In 2001, Hainan Sugarcane Breeding Farm bred identified as BC1 hybrid strains of Erianthus real sugar cane for the first time. Fuzzy comprehensive evaluation method in Reference [1] studied and analyzed two strains of sugar cane major economic traits of Erianthus hybrids BC1 17 to have determined it is the fine lines. Fuzzy comprehensive evaluation method, mainly relying on fuzzy matrix, has a ...

A generic format for adaptive vague logics is presented. The concrete adaptive vague logics based on this format are able to (1) identify sentences as vague or non-vague in the context of a given set of premisses, and to (2) dynamically adjust the possible set of inferences in accordance with these identifications, i.e. vague sentences can only make use of vague inference rules, sentences conte...

Inaccessibility of part of the database is a research topic hardly addressed in the literature about distributed databases. However, there are various application areas, where the database has to remain operable even if part of the database is inaccessible. In particular, queries to the database should be processed in an appropriate way. This means that the nal and all intermediate results of a...

College of science and engineering, College of electronic information engineering, Qiongzhou University, Sanya Hainan 572022, China. [email protected], [email protected] Abstract. The Vague optimization method sorted out is a special case of the pattern recognition method of the Vague set. Its specific application steps are as follows: ○1the set-up of characters to determine the evaluation; ○2th...

Here a novel idea to handle imprecise or vague set viz. Pseudo fuzzy set has been proposed. Pseudo fuzzy set is a triplet of element and its two membership functions. Both the membership functions may or may not be dependent. The hypothesis is that every positive sense has some negative sense. So, one membership function has been considered as positive and another as negative. Considering this ...

In many online shopping applications, such as Amazon and eBay, traditional Association Rule (AR) mining has limitations as it only deals with the items that are sold but ignores the items that are almost sold (for example, those items that are put into the basket but not checked out). We say that those almost sold items carry hesitation information, since customers are hesitating to buy them. T...

The complexities of modeling uncertain data in economics, engineering, environmental science, sociology, medical science and many other fields can not be successfully dealt with by classical methods. While probability theory, fuzzy set theory,rough set theory, vague set theory and the interval mathematics are useful approaches to describing uncertainty, each of these theories has its inherent d...

Reliability modeling is the most important discipline of reliable engineering. A new method for analyzing fuzzy system reliability using vague set theory is demonstrated, where the reliabilities of the components of a system are represented by vague sets defined in the universe of discourse [0, 1]. The proposed method can model and analyze the fuzzy system reliability in a more flexible and mor...

One important characteristic of distributed database management systems (DBMS) is that due to network or machine failure the environment may become partitioned into sub-environments that cannot communicate with each other. However, there are various application areas where the individual sub-environments should remain operable even in such situations [2, 5]. In particular queries to the databas...

The notion of fuzzy function based on many-valued equivalence relations (many-valued similarity relations (equalities) [17, 18, 19], fuzzy equivalence relations [4, 6, 7, 21, 22, 26], similarity relations [1, 2, 3, 15, 28], indistinguishability operators [27], etc.) has been introduced by several authors, and applied to category theory [5], approximate reasoning and fuzzy control theory [8, 10,...
