End Notes

This chapter presents the concept of joint possibility distribution from the point of view of fuzzy number membership. The concept of completely correlated fuzzy numbers is presented. Next, an interactive fuzzy number subtraction operator is discussed. Finally, some bio-mathematical models are presented. The first and second use t-norm concepts. The third study looks of the risk of getting dengue fever from the Takagi-Sugeno inference method. The last bio-mathematical model presented is an epidemiological SI-model with completely correlated initial conditions.
