A more accurate second-order polynomial metamodel using a pseudo-random number assignment strategy
نویسنده
چکیده
The response surface metamodel is a useful sequential methodology for approximating the relationship between the input variables and the output response in computer simulation. Several strategies have been proposed to increase the accuracy of the estimation of the metamodel. In the current paper, we introduce an effective pseudo-random number (PRN) assignment strategy with Box-Behnken design to construct a more accurate second-order polynomial metamodel to estimate the network reliability of a complex system. The results obtained from the simulation approach show that the reduction in maximum absolute relative error between the response surface approximation and the actual reliability function is 35.63% after the PRN assignment strategy is applied.

A Pseudo-Random Number Assignment Strategy for Simulation Experiments
Simulation models are often used to select alternatives to system designs. A model of a simulation model, referred to as ametamodel, can be used to explore the functional relationships between the mean response of a simulation model and a set of simulation input variables. The estimated metamodel is then used to predict the system response for speci ed sets of input variables and to identify th...
متن کاملOrder Statistics for Probabilistic Graphical Models
We consider the problem of computing r-th order statistics, namely finding an assignment having rank r in a probabilistic graphical model. We show that this problem is NP-hard even when the graphical model has no edges (zero-treewidth models) via a reduction from the number partitioning problem. We use this reduction, specifically pseudopolynomial time algorithms for number partitioning, to yie...

متن کاملDynamic Spectrum Access for Primary Operators Via Carrier Aggregation in LTE-Advanced Environments
In this paper, we address dynamic spectrum access for Primary Operators (POs) for LTEAdvanced systems. We propose a dynamic spectrum access framework that exploits the capabilities of carrier aggregation to efficiently utilize the unutilized spectrum which varies with time and space when static spectrum access policies are adopted. A spectrum owner (SO) adopts an auction scheme for accessing sp...
