Abstract:

In this paper, the uncertainty of the multidimensional European maximal call option is characterized by a combination of fuzziness and stochasticity. The pricing formulas for the correspond-ing European maximal call option are given by L$\acute{\rm e}$vy-It$\hat{\rm o}$ formula, when the logarithm of the jump amplitude is with fuzzy normal sum and fuzzy double exponential distribution. A clarity number is given by weighted probability averaging in the valuation of the fuzzy option. Finally, the effects of the variation of the main parameters and different models on the pricing of the European maximal call option are analyzed by numerical simulation.

Key words: fuzzy random variables, fuzzy Lognormal distribution, fuzzy double exponential distribution, European maximal call option
