Corona virus (COVID-19) - a system dynamics simulation model using not just the bass diffusion von Kai Neumann

Link to corresponding paper: https://www.consideo.com/papers-33.html (English) https://www.consideo.de/papers.html (German) Summary - it really is severe The model shows how crucial the availability of a cure and vaccine has become. The death toll is directly related to the intensive care capacities that are totally unrealistic to keep up with any slow down of infections. The flu has a toll of 0.1 percent, Covid-19 allegedly a toll of 1.1 percent though some areas like Italy already show a rise close to ...

Reflexion on thorium reactors von Kai Neumann

this is just a first scetch of a cause and effect model ... if you look at the matrix of the factor thorium reactor you will recognize that this model is dominated by balancing feedback loops (...) you may contact me (kai@ilsa.de) to get a copy of the model or even to collaboratively model it with me and others in any way: many insights and happy modeling Kai

Open Source Horizon Scanning Trend Forecast Foresight Model (1) von Kai Neumann

This model should help to collect news from all over the world and put them into cause and effect relation to each other, and to the factors that define the economy, the societies, the environment, and everyone. Those factors we call targets, colored yellow. Whenever some interesting news pops up we may add further target factors to connect them with the central target of our all well being. The model should remain as general as possible. A small manual is provided with the Menu ... Presenter. News could...

General model on transition, tipping points and crossing the chasm von Kai Neumann

Just a small general model on tipping points (using the Bass function that can be found e.g. in Sterman's 'Business Dynamics'). The model distinguishes between first movers, early adopters and the tipping point (Malcolm Gladwell) of an adaption by the majority of potential adopters. Getting from early adopters to the majority can be named 'crossing the chasm' (by G.A. Moore). The model can be used for both, explorative qualitative modeling of factors the hinder and foster the tipping point, or a continua...

Fridays for Future - debunking politician's bullshit von Kai Neumann

it is doable, in fact it would cost less, but memes and ill minded politicians serve single interests. unfortunately, there is no clear argumentation against the memes out there. this is just a rough sketch, but as a scientist I have examinded the path to a sustainable future in depth. please ask for more and join the modeling!  students and media need to be a role model for the green factors and explain the turqouise factors: ....

Waterkant Festival 2017: collaborative workshop model von Kai Neumann

This small model should just help to facilitate a workshop at the WaterkantFestival 2017 in Kiel, Germany. The topic is to show how a new enterprise can become successful with an innovation. This model looks exactly at the enterprise. Another model will look at the generation of an innovative product (applying the so called Idealized System Design). And a third, quantitative model will show how counterintiutive dynamics behind a start up can be (the diffussion model that shows how to burn investor's mone...
