Specialization and Pruning
A major strength of the SES is that it generates a family of hierarchical models rather than single composition. To understand how this is accomplished, we discuss a second main construct called specialization to complement and interact with the earlier introduced operation of decomposition. Specialization enables you to expand the alternatives, or options, for selection. We show how a pruning interface supports understanding the combinatorial space of possible selections. You need not make all available selections at one session and can return later to amend and add to a pruning file. This allows you to generate multiple possible Pruned Entity Structures that can be transformed into simulation models.
