The dissertation work, which is a completed scientific study, presents the solution to the relevant scientific and applied task of increasing the efficiency of occupational safety management in the operation and maintenance of special types of transport by identifying the relationships between the functions describing the transportation process of cargo transportation by special types of transport and the criteria determining the conditions for performing the production task, allowing to determine the level of professional risk for the driver.
Based on the analysis conducted, it is shown that the safety of operating a quarry dump truck depends on the main key elements forming the system: "driver-vehicle-road" (hereinafter - the "DVR" system). Failure of any element of the DVR system increases the likelihood of its deviation from the normal-functional state and, most importantly, contributes to an increased risk of accidents. Transportation technology experts highlight the driver as the most important element of the DVR system, requiring a proper level of control over their psychophysiological state during the performance of professional functions to reduce errors while driving. Since continuous information exchange occurs within the DVR system: from the technical condition of the vehicle and road conditions to the driver's own feelings, who provides commands for control and receives information about the results of their actions through feedback channels for corrective actions according to changes in environmental conditions, there is a need for improved management of occupational safety in the operation and maintenance of special types of transport. To address this issue, it is proposed to apply the Functional Resonance Analysis
Method (FRAM), which is based on the study of the functions of the transportation process within freight truck transportation, considering six different aspects: input data, time, control, resources, preconditions, and output. In this regard, the assessment of the professional risk of an undesirable situation arising from the simultaneous action of several factors during cargo transportation is proposed to be carried out based on a phenomenological model, which aims not to establish any rigid laws of interaction between factors and events, but only to generalize their cumulative impact on the studied process. This allowed determining the relationship through FRAM analysis between the variability and timeliness of the transportation process, which is described by five main functions: preparation of cargo transportation, dispatching of cargo vehicles, loading, transportation, and unloading of cargo at the destination with a level of professional risk, considering six main factors: driver experience, level of control, transportation time, route complexity, and availability of driver support from management. Thus, a model of occupational safety management system in the operation and maintenance of special types of transport based on the study of the functions of the cargo transportation process, considering six different aspects: input data, time, control, resources, preconditions, and output, was developed, allowing to assess the professional risk of an undesirable situation arising from the simultaneous action of several factors during cargo transportation. Based on the constructed model, the possibility of predicting the execution of cargo transportation at the proper level was demonstrated by calculating quantitative assessments of task execution reliability at the proper level and the risk of schedule disruption for two scenarios: the first when all safety requirements and conditions are met, and the second when there are a certain number of violations of the specified requirements and conditions, which allowed identifying a nearly twofold decrease in professional risk. Therefore, the implementation of enhanced control over the execution of the transportation task will lead to increased reliability and a decrease in the determined risk magnitude.
The calculations of various scenarios allowed to establish that the preparation and transportation of cargo are the most injury-prone functions of the cargo transportation process in mining enterprises, which are associated with their significant changeability and variability
of technological operations dictated by the number of production tasks for sending cargo and high demands of customers for the quality of transportation services. Moreover, during cargo transportation in mining enterprises, the most influential factor is the driver's psychological state due to loss of attention associated with distracting actions or driver fatigue during cargo truck control; failure of cargo truck technical systems due to design flaws, inadequate technical maintenance, or transportation vehicle operation; road conditions related to the formation of road surface, yields, turns, inclines, power lines, and other infrastructure objects that may restr
