"D numbers theory" is a generalization of Dempster-Shafer theory by Deng & Deng (2014) [Attached file]. I have problems with application of this theory (specifically in its calculations).
This is a good question.
A complete introduction to D number theory is given in a paper where Yong Deng is one of the authors:

Dear Dr. Mohsen Mazaheri Asad,
D numbers are nothing but researchers, thought. I may add like this that after educating ourselves with multi-valued signal and GF(2**n) the modeling of systems with complex uncertainties are possible.
Thanks very much your interest on D numbers. Actually, it is proposed as a generalization of Dempster -Shafer theory which is limited by some strong constrains. The very recent advance on D numbers are there(http://www.mdpi.com/1424-8220/17/9/2086 Fuzzy Risk Evaluation in Failure Mode and Effects Analysis Using a D Numbers Based Multi-Sensor Information Fusion Method; http://ieeexplore.ieee.org/document/8009696/ Exploring the combination rules of D numbers from a perspective of conflict redistribution). In the papers, a new combination rule has been proposed, and the calculations are explained clearly. In the next few days, a new work about D numbers theory will be released. Hope it could benefit your research. Best regards, Xinyang.
Dear Xinyang Deng,
Thank you for your comments and papers you introduced. I'm sure they will be helpful.
Dear professor Xinyang Deng,
I have the similar problem regarding the combination rule of the two D numbers. Can you explain the steps with the help of following example.
Example 4 (Deng et al. 2014)
D1 = {(0,0.7), (1,0.3)}
D2= {(0,0.6), (1,0.4)}
The combination of D1 and D2 using the above equations
D= {(0.0,0.325), (0.5,0.50), (1,0.175)}

Thank you
D numbers theory is an generalization of Dempster-Shafer theory,
which inherits the advantage of Dempster-Shafer theory and strengthens its
capability of uncertainty modelling.
