Fuzzy Value Function's Curvilinear and Surface Integral Base on Fuzzy Structured Element Method (Ⅰ ) -Fuzzy-valued Function's Curvilinear Integral

摘要

According to the fuzzy structured element representation theorem of fuzzy-valued function, under the background of engineering, this paper gives the definition of fuzzy-valued function's first form curvilinear integral, presents the representation theorem of two-dimensional fuzzy number and fuzzy vector based on fuzzy structured element, and gives the definition of the fuzzy-valued function's second form curvilinear integral. In fact, both calculation method and property of fuzzy-valued function's curvilinear integral have been presented in this paper.
