Note. The higher the R2, the better the function model. In the W19 model fitting, the fitting of the quadratic curve is the best, and the quadratic curve is selected. The bed number of W19 is C5, and the bed utilization rate is BOR5 (C5). According to the estimated value of the parameter, BOR5(C5)=0.911+0.012C5 − 0.0003054C52.
