Adding Stock and Flow Structure to Causal Diagrams Consider the causal loop diagrams in chapter 5. For each, redraw the diagram showing the important stock and flow structure along with the fcdback structure shown in the diagram. In particular, identify the main stocks and flows in the fol- lowing conceptualization case studies presented in chapter 5: 1. The workload management example. 2 The oil industy and horse racing exampls. 3. The traffic congestion example In each case, consider whether the explicit representation of the main stocks and flows enhances your ability to understand the dynamics of the system or merely clutters the diagram.
