• Random
• Some rules

Question 2

Answer 2

Discrete event simulation
Object oriented simulation
Cellular automata

Question 3

What is validation?

Answer 3

The process of determining whether a simulation model is an accurate representation of the system

Question 4

What different validation are there?

Answer 4

• Face validity (regarding technique) - check if model structure outcome are plausible, informal, relies on techniques like reviews
• Epirical validity (regarding technique) - data-based validation, applied to a model with high face validity
• Behavioural validity (model aspects) - concerns dynamics of the model (input-output)
• Structural validity (model aspects) - over design/structure of the model, relationships between variables, agents.., concerns the agents architecture

Question 5

What are the categories of the agents architectures?

Answer 5

• Behavior descriping - rules
• Behaviour configuring - select and configure a plan
• Behavior generating- first principles planning
  Behavior optimizing –> evalutate and select

Question 6

Give to situations where you would not use ABM - what would you use instead?

Answer 6

• Quening systems - discrete event oriented

* Spread of corona virus - cellular automata

Question 7

Describe discrete event simulation

Answer 7

• state is only updated during event processing
• Event queue contains event to be processed.
• Very efficient
• Event scheduling –> more advanced models with process orientation

Question 8

Describe object oriented simulation

Answer 8

• Rigorous formal definition
• Sequence of events as input, triggering states changes. Description in king of state-transition tables
• Large community, very active in different applications domains
• Atomic models are coupled into larger systems

Question 9

Describe cellular automata

Answer 9

• Homogentiy - every cell has the same set of states and the same transition function
• Locality - state transition are local in time and space
• Emergence - macro-level phenomena can be obserbed that cannot be derived micro-level transition functions
• Different setups - grid geomentry, forms of neighborhood, bounding conditions, state sets , initial configuration, transition rules
• Paralell update of all cells
