New information technology of centralized management of passenger car fleet
Vestnik of the Railway Research Institute
Steady requirements of consumers to the quality of to the development of automated systems, make it necessary to the information provided, on the basis of which the control actions constantly process or create higher quality products. The require-are carried out, as well as the acceleration of technical means related ment to improve the basic information solutions using modern technical resources offered by industry was the reason for the rework of the existing business process for managing the
... fleet of passenger cars implemented in the automated system for managing operation and repair of the passenger car fleet (ASUPV). The article gives a brief analysis of the 20-year work of the linear enterprises (LP) with the ASUPV - (ASUPV LP) subsystem, with the help of which the source documents are entered into the car park, trains are formed and the passenger car fleet maintenance is monitored. This subsystem is the main supplier of information for obtaining analytical data at all levels of passenger car fleet management. The article also outlines the main goal of the new information technology - obtaining, through single processing of primary data, new quality information, on the basis of which optimal management solutions should be developed. The purpose of the newly developed ASUPV LP-2 system is to automate the technological processes of centralized management of the passenger fleet of linear enterprises to improve performance and efficiency of the industry, which will allow optimizing the work of passenger line enterprises, monitoring compliance with technological processes and ensuring the availability of reliable information to interested users. The article describes the main tasks of the developed system: ensuring the need for the necessary and sufficient number of passenger cars for the fulfillment of the transportation plan at the linear enterprise; creating of guaranteed traffic safety of the formed passenger trains; improving the quality of repairs and maintenance. It is noted that the sources of increased complexity of managing the passenger car fleet are the constantly increasing complexity of business processes automated at the linear enterprise, which conflicts with the existing regulatory and technological base, as well as increasing requirements for the speed and accuracy of execution of all operations with cars. It is also indicated that automatic monitoring of the input sequence of source documents and its information interconnection should be created in the developed system and a system of automated control and prevention of conscious violations performed by users should be developed in order to improve the performance of their own work. The system should control the user's actions as much as possible and check the information entered by the user for compliance with regulatory requirements.
