It is well known that fuzzy measure and fuzzy integral theory,as an important branch of fuzzy analysis has been investigated and applied widely in other fields Stochastic integral,as a significant component of stochastic analysis,is extensively used in the fields of stochastic control and mathematical finance.Aumann is an easy way to define and study the It? integral of set-valued random variables(even fuzzy random variables).So the Aumann-It? integral of set-value random variables or fuzzy value random variables has been researched,but it is not convenient to calculate the Aumann-It? integral of fuzzy value random variables.We note that in the classical real analysis,the method of Riemann has a distinctive advantage in integral numerical calculation.Henstock integral,as a generalization of Riemann integral,can well deal with the integral of some“highly oscillating”functions,e-specially the numerical calculation.This paper tries to define and discuss the It? integral of set-valued functions(even fuzzy-number-valued functions)by means of the method of Riemann.We summarize the main results of the paper as followsFirst of all,based on It?-Henstock integral and It?-McShane integrals for a adapted real-valued stochastic process with respect to a Brownian motion,combining the integrability of the adapted fuzzy stochastic process with respect to a Brownian motion,the fuzzy It?-Henstock integral and the fuzzy It?-McShane integrals for adapted fuzzy stochastic process with respect to a Brownian motion are defined and their properties are discussed in detail.In addition,some examples are given to illustrate the propertiesThen,the interrelation of the fuzzy It?-Henstock integral and the fuzzy It?-McShane integral is discussed.The result shows that the fuzzy It?-Henstock integral is equivalent to the fuzzy It?-McShane integral when its primitive of fuzzy It?-Henstock integral is It? absolutely continuousFinally,considering that the fuzzy It?-Henstock integral and the fuzzy It?-McShane integral are characterized by Riemann type,the advantage of which is numerical calculation of the fuzzy stochastic process It? integral.With the modu-lus of oscillatory of the fuzzy-number-value functions,the quadrature rules of the fuzzy It?-Henstock integral are discussed and three quadrature rules,such as the It? midpoint-type rule,It? trapezoidal-type rule,It? Simpson's rule and ?-fine delay quadrature rule of the It? integral are given. |
