摘要
本文在扎德(L.A.Zadeh)教授的可能性理论的基础上,讨论了可能性线性系统的模型形式,并且在对称模糊数范围内研究了可能性线性系统的辨识问题.可能性线性模型的参数估计问题可以转化为线性规划问题,这类线性规划问题是易解的.
In this paper, the model forms of the possibilistic linear systems are discussed on the basis of professor zadeh's possibility theory,and the identification problem of the possibilistic linear systems is studied in the limits of symmetrical fuzzy numbers.The paramet-ers estimation of the possibilistic linear models can be turned into the linear programming problem, which is easy to solve.
