How to use variable in functions in Pyomo
0
I define a function in pyomo as below:
def func(model,i):
alpha = (model.a[i]+model.b[i])/2
X = model.W1[i] if i in model.Vc3 else model.W2[i]
return fuzz.trimf(np.array([X]), [model.a[i], alpha, model.b[i]])
model.func = Expression(model.VcT, rule = func)
def Cons003(model,i):
return model.Mu[i] - model.func(model,i) <= M * (1- model.P[i])
model.Cons003 = Constraint(model.VcT , rule = Cons003)
def Cons004(model,i):
return model.Mu[i] - model.func(model,i) >= M * (1- model.P[i])
model.Cons004 = Constraint(model.VcT , rule = Cons004)
When i execute the code i get error massage as:
No value for uninitialized NumericValue object
model.W1[i] and model.W2[i] are problems variables.
How can i solve this issue?
you can find model and data file in here.
