Non-homogeneous Poisson process (NHPP) models are widely used for repairable system analysis. Different NHPP models have been developed for different applications. It has been noticed that almost all the existing models apply only a single model for the entire system development or operation period. However, in some circumstances, such as when the system design or the system operation environment...
The temperature field and the coupling mechanism of the airflow in transportation channel was analysed by the currency software FLUENT, based on the conservation principle, by using the single-phasic multicomponent model. The simulation result was also compared with the temperature measured in mine. Then the atomizer spray refrigeration process of two schemes were simulated, considered the turbulent...
Repairable inventory is an important research field of improving operational readiness and reducing LCC (life cycle cost) for equipments. In spite of the sophisticated models and techniques were developed to manage the spares parts inventory in a multi-echelon system successfully, some restrictions still exist on its application to real case problems. To surpass some of these limitations a simulation...
We demonstrate a ldquotrading time for signalrdquo approach for the measurement of species-specific optical transmission, in ambients rich in particulates, using the example case of a turbulent fluidized bed reactor. The method is introduced on the basis of Monte Carlo simulations, as well as analysis of experimental data, of beam propagation for a range of path lengths, and particle concentrations...
