JAMS Pre Processing Failed - Solver Error
Posted: Tue Jul 10, 2018 1:11 am
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 having these two messages in .lst file
*** EMP syntax error: key expected: is neither a variable nor an equation: randvar (item 1 on line 2)
***
*** JAMS Pre processing failed
***
I have tried changing syntax but the issue remains and though its a Normal completion but it doesn't solve the uncertainity issue in the problem.
Can anyone please elaborate what could be the issue. I have attached my GAMS file.
•Capacity of 4th generator needs to be a decision variable.
•Capacity of 4th generator is stage1, as is the objective function.
•Cost of 5th generator (system buy price) is a random variable.
