Transportation Problem-Solution

Solution of the Transportation Problem:

The fundamental steps of the transportation method are:

Step 1:     
Determine a preliminary basic feasible solution.

Step 2:   
Determine an entering variable from among the non-basic variables. If all such variables satisfy the optimality condition (of the simplex method), Stop; otherwise, go to Step 3.

Step 3:   
Determine a leaving variable (using the feasibility condition) from among the variables of the current basic solution; then find the new basic answer. Return to Step 2.
