Cooper River Glass Works (CRGW) produces four different models of desk lamps as shown on the flowchart. The operations manager knows that total manthly demand exceeds the capacity available for production. Thus, she is interested in determining the product mix which will maximize profits. Each model's price, routing, processing times, and material cost is provided in the flowchart.
