Robust fuzzy decision support system for manual room ventilations in preventive conservation

In the area of preventive conservation special climate requirements are present. Especially fluctuations in climate values should be reduced in order to avoid damages of the sensitive materials of cultural heritage. In several applications no modern ventilation systems are present, such that the only ventilation option is the opening of windows and doors by human. Therefore serious climate fluctuations occur, if the ventilation strategy is not adapted to the climate situation. To avoid this situation, a monitoring and decision support system has to be developed. In this contribution we describe a fuzzy concept for such a system, analyze the influence of the fuzzy approach and explain the practical realization in a demonstrator application.
