Generating the diagram

 
Figure 5:  

The steps required to produce the influence diagram Figure 6 are shown in Figure 5 as follows.

• Note that any options and controls established earlier in Figure 2 or Figure 3 remain in force.
• FOR:  commands are used to establish the bases (collections) .
• The GCLEAR:  command is used to clear the graphics screen of the influence diagram previously drawn.
• We want to draw an entirely new influence diagram, with different node coordinates and so forth. Thus we use the XGRID:  command to delete currently existing node coordinate information before designing the new diagram. The $ symbol is a wildcard, representing all nodes.
• The GRID0:  command is used as described previously to design the influence diagram.
• Several ARC:  commands are used to connect nodes on the influence diagram. The arcs between the batch nodes and the nodes representing the individual quantities A,B,C,D are to be unlabelled directed. The arcs between the batch nodes and the node G representing the collection of individual quantities are to be unlabelled directed and display path correlations.
• Finally, the ADJUST:  command is used several times. Each node A,B,C,D,G is adjusted initially by , and then partially by , , and in turn.
