Interpretation of loops: a dispute between qualitative and quantitative modelers by Kai Neumann

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

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...

利润 (Profit model in chinese) by Daoen Pan

这是一个有关公司如何增加利润的模型。“市场营销”，“员工激励”，“削减预算“等等方法和措施将对公司的短期，中期和长期利润产生直接或者间接的影响。 This mode is based on Profit (qualitative and quantitative model) from Franc Grimm.

The dynamics of cancer (collaborative model) by Kai Neumann

Just the start of a model since I was asked for a rather general model on this difficult topic. Since I am a layperson this model should be improved by either directly editing it via collaboration link or at least discussing it.
