Method for initial assessment of unit costs of public city transport means operation

Abstract

The study deals with the problems connected with modeling and simulation of technical objects operation processes carried out within a certain class of complex technical systems. The analyzed system is a city bus transport system. The study presents a method for assessment of unit costs involved in a technical object’s being in selected operational states. One of the subsets of data to be used for modeling the process of a technical object operational state changes, includes data concerning the costs borne by the system when the object is in the analyzed operational states. In order to determine this data, it is often necessary to modify the system of costs registration used in a given operation system. Since it is a very expensive and log process, a method of initial assessment of indispensable data has been proposed, on the basis of a costs registration method and simulation of the operation process. The study also includes basic assumptions of the operation process model, being an important element of the developed method. The assumptions of the operation model have been formulated on the basis of identification of a real operation system of city bus transport system and experimental tests carried out in system.

Impact of the epidemiological situation in Poland in 2020 on the public transport system

“…One of the basic functions of computer programs supporting maintenance services is the registration of data on individual vehicle states. After implementing such systems, it is possible to automatically generate periodic reports containing various damage indicators, including indicators defined by software users [10][11][12][13].…”

Method of modelling operation and maintenance processes in public transport systems using a certain class of stochastic processes

“…Operation efficiency of city transport systems and operated by them transport means can be analyzed in terms of economy and technology [1,[7][8][9].…”

“…When analyzing operating costs of such systems it is necessary to take into consideration different cost categories including the costs involved in operation of subsystems whose task is to provide transport means with usability and those which deal with maintenance of the vehicles to keep them ready for use [2,[7][8]. Bus transport system operations involve many different costs including those involved in application of lubrication oils.…”

Analysis of changes in the value of selected lubricant characteristics during use

“…Engine oils make up the costs involved in transport means operation [2][3]. In the case of large lubricating systems and short time between the oil changes, the costs are of particular significance.…”
