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...

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

Ministerpräsident Kretschmer will sich Diesel kaufen (bei Anne Will) by Kai Neumann

Anne Will am 5.5.2019 https://daserste.ndr.de/annewill/Streit-um-CO2-Steuer-wer-zahlt-fuer-den-Klimaschutz,annewill5986.html - trotz Maja Göpel eine enttäuschende Sendung, da keine klaren Zusammenhänge aufgezeigt wurden. Auf der anderen Seite wurde allerdings erschütternd deutlich die selbst für die CDU anachronistisch konservative Haltung des Ministerpräsidenten Kretschmer und sein offenbar mangelndes Wissen. Seine Position zusammengefasst:  Ja, die Bevölkerung will Klimaschutz, und wir steigen ja auch ...

London's Housing Crisis - a collaborative modeling experience by Kai Neumann

On LinkedIn (https://www.linkedin.com/groups/2639211/2639211-6171315685852012548?trk=hb_ntf_COMMENTED_ON_GROUP_DI...) Bob Bollen asks for ways to model London's housing crisis. While some suggestions are rather complicated (some imho outdated) I'd like to suggest to just start with it in a way that not just experts but also stakeholders can read a model and contribute to it. So here is the start of a collaborative model.  Please ask for any further assistance / guidance using the comment functions on kno...

Solution: driving cars by Kai Neumann

A model explaining some of the obstacles of the transformation towards electric vehicles (EVs) This model is part of a series of models that could serve as examples for small models on global challenges as they could be modeled by pupils. Of course, depending on their age and the time that is available as well as the help you offer they could come up with more details. What is the model asking?The model asks for the development of the uses of gasoline cars and electric vehicles (EVs) using the KNOW WHY Q...
