2.4 A Linear Programming Problem with no solution. The feasible region of the linear programming problem is empty; that is, there are no values for x 1 and x 2 that can simultaneously satisfy all the constraints. Thus, no solution exists.21 2.5 A Linear Programming Problem with Unbounded Feasible Region: Note that we can continue to make level curves of z(x 1;x 2) corresponding to larger and

A transportation problem allows only shipments that go directly from supply points to demand points. In many situations, shipments are allowed between supply points or between demand points. Sometimes there may also be points (called transshipment points) through which goods can be transshipped on their journey from a supply point to a demand point. The optimal solution to a transshipment
