摘　　要：假设索赔额、盈余额和更新过程均是在模糊随机环境中,并且将索赔过程定义为在交替更新过程.当索赔额和时间间隔是服从不同的指数分布时,本文建立了交替更新过程下的模糊随机破产模型,并给出了最终破产概率公式与最终破产机会均值公式.The claim amount, the surplus and the renewal process of claim were assumed to be in the fuzzy random environment. The claim process was defined as the alternating renewal process. When the claim amount and the time interval obey different exponential distributions, the fuzzy random ruin model was built under the alternating renewal process, and the ultimate ruin probability formula and mean chance value formula of ultimate ruin were given.
