Coronavirus Epidemic 2019/20 for Switzerland von Louis

COVID-19 Epidemie in der Schweiz (Louis Gerber)System Dynamics Modell der COVID-19 Epidemie in der Schweiz. Auch wenn das Modell nach bestem Wissen erstellt wurde, übernehme ich keine Verantwortung für gesundheitspolitische Entscheide, welche daraus abgeleitet werden. Aber als Beitrag zu einer sachlichen Diskussion scheint es mir allemal geeignet. Das Modell ist ein Update des Schweinegrippe Modells von 2009. Es wurde um Massnahmen und Effekte angereichert, welche damals nicht zur Diskussion standen. Da ...

Refugees vs. Migrants - a possible solution to Germany's refugee dilemma von Kai Neumann

We are in the midst of an escalation of attitudes against refugees and politics with our media reporting that we have reached limits, with the use of suggestive questions in almost every interview. The existing models on the refugee crisis on know-why.net predicted that: https://www.know-why.net/model/CY7aksh7qgaQkCiULQUJN1A  The consequence will be right wing movements and while media thinks it should warn of a threat of right wing movements it actually fuels them. However, now we need to find a clever ...

The effect of low oil prices and end of Iranian sanctions (Fareed Zakaria's arguments) von Kai Neumann

The start of the model is based on an article by Fareed Zakaria. Feel free to edit the model through the collaborative modeling link " By Fareed Zakaria Thursday, February 4, 2016 One of Donald Trump’s stock campaign lines is that the Iran nuclear agreement was “terrible.” I’m beginning to wonder whether that’s true, but from the other side. Iran has ended up with a much worse deal than it expected. Remember, Tehran entered the negotiations in the heady days of high oil prices. As the Iranians are discov...

A solution for Ghana's and probably other country's future von Kai Neumann

Just returned from a science/business trip from Ghana - this time also visiting some 'hinterland' as well as tourist attractions. Great people (I mean that) and potentially a great country as well. They have the beaches, the forests even near the beaches, they speak English, they have great local food, and at least in the south it was despite dry season extremely green.  But for the first time in my life I wasn't willing to jump into the ocean - too much garbage in it. I wasn't jogging - too much polluti...

Quantitative model on smallholder's income (Workshop example using Monte Carlo) von Kai Neumann

This quantitative model is from a workshop for the University of Cape Coast. It features a small quantitative model that starts with a steady constant development of a smallholder's income from growing one crop. Via step by step simulation it can be changed. The model, then, was enriched by a Monte-Carlo simulation of the possible influence from extreme weather and by the use of the range() function to look for all possible combinations to identify an optimal solution. Note: some of the factors have an e...

Software-Migration: Vermeidung von Bad Smells von Franc Grimm

Das vorliegende Modell zeigt einen kleinen Ausschnitt aus einem umfangreichen, realen Modell. Es geht bei dem Projekt um die Migration einer Software mit einer monolithischen Architektur hin zu einer modernen, modularen und Service-orientierten Architektur. Das Modell soll helfen vor allem die Risiken zu bewerten und die Dynamiken, die sich im Projekt ergeben können, aufzuzeigen. Die detaillierten Einzelmodelle haben konkrete Bibliotheken genannt und auch Risiken hinsichtlich Krankheit oder Weggang von M...

PiM demo model on IT processes p2: developing solutions von 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)

GDP growth with shrinking population von Kai Neumann

This model was developed as a reaction to a science meeting where the participants univocally doubted the potential for GDP growth in Germany with the prospect of a shrinking population. While I might criticize the concept of a GDP and see a lot of reasons for a shrinking economy I doubt that a shrinking population inevitably has to lead to a shrinking GDP. But see my arguments in the model and tell us what you would change or even better make the changes directly in the model via the collaborative link.
