Dear Samir,
You could use something like the following:
Tsouf = 20*LT(Text,16) + (….)*GE(Text,16)*LT(Text,32)
+ 18*GT(Text,32)
With (…) = Input2-(Input3/(0.34*MAX(Input4,0.0001))
The LT, GE and GT are boolean equations (less than,
greater or equal than, greater than) resulting in a factor of 1 if the
condition is satisfied and 0 if not. So for eqample Text = 18,5 would give:
Tsouf = 20*1 + (…)*0 + 18*0 = 20
Good luck
Stefan de Kool

equation
Hello,
I try to model this schedule :
If Text<16 Tsouff = 20
If 16<Text<32
Tsouff = Input2-(Input3/(0.34*MAX(Input4,0.0001))
If Text>32
Tsouff = 18
And I don’t know how integrate these conditions with “equation”.
Best Regards
