Powers of the operator u(z)d/dz and their connection with some combinatorial numbers [PDF]

Notes on Number Theory and Discrete Mathematics
In this paper the operator A = u(z)d/dz is considered, where u is an entire or meromorphic function in the complex plane. The expansion of Aᵏ (k≥1) with the help of the powers of the differential operator D=d/dz is obtained, and it is shown that this ...

The Operational Laws of Symmetric Triangular Z-Numbers

Mathematics
To model fuzzy numbers with the confidence degree and better account for information uncertainty, Zadeh came up with the notion of Z-numbers, which can effectively combine the objective information of things with subjective human interpretation of ...

On Generalized Schur Numbers of the Equation x+ay=z

Journal of Mathematics, 2020
Let a and r be positive integers. By definition, sar is the least positive integer such that, for any r-coloring of the interval 1,sar, there exists a monochromatic solution to x+ay=z. For a=1, the numbers sr=s1r are classical Schur numbers.

Ordered discrete and continuous Z-numbers [PDF]

, 2020
Both discrete and continuous Z-numbers are pairs of discrete and continuous fuzzy numbers. Even though the later are ordered, this do not simply imply the discrete and continuous Z-numbers are ordered as well.

Fuzzy Multicriteria Decision-Making Model Based on Z Numbers for the Evaluation of Information Technology for Order Picking in Warehouses

Applied Sciences, 2022
Order-picking process management is one of the most demanding tasks within the operations of a warehouse system. It is especially evident in companies that have a high intensity of product flows, so the question of increasing the productivity of order ...

Z-Number-Based Maximum Expected Linear Programming Model with Applications

Mathematics, 2023
In research of a better description for information uncertainty, Z-numbers, which are related to both the objective information and the subjective criticism, were first conceptualized by Zadeh.

Multi Attribute Decision Making Using Optimistic/Pessimistic Z-Numbers

IEEE Access, 2018
This paper presents a novel approach for multi attribute decision making (MADM). It proposes the concept of optimistic/pessimistic Z-number, which is defined as a tuple (Zx, δ) where Zx is a Z-number, and δ ∈ {+, -} determines if the
