Transport device operator stress features analysis

Woźniak D. , Rumian S. , Szpytko J.

tom Vol. 18, No. 4

577-586

The paper is focusing on known publications review concerning the transport device operator stress features and identification possible and their influence at man decision making process. The paper composition include: stress phenomenon analysis, human features and stress interaction analysis, human availability models including stress factors, and stress analysis tools analysis. Stress has been recognized as a major influential factor to affect the operator's health, safety, and productivity. Stress is subjective and express man reaction from external to potential reactions. The operator stress is often expressed as quality of life indicators related to satisfaction with a given domain of functioning and have influence at the human operation potential (health). Studies on the role of the state of mental and physiological functions are an important part of the theory of operators working reliability and a cause-and-effect relationship between the functional state and their availability. The review on known selected publications concerning the transport device operator stress features and others, including own research, helps to identify possible stressors acting at man and their influence at decision making process. The measure possible stress parameters: physiological, subjective and behavioural types have also been discussed. The transport devices' operator fatigue remains to be one of the important factors that contribute to possible accidents accompanying transportation processes. The problem of availability and reliability of human operators activities are today more practically oriented crucial and a branch of applied psycho-physiological research.

W artykule dokonano analizy wpływu materialnego środowiska pracy, ze szczególnym uwzględnieniem drgań i hałasu na sprawność operatora środków transportu. Badania ankietowo-eksperckie przeprowadzone na grupie maszynistów oraz kierowców przewożących towary niebezpieczne pozwoliły wytypować cechy wpływające na uciążliwość pracy. Cechy te wykorzystano w budowie modelu działań maszynisty oraz modelu wpływu czynnika ludzkiego na prawdopodobieństwo wystąpienia wypadku drogowego. W modelowaniu wykorzystano heurystyczne struktury rozmyte (struktury Mamdaniego i Takagi-Sugeno-Kanga). Modele implementowano numerycznie w środowisku Matlab_Simulink i wykorzystano do symulacji wpływu wybranych cech na sprawność operatorów.

The article analyses the impact of the material environment, with particular regard to vibration and noise on the efficiency of the transport means operator. The questionnaire/expert-based surveys carried out on a group of locomotive drivers and drivers carrying dangerous goods allowed the prediction of characteristics that affect the hardship work. These features were used in the construction of the driver's action model and the model of the impact of the human factor on the probability of an accident. The modeling used a heuristic fuzzy structure (structure of Mamdani and Takagi-Sugeno-Kanga), numerical models was implemented in an environment Matlab_Simulink, and used to simulate the impact of selected features on the efficiency of operators.
