Kazemi Department of Mathematics, University of Mohaghegh Ardabili adelpkazemi@yahoo.com For every positive integer k, a set S of vertices in a graph G = (V;E) is a k- tuple dominating set of G if every vertex of V -S is adjacent to at least k vertices and every vertex of S is adjacent to at least k - 1 vertices in S. The minimum cardinality of a k-tuple dominating set of G is the k-tuple domination number of G. When k = 1, a k-tuple domination number is the well-studied domination number. We define the k-tuple domatic number of G as the largest number of sets in a partition of V into k-tuple dominating sets. Recall that when k = 1, a k-tuple domatic number is the well-studied domatic number. In this work, we derive basic properties and bounds for the k-tuple domatic number. k-tuple dominating set,k-tuple domination number,k- tuple domatic number http://cjms.journals.umz.ac.ir/article_450.html http://cjms.journals.umz.ac.ir/article_450_376603f729effe72173d9d24b2684890.pdf

University of Mazandaran Caspian Journal of Mathematical Sciences (CJMS) 1735-0611 2 2 2014 12 31 Some new results on semi fully fuzzy linear programming problems 137 146 EN S.H. Nasseri Department of Mathematics, University of Mazandaran, Babolsar, Iran nasseri@umz.ac.ir R. Chameh Department of Mathematics, University of Mazandaran, Babolsar, Iran E. Behmanesh Department of Mathematics, University of Mazandaran, Babolsar, Iran There are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. The first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. The second method, named as fuzzy dual simplex method, assumes an initial dual basic feasible solution is at hand. In this paper, the shortcomings of these methods are pointed out and to overcome these shortcomings, a new method is proposed to determine the fuzzy optimal solution of such fuzzy problems. The advantages of the proposed method over existing methods are discussed. To illustrate the proposed method a numerical example is solved by using the proposed method and the obtained results are discussed.
