Hi Jaromil, Many thanks for the responses. Please if you could help in understanding the reason why does it makes the values of all beta equal to zero. Kind regards, Saad

Hi! Somehow I have removed the errors and my program is working and optimizing but it is making one of my variable equal to zero for all values. (Screenshot is attached ) What could be the possible...

Hi Jaromil, I tried to formulate the first constraint like this: for t in T: \begin{equation} model.addGenConstPWL(y_t, r, [0, 50, 50, 100, 100, 150],[0, 0, 0.05, 0.05, 0.1, 0.1]) \end{equati...

Hi Jaromil, Yes, $p_t$ is a constant and it's working. But there is another term added to the objective function which contains another variable. So, in that case shall I state separate objective f...

Hi Jaromil, Many thanks for the answer. It surely helps a lot in understanding how to formulate the piecewise objective function but I still have one confusion. What does this $y$ value indicates a...

Piecewise Objective function and Piecewise constraints
回答済みMy objective function is: \[\begin{equation}\min \sum_{t=1}^T p_{t} \cdot (1+r) \cdot y_{t} \end{equation}\] where \(p\) is the price, \(y\) is the quantity (decision variable) and \(r\) is the pri...

Hi Matthias, Thanks for the answer. Could you please provide a clue as to how we could formulate piecewise objective function for this problem. I went through the examples mentioned but can't rel...

Using the values of variable in the objective function before optimizing
回答済みHi! I am facing a problem to multiply a term in objective function. My objective function is : \[\begin{equation}\min \sum_{t=1}^T p_{t} * (1+r) * y_{t} \end{equation}\] where \(p\) is the price, ...

Hi Jaromil, these $b$ and $d$ aren't known a priori and are in the form of a list.
