In recent years, flexible manufacturing system as a response to market demands has been proposed to increase product diversity, optimum utilization of machines andperiods of short-term products.The development of computer systems has provided the ability to build machines with high functionality and the necessary flexibility to perform various operations. However, due to the complexity and the ...

In recent years the difficulties in measurement and prediction of Internet traffic matrices have prompted a number of routing and network design strategies broadly termed “oblivious” [1–3]. They are oblivious in the sense that they guarantee performance under any possible traffic matrix. This appealing property has a cost: extra capacity is needed to ensure that performance is maintained under ...

in zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. the proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be appl...

In this paper, we address the challenge of overlay topology design by considering which overlay topology best minimizes cost function, taking into account overlay link creation cost and routing cost. First, we formulate the problem as Integer Linear Programming (ILP) given a traffic matrix and assuming cooperative behavior of nodes. Then, we propose some heuristics to find near-optimal overlay ...

AbsfrucfThis paper focuses on multicast support in inputqueued packet switches with internal multicast capabilities. Besides providing an overview of some alternative architectures and algorithms proposed in the literature, the paper brings two original contributions. First, multicast traffic admissibility conditions are defined, and theorems showing intrinsic performance losses of input-queued...
