Classi Furniture Company (CFC) produces three types of sofas: luxury, classic, sport. They also produce two types of chairs: bergre and dining chairs. Due to the capacity limit, CFC can produce at most 1,5 million products per year. Sofas are produced in facility A with a capacity of 1 million units and the chairs are produced in facility B with a capacity of 750,000 units. CFCs management team requires that classic sofas and sport sofas must constitute at least half of the product mix for the three types of sofas. Also, management wants to have at least 40% of total products are chairs. Profit margins and maximum market demand potentials are given as follows:
Product Type | Capacity Limits (units in 000) | Profit Margin ($/unit) | Maximum Market Potential (units in 000) |
Luxury Sofa |
1,000 | 28 | 400 |
Classic Sofa | 27 | 370 | |
Sport Sofa | 25 | 130 | |
Bergere Chair | 750
