Semantic Validation of Emergent Properties in Component-Based Simulation Models

The software emergent properties and them reflection in the non-functional requirements and quality models

“…Objective-based approach to detection of emergent properties of software component-based systems is semantic validation of emergent properties in component-based simulation models [20]. Emergent properties validation focuses on showing that the unexpected behavior is valid (or invalid) for a given set of conditions.…”

“…In component-based complex systems, emergence validation approaches are classified in three key categories, namely, grammar-based, variable-based and event-based. Authors of [20] simulate the complex system and, at each simulation step, analyze the system state. Then authors compare the simulated system state with a calculated system state using reconstructability analysis.…”

“…Despite a plethora of definitions and methods, a practical approach to identify and validate emergent properties in newly composed simulation models remains a challenge [20]. There has been active research in defining emergence, all of them explain the nature of emergence and emergent properties, but are not formalized and are not suitable for modeling and prediction of emergent properties.…”

An integrated approach for the validation of emergence in component-based simulation models

“…There is a critical need to understand the interaction between components at the micro-level the composed models, and how this interaction leads to emergence at the macro-level. Moreover, existing approaches (Chen, Nagl, and Clack 2007, Kubik 2003, Seth 2008 are currently only applied to simple models such as flocks of birds, and have limiting assumptions and constraints when applied to more complex systems (Szabo and Teo 2012b). A key challenge is the need for abstractions of the micro and macro levels.…”

“…Mogul 2006), few instances have been measured and explained (Szabo and Teo 2012b). A difficulty lies in defining the variables that describe the system sub-components, or the micro-level, and the system as a whole, or the macro-level, and the relationships between the micro-level and macro-level.…”
