A case study of S-curve regression method to project control of construction management via T-S fuzzy model

In the contractual business, construction firms are generally more concerned with short-term financial strategies than the long-term ones. Working capital management is the central issue of all short-term financial concerns. Thus, it's urgent to study the cash portion of working capital management to rationalize the amount of cash and current assets possessed in certain time. The S-curve is quite suitable to represent the relationship between project duration and complete progress in practical usage of construction management. Based on the technique of Takagi-Sugeno (T-S) fuzzy model, the fuzzy regression model is constructed for curve fitting problems. According to the cash flow of the example projects, this paper develops a practical S-curve regression model demonstrated and given tentative conclusions.
