Широкое распространение при подготовке и оценке качества ее результатов операторов получили автоматизированные обучающие системы. Основным преимуществом применения подобных систем являются возможность приспособления к индивидуальным потребностям оператора путем изменения уровня сложности учебного материала. Эффективность применения данных систем подтверждается на основании зарубежных исследований. Для оценки результатов деятельности операторов также применяется технология проецирования опасных предметов. Анализ существующих подходов к оценке эффективности деятельности операторов показал, что они не в полной мере учитывают влияние факторов сложности рентгеновских изображений, на результаты контроля деятельности операторов. Представлены результаты апробации двухпараметрической модели А. Бирнбаума, которая служит для оценки профессиональной подготовленности операторов досмотровой техники посредством тестового контроля. В соответствии с рекомендациями Международной организации гражданской авиации был сформирован банк тестовых рентгеновских изображений, включающий в качестве четыре блока опасных предметов. Согласно модели вероятность обнаружения запрещенных предметов операторами рассматривается как функция от таких параметров, как разности уровня подготовки и уровня сложности изображений, а также меры структурированности знаний. Представлено решение задачи поиска значений параметров модели А. Бирнбаума методом наибольшего правдоподобия. В рамках модели были построены и исследованы характеристические функции уровня подготовленности испытуемых, описывающих их способности по интерпретации рентгеновских изображений различной трудности. Предложен и апробирован критерий оценки уровня подготовленности операторов. Критерий позволяет учитывать не только средний уровень подготовленности оператора, но и возможную его дисперсию. Предложенный критерий может применяться при отборе и сертификации операторов в случае установления к ним требования почти безусловного решения задачи поиска запрещенных предметов.</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>авиационная безопасность</kwd><kwd>оператор досмотровой техники</kwd><kwd>оценка профессиональной подготовленности</kwd><kwd>характеристическая функция</kwd><kwd>критерий подготовленности</kwd><kwd>адаптивный подход</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aviation security</kwd><kwd>aviation security screener</kwd><kwd>assessment of proficiency</kwd><kwd>characteristic function</kwd><kwd>criterion of competence</kwd><kwd>adaptive approach</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Schwaninger A., Hardmeier D., Hofer F.
