Refugees from different regions - a collaborative model by Kai Neumann

The aim of this model is to have a closer look at the root causes for the flow of refugees from specific countries and regions. Please add your arguments.

Example model on Value Chains (Qualitative Model) by Kai Neumann

Just a small example model to show the benefits of qualitative modeling of value chains (https://en.m.wikipedia.org/wiki/Value_chain)  Note: There is also (soon) a quantitative model on KNOW-WHY.NET: https://www.know-why.net/model/CwgPFMPsVgABXfHJVpjxhqw

PiM Mini Model on Costs based on Availability by Kai Neumann

This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown in another model the directly associated costs or like shown here the costs of the availability of the resources. For the availability of resources you simply sum up the cost of a resource times the number of principally available resources. The use of level resources can either be equally their principal availability or their use. For this you can use the possibility to connect a process...

Amelie's CO2 Modell 2 (zum Gewinnen eines Fairphones) by Kai Neumann

während einer Gartenparty stellten ein paar Kinder zwischen 7 und 10 Jahren Fragen zu unserem Sampada Ofen, dem Veganersein, usw. Am Abend rückte ich dann mein Tablet raus und wir haben gemodelt. Amelie hat die Fragen gestellt und alle durften mal Faktoren anlegen. Die Kinder konnten hernach die meisten Zusammenhänge wiedergeben (möglicherweise zum Leidwesen einzelner Elternteile) PS: das Fairphone ginge dann an Amelie

qualitative mini model on sustainability by Kai Neumann

Just a small but powerful model to show the features of different qualitative weightings between short, medium and long term.

PiM demo model on IT processes p2: developing solutions by Kai Neumann

This small PiM model shows how an IT company that develops apps or designs websites or installes software can be modeled in order to identify bottlenecks or constraints and to simulate the costs and income (benefit management)

PiM Mini Model on Associated Costs by Kai Neumann

This mini model shows one of two ways to calculate costs within PROCESS-iMODELER models. Costs can be either as shown here the directly associated costs or like shown in another model the costs of the availability of the resources. For the associated costs you simply connect the process factors to a normal factor and use the costs() function times the process. The costs() value of each process step is the sum of the costs (a parameter of the resource- and level-resource factors) that are connected with t...

Quantitative Model on Economics with degrowth by Kai Neumann

Quantitative model on economical developmentsThis quantitative model compares the average income and wealth of the people that earn above the average or those who lend money with those below average or those who borrow money. It includes interest rates initial inequality savings quota money creation (the possibility of banks to lend more than they hold) productivityThe model allows to understand the basic developments and to try scenarios on degrowth, by trying a negative productivity re-coupling of fina...

Feed the world - qualitative model on the arguments by Kai Neumann

I was recently preparing my contribution to the  System Dynamics Conference presenting our comprehensive quantitative GLU Model (global land use). At the same time I am repeatedly  confronted with the argument that in order to save the world we need industrialized farming with the use of pesticides, fertilizer, and high precision farming, because otherwise we would not have enough yields to feed the world and thus would need more deforestation. Well, while the quantitative model shows that without major ...
