METHODOLOGY FOR EVALUATION OF SUBJECTIVE SATISFACTION OF OPERATORS BY USER INTERFACE OF THE SOFTWARE OF ACS

A technique for assessing the subjective satisfaction of operators with the user interface of the software for automated control systems (ACS) is proposed. A model of indicators affecting operator satisfaction is presented. The model is presented both graphically and using tuples. All stages of work related to the formation of a representative group for testing, preparation and testing, as well as processing of the results are considered in detail. The dependences of the average group error and the proportion of problems found on the number of experts are analyzed and recommendations are given on the formation of a representative sample, interviewing operators and conducting usability testing. Formulas for processing research results and calculating satisfaction ratings are presented. The proposed model and methodology represent a methodological basis for creating a system of information support for developers of ACS, ACSTP, APCS and complexes for various purposes.
