Abstract	Time-cost optimization problem is one of the most important aspects of construction project planning and control. And the relationship between direct cost and activity duration is the base of project planning and control. Nowadays, when construction planners made an optimization of time-cost, they assumed the rate of direct cost is linear in order to calculate it simply. But in fact the direct cost of the project in function is non-linear. In order to obtain the relationship between direct cost and activity duration, this paper developed a universal non-linear function of the direct cost based on support vector machine (SVM). We can get the non-linear function of the direct cost through determined the coefficients of the function with SVM. This non-linear function of direct cost can describe the relationship between direct cost and duration more precise. And it can help construction planners to control project cost. After simulation of project, the validity and practicality of the method have been verified.
