Generally, the scores of sunshine amount, distance, shaded area and shaded area change speed are positively correlated with the size of sunshine amount, distance, shaded area and shaded area change speed.

In another exemplary embodiment, the weights of the sunlight amount, distance, shaded area, and shaded area change speed can be different, for example, the weights of the sunlight amount, distance, shaded area, and shaded area change speed can be set in a descending order.
