MODELLING AS TRANSPORT SERVICE QUALITY AND EFFICIENCY INCREASE

The most important contribution to the solution of the main tasks of the country’s economic and social development is made by the successful operation of the transport infrastructure. The transport system provides conditions for economic growth, increasing national economy competitiveness and life quality of population. Transport organizations need to continually improve their operations in order to remain competitive. This requires the development of new technologies and methods for doing business, improving the quality of activities and introducing new, modern, effective methods of managing and organizing the activities of enterprises. Business process modeling makes it possible to understand the work and analyze the organization, as well as improve the quality and efficiency of the transport organization. The article discusses different ways aimed at improvement of efficiency and quality of transport organizations. The types of modeling used at transport enterprises are disclosed. Methods for business process modeling in transport organizations are presented. The recommendations of Russian Railways JSC are given in terms of improving the quality and efficiency for the following activities: freight services, freight and commercial services, maintenance of material base, infrastructure services, its maintenance and repair, services for the provision of freight cars, and their maintenance, services for the provision of locomotives and their maintenance and services for the repair of rolling stock. The authors have proposed an algorithm for assessing the efficiency of production processes in railway transport using the example of freight services.


Introduction
In the conditions of instability of economic processes, problems of economic development of the country, the issues of increasing the efficiency and quality of work of transport organizations are relevant, important for consideration and have high practical significance.
The following Russian scientists study the issues aimed at the efficiency increase of railway transport and quality assessment of transport services in market conditions, determining the main areas of

Problem Statement
Both efficiency and quality among transport enterprises are directly determined by competitiveness, which works according to the models, is more reliable, provides quality services, is more efficient and, as a result, is more competitive.
Thus, when assessing the quality of transport services, it is necessary to highlight such quality indicators as availability, efficiency, reliability, and convenience. To improve the efficiency of transport services, it is necessary to use reasonable indexation of tariffs and expand the range of provided transport services (Vasilenko et al., 2019).

Research Questions
The development of transport system, its efficiency, economic attractiveness and competitiveness are possible through the introduction of modern organizational and economic tools. One of these elements is a business process (Nesterov, 2011). The business process of Russian Railways is expressed in a set of goals aimed at producing services that are valuable to the consumer and obtaining the maximum positive economic effect from the provision of this type of service (Vasilenko et al., 2018).
There are many methods to improve the quality and efficiency of a transport organization. One of these methods is business process modeling. This method, allows to assess the current activities of the enterprise, is used to improve the efficiency and quality of work of transport organizations. The basis of this method is the description of the process through various elements belonging to the process under consideration. In modeling processes, they describe the logical relationship of all elements of this process from its beginning to its end (Bessmertny, 2016). https://doi.org/10.15405/epsbs.2021.11.219 Corresponding Author: Marina Vasilenko Selection and peer-review under responsibility of the Organizing Committee of the conference eISSN:  1661 Business process modeling involves the description of a process through various kinds of elements (actions, data, events, materials, etc.) inherent in this process, and makes it possible to describe the logical relationship of all elements of the process at all stages of its functioning within the organization.
The purpose of business process modeling in transport organizations is to classify information about organizations and the procedures within them. The use of methods for business process modeling is aimed at an increase of the operational efficiency of organization. In another words it is aimed at the arrangement of all processes in the best way possible, leading to lower costs and, at the same time, improved quality of products or services. In order to carry out this kind of optimization, it is necessary, first, to simulate the basic processes that occur on a daily basis in all divisions of the organization. The very idea of modeling business processes is expressed in the necessity for the manager and all employees to see all the activities of the enterprise from the inside and the possibility of seeing its outcome.

Purpose of the Study
When modeling business processes, it is very important to make a decision about the structure and content of modeling objects, to determine what elements the business process should consist of. Any sufficiently complex business process can include five main elements that should be reflected in the development of models, i.e. planning of activities, implementation of activities, registration of data, control and analysis, decision-making management (Skorodumov, 2014). Business processes modeling in transport organizations makes it possible to understand the work of the organization and conduct its analysis. The analysis carried out allows one to adjust the work of the organization in a more efficient way. Modeling has to be performed in more detail and multifaceted way, since it has a large number of cross-functional connections. To improve the modeling process in transport organizations, the types of modeling presented in Figure 1 are most often used.
Modelling types at transport enterprises https: //doi.org/10.15405/epsbs.2021.11.219 Corresponding Author: Marina Vasilenko Selection and peer-review under responsibility of the Organizing Committee of the conference eISSN:  1662 The listed modeling methods used to improve the quality and efficiency of transport organizations are designed to solve the most common transport problems (Yarlykova, 2016).
At Russian Railways' Quality Management Strategy the business process is represented by a set of various processes united within a certain type of activity (business), as a result of which a finished product is created that is of value to an external consumer. Improvement of the economic management of process quality affects all stages of management: planning and forecasting, accounting, analysis and control, regulation, and motivation. Detection of a defect leading to a failure at the initial stage will save significant funds, increasing the overall economic effect of the provision of transport services.
Transport organizations need to improve their operations in order to remain competitive. To do so, it is necessary to develop new technologies and business strategies, to improve quality of goods and services, and to introduce new effective methods of management and organization of enterprises' activities. Currently, computer-based media and software are used to model business processes at transport enterprises (Bessmertny, 2016).

Research Methods
Business processes modeling in transport organizations is performed using the methods presented in Table 1. 1663 Business process modeling at Russian Railways makes it possible to do the following: 1) To improve management and control of the quality of work at different stages, which is possible due to a good overview and understanding of all business processes of the company.
2) To understand what kind of employees and resources the company needs, which makes it possible to increase the efficiency of personnel selection.
3) To improve financial performance.
4) To apply a system of business processes to improve the quality and efficiency of work.

5)
To standardize processes (if you follow the rules for their implementation, you can achieve the desired effectiveness).
A clear description of all actions as well as workflow preservation allows one to standardize information or data about the organization and its operations in order to display everything in a graphical form later. Looking at the diagrams from the outside helps noticing the mistakes and think about how to avoid them.
Russian Railways is a large diversified company (Lapidus, 2004). The main activities, goals and processes carried out at Russian Railways are presented in Table 02. Forecast of the needs for repair and development of repair facilities; development of a plan and organization of railway rolling stock repair; management of the safety of repair works and the quality of repairs The following can be seen from Table 01: 1. It is advisable to establish a business process responsible for the implementation of carrier functions to increase the competitiveness of Russian Railways in the field of freight services, to strengthen the Company's position in the profitable and highly profitable segments of the freight services market, to ensure at least 50 % of the share of the Russian Railways fleet for each type of freight cars. should be defined the responsible persons for the corresponding functional area. At the same time, in the functional direction or area called "Customer" the following should be implemented: market monitoring, product mix policy, pricing (tariff) policy, contract work with customers, formation of a sales budget. As part of the "Process" direction there should be the forecast of the load of technical devices, determining the needs for their development and modernization, the organization of current activities and maintenance https: //doi.org/10.15405/epsbs.2021.11.219 Corresponding Author: Marina Vasilenko Selection and peer-review under  1665 of fixed assets, the development of requirements for material and technical means and the organization of their procurement, safety and quality management. The direction "Personnel" includes the business process provision with qualified workers to perform the functions assigned, training and retraining of personnel, social security in accordance with corporate standards. As part of "Finance" direction there should be established the organization of settlements under contracts with customers and under contracts with third-party organizations for the work and services performed by them. Preparation and contract signing, selection of a car, selection of a driver, determination of a route, terms and prices -all these are parts of an integral system of business processes for the delivery of a specific consignment of cargo to a specific location (Azarov et al., 2018).

Findings
The degree of sophistication and efficiency of the company's business processes directly affects the indicators of satisfaction with the goods and services of its customers (Sokolov et al., 2019).
Developing the most effective model of business processes focused on the end customers within the company is an urgent problem, both in international business and for domestic enterprises. Thus, the output or result of business process execution is always information, services or goods demanded by Customers. At the same time, a business process can have several outputs (Titova & Veinberg, 2011).
In 2020, according to the annual reports of Russian Railways, the main business process that brings the largest amount of revenue is freight service. An algorithm for assessing the efficiency of production processes in railway transport using the example of freight traffic is shown in Fig. 02. https://doi.org/10.15405/epsbs.2021.11.219 Corresponding Author: Marina Vasilenko Selection and peer-review under responsibility of the Organizing Committee of the conference eISSN:  1666 Algorithm for assessing the production process efficiency regarding railway transport using the example of freight services

Conclusion
The ultimate goal of business process modeling at transport enterprises is to improve the quality and efficiency of the organization as a whole. To achieve this goal, the analysis focuses on increasing the value of results and reducing the cost and time of processes.
