1. AnyLogic Introductory Presentation
Prepared for
Systems Engineering Department
University of Lagos
9a.m. Friday 27th January, 2017

2. Agenda Why simulation? Simulation paradigms AnyLogic overview
AnyLogic basics: navigating your way
Build a simple model
Using AnyLogic in your research
Summary

3. Why simulation? What is the problem?
Is simulation the best solution? Do I need additional tools?
What type of simulation is appropriate?
What level of detail do I need in my model?
Also consider if the problem can be solved using other tools- Excel spreadsheet, Mental models, Physical Models, Analytical models, Monte carlo simulation.
You can find an analytical solution if:
The number of parameters is ‘manageable’
Behavior is linear
Dependencies are clear, easy to build a mental model
But what if:
Too many parameters
Non-linear, non-obvious influences
Time and causal dependencies
Counter-intuitive behavior
Uncertainty (stochastic system)

4. Simulation paradigms Discrete event (DE) Continuous event (SD)
Agent based event (AB)
Multi-method (MM) - DE/SD; DE/AB; SD/AB; DE/SD/AB
DE models the state events that occur in each discrete space in time
SD models the continuous sequence of state changes in time, with the ability to model the non-linear relationships that exists in complex systems, enabling a visualization of how a system will evolve over time

5. Simulation paradigms High abstraction level [minimum details
macro level
strategic level]
Aggregates, global feedback loops, influences, trends…
Medium abstraction level
[medium details
meso level
tactical level]
Low abstraction level
[maximum details
micro level
Operational level]
Individual objects, exact sizes, velocities, distances, timing…

8. Simulation paradigms- AB
Flow chart
State changes
We focus on individual objects (also known as agents) and describe their local behavior, local rules. Sometimes, we also model the dynamics of the environment

9. Simulation paradigms- MM
Combination of methods AB SD DE

10. AnyLogic overview
Only Software to have all three simulation modelling paradigms
An array of libraries to model a variety of situations. Libraries are added regularly
Experiments- Optimization, Calibration, Parameter variation, Monte Carlo, Sensitivity, Compare runs, Custom experiments
3D graphics and animation
Basic knowledge of Java codes is advantageous
Many more…………..

18. Using AnyLogic in your research
Simple models can be built using the free PLE version
For specific research the University Researcher version can be provided
Practice! Practice! Practice! With the PLE version
Free access to help with building complex models

19. Summary Decide if simulation is needed.
Establish what simulation paradigm will be sufficient. AnyLogic accommodates all.
Practice makes perfect! The key is to start simple and add complexity as you build
AnyLogic enables a variety of experiments
Use AnyLogic in your research
