摘要
In the application of mixture experiments, it's hard to model the outputs with the form of persons' description words mathematically. This paper models the outputs by fuzzy numbers and proposes a mixture model for such kind responses. The parameters of the proposed model are estimated by iterative least square method, and the goodness of fit of the model is evaluated by the average closeness degree. Finally, the procedure is illustrated by an example.
