Problem X0.[Model Formulation Only] Profit-oriented Millard Construction is contemplating building a planned community with the help of federal funds. These funds are to be distributed only if Millard meets federal standards for low cost housing. There are three types of units -- houses, town-houses, and high rise condominiums. There are three styles for each of the houses and town-houses -- low cost, standard, and deluxe. The high rise condominium will have only standard and deluxe models. Millar needs to determine the number of units of each kind of housing to build for the community at this planning stage. The amount of total ground area (including allowances for parking and green belts) per unit of each type is given in the following table: Ground Area (Sq. Ft.) Low Cost Standard Deluxe Houses 1800 2200 3000 Town-houses 740 1600 2230 Condominiums 1000 1500 The profit to Millard per unit of each kind is summarized in the following table: Unit Profit ($1000's) Standard Deluxe Low Cost 5 Houses Town-houses Condominiums Millard has 300,000 square feet for construction. To make the project "work", Millard wants the area of houses to occupy between 30% and 50% of the total area, the area of town-houses to occupy between 25% and 40% of the total area, while the area of condominiums only need to occupy 10% to 25% of the total area. The federal government requires that at least 25% of the total units built in the complex be low cost units. To reduce costs of materials purchased and to ease the works of subcontractors, Millard would like between 40% and 70% of total units built to be standard models (units). X0.1) Refer to Problem XO.
