The Life Insurance Model under Fuzzy Rates of Interest

摘要

In this paper, some basic concepts of uncertainty theory are introduced and arithmetic of the trapezoidal fuzzy variable are discussed. Next, we establish the discrete-life-insurance model with the uncertain interest rates which is descripted by the trapezoidal fuzzy variable, moreover, the formulas of level-net-premium and reserve are gained. At last, an example is presented to illustrate the application of the model.
