PiM: Building a new garden house (Learning Curve and Working Hours) 2 by Kai Neumann

Setting up the walls Start of working time Time it takes setting up the walls
The aim of this little model is to explore the project modeling possibilities of the PROCESS-iMODELER (it is called PROCESS-iMODELER though it is just a feature of the quantitative iMODELER). The project at hand is the building of a small garden house. The model probably isn't complete in its details as it just should show the functionality. Here it is the modeling of a learning curve and the definition of working hours for resources.

Biomass Web: Accra's Mini Model on Exports by Kai Neumann

Need to import outside Season Dependence on Season Surplus of crops
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?
