 Figure 1.7 shows an example of an SES with associated MB. In the application phase, executable models are generated with **transformation methods** such as **pruning** and **build**. Based on defined objectives, _the pruning method derives a unique system configuration from the set of possible configurations_. The result of pruning is called **Pruned Entity Structure (PES)**. Based on the information in the PES, the build method generates an Executable Model using basic systems from the MB.
 
-**Representation Schema:** An SES is represented by a **directed tree structure**, as illustrated in Fig. 1.7. The different **edges** are related to different **node types**. Each node can define attached variables, also called **attributes**. Real-world or imaginary objects are represented by entity nodes. _Entity attributes represent **properties** of the respective object_. The root and the leaves are always entities. **Relations** between entities are specified by **three types of descriptive nodes**, called **aspect**, **multi-aspect**, and **specialization**. The attributes of descriptive nodes specify relations between their parent node and children nodes or decisions for the pruning process.

 **Relations:** Aspects describe how entities can be decomposed in partial entities. Coupling relations can be specified in a couplings attribute. Multi-aspects describe the decomposition of an entity into entities of the same class. They define an additional attribute, called Number of Replications (numRep). The taxonomy of an entity is described by specialization(s) and concerns admissible variants of an entity. Rules for selecting a variant during pruning can be defined in a selection rule attribute. With the extended procedural knowledge representation according to Pawletta et al., attributes can be dynamically assigned values. For example, coupling relations of a multi-aspect can result dependent on the value of attribute numRep.
