Prediction of the learning curve in roof insulation

Mathematical learning curve models can be used in construction to predict the time or cost required to perform a repetitive activity. In this study, we evaluated mathematical models for different learning curves for flat roof insulation reconstruction work. Our evaluation was based on a survey conducted in the spring of 2009 in Budapest. The survey was conducted to determine the total construction time required for bound parts of flat roofs and for the related activities, such as demolition or laying heat insulation boards. Several mathematical models were identified, and each was used for prediction. The objective of this study was to determine which of the models considered was the most accurate for the prediction of future performance. The models were compared with each other and with the measured data.
