In real option pricing, it is impractical to assume the present value of expected cash flow payoff as an exact number because it is a forecast one. Generally, the number is regarded as a triangular or trapezoidal fuzzy number to give its estimated interval values and the Black-Scholes (abbreviated as B-S) formula is used to price the real option.

针对实物期权定价中预期现金流收益的现值是个预测值，而采用精确值给出不太合理的问题，分析了三角模糊数或梯形模糊数给出它的区间估计值，并利用Black-Scholes公式为之定价的方法。

A new pricing approach to real option is thus proposed to transform the forecast intervals evaluated by experts into some normal fuzzy numbers with the lattice closeness degree introduced to construct weighted vectors. In this way the rationality of estimating the present value of expected cash flow payoff by using a normal fuzzy number is verified.

提出了将预期现金流收益现值的专家评估区间转化成正态模糊数并利用格贴近度构造权向量的一种新的实物期权定价方法，验证了利用正态模糊数估计现金流收益现值的合理性。
