Prediction model of the useful life of a heritage building from fuzzy logic

We seek a procedure to identify and assess the factors that affect the vulnerability and risks affecting the building and validate a model to calculate service life. We would thus have a prediction method that would be very useful in the process of maintenance and conservation of the built heritage. The problem is that in analyzing the various methods currently used to predict events in the field of heritage conservation, we find that such methods are at the threshold of uncertainty. For this reason, we have chosen to work with the theory of fuzzy sets (fuzzy set), as most appropriate tool. When generated prediction model based mathematics, what we have called FBSL (Fuzzy building service life) and provide satisfactory results, when predicting the building service life.
