iMODELER‘s features for team collaboration?

Since we are in the midst of our development of iMODELER 10 (probably skipping version 9) we wonder what you would say is crucial for teams to successfully work on complex projects. Let us start a discussion and we will reveal the features we are thinking of :-)

Best practice for econometric system dynamics models

Within a project on food security I happened to model Ghana‘s whole economy finding it hard to initialize (initial values of stocks) the model that of course considered a lot feedback loops. I understand that this wouldn‘t be a challenge for general equilibrium models that in turn struggle to feature feedback loops. My solution was slow and dirty letting the model run with fairly high initial values to approximate the initial values that result in an equilibrium. Also relevant I assume is the fact that thes ...»

You need to register for a free iMODELER web version account on www.imodeler.info. Then you can mark the model within the desktop version to be available in your cloud as well in order to Menu...share it from there.

Collaborative global risk model

https://www.globalchallenges.org/en/our-work/annual-report seems to be a nice source for an open source global risk model. There already is a global risk model on KNOW-WHY.NET: https://www.know-why.net/model/CvrkTr4eTvd18dsfXoB1DKA but maybe we should consider a new one that fills the gaps and adds levers for politics and society?

U-Kurve

Hallo, kann ich auch eine U-Kurve in eine Beziehung einbauen? Beispiel: niedrige Anspannung (Müdigkeit) und hohe Anspannung (Angst) sind Voraussetzung für schlechte Leistungsfähigkeit, mittlere Anspannung zu guter Leistungsfähigkeit. Diese Anspannung könnte dann wiederum externe Einflüsse haben, wie Lob/Tadel etc.,wobei Lob angemessen aktivierend (mittlerer Bereich) chronischer Tadel aber mittelfristig zu Angst (hohe Erregung) langfristig zu depressivem Verhalten führen könnte (zu niedrige Erregung). damit  ...»

Modelle übertragen auf ipad auf dem die

Hallo, ich hab ein Model mit meiner Desktop Version 7.0.5 auf meinem Mac erzeugt, und würde dies gerne für die Präsentation auf meinen Ipad (kostenlose Version) übertragen. Ist das möglich?

ein qualitatives Modell ganz einfach über einen kostenlosen iMODELER service account ( www.imodeler.info) , dann im Modell-Manager nach Anmeldung Häkchen bei Cloud setzen, und dann auf iPad in Safari öffnen. Tipp: in Safari dann "Zum Startbildschirm hinzufügen" wählen, dann wird es zur App, die viel besser als die App aus dem App-Store ist.

Model on possible developments of North Korea?

Has anyone a model on the possible developments of the North Korea crisis? I think it should involve a lot of soft factors as well.

There’s a way out on North Koreaby Fareed Zakaria By Fareed Zakaria Thursday, Sept. 28, 2017 The confrontation between the United States and North Korea is in a more dangerous zone than at any point in decades. Each side has announced tough positions, issued threats and underscored that its positions are nonnegotiable. Each side is now boxed in, with little room to maneuver. How to get off this perilous path? The Trump administration has made a huge mistake in ramping up its rhetoric without any solid strat ...»
