This paper advances a linear regression forecasting model of multilevel Fuzzy factors. It gives the definition of Fuzzy factor with an evaluation set as uniyersal field, the influence vector of evaluation set, the influence expectation of Fuzzy factor, on the basis of Fuzzy comprenensive evaluation. It also proposes a mathematical model to solve this problem.
In this paper, we have used multilevel Fuzzy synthetic judgement to evaluate effects of tumor vaccine in the immuno-biological therapeutics against tumors. This method is not only objective but also reliable. Therefore, the multilevel Fuzzy synthetic judgement offers a better mathematical model for judging the therapeutic effectiveness of diverse tumor vaccines .
By theory of Fuzzy, M (·, ⊙)operator and comprehensively judging models on Fuzzy of multigradations,we have studied the evaluation methods on resources of travelling climate,in addition,we have made an initial evaluation of Fuzzy on resources of travelling climate of Tai Bai Mountain .
A Model of Estimation and Optimization of Expenditures in Multilevel Fuzzy Environments
Multilevel fuzzy relational systems: structure and identification
Furthermore, this paper gives a similarity measure to improve the evaluation method of WFPRs and the multilevel fuzzy reasoning in which the consequences and their certainty factors are deduced synchronously by using a GFPN.
