If costs are increased, then this implies that using the cell would increase total costs. If costs remain the same. this would implv that an alternative option with the same total cost as the current plan exists, However, if analvsis reveals a cost dew crease. this implies that an improved solution is possible. The test for optimality.r requires that every unused cell be evaluated for po- tential improvement. Let’s see how the evaluation is carried out. Cell evaluation proceeds by borrowing one unit from a full cell and using it to assess the impact that shifting units into the emptv cell would produce. For instanceI if a shift of one unit causes an increase of 55, then it can he assumed that total costs would be increased hv $5 times the number of units shifted into the cell. ...
