In this paper, we have studied and developed some analytical methods for solving some linear and fuzzy differential equations of the first degree with their fuzzy elementary conditions using the homotopy analytical method, using the approximate Padè method, and comparing the results with the exact solution of the equation, which indicates that the error decreases exponentially with the N degree of approximation. Also, we made some improvements to the solution results by using Padè enhancements a...

An allocation model based on improved Fuzzy-DEA is proposed for Tangshan medical health resource. The membership function is particularly introduced to characterize the non-strict partial order relation of the fuzzy numbers, and the internal form of the unit efficiency values is converted into point values. The variance analysis index system is then used to find factors leading to non-DEA effectiveness and the allocation plan is

The definition of fuzzy
length space on fuzzy set in this research was introduced after the studies and
discussion of many properties of this space were proved,
and then an example to illustrate this notion was given. Also the
definition of fuzzy convergence, fuzzy bounded fuzzy set, and fuzzy dense fuzzy
set space was introduced, and then the definition of fuzzy continuous operator was introd

The main purpose of this paper is to introduce the sequence space cesF(f, p) of sequence of
fuzzy numbers defined by a modulus function. Furthermore, some inclusion theorems
have been discussed.
