In Operations Research, infeasibility refers to a situation where no solution satisfies all the constraints of a given problem. This means that the set of conditions or restrictions imposed on the problem cannot be met simultaneously, making it impossible to find a viable solution within the defined parameters.

Infeasibility in linear programming occurs when no solution satisfies all of the given constraints simultaneously. In other words, it happens when the constraints conflict with each other, making it impossible to find any feasible solution that meets the conditions of the problem.

Infeasibility in linear programming occurs when no solution satisfies all the given constraints, meaning there is no feasible region where the constraints overlap.

the number of solutions to the linear programming models that satisfies all constraints is ZERO.

a given problem or scenario cannot be solved or achieved

Infeasibility means that the number of solutions to the linear programming models that satisfies all constraints is zero.
