Fuzzy Pricing Model Of Life Insurance Products Based On Fuzzy Mathematics Theory

Nowadays,the economic level is constantly improving,and countries have focused their attention on the insurance industry.Among them,life insurance,which is of great interest to most people,has attracted particular attention.In the field of life insurance,the core topic is always about how to reliably and effectively price products.Due to the uncertainty of interest rates in the market,the assumptions of the traditional fixed-rate and stochastic interest rate models are too idealistic to reflect the market.Therefore,fuzzy mathematics theory that can effectively balance all aspects of information is introduced to conduct interest rate estimation and life insurance actuarial calculation.Because the estimated interest rate result can be a certain value,it can be a range,or it can be a fuzzy number.Compared with the traditional method of determining the interest rate,it can effectively avoid the uncertainty caused by the lack of market information and influencing factors.risk.In real life,the interest rates in each life insurance policy issued by the insurer are constantly changing with the changes in the market.It is precisely because of the uncertainty of interest rates that the various claims costs on the policy also bear the corresponding interest rates.Risks,these all bring difficulties to life insurance actuarial.This paper proposes to explore the improvement direction of interest rate estimation by means of linear regression,and estimate the fuzzy interest rate and apply it to life insurance actuarial.The life insurance actuarial analysis under the fuzzy interest rate can better meet the actual needs of the insurer.The first is to construct a model of pure premiums under the fuzzy interest rate.The second is to construct a life insurance actuarial model under the fuzzy interest rate.The third is to numerically analyze the fuzzy interest rate,and give the application of the life insurance actuarial model under fuzzy interest rate in real value,and obtain the important role of the parameter ?^* in the fuzzy model in the decision of the insurer.
