discusses  decision making using system modeling. The author briefly mentions an  open source software tool, EMA Workbench, that can perform EMA and ESDMA  modeling. Find EMA Workbench online and go to their main website (not  the GitHub download site). Then do the following:

1) Under documentation, go to the Tutorials page.

2) Read through the Simple Model (in your chosen environment), and the Mexican Flu example. 

3) Decide how you could use this software to create a model to help in developing a policy for a Smart City.
