Compared with the traditional binary state system,importance analysis of the multi-state system is more aligned with the practice. Because the multi-valued decision diagram( MDD) can reflect the relationship between the components and the system state bilaterally, it was introduced into the reliability calculation of the multi-state system( MSS). The building method,simplified criteria,and path search and probability algorithm of MSS structure function MDD were given,and the reliability of the system was calculated. The computing methods of importance based on MDD and direct partial logic derivatives( DPLD) were presented. The diesel engine fuel supply system was taken as an example to illustrate the proposed method. The results show that not only the probability of the system in each state can be easily obtained,but also the influence degree of each component and its state on the system reliability can be obtained,which is conducive to the condition monitoring and structure optimization of the system.展开更多

文摘This paper investigates control synthesis for motion planning under conditions of uncertainty,specifically in robot motion and environmental properties,which are modeled using a probabilistic labeled Markov decision process(PL-MDP).To address this,a model-free reinforcement learning(RL)approach is designed to produce a finite-memory control policy that meets complex tasks specified by linear temporal logic(LTL)formulas.Recognizing the presence of uncertainties and potentially conflicting objectives,this study centers on addressing infeasible LTL specifications.A relaxed LTL constraint enables the agent to adapt its motion plan,allowing for partial satisfaction by accounting for necessary task violations.Additionally,a new automaton structure is introduced to increase the density of accepting rewards,facilitating deterministic policy outcomes.The proposed RL framework is rigorously analyzed and prioritizes two key objectives:(1)satisfying the acceptance condition of the relaxed product MDP,and(2)minimizing long-term violation costs.Simulation and experimental results are presented to demonstrate the framework’s effectiveness and robustness.

文摘The enhancement of mobility has always been a research focus in the field of thin-film transistors(TFTs).In this paper,we report a method using ultra-thin HfO2to improve the electrical performance of indium gallium zinc oxide(IGZO)TFTs.HfO2not only repairs the surface morphology of the active layer,but also increases the carrier concentration.When the thickness of the HfO_(2) film was 3 nm,the mobility of the device was doubled(14.9 cm^(2)·V^(-1)·s^(-1)→29.6 cm^(2)·V^(-1)·s^(-1)),and the device exhibited excellent logic device performance.This paper provides a simple and effective method to enhance the electrical performance of IGZO TFTs,offering new ideas and experimental foundation for research into high-performance metal oxide(MO)TFTs.
