Alternative ruin theory models:barrier stategies, generalized cramér-lundberg model

精算学的一个分支，称为风险理论，分析与保险公司盈余过程的发展有关的重要数量。例如，这些量是破产概率、破产时的赤字和破产前的盈余。这些提供了衡量保险公司整体战略风险的措施。因此，他们提出了提高公司避免破产（或破产）的机会的方法，以及保持有竞争力的保险费率。

One of the branches in actuarial science, called risk theory, analyzes important quantities related to the development of the surplus process of insurance companies. Such quantities are the probability of ruin, the deficit at the time of ruin, and the surplus immediately before ruin, for instance. These provide measures of the riskiness of the overall strategy of an insurance company. As a consequence, they suggest ways of improvement of the company's chances of avoiding insolvency (or ruin), as well as retaining competitive premium rates.
