Just a small qualitative model for a discussion on linkedin on the economics of Tesla's Powerwalls. Here is the original article the discussion is based on: http://www.forbes.com/sites/christopherhelman/2015/05/01/why-teslas-powerwall-is-just-another-toy-fo... 

Just a small model on the competitiveness of eco technology and the effect of regulations that demand more eco friendly technologies.  Feel free to use the model to provide a more differentiated model.

This small model features the latest simulation game features of the iMODELER service version 6.0.3.. Here is a link to a quick guide: http://ilsa-consulting.com/Downloads/iMODELER_simulation_games_tutorial.pdf  With version 6.0.3 comes the possibility to define surfaces with input and output texts and/or pictures. Ah, and you may opt (Menu .... preferences) to show curved arrows :-)

This model might lead to a new kind of politics. More to come. In between you may simply play a bit with the model and try the new feature of a collaborative modeling link directly beneath the model on know-why.net. Don't be shy....

Here is a small model of the arguments taken from an online article from the SPIEGEL: http://www.spiegel.de/wirtschaft/wachstum-der-weltwirtschaft-der-kapitalismus-ist-kaputt-a-1028098.h...

This quantitative model is a small excerpt from a 1000+ factors model of a larger project. It allows to simulate the changes of a job market due to changes of available jobs or people seeking for jobs, people choosing to work only part time and a larger part of pensioners. While it would be fairly easy to model it through a classic system dynamics stock and flow structure it was fairly challenging to try it with the iMODELER's possibility to use stocks without delays. That is also the reason why I tried it the complicated way: in a model with classic stocks and their implicit delays some changes would take up to three years (the time step in our customer's model) to take effect. When you try this kind of comp ...»

Small model to show the limits and strengths of qualitative models when we look at loops.

Kleines qualitatives Modell für KNOW-WHY.NET und zur Vorbereitung auf einen Workshop, für den das als gewünschtes Thema angekündigt wurde.

Small model on product development (in this case Consideo's improvement of data import functionality of the iMODELER) and how to use same basic features of the iMODELER like change of perspectives, use of categories and filters and some of the analysis functionality like the new bar charts and the benefit from the new weighting that comes with version 6. For more see the presenter (Menu ... Presenter).

Dieses kleine Modell berücksichtigt die neuesten Meldungen zum Thema veröffentlicht von der eher konservativen Wirtschaftswoche: http://www.wiwo.de/politik/deutschland/studie-mindestlohn-entlastet-den-staat/5264072.html http://www.wiwo.de/politik/deutschland/mindestlohn-ueberraschung-bei-der-konjunkturprognose/11523840...
