Cooper River Glass Works (CRGW) produces four different models of desk lamps as shown on the flowchart. The operations manager knows that total monthly 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. Demand next month is estimated to be 175 units of model Alpha, 250 units of model Bravo, 150 units of model Charlie, and 275 units of model Delta. CRGW operates only one 8 hours shift per day and is scheduled to work 20 days next month (no overtime). Further, each station requires a 10% capacity cushion.
