When I use Lingo 12 to solve a mixed integer linear model, the "infeasibility" in the Lingo 12 solver status shows a pretty small number (10^-15), which you can see in the attached figure. If "infeasibility" is not 0, does it mean that the model is not feasible or the solution is not feasible? Thank you very much for your kind explanation.

At first, you get the global optimal solution, not local optimal.
You must understand the meaning of zero. Usually, most software decides Abs(x)
