Answer:
Optimal solution point
Step-by-step explanation:
The sensitivity range for an objective function coefficient is the range of values over which the current optimal solution point remains the same.
Additionally, the range of optimality can be defined as the optimality range with respect to an objective coefficient that comprises of the range of values over which a current optimal solution point will always remain optimal.
Hence, the managers supervising various production lines are saddled with the responsibility of focusing on the objective function coefficient for optimal level of output or productivity.
