Table 9 Fitting results for the expected construction period and probability of completion.
From: Schedule risk model of water intake tunnel construction considering mood factors and its application
Fitting method | Expected construction period\(T\)(d) | \({R}^{2}\) |
|---|---|---|
Linear fitting (\(\alpha\)and\(\beta\)are both first power) | \(T=388+0.472 \alpha -0.1744\beta\) | 0.9848 |
Completion probability\(P\)(%) | ||
Linear fitting (\(\alpha\)and\(\beta\)are both first power) | \(P=59.72-0.6983\alpha +0.4294\beta\) | 0.9361 |
Nonlinear fitting (\(\alpha\)is first power and\(\beta\)is second power) | \(P=47.56-0.5622\alpha +0.9939\beta -0.002722\alpha \cdot \beta -0.004283{\beta }^{2}\) | 0.9714 |
Nonlinear fitting (\(\alpha\)is second power and\(\beta\)is first power) | \(P=55.2-0.7447\alpha -0.5655\beta -0.002722\alpha \cdot \beta +0.001825{\alpha }^{2}\) | 0.9531 |
Nonlinear fitting (\(\alpha\)and\(\beta\)are both second power) | \(P=49.84-0.7447\alpha +0.9939\beta +0.001825{\alpha }^{2}-0.002722\alpha \cdot \beta -0.004283{\beta }^{2}\) | 0.9754 |
