Relationship Modeling

• Capture understanding• Overcome individual limitations• Qualitative in nature

Page 3: Causal Loop Diagram

Intent of this Video

• Understand elements• Alternative notation• Notation short comings• Preferred notation• Develop a Causal Loop Diagram

Page 4: Causal Loop Diagram

Elements

• Entity – non negative noun or noun phrase• Influence – relationship between entities• Simplest CLD – 2 entities + 1 influence

Page 5: Causal Loop Diagram

Notation

Page 6: Causal Loop Diagram

Notation Resolution• Variables

• Instantaneous & Accumulators (Stock)

• Differentiate the two• Rectangles for Stocks

Goal Seeking Loop

Page 10: Causal Loop Diagram

Emergence

• Properties arising from interactions

Page 11: Causal Loop Diagram

Additional Thoughts

• Telling Loops - count the “-” signs• Odd number is a balancing loop• Even number is a reinforcing loop

• Delay – use || or delay on the line• Qualitative only, not quantitative• See Stock & Flow Diagram Video
