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 275 units of model Alpha, 150 units of model Bravo, 175 units of model Charlie, and 250 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.
