1. Improving the Reliability of Case-Based Reasoning Systems

Xu Xu, Ke Wang, Weimin Ma, Jie Lin
Pages: 256 - 265
Case-based reasoning (CBR) infers a solution to a new problem by searching a collection of previously solved problems for cases which are similar to the new problem. The collection of previous problems and their associated solutions represents the CBR system’s realm of expertise. A CBR system helps...

2. Reliability Growth Predication based on an Improved Grey Predicton Model

Yuhong Wang, Yaoguo Dang, Sifeng Liu
Pages: 266 - 273
As limits of time, labors and expenses, observed data usually have the characteristic of small sample sizes in development test program. Redesigns or corrective actions can result in changes of reliability for equipments. We propose an improved GM(1,1) model to predict reliability growth in this paper....

3. Improved Fuzzy Art Method for Initializing K-means

Sevinc Ilhan, Nevcihan Duru, Esref Adali
Pages: 274 - 279
The K-means algorithm is quite sensitive to the cluster centers selected initially and can perform different clusterings depending on these initialization conditions. Within the scope of this study, a new method based on the Fuzzy ART algorithm which is called Improved Fuzzy ART (IFART) is used in the...

4. A Lexicographic Method for Matrix Games with Payoffs of Triangular Intuitionistic Fuzzy Numbers

Jiang-Xia Nan, Deng-Feng Li, Mao-Jun Zhang
Pages: 280 - 289
The intuitionistic fuzzy set (IF-set) has not been applied to matrix game problems yet since it was introduced by K.T.Atanassov. The aim of this paper is to develop a methodology for solving matrix games with payoffs of triangular intuitionistic fuzzy numbers (TIFNs). Firstly the concept of TIFNs and...

5. Multiple Criteria Human Performance Evaluation Using Choquet Integral

Tuncay Gürbüz
Pages: 290 - 300
It is a critical issue for the continuity of an organization to efficiently evaluate the performance of its employees. The evaluation process has to guarantee a sufficient level of objectivity and a limited level of subjectivity in order to answer the employees' expectancies. In this study, a multi-criteria...

6. Multi-attribute Evaluation of Website Quality in E-business Using an Integrated Fuzzy AHPTOPSIS Methodology

Tolga Kaya
Pages: 301 - 314
Success of an e-business company is strongly associated with the relative quality of its website compared to that of its competitors. The purpose of this study is to propose a multi-attribute e-business website quality evaluation methodology based on a modified fuzzy TOPSIS approach. In the proposed...

7. Models for Multiple Attribute Group Decision Making with 2-Tuple Linguistic Assessment Information

Guiwu Wei, Xiaofei Zhao, Hongjun Wang, Rui Lin
Pages: 315 - 324
The aim of this paper is to investigate the multiple attribute group decision making(MAGDM) problems with 2-tuple linguistic assessment information, in which the information about attribute weights is incompletely known, and the attribute values take the form of linguistic assessment information. In...

8. Integrated total cost and Tolerance Optimization with Genetic Algorithm

R.Sampath Kumar, N. Alagumurthi
Pages: 325 - 333
The tolerance allocation problem has been studied in the literature for decades, usually using mathematical programming (or) heuristic optimization approaches. Elegant tools for minimum cost tolerance allocation have been developed over several decades but still there is no specified tool to find the...

9. Fuzzy Classifier Design using Modified Genetic Algorithm

P.Ganesh Kumar
Pages: 334 - 342
Development of fuzzy if- then rules and formation of membership functions are the important consideration in designing a fuzzy classifier system. This paper presents a Modified Genetic Algorithm (ModGA) approach to obtain the optimal rule set and the membership function for a fuzzy classifier. In the...
