The Evaluate command computes the adjacency score of the adjacency graph or the shape adjusted distance score and adjacency score of the block layout if these have been created. It displays the distance score without shape penalty, called the flow distance score, for the block layout in the Delta Objective field. The results are displayed in the Notes and Statistics views. This command is most frequently used after you have edited interactively the relationships or after you have dragged a department in the adjacency graph to a new location. The Evaluate command does not create a new graph or block layout, but rather computes the cost of the current graph and layout based on the current relationship values. If a block layout has been created, the command also displays in a dialog window the total distance score, the flow distance score, and the total shape penalty for the current layout. It also displays for each department the actual area, shape ratio, and perimeter ratio. If only an adjacency graph has been created, the command displays the adjacency score, the sum of the absolute values of all relations, and the efficiency score of the current graph. The Evaluate dialog windows are illustrated in Figures 5.41 and 5.42, respectively when a block layout or a adjacency graph only have been created.
