Solution of Fuzzy Initial Value Problems Using Homotopy Analysis Method and Padè Approximate

Rana H. Ali, Kais I. Ibraheem
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...

On Analysis of Tangshan Pre-Hospital Service Efficiency Based on Improved Fuzzy-DEA

Qiaozhi Sang, Fengzhu Yao, Shuo Hao, Zhennan Zhang
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

Properties of Fuzzy Length on Fuzzy Set

Jehad R. Kider, Jaafar Imran Mousa
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

On Casaro Sequence Space of Fuzzy Numbers Defined by a Modulus Function

Ayhan Esi, Vakeel A. Khan
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.
