monte carlo simulation to compare markovian and neural network models for reliability assessment in multiple agv manufacturing system
Authors
abstract
we compare two approaches for a markovian model in flexible manufacturing systems (fmss) using monte carlo simulation. the model which is a development of fazlollahtabar and saidi-mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (agv) namely, the reliability of machines and the reliability of agvs in a multiple agv jobshop manufacturing system. the current methods for modeling reliability of a system involve determination of system state probabilities and transition states. since, the failure of the machines and agvs could be considered in different states, therefore a markovian model is proposed for reliability assessment. the traditional markovian computation is compared with a neural network methodology. monte carlo simulation has verified the neural network method having better performance for markovian computations.we compare two approaches for a markovian model in flexible manufacturing systems (fmss) using monte carlo simulation. the model which is a development of fazlollahtabar and saidi-mehrabad (2013), considers two features of automated flexible manufacturing systems equipped with automated guided vehicle (agv) namely, the reliability of machines and the reliability of agvs in a multiple agv jobshop manufacturing system. the current methods for modeling reliability of a system involve determination of system state probabilities and transition states. since, the failure of the machines and agvs could be considered in different states, therefore a markovian model is proposed for reliability assessment.

Traditional manufacturing has relied on dedicated mass-production systems to achieve high production volumes at low costs. As living standards improve and the demands for new consumer goods rise, manufacturing flexibility gains prominence as a strategic tool for rapidly changing markets. Flexibility, however, cannot be properly incorporated in the decision-making process if it is not well defin...

This paper examines a methodology for computing the probability of structural failure by combining neural networks (NN) and Monte Carlo simulation (MCS). MCS is a very powerful tool, simple to implement and capable of solving a broad range of reliability problems. However, its use for evaluation of very low probabilities of failure, of the order of magnitude currently found in structural reliab...

This paper presents estimation of reliability R P(X Y) of a system, for the cases when its strength (X) and stress (Y) follow exponential, normal or gamma distributions, using Monte Carlo simulation (MCS). First the parameters of strength and / stress are estimated and substituting them in the reliability expressions, in different cases, the estimates of reliability are obtained. Normal dis...
