Modelling spare parts dynamics by multi-state Monte Carlo simulation
نویسندگان
چکیده
In this paper, we resort to Monte Carlo simulation for achieving a realistic modelling of the dynamics of a system supported by spare parts. The spare dynamics, namely the start-up of a spare unit upon failure of an on line unit, is caught by means of the multi-state correlation method previously introduced by some of the present authors to describe stand-by and load-share dependencies. The Monte Carlo simulation model is embedded within a genetic algorithm multiobjective search for the maximization of the system revenues and the minimization of the total spares volume.

Gyration Radius and Energy Study at Different Temperatures for Acetylcholine Receptor Protein in Gas Phase by Monte Carlo, Molecular and Langevin Dynamics Simulations
The determination of gyration radius is a strong research for configuration of a Macromolecule. Italso reflects molecular compactness shape. In this work, to characterize the behavior of theprotein, we observe quantities such as the radius of gyration and the average energy. We studiedthe changes of these factors as a function of temperature for Acetylcholine receptor protein in gasphase with n...

Potassium Channels allow potassium flux and are essential for the generation of electric current acrossexcitable membranes. Potassium Channels are also the targets of various intracellular controlmechanisms; such that the suboptimal regulation of channel function might be related to pathologicalconditions. Realistic studies of ion current in biologic channels present a major challenge for compu...

متن کاملA novel approach for modelling complex maintenance systems using discrete event simulation
Existing approaches for modelling maintenance rely on oversimplified assumptions which prevent them from reflecting the complexity found in industrial systems. In this paper, we propose a novel approach that enables the modelling of non-identical multi-unit systems without restrictive assumptions on the number of units or their maintenance characteristics. Modelling complex interactions between...
