Hybrid (Differential Equations - Statecharts) modelling in Anylogic

Anylogic is a modelling tool which allows modeling systems that are hybrid ( continuous and discrete timed systems) . used mostly for agent based modelling environment. in agent based modeling, individual centric approach is what used, i.e we model the cars rather the system, which will allow us to model instances of the model differently .
In Discrete event modelling, we use statechart with a timer (to generate events) and maybe some plain variables . where as in continuose systems modelling we describe the model using a set of DE that can be solved given any point of time to get a perfect simulation .
this type of systems are especially important in agent based modeling which allows for more realistic simulation . while keeping the individuality of different agents .
