Assessment of reliability analysis of paper plant with fuzzy logic technique has carried out in this paper. Fuzzy Weibull distribution and lifetime of a component is also determined. The paper plant is a complex system under consideration which consists of various subsystems such as chipping, feeding, pulp preparation, washing, screening, bleaching and paper production etc. The mathematical mod...

Early detection of breast cancer is the key to improve survival rate. Thermogram is a promising front-line screening tool as it is able to warn women of breast cancer up to 10 years in advance. However, analysis and interpretation of thermogram are heavily dependent on the analysts, which may be inconsistent and error-prone. In order to boost the accuracy of preliminary screening using thermogr...

The fuzzy sets possess natural capability to capture measurement uncertainty as a part of experimental data. Therefore the uncertainties of various kinds involved in system failure analysis may be adequately addressed using the concept of fuzzy sets. Fonseca et al developed and implemented fuzzy reasoning algorithm via an expert system to assess the likelihood of equipment failure mode. The alg...

the comprehensive assessment model considers the financial and non-financial aspects as balanced scorecard. also, for more comprehensive results of the investigation, four aspects of the balanced scorecard were used and then by using fuzzy delphi technique and experts' opinions, the standard aspects of each were achieved in two stages. to determine the importance of each aspect of bsc, the proce...

Yager introduced a fuzzy screening procedure to select, from a large class of alternatives, a small subset to be further investigated. In his methodology the Kleene-Dienes implication operator was employed to find the unit score of each alternative by each expert. Generalizing Yager’s principle we suggest the use of Sand R-implication operators to find the unit score.

Modeling the suitability of land to support specific land uses is an important and common GIS application. Three classic models, specifically pass/ fail screening, graduated screening and weighted linear combination, are examined within a more general framework defined by fuzzy logic theory. The rationale underlying each model is explained using the concepts of fuzzy intersections, fuzzy unions...

the purpose of this study is identification and barrier analysis for green supply chain management implementation in sirjan's golgohar using fuzzy topsis technique and fuzzy dematel technique. at first, in this study barriers for green supply chain management are identified through literature and survey with experts and the priority processing is doing with fuzzy topsis technique. this study is...

Exudates are the primary signs of diabetic retinopathy which are mainly cause of blindness. It could be prevented with an early screening process. Pupil dilation is required in the normal screening process but this affects patients’ vision. Automatic computerized screening should facilitate screening process, reduce inspection time and increase accuracy. In this paper we proposed an automatic m...

This paper considers a probabilistic inventory model with uniform leadtime demand and fuzzy cost components under probabilistic and imprecise constraints. Firstly we solve the model by general fuzzy non-linear programming technique. Then intuitionistic fuzzy optimization technique is applied and finally, regarding the optimization of the objective function a comparative study is presented among...
