| Abstract: | This paper illustrates the utilization of psychophysical scalingand optimization technology to accomplish two goals. First,by means of ‘goal programming’ the odor scientistcan interrelate chemicals and odor qualities, specify a desiredprofile of odor qualities and determine that combination ofodorants which come as close as possible to generating thatdesired profile. Second, by means of non-linear optimization,the scientist can determine the relation between chemical concentrationsand liking, and furthermore ascertain that combination of chemicalconcentrations which generate maximal liking ratings, subjectto constraints. Constraints include chemical concentrationslying within prespecified limits, and sensory perceptions lyingwithin specific bounds. Mixtures of butyric acid and pulegoneillustrate the approach. |
