Qualitative cause and effect model on the SDGs This is a model that we (...) use for a paper yet to be published. Please copy (on know-why.net you find the link to insert it into your account) it into your free account of iMODELER in order to enhance it and weight the connections to fit a concrete region or nation. You may also consider two concrete countries, e.g. a developed country and a developing country. Background:The UN’s Sustainable Development Goals in their generalized form need to be further reflected in order to identify synergies and trade-offs between their (sub-)targets, and to apply them to concrete nations and regions. Explorative, qualitative cause and effect modeling could serve as a tool  ...»

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 pollution in the air. Almost 50 percent the people unemployed and most of the others selling stupid plastic stuff. It is a pity. Plastic garbage, old oil spilling cars everywhere. So, no hotel could afford to pay for ...»

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

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 explanation of the formula within their properties. Range() version of the model: http://www.imodeler.info/ro?key=CRfyLZCT7YB5n6AHKGAXm2Q Version without range() or Monte Carlo: http://www.imodeler.info/ro?key= ...»

This is a qualitative model from an iMODELER workshop for a group of scientists from different fields from the University of Cape Coast, Ghana. Feel free to continue the modeling via this collaborative link. Here is the read-only link to the original model: http://www.imodeler.info/ro?key=CIcLFmS12YTHp4U7SkgXR9w  What is the question the model should answer: What can be done in order to mitigate the effects from illigal mining (surface mining) on the quality of water from rivers? What are the system’s boundaries? only illigal mining only mining activities with relevant impact on rivers  …. What is the time scope? short term: 1 year medium: 5 years long: 10 years What are the categories/colors? Additional note ...»

Just a small quantitative model for a workshop to show the features of the PROCESS iMODELER (PiM) factors with the example of a farming process. Please post any further questions :-)

Just a small model to facilitate a discussion during a workshop in Ghana. The thesis was that seasonality would lead to less exports of crops and the counter argument was that it might lead to a necessity to export if domestic demand isn't able to consume all the crops. However, if irrigation leads to less seasonality it might be possible to export more. Tricky, isn't it?

Just the start of a model to answer to a post on linkedin: https://www.linkedin.com/pulse/why-germany-cannot-lead-west-michael-weidokal Germany has of course not the size to determine world politics, but it is big enough to serve as a role model that could foster change around the world. My concern, however, is that neither Angela Merkel nor Martin Schulz are of a visionary type to change towards a role model. Once, we follow the trend of higher military spending, and if we continue to ignore the proposals to emancipate Africa, and if we do not distinguish between sources and sinks e.g. when spending money in southern Europe, Germany would just stay a bit longer better off. Germany could show how quality and  ...»

This is just a very small model to show the iM-Optimizer feature coming with version 8 of the iMODELER. For more see the Menu....Presenter. Don't hesitate to ask for more explanation here on KNOW-WHY.NET and please post your own enhanced versions of this model.
