The main subject of this paper is the analysis of possibility of fuzzy logic elements implementation in the field of systems operation evaluation. The analysis considers complex systems exploitation process. The process is evaluated on a base of the system features values. The changes of system features values describe the quality of system operators’ activity, technical objects and surrounding environment influence. The quality of system operation is the function of exploitation process safety, efficiency and reliability. The evaluation and assurance of required quality of system operation is the main factor in exploitation process. On the base of created complex method of systems operation evaluation the fuzzy model was built. The sharp values of system features are the input parameters of the model. In this model the range of analyzed system features was partitioned by fuzzy digits. In the paper the fuzzy representation of system features was presented. The multidimensional and model vector of system operation quality is also described. The highest system operation quality presents the case when these spaces have not empty intersection set. The lower quality is when spaces are tangential. The lowest quality is when the spaces have empty intersection set. The pattern of systems operation quality and their current evaluation in the moment t is calculated on the base of the points in n-dimensional space. The position of the spaces is described by the rages of systems features values. The features are the functions of the time. To model all these situations in the paper the evaluation of system operation quality is interpreted as multi objective analysis problem soled by fuzzy sets theory implementation.
