A Novel Failure Mode and Effects Analysis Model Using Triangular Distribution-Based Basic Probability Assignment in the Evidence Theory

IEEE Access, 2020
Failure mode and effects analysis (FMEA) is a typical risk assessment and prevention technology, in which different experts provide different assessments on the target system to identify the risk grades of its components.

A Note on Probability /Possibility Consistency for Fuzzy Events [PDF]

, 1996
It is noted that the standard t-norm definitions of conditional probability of fuzzy events are probability / possibility inconsistent. Two alternative definitions are proposed and their consistency with two definitions of the possibilityof fuzzy events ...

Determining Basic Probability Assignment Based on the Improved Similarity Measures of Generalized Fuzzy Numbers [PDF]

, 2015
Dempster-Shafer theory of evidence has been widely used in many data fusion application systems. However, how to determine basic probability assignment, which is the main and the first step in evidence theory, is still an open issue.

A Multishift Hessenberg Method for Pole Assignment of Single-Input Systems [PDF]

, 1996
A new algorithm is proposed for the pole assignment of single-input linear time-invariant systems. The proposed algorithm belongs to the family of Hessenberg methods and is based on an implicit multishift QR-like technique.

Pignistic Belief Transform: A New Method of Conflict Measurement

IEEE Access, 2020
To measure conflict between two basic probability assignment functions plays the key role of conflict management in Dempster-shafer evidence theory. In this paper, a new conflict measure is proposed.

Estimation of treatment effects in observational studies by recovering the assignment probabilities and the population model

, 2007
In observational studies the assignment of units to treatments is with unknown probabilities. Consequently, estimation and comparison of treatment effects based on the empirical distributions of the response under the various treatments can be biased ...
