Agent-Based Simulation Techniques

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Jim, I will try to approach your questions: Agent-based Modelling is somehow based on Discrete-Event-Simulation as an agent normally reacts to events, so to turn it the other way around entities in a Discrete-Event-Simulation ...

The ""usefulness"" of SD

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Invigilator, We had a similar idea when writing the paper ""comprehensibility as a discriminaton criterion for agent-based modelling and system dynamics: an empirical approach"" for the SD conference in Bos...

SD and other modelling approaches

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Jean-Jacques, I have my problems with the technicalities again: What do you mean by aggregated time? This is in your opinion central for continuous systems. But this also in my opinion a matter of degree. In System Dynamics we...

Combining Discrete and Continous

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Jean-Jacques, I have been thinking about the relation between discrete and continuous for a while myself now and i think there are cases, where also from a strategic or aggregated point of view, the discreteness of some phenom...

SD and other modelling approaches

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Jean-Jacques I definitly agree with you that a rigouros analysis of the problem makes the modelling quite easy, but still i want to keep the point, that a - even if it is subconscious;)- choice of the method to use before the ...

SD and other modelling approaches

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Jean-Jacques, You have lately posted two mails, which i found both very inspiring for my thoughts, especially the critism of my idea to classify problems in order to arrive at the right method. Nevertheless in the next mail yo...

Combining Discrete and Continous

Posted by ""Tobias Lorenz"" <space56@freenet.de> Dear Louis, We have been experimenting with combining all three methodologies (DES, ABM and SD) within single modells and i'd say it depends very much on the problem. Of course u always run the risk to loose the problem focus and m...

SD and other modelling approaches

Posted by ""Tobias Lorenz"" <space56@freenet.de> Hey everybody, First of all with ABM, i meant the Agent-based Modelling, which is becoming more and more important. Sorry for the exceptional abbreviation. I still agree with Geoff and i would like to even sharpen that point, i wou...

SD and other modelling approaches

Posted by ""Tobias Lorenz"" <space56@freenet.de> Hey Everybody, I am fairly new to the list (two days to be exact), but unfortunately well acquainted with the problem (as far as i see it at least) ;) One main task in eyes would or should be to collect the opposing simulation meth...
