S = PW

E(PW)

2

S = NA + PW

a*E(PW)*E(NA),where a is adjustable parameter, its value range is from 1/2 to 1

3

S = NA + NA + PW

E(PW)*E(NA)*E(NA)

4

S = DA + PW

(1 + E(DA))*E(PW), E(DA) < 0 E(PW) + (1-E(PW))*E(DA),E(DA) > 0 & E(PW) > =0 E(PW) + (-1-E(PW))*E(DA),E(DA) > 0 & E(PW) < 0

5

S = DA + DA + PW

E(PW) + (1-E(PW))*(E(DA1) + (1-E(PW)-(1-E(PW))*E(DA1))*E(DA2)

6

S = NA + DA + PW

E(PW) + (1-E(PW))*(E(DA)-0.2))

7

S = DA + NA + PW

E(PW)*E(NA) + (-1-E(PW)*E(NA)*E(DA)
