ABSTRACT
In this chapter we present several different procedures that can be used to find the settings of the input variables which produce the most desirable response values. These response values may be the maximum yield or the highest level of quality coming off the production line. Similarly, we may seek the variables settings that minimize the cost of making the product. In any case, the set of values of the input variables which result in the most desirable response values is called the set of optimum conditions.
