• Resumen

  • The phenomenon of learning was first expressed mathematically in 1936 by T. P. Wright. He observed in the aircraft industry that certain costs per unit tend to decrease in a predictable pattern as the workers become more familiar with the work.

    Studies have shown that the change in cost associated with a change in productivity has, in many situations, a characteristic curve that can be estimated with reasonable accuracy. This is called the learning curve or experience curve. The underlying phenomenon is that skill and productivity in performing tasks improve with experience and practice and there are a number of different ways of plotting this relationship that facilitate mathematical analysis.

    A first attempt to quantify the effect of repetition in building was made in an enquiry undertaken between 1960 and 1962 by the United Nations' Economic Commission for Europe. This article tries to spread the principle of learning curves and their application in the construction industry to improve productivity.
