No, you can only run one loaded scenario per time, but, you can develop a procedure that loads a scenario, delegates it, and save in a prefolder, until all scenarios are run. After that you can load all and compare them at once.

Thanks a lot for this reply! Can you tell me what should I refer to to realize this? Like which part of the handbook or language reference should I refer to? Or is there any article realising this?

You do not have access to AIMMS PRO correct? So, to do this locally, it is a matter of:

• Create a set of all scenarios you want to run.
• Do a for for these scenarios.

• Check if folder exists (/batchRun)
• LoadCase on the for
• solve mp
• SaveCase on (/batchRun)

Or,

• Check if folder exists (/batchRun)
• LoadCase
• Change the parameter dynamically during this procedure
• solve mp
• SaveCase on (/batchRun)

After, to compare all cases, check this article: https://documentation.aimms.com/user-guide/data-management/case-management/managing-multiple-case-selections.html

I really appreciate this! I will try to do it with this instruction!
