Data-specified association between instances of the same submodel

Model : data_specified_assoc2
Simile version : 3.1+
Date added : 2003-06-20
Keywords : Simile techniques ; Association submodel ;


This model demonstrates how to set up an association between submodel instances using a data file containing pairs of instances.

In this example, the association is between one multiple-instance submodel and itself. The submodel could, therefore, represent the nodes on a network, with the asociation indicating which nodes are connected (by arcs) to which other nodes.
