Study on Labour Productivity by Learning Curve Effect

Learning curve theory is based on the phenomenon that productivity improves through the repetitive tasks. In construction planning, the evolution of repetitive scheduling methods led to the introduction of learning concept. It is a common knowledge that performing the same activity repeatedly, and in the same condition takes less time as the activity is repeated. This phenomenon is clear in many construction activities and is known as learning experience or learning effect. A straight line model can be used as a base model of learning curve for this project. It contributes a development of algorithm for predicting construction activity time based on learning curve theory. It also identifies the factors that affect the labor productivity by conducting a questionnaire survey.
