The supply for the figure is 300 while the demand for the figure is 200. Comparing the two supply and demand the lowest figure is 200. Therefore, 200 units will be allocated to square DA.

The paths that recorded negative indices needed an improvement which is the second and the fourth paths. It can be concluded can the second feasible solution has the optimality solution. c) When the improvement index is zero then the case is regarded as degeneracy. Normally, in a feasible solution there are m+n-1 used routes. When the routes, supply, and demand are satisfied when the index is zero. When the non-optimal develops a feasible solution happens, we add the zero allocation to a path and regard it as one of the used routes where the cumulative number of used path are m+n-1 so that the algorithm can continue.

For this reason no improvement is needed.

When the improvement index is zero then the case is regarded as degeneracy. Normally, in a feasible solution there are m+n-1 used routes. When the routes, supply, and demand are satisfied when the index is zero (Hsieh, 1280). When the non-optimal develops a feasible solution happens, we add the zero allocation to a path and regard it as one of the used routes where the cumulative number of used path are m+n-1 so that the algorithm can continue.
