Hello, I'm using version 23.5.1 When I start the optimisation, the log file (.lst) reports "Cplex MIP uses 1 of 8 parallel threads. Change default with option THREADS" When I incorporate the option threads=8 I get the error 250 "Unknown option" and a list of valid options (ex: in...

Hi,

I´m using the version 23.5.1 and for some reason the "OPTION Threads = 8" is not working.
I get the error 250 "Unknown option"

Does anyone knows how can I solve this problem ?

Thanks

I’m trying to optimize a furnace (melting iron) weekly production scheduling. I have 168 hours with 168 hourly prices, and I need to choose the best daily hours to schedule my melting process The melting process is 1 hour loading the furnace and 3-hour melting. 4 hour melting block in total. Loading...

Hi, I have a annual model for energy/price optimisation with an hourly granularity (8760 hours) The hydro unit can deliver 2 kind of services with different prices. These services are mutual exclusive, it can not deliver the 2 services at the same time. The difficult part is that one of the services...

Hi all, I'm currently have a model that is running on a loop to test several configurations on different scalar/parameters. Different set of configurations = different results that I want to store and analyse later On a single run, I can export a csv file with detail results from GAMS. When I try to...

Hi, In the "A GAMS Tutorial by Richard E. Rosenthal" (https://www.gams.com/latest/docs/UG_Tutorial.html), I'm trying to run the model several times in a sequential way in order to see the influence of changing same SCALAR/PARAMETERS in each model run Problem 1 What I want to do is to run t...

Hi, Hi have a battery operating in several markets and I want to ensure that the model don't charge ( charge(i) ) and discharge ( discharge(i) ) at the same time. I use the solution charge(i) * discharge(i) = 0. The problem is this is a NLP model. How can I change this, in order to transform this mu...

Thanks a lot Steve !!!
