Selective maintenance is an important condition-based strategy for multi-component systems, where optimal actions are identified to maximize the success likelihood of subsequent missions. Most existing works on selective assumed that after each mission, components' states can be precisely known without additional efforts. In engineering scenarios, components in a system need revealed by inspections usually inaccurate. Inspection activities also consume limited resources shared with...
Selective maintenance, as a pervasive maintenance policy in both military and industrial environments, aims to achieve the maximum success of subsequent missions under limited resources by choosing an optimal subset feasible actions. The existing works on selective optimization all assume that condition components system can be perfectly observed after completes last mission. However, such premise may not always true reality due accuracy/precision sensors or inspection instruments. To fill...
Abstract Most engineering systems operate under stochastic dynamic environments. The variability and stochasticity of environmental conditions have a non‐negligible impact on the failure behavior systems. This article develops reliability modeling assessment framework for operating Markovian environment. environment is characterized by continuous‐time Markov chain. Using cumulative exposure principle, time scale, resulting from effect environment, computed via reward model. Based above...
As k-out-of- n systems have widespread applications in engineering practices, their reliability modeling and evaluation are a great concern of community. However, most reported works on based the premise that all components s-independent. Such simplified treatment may not be realistic as system often suffer same working or environmental conditions and/or interact with one another, resulting dependency between failure processes. To characterize such evaluation, copula-based for dependent...
The reliability function of a specific individual system can be dynamically updated by utilizing inspection data collected over time. However, due to limited resources, such as time, budget, and manpower, it is oftentimes impossible collect all the for components, subsystems, entire simultaneously. There an urgent need optimally allot resources across multiple physical levels system, so identify health status and/or its subset components interest accurately possible facilitate ensuing...
It is important to study the vibration characteristics of impeller rotor an axial flow pump for avoiding resonance and ensuring safe stable operation pump. Based on fluid-structure coupling method considering compressibility fluid, equation fluid solid solved by inserting APDL command into ANSYS Workbench platform. The natural frequencies runner horizontal in water reduction coefficients each order are obtained, distribution modes analyzed. Additional mass theory used analyze reasons...
Due to the sea water intrusion and development trend of using large-scale ships, more stringent requirements are put forward for safety delivery process mooring equipment operation shiplock. The maximum loads shiplock, i.e., floating column (FMC), generally occurred at end delivery. superimposed effect turbulent flow marine corrosive environment can accelerate failure structure which leads incidents, including structural damage FMC breakage lines ship, etc. is mostly influenced by three...
