• Combined simulation


  Also known as hybrid simulation, involves integrating different types of simulation methods to model complex systems more accurately and comprehensively
• Combined simulation


  • Leverages the strengths of various simulation techniques, such as discrete-event simulation (DES), continuous simulation, and agent-based simulation (ABS), to capture the intricate dynamics of systems that may not be well-represented by a single method alone
• Discrete-Event Simulation (DES)


  Models systems where state changes occur at discrete points in time
• Discrete-Event Simulation (DES)


  • Commonly used for queuing systems, manufacturing processes, and logistics
• Continuous Simulation


  Models systems with continuous state changes over time
• Continuous Simulation


  • Often used for physical systems, chemical processes, and population dynamics
• Agent-Based Simulation (ABS)


  Models the interactions of autonomous agents with individual behaviors
• Agent-Based Simulation (ABS)


  • Suitable for social systems, market dynamics, and biological systems
• Benefits of Combined Simulation

  • Enhanced Realism: Combining different simulation methods can more accurately capture the complexity of real-world systems
  • Comprehensive Analysis: Provides a holistic view by integrating various aspects of the system that might be overlooked in a single-method approach
  • Flexibility: Allows for the modeling of both macro-level (system-wide) and micro-level (individual components) behaviors
• Applications of Combined Simulation

  • Healthcare Systems: Modeling patient flow in a hospital using DES for queuing and ABS for individual patient behaviors to optimize resource allocation and reduce wait times
  • Manufacturing and Logistics: Combining DES to model production lines and continuous simulation for energy consumption analysis, providing insights into both operational efficiency and sustainability
  • Urban Planning: Using ABS to simulate pedestrian and vehicle movements, while employing continuous simulation to model environmental factors like air quality and noise levels
  • Epidemiology: Integrating continuous simulation for disease spread dynamics with ABS to represent individual behaviors and interventions, aiding in the development of effective public health strategies
