Some Fuzzy Logic --Dickeson

Personalized Ratios

Whatever YOUR ratio turns out to be, it's the one to use. It represents what you've been getting for all the jobs you've manufactured during the period you selected. Use that ratio as a divisor. Divide the DOAs for any job by the ratio. There's the average price you'd charge for such a job. But you want to "adjust" it to fit the circumstances, don't you? Aha! It's in the adjusting process that we leave crisp values and suddenly get fuzzy.
