Today I was running my energy model and I faced this weird infeasibility in the listing file:
balance_activities(Houses - Residential Terrace,2050) ..
+ 1 * tech_use(Res03_01,2050) + 1 * tech_use(Res03_02,2050) + 1 * tech_use(Res03_03,2050) + 1 * tech_use(Res03_04,2050)
+ 1 * tech_use(Res03_05,2050) >= 4060 ; ****
name lower upper
tech_use(Res03_01,2050) 0 0
tech_use(Res03_02,2050) 0 0
tech_use(Res03_03,2050) 0 0
tech_use(Res03_04,2050) 0 0
tech_use(Res03_05,2050) 0 4060.000
It seems the upper bound of
tech_use(Res03_05,2050) is respecting the mentioned constraint as 4060.000 is larger than 4060. Do you have any idea why AIMMS arises this ifeasibility?
Thank you in advance.

Note: the option 'Constraint listing feasibility tolerance’ determines the feasibility tolerance used by the constraint listing.
