Abstract: The paper presents a method for assessing the operational efficiency of transport telematics systems. In order to obtain a relatively general assessment of the operation of transport telematics systems, the analysis of a multi-state operation process was adopted as the assessment method. Subsequently, a model of the telematics system operation process was developed. A problem of fundamental importance in efficiency research is the determination of partial efficiency measures. Using the characteristics of the operation process, a model of the operational efficiency of the telematics system was developed, and measures for its assessment were presented.1. INTRODUCTION
The efficiency of a telematics system can only be assessed if the answer to the question – can the system perform the tasks imposed on it? – is positive. A positive answer indicates the system’s suitability for performing tasks, taking into account the ability to provide telematics services through technical equipment, personnel qualifications, proper organization of the usage and maintenance process, etc. [9].
Regarding technical equipment, it is necessary to take into account its failures, the complexity of maintenance, repairs, and renewal possibilities. An important factor influencing efficiency is the reliability of technical equipment, but one must also take into account the possibility of reduced work quality resulting from poorer equipment reliability. During the operation period of technical equipment, the following periods can be distinguished:
− fitness for work and waiting for the realization of telematics services;
− fitness for work and realization of telematics services;
− planned maintenance, inspections, repairs;
− emergency repairs.
The fundamental methodological issue in assessing the operational efficiency of a telematics system is the construction of a mathematical model that is adequate to reality, covering the largest possible number of combinations of various factors, yet allowing in each specific case to include only those factors that correspond to the research task. As a method for assessing operational efficiency, in accordance with considerations in [2], [10], among others, the analysis of the stochastic process of telematics system operation was adopted. This leads to the construction of an operation process model and the determination of selected characteristics of this process, which in themselves can constitute partial assessment measures or can be elements of more general dependencies for assessing operational efficiency.
