| description | The necessity to improve assessment of aviation security screeners’ competence has been analyzed. Computer based training systems have been widely used in the process of screeners’ training and evaluating the results of training. The main advantage of similar systems application is the possibility of adaptation to the individual screeners’ requirements by changing the level of training task complexity. The efficiency of applying these systems is proved by foreign researches. To assess the results of screeners’ activity the dangerous image projection data is also used. The analysis of modern approaches to assess the screeners’ activity efficiency showed that they do not completely take into account x-ray image complexity factors affecting the results of screeners’ activity monitoring. There have been presented and tested A. Birnbaum two-parameter model, which is used to assess the screeners’ proficiency competence by means of testing. According to International Civil Aviation Organization recommendations the x-ray image data base has been formed; it includes four blocks of prohibited items. Within the suggested model the probability of detecting prohibited items by aviation security screeners is considered as functions of such parameters as the difference between level of qualification and level of x-ray images complexity, and also between the aviation security screeners’ structure of their professional knowledge. The solution of the task to search A. Birnbaum model parameters values by using maximum likelihood method have been offered. Within the model the qualification level characteristic functions, which describe multi-complexity level of x-ray image interpretation competency of the aviation security screener, were generated and explored. Complex criterion to assess the level of the aviation security screener qualification is offered and tested. The suggested criterion allows to evaluate aviation security screeners’ competency taking into account not only the average level of qualification, but its possible variance. The suggested criterion may be used while selecting and certificating the screeners when the requirement to detect at least 95% prohibited items is applied. |
