Integrated organizational management system of a construction company engaged in industrial area redevelopment

. A large number of large industrial cities around the world are characterized by the presence of industrial sites in the Central part of the city and areas close to the center. A significant part of these zones have lost their relevance and are not used as production facilities, but function as rental businesses. The relevance of the study considered in this article is due to the need to create an organizational and technological model for the development of project documentation for the redevelopment of industrial facilities in the absence of Federal and regional programs in Russia that affect this area, as well as the lack of a regulatory framework for regulating the activities of project organizations that develop the above projects. The article deals with the General principles of developing an organizational and technological model that allows evaluating and optimizing the designer's activity when repurposing industrial objects, as well as aimed at improving the design processes of such objects. For scientific, methodological and system-technical bases of designing organizational structures of enterprises and organization of production processes of modeling re-profiling of industrial territories, it was necessary to solve the following tasks: study and generalization of foreign and domestic experiences of redevelopment of industrial zones; identification of actual problems in the design of redevelopment of industrial territories; study of factors that affect the effectiveness of the designer; establishing the degree of influence of the identified factors on the quality of the project documentation produced. The parameters and organizational principles described in the article are taken into account when re-profiling industrial objects in the urban environment of large Russian megalopolises.


Introduction
The organizational system of an entity engaged in an industrial area comprehensive redevelopment project is reviewed on the basis of information provided by the Customer and research work. Performance efficiency analysis and development of an appropriate organizational structure that would consolidate and coordinate the work of a large number of professionals employed by the company with a view of accomplishing the set tasks as scheduled, at the required quality level and within the established financial and other resources require review of the available documentation, collection of key information and ensuring conceptual interconnections in the form of strategic initiatives ( Figure 1).

Materials and methods
Preparation and implementation of an industrial area redevelopment project is an integrated and complex process to be divided into separate stages [1]. In this case, the project is understood as an entire set of redevelopment operations and all related activities. The project concept is amalgamation of its objectives; functional and space solutions as the core of the entire project; external environment of the project; project participants; distribution of tasks, responsibilities and risks borne by each of the participants. The company can be concurrently involved in several projects with similar characteristics (civil engineering, road construction, industrial construction, engineering infrastructure facilities). As a consequence, a unified organizational structure can be formalized by separating individual operations therein ( Figure 2).

Due to the fact that major facilities subject to industrial area redevelopment are hierarchically structured with different numbers of levels and different target functions (functional efficiency criterion), the most efficient solutions require multi-level and multiobjective systemic optimization with account of links in structural and functional subsystems [2]. However, the necessary assessment level for such links remains beyond the limits of comprehensive analysis due to the difficulties in processing large data volumes. However, recent years have been witnessing the development of new hardware, generation of automated data banks, systematization of statistical data on links in large multilevel construction systems, and the emerging possibility of fast analysis of large data volumes using supercomputers. As a result, systemic optimization of industrial area redevelopment projects can now be based on the necessary pre-requisites and conditions. In practice it can be implemented as follows [3].
Traditional objective-setting in organizational and technological structure optimization is reduced to identifying system parameters described by a mathematical model and relationships among elements as follows: where the objective function F would have an extreme value Here i = 1, ..., n is the number of elements in the system. The formation of analytical links among the multi-level system elements under review requires considerable labor costs [4]. It is a complicated exercise, which is not always expedient and is frequently impossible. It is much more efficient to create alternative options for the system elements, to assess them by a certain criterion, and then to create a system by integrating the selected elements, just as it is done in practice. In spite of such tolerances and simplifications, this challenge is still rather complicated and laborconsuming, but it can now be tackled by system analysis methods in the following order: 1) set an optimization goal; •Design and analysis of the sketch to decide on entry into the project Idea 2) identify individual system elements and all potential factors of influence on the final result; 3) create an alternative tree of goals, taking into account the greater variability across the hierarchy; 4) evaluate system optimization criteria for generating alternative organizational and technological solutions; 5) analyze the obtained alternatives in the targets tree and remove unnecessary options, leaving the key ones; 6) synthesize the system using the created goal tree and generate a solution to the problem as a whole.
The target function in the multi-criteria evaluation of an option of a certain level in the targets tree is as follows: In this case, the system criterion for all elements of n levels can be expressed as follows: Here k is the number of criteria; βi -weight coefficient; -criterion; m -number of options.
The entire search for alternative solutions and the comparison of the system criteria of options enables selection of individual elements of the target tree with the extreme values of the criteria, that is performing systemic multi-criteria and multi-level optimization and choosing the optimal solution [5].

Research result
Enhancing the efficiency of industrial area redevelopment projects requires new costeffective and innovative organizational and technological operational solutions. For this reason, the great importance is given to scientific, technical and economic forecasting in designing, information modeling, and construction and installation works for redevelopment of industrial areas, as well as practical use of these forecasts. Application of scientific forecasting makes it possible to carry out a preliminary assessment of the effectiveness of practical use of the proposed design, organizational and technological solutions and to improve the quality level of the project as a whole [6].
Design of the organizational and technological system is based on the use of management modules that characterize production, technical and technological relations in projects of renovation and redevelopment of industrial areas [7]. The organizational system of such macrostructure is required to: -Reflect the organizational, technological, and resource relations among individual components of the project; -Provide the planning basis for the whole set of operations within the company's projects; -Be flexible and responsive, quickly adaptable to possible changes in design solutions not affecting major structural elements or connections.
-Thus, the organizational structure of an industrial area redevelopment project that creates an integrated interconnection among basic modules and stages is formed into a unified organizational block.

Conclusion
Each of the major stages of the project is split into separate phases, which, in turn, are divided into specific tasks. Participants in the projects, each of whom has a certain function to perform in accomplishing project tasks, are selected in accordance with a variety of conditions and factors determined by the project objectives, its external environment, and project parameters. The system is based on the modular principle providing for identification and description of individual standard module processes. The modular structure of the project system allows to improve visibility, increase flexibility in planning, monitoring and possible adjustment of the entire project as a whole and its individual elements, as well as to simplify information flows throughout the entire construction system [8][9].
Organizational and technological modules are formed on the basis of: -Analysis of existing business processes; -Identification of the main problems of business processes and formation of proposals for local improvements; -Modeling of business processes and identification of controlled parameters; -Action planning for process implementation; -Management problem tackling algorithm; -Appointment of an officer responsible for each stage of the process. Appointment of a manager for each business process who will manage the process and the allocated -Systemic control of sequential execution. Development of process control elements. Specification of objectives, development of a scorecard and a parameter reporting system, types, forms and procedures for motivation of contractors and the owner.
The development of the organizational and technological system requires the following: -Preliminary division of the production process into stages; -Establishment of process modules; -Development of a reference system alternative with embeddable modules; -Modeling of organizational and technological system alternatives; -Calculation and selection of the optimal alternative. Further adjustment of solutions taking into account the dynamics of the external and internal environment of the project.
Structuring the production process of the project and highlighting its structural elements enables the creation of a visual model to be used as the basis for developing the company's organizational system. Building a company's organizational and technological system from modules and further use of individual modules based on established coordination and synchronization procedures is one of the most important principles for integrating construction phases in large projects.
Thus, building the organizational and technological system of an organization typically includes: -Identification of key activities by key factors; -Determination of tasks to be achieved in attaining the objectives of the selected key activities; -Creation of a value chain system integrating all the key activities into a logically coherent interaction business scheme; -Combining activities into lines of activity and selection of structural units responsible for lines and types of activity; -Schematic representation of the company's organizational and technological system ; -Regulatory action on the organizational and technological system. Formation of the company's organizational and technological system includes development of recommendations on changes aimed at significant improvement of efficiency of the company's operations, such as recommendations on: -Alterations in the management system; -Alterations in the management method; -Alterations in the project procedures; -Regulatory action on the functional procedures. The organizational management task is to create an information system that ensures effective monitoring of the project performance indicators, evaluation of the difference between their design and actual values, decision-making and possible adjustment, related coordination of interaction between project participants, creation, updating and transfer of the project information database, and its use in all structural elements of the project [10].
To ensure that the work of all project participants conforms to the contractual deadlines and costs and to achieve maximum efficiency of the company's activities thereupon, it is necessary to: Bring the changes to the notice of the staff of related subdivisions. The concept of development of an integrated industrial area redevelopment project is based on practical approaches to achieve the final outcome as shown in Figure 3 and includes: Coordination and cooperation of all project participants having a common goal, but individual tasks, interests and responsibilities; Formation of a flexible production management system providing for broad independence of the parties involved and strict control of intermediate and final performance indicators; The lowest possible loss of time for auxiliary routine procedures with clear organization of registration, storage and use of the information base at all management levels.
Forecasting in the field of redevelopment of industrial areas and justification and selection of optimal and promising urban-development options offering labor, financial, material and energy savings are possible subject to appropriate mathematical models and software. Forecasting, justification and selection of solutions are labor-intensive operations requiring significant labor costs and high skills of designers and can be implemented only in collaboration with process engineers.
Analysis of the company's organizational structure results in a uniform implementation algorithm for industrial area redevelopment projects (Figure 3). Thus, the rational structure of production processes and conformity to project solutions and requirements to hardware and skills are subject to a wider analysis of all company operations.
