The major objective of this paper is to examine the optimal routing in layout and location problems from a network optimization perspective where manufacturing facilities are modelled as open ®nite queueing networks with a multiobjective set of performance measures. The overall material handling system is broken down into a set of layout topologies. For each one of these topologies the optimal ...

in this paper, by presenting some notions and theorems, we obtaindifferent types of fuzzy topologies. in fact, we obtain somelowen-type  and chang-type fuzzy topologies on general fuzzyautomata. to this end, first we define a kuratowski fuzzy interioroperator which induces a  lowen-type  fuzzy topology on the  set ofstates of a max- min general   fuzzy automaton. also by  provingsome theorems, ...

This article attempts to discuss the problems in building new topologies utilizing embedding. We propose to utilize the cartesian product to describe graphs as a right mathematical solution to adjacency matrix. We applied the cartesian product of two and sets of multiple dimensions in analysis. We proposed methodology of building logical topologies based on utilization of regular and symmetric ...

Assume that ? and ? are two independent random variables with distribution functions F? F?, respectively. The of a variable ??, denoted by F??F?, is called the product-convolution F?. It proved F??F? generalized subexponential if belongs to class distributions nonnegative not degenerated at zero.
