Multistage Stochastic Programming using EMP extension

Hi, I am having some issues with stochastic programming problem using EMP extension. Block diagram of my model looks like this; image.png The max Generation capacity of Generator is 1500 KW, the whole year's site demand probability distribution is given. At each demand level, there is a probability ...

2 Random Variables in stochastic programming using EMP

Hi, I am wondering if I am using random variables in Stochastic Programming correctly using EMP. The code in my model looks like this; It doesn't give an error but also doesn't give a proper solution and repeats the values in Scenarios. My question is if I am correctly defining random variables (X a...

JAMS Pre Processing Failed - Solver Error

Hi, I am experiencing a solver problem at the execution of GAMS file. I am trying to implement a two stage problem using stochastic programming similar to News Vendor Problem using emf (Extended Mathematical programming) solver. It comes up as ***status: Normal Completion without any Erros but also ...
