A Model for Fuzzy Multidimensional Spaces
نویسندگان
چکیده
Fuzzy data representation and manipulation is needed in Data Warehouse due to imprecision or uncertainty from different sources. Nevertheless, this problem has not been wide explored. We propose a fuzzy multidimensional model, cube and operators with a notion of fuzzy hierarchy based on fuzzy functional dependencies.

Fuzzy rule interpolation for multidimensional input spaces in determining d50c of hydrocyclones
Fuzzy rule-based systems have been very popular in many engineering applications. In mineral engineering, fuzzy rules are normally constructed using some fuzzy rule extraction techniques to establish the determination model in predicting the d50c of hydrocyclones. However, when generating fuzzy rules from the available information, it may result in a sparse fuzzy rule base. The use of more than...
متن کاملAPPLICATION OF ADAPTIVE NEURO-FUZZY INFERENCE SYSTEM FOR THE ASSESSMENT OF DAMAGED ZONE AROUND UNDERGROUND SPACES
The development of an excavation damaged zone (EDZ) around an underground excavation can change the physical, mechanical and hydraulic behaviors of the rock mass near an underground space. This might result in endangering safety, achievement of costs and excavation planed. This paper presents an approach to build a prediction model for the assessment of EDZ, based upon rock mass characteristics...
متن کاملMultidimensional fuzzy finite tree automata
This paper introduces the notion of multidimensional fuzzy finite tree automata (MFFTA) and investigates its closure properties from the area of automata and language theory. MFFTA are a superclass of fuzzy tree automata whose behavior is generalized to adapt to multidimensional fuzzy sets. An MFFTA recognizes a multidimensional fuzzy tree language which is a regular tree language so that for e...
متن کاملAn Improved Multidimensional Alpha-cut Based Fuzzy Interpolation Technique
Fuzzy rule based systems have been very popular in many engineering applications. However, when generating fuzzy rules from the available information, it may result in a sparse fuzzy rule base. Fuzzy rule interpolation techniques have been established to solve the problems encountered by sparse rule bases. In most engineering applications, the use of more than one input variable is common. This...
