Kolomiiets S. Improving the environmental safety of motor transport enterprises

Qualification scientific paper, manuscript. The thesis for the degree of Candidate of Sciences in Technology, specialty 21.06.01 – Environmental safety. National Aviation University, Kyiv, 2019. The thesis solves actual scientific and applied task to improve environmental safety of motor transport enterprises by minimizing energy consumption and environmental pollution by harmful emission and waste during technological processes of restoring the working capacity of vehicles. The methodology for assessing the level of environmental safety of motor transport enterprises based on the mathematical model for determining fuel and resource consumption, harmful emission and waste has been developed. It takes into account the type of vehicles, the peculiarities of the vehicle motion modes in separate technological cycles, the characteristics of technological operations, the periodicity of the main technological influences in vehicle life cycle. A system of criteria for assessing the environmental safety of motor transport enterprises has been developed. It consists of ten separate criteria for estimating stationary and mobile sources of harmful influence of the enterprise. They are based on the analysis of essential environmental aspects of separate technological processes of vehicle maintenance and repair. They are grouped according to resource use, emission and waste, and integral criteria which forms a target function determining the level of environmental safety of motor transport enterprises. A program module for monitoring the parameters of vehicle technical condition and separate indicators of vehicle environmental safety in the technological processes of motor transport enterprises has been developed. It enables to predict the indicators of environmental safety of separate vehicles in the life cycle and motor transport enterprises in general. The influence of technological processes at motor transport enterprise on fuel and resource consumption, emission and waste in the vehicle life cycle has been investigated. Recommendations for improving the environmental safety of the enterprise have been developed.
