METHOD AND COMPUTER PROGRAM PRODUCT THAT DETERMINE VALUES OF CHARACTERISTIC VALUE COMBINATIONS FOR USE IN THE PRODUCTION OF PRODUCTS

Methods and apparatus, including computer program products, implementing and using techniques for determining a quantity to be produced for each of two or more product types, where each product type is specified by one or more characteristics. An input specifying a desired distribution of the total quantity among the one or more characteristics is received. If the desired quantity to be produced of a product type is a non-integer value, the desired quantity is rounded to an integer to generate a final quantity to be produced for each product type. The final quantity preserves both a total quantity and the desired distribution of the total quantity among the one or more characteristics.
