【摘要】:本文對(duì)李粉香[1]提出特殊雙險(xiǎn)種風(fēng)險(xiǎn)模型進(jìn)行了推廣,從而給出了同保費(fèi)和理賠的到達(dá)過(guò)程為二項(xiàng)過(guò)程的特殊風(fēng)險(xiǎn)模型,即常利率復(fù)合二項(xiàng)雙險(xiǎn)種風(fēng)險(xiǎn)模型,使風(fēng)險(xiǎn)模型更全面科學(xué)的為保險(xiǎn)實(shí)務(wù)服務(wù).全文具體內(nèi)容分為以下幾部分: 第一部分,研究常利息下的復(fù)合二項(xiàng)雙險(xiǎn)種風(fēng)險(xiǎn)模型的破產(chǎn)概率問(wèn)題,首先得出該模型下保險(xiǎn)公司穩(wěn)定經(jīng)營(yíng)的必要條件;其次證明調(diào)節(jié)系數(shù)是存在的,并采用遞歸的方法,得出該模型的兩種破產(chǎn)概率上界的估計(jì). 第二部分,研究此模型的破產(chǎn)概率和生存概率兩種精算指標(biāo),并得到有限時(shí)間內(nèi)的破產(chǎn)概率、最終破產(chǎn)和生存概率的具體分布. 第三部分,,研究此模型在各種精算量的具體分布下調(diào)節(jié)系數(shù)所滿足的方程.利用MATLAB軟件,研究利率因素對(duì)破產(chǎn)概率的影響,并結(jié)合具體實(shí)例進(jìn)行數(shù)值模擬. 第四部分,對(duì)該論文做出總結(jié),并提出我們需要繼續(xù)進(jìn)一步開展的工作.
[Abstract]:A study on the effect of Prunus chinensis. [1. The special double insurance risk model is generalized, and a special risk model is given in which the arrival process of the same premium and claim is binomial, that is, the constant interest rate compound binomial double insurance risk model. Make the risk model more comprehensive and scientific for insurance practice. The full text is divided into the following parts: In the first part, we study the ruin probability of the compound binomial insurance risk model under constant interest, and obtain the necessary conditions for the stable operation of the insurance company under the model. Secondly, it is proved that the adjustment coefficient exists, and the two upper bounds of ruin probability of the model are estimated by recursive method. In the second part, we study the ruin probability and the survival probability of the model, and obtain the ruin probability, the final ruin probability and the survival probability distribution in finite time. In the third part, we study the equation of the adjustment coefficient under the specific distribution of various actuarial quantities. Using MATLAB software, we study the influence of interest rate factors on the ruin probability. Numerical simulation is carried out with concrete examples. Part 4th summarizes this paper and points out that we need further work.
