Estimation of Production rates for Formwork Installation using Fuzzy Expert Systems

Expert Systems have been used to solve complex problems efficiently if the
information available is in descriptive form rather than numbers. The study has aimed to use
Fuzzy expert systems to estimate the labor production rates. Production rate values of formwork
installation of beam have been measured from the project sites and factors influencing the
production rates have been recorded on scale in descriptive form. Fuzzy expert system
developed in this study has been compared with the previous Fuzzy expert systems used for
estimating production rates. Mean Square Error of the previous and new models has been
calculated and shows that proposed model gives high linguistic and numerical accuracies.
Hence, the Fuzzy expert system developed in this study can be used reliably for estimating labor
productivity by the construction Industry.
