Abstract [en]

Reynolds’ flocking model is a widely used behavioral model,

originally made for simulating flocks of birds. In this study

we examine the possibility of modifying the model to simulate

the scenario of a flock of sheep in the presence of

a predator. Apart from introducing a human-controlled

predator, the simulated animals were modified to move in

two instead of three dimensions and behave like sheep instead

of birds. A simulator, using this modified version of

Reynolds’ model, was implemented so that the behavior of

the simulated sheep could be compared to the behavior of

real sheep. The comparison was done primarily by using

quantitative data gathered from the simulator. This comparison

showed the existance of several similarities between

the simulated sheep and real sheep. These results suggest

that Reynolds’ flocking model can be used as a basis for

this scenario.

Abstract [sv]

Reynolds flockmodell är en välanvänd beteendemodell som

från början skapades för simulera en fågelflock. I den här

rapporten undersöker vi om det är möjligt att modifiera

modellen så att den simulerar scenariot med en fårflock

i närheten av ett rovdjur. Förutom att introducera

ett människo-styrt rovdjur, ändrades även de modellerade

djuren till att röra sig i två dimensioner istället för tre, och

bete sig som får istället för fåglar. En simulator, som använde

den modifierade versionen av Reynolds flockmodell,

implementerades för att jämföra beteendet hos de simulerade

fåren med riktiga fårs beteende. Jämförelsen gjordes

primärt med hjälp av kvantitativ data från simulatorn.

Jämförelsen visade att det fanns ett antal likheter mellan

de simulerade fåren och riktiga får. Dessa resultat tyder på

att Reynolds flockmodell kan användas som grund för detta

scenario.
