GO-DEVS: Storage and Retrieval System for DEVS Models Using Graph and Ontology Representation.

Area of Science:

• Computer Science
• Modeling and Simulation
• Software Engineering

Background:

• Discrete Event System Specification (DEVS) is a formal language for component-based design, emphasizing model reusability.
• Existing systems lack systematic methods for storing and retrieving diverse DEVS models, hindering effective sharing and reuse.
• The need for a robust system to manage and access a growing repository of DEVS models is critical for the modeling and simulation community.

Purpose of the Study:

• To propose GO-DEVS (Graph/Ontology-represented DEVS storage and retrieval system).
• To enable systematic storage and efficient retrieval of DEVS models.
• To facilitate effective sharing and reuse of component-based DEVS models.

Main Methods:

• Developed GO-DEVS, a system utilizing graph and ontology representations for DEVS models.
• Integrated ontology representation during DEVS model development for enhanced sharing capabilities.
• Implemented a method for storing and querying DEVS models on a Relational Database Management System (RDBMS), supporting IO and structure queries.

Main Results:

• GO-DEVS successfully stores and retrieves DEVS models using graph and ontology structures.
• The system supports novel IO and structure query types for effective model searching.
• Experimental results demonstrate the efficient query processing capabilities of GO-DEVS.

Conclusions:

• GO-DEVS provides a systematic solution for managing and retrieving DEVS models.
• The proposed graph/ontology representation and query methods enhance DEVS model sharing and reusability.
• This system addresses the current limitations in DEVS model management, paving the way for broader adoption and collaboration.
