Variability Modeling for Engineering Applications

Abstract

The System Entity Structure (SES) is a high level approach for variability modeling, particularly in simulation engineering. The SES is under continuous development. In this context, an enhanced framework is introduced that supports dynamic variability evolution using the SES approach and connects the SES to a model base (MB). Using this framework allows building executable models. However, the main focus of this paper is to show how to use the SES to model complex engineering system configurations using a test bench for valves. Specifying the SES, it is clarified, that the system configuration can be decomposed into generalized design patterns. The design patterns were identified during the development of our MATLAB-based SES toolbox for construction and pruning of SES trees and were employed for testing and verification of the respective functionality.
