Advanced and Novel Methodology for Scientific Support on Decision-Making for Stone Cleaning

The configuration of assessment criteria, methodology compilation, and the strategic planning of cleaning interventions applied on architectural surfaces of monuments are discussed in this chapter. This is accomplished by the use of an integrated decision-making system to assess cleaning interventions on stone architectural surfaces that present the characteristic decay pattern of black crusts. The system was developed by the incorporation of a fuzzy logic model into GIS enabling strategic planning through constant response in relation to the cleaning performance in a pointed spatial entity and environmental conditions. The developed, advanced, and novel methodology for scientific support on stone cleaning was demonstrated in practice on marble surfaces of a historic building in Athens, Greece.
