OPTIMIZATION OF ENTERPRISES' OPERATION IN PERFORMING PASSENGER TRANSPORTATION BY QUALITY CRITERIA

Abstract

Economic, technical and operational performance of passenger road transport is a crucial aspect in the planning of transport processes. The performance of passenger road transport for public transportation is primarily related to the quality of passenger services. The quality of transport services is determined by a set of properties and characteristics that must meet the needs of consumers: a clear schedule of vehicle stock; speed of connection, level of tariffs; comfort and reliability of buses, cabin filling, especially during rush hour and some others. The most important factors for transport operators are the cost of transport services. Improper organization of passenger transport leads to unjustified costs. The efficiency of transport depends on properly defined indicators – organizational, technical (type, quantitative composition, passenger capacity of vehicle stock etc.), operational (speed, intervals, trip time on the route etc.), as well as qualifications and responsibilities of drivers, along with other management measures. Therefore, research related to improving the efficiency of vehicle operation by reducing costs is appropriate and relevant. The article presents the results of research on the planning of the transport process in the performance of road transport for public transportation on urban and suburban routes. It is presented an algorithm which optimizes the quantitative composition of vehicles on the route, passenger capacity, traffic intervals depending on the capacity of passenger load, and also allows to calculate technical and economic indicators. The results of the survey of public transport passengers against the criteria of services' quality and their priority are presented. Thus, according to the results of research, the main purpose of which is to solve a multi-criteria problem of minimizing fixed and variable costs in the performance of passenger road transport, is the optimization of interconnection between quality indicators of vehicle stock and planning, organizational and production principles.
