A framework for a multi-attribute multi-source data fusion is described. Uncertainty of data is modeled by fuzzy sets. The problem is considered on a general level. Credibility of sources, compatibility of data, as well as their reasonableness, are taken into consideration. The proposed method is illustrated by an example.

Three definitions of fuzzy random variables (FRVs) have been cited in the current literature: the first is due to Kwakernaak (1978), who viewed a FRV as a vague perception of a crisp but unobservable RV; the second is due to Puri and Ralescu (1986), who regarded FRVs as random fuzzy sets; and the third is due to Liu and Liu (2003), whose notion of FRV was based on a concept they called a credib...

In response to changeful financial markets and investor’s capital, we discuss a portfolio adjusting problem with additional risk assets and a riskless asset based on credibility theory. We propose two credibilistic mean–variance portfolio adjusting models with general fuzzy returns, which take lending, borrowing, transaction cost, additional risk assets and capital into consideration in portfol...

Economic theory predicts a positive relationship between property rights and economic growth. However, few developing countries have experienced better economic performance after improving their protection of property rights. The following manuscript addresses this puzzle by directly assessing where property rights reforms have been effective. I argue that multiple, reinforcing credibility mech...

Microblogs have become an increasingly important source of information, both in the U.S. (Twitter) and in China (Weibo). However, the brevity of microblog updates, combined with increasing access of microblog content through search rather than through direct network connections, makes it challenging to assess the credibility of news relayed in this manner [34]. This paper reports on experimenta...

A declarative programming language has two kinds of semantics The more abstract helps in reasoning about speci cations and correctness while an operational semantics determines the manner of program exe cution A correct program should reconcile its abstract meaning with its concrete interpretation To help in this we present a kind of algebraic semantics for logic pro gramming It lists only thos...

The failure possibility of transmission lines in power system may change from time to time since it will be affected by weather, environment and operating conditions, especially under short-time period. Impacts of various conditions on failure possibility can be described using fuzzy words. In this paper, credibility theory was introduced to model the short-term line maintenance-scheduling prob...
