The finite element method is widely used for solving various problems in geotechnical engineering practice. The input parameters required for the calculations are generally imprecise. The paper is devoted to a comparison of probabilistic, stochastic and fuzzy set method for reliability analysis with respect to its applicability for practical problems in geotechnical engineering. Emphasis will b...

Abstract Reliability allocation is the key issue of reliability designing. CNC machine is a complex product. There are many influence factors of reliability allocation. A part of them cannot be accurately measured but be evaluated by the experts. Therefore it’s difficult for reliability allocation. In this paper, we consider a variety of criteria for conducting reliability allocation. A method ...

This paper proposes an novel maximum power point tracking (MPPT) method for the wind energy conversion system using a Fuzzy with Genetic Algorithm. The proposed output max-imitation control is achieved without mechanical sensors such as the wind speed or position sensor & the new control system will deliver maximum electric power with weightless, high efficiency, and high reliability. The MPPT ...

Uncertainty is inevitable in any reliability analysis of complex engineering systems due to uncertainties present in models, parameters of the model, phenomena and assumptions. Uncertainties at the component level are propagated to quantify uncertainty at the system level reliability. It is very important to identify all the uncertainties and treat them effectively to make reliability studies m...

Based on the basic theory of fuzzy set, this paper suggests the notion of FCM fuzzy set, which is subject to the constraint condition of fuzzy c-means clustering algorithm. The cluster fuzzy degree and the lattice degree of approaching for the FCM fuzzy set are presented, and their functions in the validation process of fuzzy clustering are deeply analyzed. A new cluster validity index is propo...

Problem statement: The work presented Fuzzy Modeled K-means Cluster Quality Mining of hidden knowledge for Decision Support. Based on the number of clusters, number of objects in each cluster and its cohesiveness, precision and recall values, the cluster quality metrics is measured. The fuzzy k-means is adapted approach by using heuristic method which iterates the cluster to form an efficient v...
