Acceptance Double Sampling Plan with Fuzzy Parameter
Ezzatallah Baloui Jamkhaneh, Bahram Sadeghpour-Gildeh, Gholamhossein Yari
In the present paper we have proposed a method for designing acceptance double sampling plans with fuzzy quality characteristic. we have argued the acceptance double sampling plan when the fraction of defective items is a fuzzy number. These plans are well defined since if the fraction of defective items...

Toolbox for Interval Type-2 Fuzzy Logic Systems
Mohsen Zamani, Hossein Nejati, Amin T. Jahromi, AliReza Partovi, Sadegh H. Nobari, Ghasem N. Shirazi
Type-2 systems has been becoming the focus of research in the field of fuzzy logic in recent years. Comparing with type-1 systems, type-2 fuzzy systems are more complex and relatively more difficult to understand and implement. We developed an interactive graphical user interface (GUI) based toolbox,...

Optimism and Pessimism in Decision Making Based on Intuitionistic Fuzzy Sets
Ting-Yu Chen, Che-Wei Tsui
This paper presents a method of relat-ing optimism and pessimism to multiple criteria decision analysis based on intuitionistic fuzzy sets. We develop the concepts of optimistic and pessimistic point operators to measure optimism and pessimism, respectively. Furthermore, we provide an approach to effectively...

A Comparative Study of Intuitionistic Fuzzy Entropy on Attribute Importance
Ting-Yu Chen, Chia-Hang Li, Che-Wei Tsui
We propose a new objective weight method by using intuitionistic fuzzy (IF) entropy measures for multiple attribute decision making (MADM). We utilize the nature of IF entropy to assess the attribute weight based on the credibility of data, and the concept is totally different with the traditional one....

Personalized Advertisement System Based On Computational Intelligence
Kemal Kilic
A software company develops an online socialization platform where users inter-act with others at virtual environments. The company’s income is from the adver-tisements displayed at these virtual envi-ronments. They are willing to develop a personalized advertisement system in or-der to increase their...

Key Risk Factors Assessment for Metropolitan Underground Project
Shih-Tong Lu, Cheng-Wei Lin, Hsin-Lung Liu
Underground construction project in metropolis is more dynamic and risky. A key risk factors analysis will give project contractor a more rational basis on which to make decision. This study applies the fuzzy preference relations to deal with the degree of impact and rank for the main risk factors of...

Clustering Blog Information
Mayank Prakash Jaiswal, H. Chris Tseng
Blogs form an important source of information in today’s internet world. Most of the blog websites have the blogs arranged in chronological order rather than its con-tents. Such arrangement of blogs makes it difficult for the user searching information about a particular topic from the blog. To resolve...

Demonstration of Learned Helplessness with Fuzzy Reinforcement Learning
Vali Derhami, Zahra Youhannaei
This paper demonstrates a kind of learned helplessness in human being that is ap-peared in Fuzzy Reinforcement Learning (FRL) algorithm. At the beginning of learning, when an agent continuously per-forms actions that cause sequential pun-ishments, afterwards it does not usually behave well and...

Similarity Based Fuzzy and Possibilistic c-means Algorithm
Chunhui Zhang, Yiming Zhou, Trevor Martin
A similarity based fuzzy and possibilistic c-means algorithm called SFPCM is presented in this paper. It is derived from original fuzzy and possibilistic c-means algorithm(FPCM) which was proposed by Bezdek. The difference between the two algorithms is that the proposed SFPCM algorithm processes relational...

Toward A Measurement Model of Fuzzy Prioritization Operators
K.K.F. YUEN
The Fuzzy Prioritization Operators (FPOs) have been studied by various studies. As various FPOs produce different results, the fitness levels of FPOs are necessary to be measured. This research reviews two important FPOs, and proposes a Fuzzy Prioritization Measurement (FPM) model to measure the appropriateness...

Type-2 Fuzzy Classifier Ensembles for Text Entailment
Asli Celikyilmaz, I. Burhan Turksen
This paper presents a new Type-2 Fuzzy Classifier ensemble, which enables to model parameter uncertainties by charac-terizing the fuzzy sets with secondary membership values. We use fuzzy clus-tering method to characterize primary membership values and genetic algorithm to approximate secondary membership...

Application of Sensitivity Analysis, “Worst Case”, and Maximum Possible Risk (MPR) to Adventitious Events
T. Taylor, T. Whalen, M. Cohen
We present here a logical progression of probability and risk analysis for adventi-tious events, events whose probability is not well measurably different from zero (WMDZ). We will show that such analy-ses culminate in maximum possible risk (MPR) and, further, that MPR is equiva-lent to a boundary condition...

Explicit Spatial-Temporal Simulation of a Rare Disease
Ling Bian, T Whalen, M Cohen, Y. Huang, G. Lee, E. Lim, L. Mao, Y. Yan
This paper reports on the use of possibility theory and agent based explicit spatio-temporal simulation to compare the effects on each of three real communities given the assumption that a rare disease is carried out of a hypothetical high containment biological research laboratory sited in that community....

Issues in Microbial Risk Assessment
M. Cohen, T. Taylor, Jr. T. Whalen
Microbial risk assessment is the quantita-tive (or qualitative) characterization of the potential health effects of a particular mi-croorganism on individuals or populations. Practical public health policy/decisions to-day requires rethinking traditional ap-proaches in how microbial risk assessments...

Maximum Possible Risk Modeling
M. Schütz, M. Cohen, T. Whalen, T. Taylor
Counterfactual assumptions enable a maximum possible risk analysis of the possibility of an aerosol release of pathogens such as anthrax spores from a biological research laboratory. Eight counter-factual assumptions in conjunction ensure that any actual laboratory accident would pose a risk of exposure...

Possibilistic Risk and Counterfactual Probabilities
T. Whalen, T. Taylor, M. Cohen
Possibility theory is applied to assessing the relative risk associated with very rare, high-consequence hazards. The probability of rare negative events has to be estimated from a few past occurrences that are spread over long exposure periods, with counter- measures added in response to each event...
