specify a problem, as well as the dynamic hypothesis and time horizon, simple stock and flow to address the problem. The problem should be related to either Sustainable Development Goals $($SDGs$).$engineering education

Formulate the problem of study: the hypotheses must include time horizon and reference mode of the key variable$($s$).$

Specify key variables and their various states in written form

Formulate your initial stock flow diagram. Submit Word document with copies of your model and results embedded in the word document. It would be helpful to include key equations $($Vensim$,$ Stella or Anylogic file is not necessary at this point$).$ It would be good to provide a simple CLD that illustrates the problem.
