Capability Maturity Models
Posted by Francisco Perez <francisco77pp@yahoo.com> Hello there. I was wondering whether there were any information on developments of Capability Maturity Models for Modeling and Simulation in System Dynamics. I am trying to do some framework but would like to know your comments and ideas. If any of...

Characterizing System Dynamics
Posted by Francisco Perez <francisco77pp@yahoo.com> Hi. I would like to consider Invigilator comments about SD as Universal Modelling Science. I think that if that's the reference to put SD on the highspeed lane, a fast crash is for sure. Trying to put the SD Community in that track is like saying t...

Aggregation and Behavior
Posted by Francisco Perez <francisco77pp@yahoo.com> HI All, I was wondering if any of you have ever questioned the risking of SD modeling when aggregating in order to model the macro system and not to dive into much detail. If Chaos theory is correct, than specific events, as minimal and detail-worl...

Lyapunov Exponents
Posted by Francisco Perez <francisco77pp@yahoo.com> Hi Ahmet, I would recommend you to read Control Theory and Applied Control (Theory). Almost in any text you will find the Lyapunov Stability Analysis, via Lyapunov Exponents. It is relatively complex and difficult to apply in System Dynamic Models ...

Process and performance simulation
Hello George. I'd like to add a comment to your Query. Business Process Simulation is not necessarily based on Discrete SImulation, in fact SD may be used for BizProzSim. On the other hand, Business Performance Simulation is not necessarily based on System DYnamics, in fact Discrete Sim could be per...

Supply Chains for Tour Operators
Posted by Francisco Perez <francisco77pp@yahoo.com> Hi Davide, I think you should consider the following literature: SYSTEMS-BASED MODELING FOR PARTICIPATORY TOURISM PLANNING AND DESTINATION MANAGEMENT by T. JAMAL et al. Tourism Analysis, Volume 9, Numbers 1-2, 2004, pp. 77-89(13). Other papers that...

Strategy magazine article about Jay Forrester
Posted by Francisco Perez <francisco77pp@yahoo.com> Hi, I think it is movitvating. But regarding what just Justin said about calling SD SimSci, I think we, as SD'ists, should keep in mid that SD is just part of the ample space of SimSci. Take into account, dynamic systems sim, agent mod & sim, d...

Interfacing with Excel
Posted by Francisco Perez <francisco77pp@yahoo.com> Thanks for your response. Let me try to clarify a bit more my query. I know that optimization is now embedded in Powersim and Vensim, but the main purpose fur such engines is for model optimization (be it policy otimization, or the like) and calibr...
