One of critical tasks of cadastre system maintaining is the input of changes into its database. Managers of information centres often complain they have no adequate tools for the assessment of work of cadastre system operators. In the paper a fuzzy model is proposed which goal is to provide a useful tool for management of an information center. The architecture of the fuzzy system comprises five main modules of operators’ work statistics, fuzzification, inference, defuzzification and visualization. For each input criterion i.e. productivity (P), complexity (C), time (T) and quality (Q) as well as for output assessment triangle and trapezoid membership functions have been defined. The statistics module provides initial parameters of the model and values of input criteria. The model based on change records saved in cadastre database produces the assessments of operators’ work for defined periods of time automatically.
