheduling, control, economic and financial evaluation, etc. Traditionally, the tasks of
information integration in such systems are considered in the ways of managing
information communication in projects. But with the increase of the level of
projectoriented enterprises informatization, the use of various information systems (IS) to
solve functional problems is not sufficient. This task becomes even more complicated
when it is required to manage large-scale programs or portfolio projects and
programs. New challenges emerged - coordination of activities, allocation of resources,
prioritization of projects and programs, formation of teams, performance of
production or managerial functions of the enterprise not in the context of individual projects,
but on the portfolio as a whole.</p>
      <p>The lack of systems that provide effective management of enterprises, projects,
programs and project portfolios leads to ineffective management decisions,
unnecessary work or uncoordinated implementation, losses, major contract failures, and
numerous problems.</p>
      <p>To solve this problem, it is necessary to transfer some of the functions that are not
implemented by the software tools in a certain functional environment - the functional
add-on of these tools. And develop a software and information system that will
implement functions that are not reflected in the tool software both in terms of the
operational and in the context of the project activity of the enterprise.</p>
      <p>Proceeding from this, the task of creating a unified functional environment for
managing projects, programs, project and program portfolios and a project-oriented
enterprise (4P-environment), which would include tools involved both in the project
activity and in the operational activities of the enterprise, is at the forefront and
provided a systemic (synergistic) effect from solving a set of tasks of managing
portfolios of projects and programs as a single system of functions.</p>
      <p>Functional 4Р-environment of project and operational
processes</p>
      <p>The main purpose of the functional 4P-environment is to implement the functions
of managing the project, program, portfolio and project-oriented enterprises, in terms
of project activity. But the main resource of management functions is the information
needed for such management. Therefore, we can say that the functional
4Penvironment "immersed" in the information space, which provides the necessary
information.</p>
      <p>In general, the information space contains all the information that is needed to
manage it. First of all, it is the knowledge of managers and specialists, the knowledge
of senior management regarding the strategy and goals of realization of
projectoriented businesses, performance indicators of the enterprise, its financial status and
logistics, project and technological documentation, feasibility studies, estimates,
financial calculations, project charters and project management plans, project plans,
risk management measures, need for logistical resources and services, and
procurement plan, etc.</p>
      <p>All this information is an information resource of the project-oriented enterprise.</p>
      <p>The issue of information resource management (hereinafter referred to as IP) is
very important from the point of view of building a 4P-environment, as it will cover
the information network needs of all functions of this environment. The introduction
of 4P-environment allows to solve this problem. In this environment, information
resource is considered not only as a source of implementation of functions, but also as
an object of management. After all, in 4P-environment management functions are
performed by the software-information environment of modern computers using the
information that is fed to the input of such functions.</p>
      <p>
        Definition 1. A functional 4P-environment (or simply 4P-environment) is a
systematic set of functions of management of project, programs, project and program
portfolios, and a project-oriented enterprise (in terms of project, programs, and
portfolios management) that use a single information resource and provide a systemic
(synergetic) effect from solving a set of tasks of management of project-oriented
businesses of enterprises (fig.1) [
        <xref ref-type="bibr" rid="ref14 ref15">14-15</xref>
        ].
      </p>
      <p>As can be seen from figure 1, some of the project / program / portfolio
management functions are implemented with modern project management tools, some with
different information systems. And part of it is performed by employees of the
enterprise without the use of specialized programs. For example, when budgeting an
enterprise, information is collected from both projects and units that carry out operational
activities. Modern project management software tools do not allow to form the
enterprise budget (in the part of project implementation) according to the standards adopted
by the enterprises. That is why most of the enterprises have to combine all the
information on individual projects and operations into a single spreadsheet, using the
wellknown MS Excel office product.</p>
      <p>To solve this problem, it is necessary to migrate some features not implemented by
the toolkit to some functional add-on on these tools. And to develop a
softwareinformation system that will implement functional operators for functions that are not
reflected in the tool software. Such a software-information system can be created both
by the tools of the software systems themselves, as well as by ordinary means of
programming.</p>
      <p>Unlike enterprise resources planning (ERP) systems, where enterprise resource
management capabilities are supplemented by project management modules, the
creation of a functional 4P-environment consists of complementing the software tools for
project management by functions that enable them to integrate with both the processes
of portfolio projects and programs management, and with the management processes
of the project-oriented enterprise themselves. This, on the one hand, will reduce the
cost of project management tools and on the other hand, will increase their functional
completeness.</p>
      <p>The scientific and methodological basis of construction of 4P-environment is
necessary in order to create structures, algorithms, tools and processes of functional
addons over project management tools at project-oriented enterprises on the basis of the
developed models and methods. In fact, such a basis will create many functional
operators that will satisfy the need for project management in modern management
information technology.</p>

      <title>The practical Side of the Problem</title>
      <p>
        Solving the task of creating a unified functional environment for managing
projects, programs, project and program portfolios and a project-oriented enterprise could
be solve by exist information technologies of project management. Today, the Oracle
Primavera [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ] is the most complete in the functional sense according to the set task.
But authors had a practice experience of implementation of Primavera in a
projectoriented production enterprise that produced light aircrafts and there the next issues
were raised:
      </p>
      <p>1. It was necessary to do about 2700 operation for creation production enterprise
product. As far as there was a necessity to manage the projects and the production it
was necessary to put all these operation into Primavera database. Also, links between
operations should be set, and resources assigned to tasks. Wherein it was produced in
parallel a few products that shared the same labor resources. As the result it was
obtained a complicated and hard manageable project portfolio schedule plan.</p>
      <p>2. There was a big variance in order of resources production and so it was able to
use different optimizations models for schedule plan, but it was impossible when
project plan was created by hands.</p>
      <p>3. Constant changes in project portfolio lead to changes in portfolio schedule plan
which was pretty hard make by hands. For example, CEO decided to change priorities
and there became situation when it was needed to push one product forward and the
schedule plan was changed pretty much and these changes demanded a hard work.</p>
      <p>4. Often details were produced not one by one but by packages. This helped to
reduce time wasted for equipment setup. As the result part of produced resources were
sent to warehouse. These resources were used in the next products and did not have to
be produced again. Information about warehouse contained in accounting system.
And for quality planning there was necessity to exchange information between
Primavera and accounting system.</p>
      <p>5. It was unclear in Primavera project model how to manage resources which
change their state.</p>
      <p>6. It was necessary to manage procurements in project portfolio and often it is
convenient to group purchases from different projects. Also, there was needed to
purchase resources in advance. The time for purchase depended of resource. It was tricky
to manage such things in Primavera.</p>
      <p>So, such software as Primavera did not cope with the task to project and production
management of the enterprise. There was presumed that with MS Project and the other
similar products there will be similar problems. Considering this there was a variant to
implement ERP system, but after marketing analysis it was defined that ERP system
have a weak project management module and these class of system also can solve all
planning issues and as result can’t be used for management of project and production
activities of the enterprise.</p>
      <p>
        And as a solution it was decided to develop add-ons for Primavera. And in the
process of development it becomes clear that easier would be develop an independent
information system that add-ons for Primavera. Such information system should allow
to manage resources like an ERP system and manage projects like Primavera and will
connect information systems are involved in project and production activities. But
creation of the such system was needed some theoretical base – methods of project
and operating processes integration in the activities of project-oriented enterprises
based on functional 4Р-environment [
        <xref ref-type="bibr" rid="ref14">14</xref>
        ].
      </p>
      <p>4</p>
      <p>Method of Integration of Project and Operational Processes
in the 4P-Environment</p>
      <p>To solve the formulated tasks a method of coordination of project and operational
processes in the 4P-environment is proposed. It is based on simulation of operational
and project processes, with the choice of an order of material resources (MR)
production, which shortens the execution time of all projects</p>
      <p>1
where
m lm (RmT )
 m → max (1)

pool of work resources for the project Пm;
priority (importance) of the project Пm;
duration of the project Пm, if a resource RmT is
allocated to it.
with constraints:
- resource pool;
- technology of project execution.</p>
      <p>1. Of course, when in the project thousands of MRs are produced at different
stages of its implementation, it is impossible to optimize the allocation of resources.
Therefore, the method will be based on the accumulation of information on the
various stages of the decision making, followed by an assessment of the results of the
projects and the statistical determination of the influence of this solution on the
results. This is the intellectual part of the method.</p>
      <p>2. The description of resources in this method will also be different from the
traditional, performed in the means of the project management. Resources in the method
for coordinating project and operational processes in 4P-environments are described
by a tree. Which shows the occurrences:</p>
      <p>MR→Detail→Assembly→Subproduct→Product</p>
      <p>At each stage, the production of a higher-level resource from the lower-level
resources takes place. And they can be used in various projects.</p>
      <p>3. Each detail is characterized by the minimum quantity included in the kit. For
example, washers are produced in quantities of 10 units or greater.</p>
      <p>Stages of the method of coordination of project and operational processes in
4Penvironment:
1. Formation of scheduled network diagram (SND) of projects.</p>
      <p>2. Formation of operational processes for producing details, assemblies,
subproducts and products.</p>
      <p>3. Attachment of operational processes to the works of the SND.</p>
      <p>4. Setting the initial simulation conditions (time of modeling, use of the
intellectual block, constraints on resource allocation and product producing).</p>
      <p>5. Setting the model number n = 0.
6. Check if the simulation time has expired. If so – go to the end.
7. Increase the model number: n = n + 1.
8. Setting the start time of projects t = 0. Cleaning the SND from execution.
9. Verify that all the work is done. If so, go to item 6. If not, increase in the time
of execution of projects for 1 day: t = t + 1.</p>
      <p>10. Selection of SND works for which fulfillment conditions are fulfilled
(available resources and completed / missing work-predecessors).</p>
      <p>11. If the set is empty go to item 9.</p>
      <p>12. Random selection for work on its priority. The priority and probability of the
selection is calculated as follows:
12.1 For each pair of works the priority coefficient is calculated:
 (Wkj / Wmi ) =
 (Wmi / Wkj ) =</p>
      <p> (Wmi / Wkj )
 (Wmi / Wkj ) +  (Wkj / Wmi )</p>
      <p> (Wkj / Wmi )
 (Wmi / Wkj ) +  (Wkj / Wmi )
(2)
(3)
 (Wmi / Wkj ) + (Wkj / Wmi ) = 1 (4)
where  (Wmi / Wkj ) – priority coefficient of the work Wkj of the project
Пk relative to the work Wmi of the project Пm;
 (Wmi / Wkj ) – priority coefficient of the work Wmi of the project
Пm relative to the work Wkj of the project Пk;
 (W j / Wi ) – apletneranltaytivoen wmoordkeslsw,ienrewwhiocrhksinWthmie amndultWit ukjd,eanodf

 (Wi / Wj ) – apletneranltaytivoen wmoordkeslsw,einrewwhoicrhksinWtmhieanmdultWitukjd,eanodf
here work Wmi was chosen.</p>
      <p>12.2. Model penalty is calculated as the sum of the difference between the target
project finish and the finish obtained in the model</p>

      <title>Conclusion</title>
      <p>For today production enterprises has specific features in business processes,
organizational structure and etc. which should be included when project management
system is implemented and traditional methodologies and information technologies of
project management not suitable for management of project and production activities
of the enterprise, because these systems could not support all processes of project
resource management and a lot of information is lost in project management
processes.</p>
      <p>In the paper it is shown that the main purpose of the functional 4P-environment is
the implementation of project management functions / programs / portfolios and
enterprises, in part of the project activity, which are not available in instrumental
software tools. The method of coordination of project and operational processes in
4Penvironment is developed. The basis of the method is the simulation of the producing
process of components for the work of the project with the selection of time and
number of MR, which allows minimizing the time of portfolio projects execution. The
method allows to combine project and operational processes into a single
management system on a project-oriented enterprise, which in turn reduces the timing of
projects, organizes operational activities, optimizes the allocation of resources.</p>
