Abstract

Evaluation in its non-formal sense is not a new thing. Man has almost always used evalulation to gain information about his actions to improve his affairs. Nowadays, evaluation in the form of the qestionnaire, is viewed as a scientific approach which, aided by the use of statistical techniques, has proven useful in practice.
Questionnaires comprise different questions, each one providing a part of the required information. As a rule, in designing the questions of a questionnaire, depending on the aim of the research, methods are devised to measure the size of the reliability and validity of the instrument in which equal weight is given to all of the questions, thus attaching equal importance to them. Since some of the questions provide more signifcant pieces of information, it seems that determining an appropriate weight for each question will reflect the results of the questionnaire in a more realistic way.
The aim of this study was to provide a suitable method for correct valuation of the items on the questionnaire of the academic members general evaluation. To achieve this aim, first the researcher decided to collect the experts points of view by studying the relevant literature and by using group Analytic-Hierarchy-Process (AHP) and mathemtical modal model of operation research (OR), the new weight for each item of the questionnaire was determined.
The result of the application of the new coefficients to the questionnaire, administered to 30 members of academic staff, all randomly selected, showed a significant difference in comparison to the former that of questionnaire.
