One-dimensional cutting stock problem with divisible items: a case study in steel industry
(Işık University Press, 2019)This paper considers the one-dimensional cutting stock problem (1D-CSP) with divisible items, which arises in the steel industries. While planning the steel cutting operations, each item can be divided into smaller pieces, ... -
Exponential domination of tree related graphs
(Işık University Press, 2019)The well-known concept of domination in graphs is a good tool for analyzing situations that can be modeled by networks. Although a vertex in the graph can exert influence on, or dominate, all vertices in its immediate ... -
On some properties of normal ?-ideals in normal ?-semigroups
(Işık University Press, 2019)We introduce the concept of normal ?-ideal and bi-?-ideal in normal ?semigroups. We characterize the (normal) ?-semigroup and normal regular ?-semigroup in terms of elementary properties of bi-?-ideal proving the various ... -
Numerical solution of time-fractional order Fokker-Planck equation
(Işık University Press, 2019)In this article, new iterative method (NIM) is employed to find the numerical solution of linear and nonlinear time-fractional order Fokker-Planck equation (FPE), which is applied in many fields of engineering and applied ... -
Geometric function optimization subject to mixed fuzzy relation inequality constraints
(Işık University Press, 2019)In this paper, the mixed fuzzy relation geometric programming problem is considered. The Mixed Fuzzy Relation Inequality (MFRI) system is an importance extension of FRI. It is shown that its feasible domain is non-convex ... -
On the partial sums of convex harmonic univalent functions
(Işık University Press, 2019)Partial sums of analytic univalent functions and partial sums of starlike have been investigated extensively by several researchers. In this paper, we investigate a partial sums of convex harmonic functions that are univalent ... -
Zagreb indices and multiplicative Zagreb indices of double graphs of subdivision graphs
(Işık University Press, 2019)Let G be a simple graph. The subdivision graph and the double graph are the graphs obtained from a given graph G which have several properties related to the properties of G. In this paper, the first and second Zagreb and ... -
Boundedly solvability of first order delay differential operators with piecewise constant arguments
(Işık University Press, 2019)Using the methods of operator theory, we investigate all boundedly solvable extensions of a minimal operator generated by first order delay differential-operator expression with piecewise constant argument in the Hilbert ... -
Harmonious coloring of multicopy of complete graphs
(Işık University Press, 2019)In this paper, we find the harmonious chromatic number of multicopy of complete graphs Kn. We generalize the result ?H ((n + 2)Kn) > n + 1 2 ! given in [8] and also further improve the result to ?H((n + 2)Kn) ? n + 1 2 ! ... -
On a distribution of the process describing a service system with unreliable devices
(Işık University Press, 2019)In the paper, the distribution is found for the process {?t, ?t}, t ? 0, in the terms of Laplace transformation. The considered process describes the queuing system with nonhomogeneous Poisson stream of demands and n ... -

Measurement of planarity in product bipolar fuzzy graphs
(Işık University Press, 2019)Bipolar fuzzy set theory provides a basis for bipolar cognitive modeling and multiagent decision analysis, where in some situations, the product operator may be preferred to the min operator, from theoretical and experimental ... -
An algorithmic approach to equitable edge chromatic number of graphs
(Işık University Press, 2019)The equitable edge chromatic number is the minimum number of colors required to color the edges of graph G, for which G has a proper edge coloring and if the number of edges in any two color classes differ by at most one. ... -
Vulnerability in networks
(Işık University Press, 2019)Recently defined exponential domination number is reported as a new measure to graph vulnerability. It is a methodology, emerged in graph theory, for vulnerability analysis of networks. Also, it gives more sensitive results ... -

Chromatic weak domatic partition in graphs
(Işık University Press, 2019)In a simple graph G, a subset D of V (G) is called a chromatic weak dominating set if D is a weak dominating set and χ(< D >) = χ(G). Similar to domatic partition, chromatic weak domatic partition can be defined. The maximum ...
