In many product markets, availability is a key competitive variable, and companies control production based on inventory adequacy and delivery delay. Draw a "causal loop diagram" to represent this system that includes the following variables: Orders, Inventory, Product Attractiveness, Backlog of Unfilled Orders, Product Availability, Desired Production, and Production. Add Delays when necessary. Also mark the polarities (+ and -) of the relationships and the nature of the feedback loops (i.e. balancing or reinforcing, with a B and R). Assume any additional information that is not provided. (6%)
