Application of fuzzy cognitive maps to factors affecting slurry rheology

We propose fuzzy cognitive maps, a branch of fuzzy logic, to study interaction of factors affecting processes and details of the approach are discussed. Application of the technique to discriminate between factors affecting slurry rheology is demonstrated. It has been shown that hydrodynamic interaction, effective particle concentration, shape and size, temperature and shear rate have a significant influence on the slurry viscosity. The complex interaction of the various factors delineated by previous workers is also presented

An Approach to Hotel Services Dynamic Pricing Based on the Delphi Method and Fuzzy Cognitive Maps

Part 12: First Workshop on Fuzzy Cognitive Maps Theory and Applications (FCMTA 2013)International audienceE-tourism services open up new opportunities for businesses to expand and when possible to gain completive advantage. Dynamic pricing is an area of interest for both researchers and professionals. It’s the process of price specification in a way that best suits a tourism organization under certain circumstances that reflect its competitive environment. Many research studies have addressed dynamic pricing from different perspectives. This study suggests that the use of a hybrid approach that combines Delphi method and fuzzy cognitive maps is suitable for it introduces fuzzy logic in order to capture the subjectivity and vagueness involved into evaluating the business settings, but it also provides for the necessary flexibility in analyzing the assumptions and the implications of different pricing scenarios
