Some general remarks
First remark
Feel free also to react on other posts! Do not wait only for comments from Olga, Elena and me! Developing knowledge is a group process … so please give also feed back over this blog on the work of your colleagues!
Second remark
I see a lot of flows in models
I think we can distinguish 3 sorts of flows:
> Money flows (sales revenues, costs of purchases, taxes, subsidies etc)
> Information flows
> Fysical flows (goods)
