When the future situation was taken into account, the
following conclusions were reached. There were two best
alternatives according to the company’s primary performance measure: Alternatives 6 and 8. When considering
other performance measures related with these alternatives,
it was also concluded that there was not a significant difference between two according to “average unnecessary
time spent in system”. However, Alternative 8 presented a superior performance than Alternative 6 according to “average number of batches waiting to be processed in front of
bottleneck machines”. Therefore, Alternative 8 was selected as the best alternative.
These two different situations are shown by column I
and II in Table 3, which gives the best alternatives according to each performance measure.
