Abstract. In this paper the expert ranking method has been applied
in the process of forming the operator's reliability model in the control
centres of the coal mines in Serbia. The expert group determined the important
reliability/risk factors and estimated their influence on the operator's
reliability. The ranking process and determination of concordance coefficient
has confirmed the uniformity of expert group opinions. Weight coefficients
of reliability factors have been determined using the iterative procedure,
which includes different competencies of experts. On the basis of these
results the reliability model of operator-dispatcher has been defined.

FORMIRANJE MODELA POUZDANOSTI
U CILJU PROCENE RIZIKA OPERATORSKE DELATNOSTI
U radu je prikazan ekspertni metod rangiranja i njegova primena za formiranje
modela pouzdanosti operatora-dispečera u centrima upravljanja u rudnicima
uglja. Ekspertna grupa je definisala bitne faktore pouzdanosti, odnosno
rizika, i ocenila njihov uticaj na pouzdanost operatora. Postupkom rangiranja
i određivanjem koeficijenta konkordacije potvrđena je saglasnost mišljenja
eksperata. Iteracionim postupkom koji uključuje različitu kompetentnost
eksperata, određeni su težinski koeficijenti faktora pouzdanosti. Na osnovu
toga formiran je model pouzdanosti operatora-dispečera.
