英文摘要:
In the study of investment problem, aside from the investment risk the background risk appears. Both the investment risk and the background risk are probabilistically described by random variables. This paper starts from the hypothesis that the two types of risk can be represented both probabilistically (by random variables) and possibilistically (by fuzzy numbers). We will study three models in which the investment risk and the background risk can be: fuzzy numbers, a random variabl-a fuzzy number and a fuzzy number-a random variable. A portfolio problem is formulated for each model and an approximate calculation formula of the optimal solution is proved.

中文摘要:
在投资问题的研究中,除了投资风险外,还出现了背景风险。投资风险和背景风险都用随机变量进行概率描述。本文从假设这两种类型的风险可以用概率(随机变量)和可能性(模糊数)来表示开始。我们将研究三种模型,其中投资风险和背景风险可以是:模糊数、随机变量(模糊数)和模糊数(随机变量)。对每个模型都建立了一个投资组合问题,并证明了最优解的近似计算公式。
