in the graph on the top of Figure 3, Job 4 is shown to be overfilled in Years 1-3 filled exactly in Years 4-5. By contrasting this graph with that for other solutions (such as the one at the top of Figure 4), the DM could evaluate the pattems of job fulfillment. The graph on the bottom of Figure 3 shows the relative values of the solutions with respect to each objective. The first bar indicates the level of fit as a percentage of the best level. The best fit, found by optimizing the model on the fit criterion while ignoring the fill criteria. The height of this bar is determined by zoro. The remaining bars show the level of fill as a percentage of exact fill; the height of these bars is found by: (Total jobs in Year v) -X (d' d ke Flu) (Total jobs in Year v)
These graphs were used by the to compare the criterion vectors and select his or her preferred one. The preferred solution was then used as the center point around which new trial solutions are generated for the next iteration. Three iterations were
