Non-Parametric Procedures in Evaluation of Collective Professional Skills of a Human-Operators Shift

Abstract

Abstract The paper is devoted to a methodology oriented to eliciting professional skills of a shift of human-operators of a technological plant by applying system identification techniques. Within the frameworks, the aim is to derive an input/output model that might reflect the actual level of collective professional competences and skills. Deriving the required input/output model is based on applying such a kind of the “proxy”, that is indirect, variables as the time. Namely, there is applied the time that is needed to the shift of human-operators to make a decision on the plant process behavior using the information provided by information sources distributed over an information-and-control board, such as, say, group view displays (GVD) or, generically, within a total control room. In turn, these times are proposed to be fixed by use of eye trackers. Obtained in such a manner and calculated by use of data of observation of actual algorithm of collective performance of an experienced human-operator shift, the model characteristics represent a tool for evaluation of human-operators shift experience.
