| 1 | Recent advances in system reliability optimization driven by importance measures显示文摘System reliability optimization problems have been widely discussed to maximize system reliability with resource constraints.Bimbaum importance is a wellknown method for evaluating the effect of component reliability on system reliability.Many importance measures(IMs)are extended for binary,multistate,and continuous systems from different aspects based on the Bimbaum importance.Recently,these IMs have been applied in allocating limited resources to the component to maximize system performance.Therefore,the significance of Bimbaum importance is illustrated from the perspective of probability principle and gradient geometrical sense.Furthermore,the equations of various extended IMs are provided subsequently.The rules for simple optimization problems are summarized to enhance system reliability by using ranking or heuristic methods based on IMs.The importance-based optimization algorithms for complex or large-scale systems are generalized to obtain remarkable solutions by using IM-based local search or simplification methods.Furthermore,a general framework driven by IM is developed to solve optimization problems.Finally,some challenges in system reliability optimization that need to be solved in the future are presented. | Shubin SI Jiangbin ZHAO Zhiqiang CAI Hongyan DUI | 2020 | Frontiers of Engineering Management2020，7，3： | 5 |
| 2 | Learning Bayesian network structure with immune algorithm显示文摘Finding out reasonable structures from bulky data is one of the difficulties in modeling of Bayesian network(BN), which is also necessary in promoting the application of BN. This paper proposes an immune algorithm based method(BN-IA) for the learning of the BN structure with the idea of vaccination. Furthermore, the methods on how to extract the effective vaccines from local optimal structure and root nodes are also described in details.Finally, the simulation studies are implemented with the helicopter convertor BN model and the car start BN model. The comparison results show that the proposed vaccines and the BN-IA can learn the BN structure effectively and efficiently. | Zhiqiang Cai Shubin Si Shudong Sun Hongyan Dui | 2015 | Journal of Systems Engineering and Electronics2015，26，2： | 3 |
| 3 | Integrated importance measure for multi-state coherent systems of k level显示文摘To verify the effectiveness of the integrated importance measure (IIM) for multi-state coherent systems of k level,the definition and physical meaning of IIM are demonstrated.Then,the improvement potential and Δ-importance measures are generalized to multi-state coherent systems based on the system performance level,and the relationships between IIM and traditional importance measures are discussed.The characteristics of IIM are demonstrated in both series and parallel systems.Also,an application to an oil transportation system is given.The comparison results show that: (i) IIM has some useful properties that are not possessed by traditional importance measures; (ii) IIM is effective in evaluating the component role in multi-state systems when the component reliability and the failure rate are simultaneously considered. | Xibin Zhao Shubin Si Hongyan Dui Zhiqiang Cai Shudong Sun | 2013 | Journal of Systems Engineering and Electronics2013，24，6： | 1 |
| 4 | Improved resilience measure for component recovery priority in power grids显示文摘Given the complexity of power grids,the failure of any component may cause large-scale economic losses.Consequently,the quick recovery of power grids after disasters has become a new research direction.Considering the severity of power grid disasters,an improved power grid resilience measure and its corresponding importance measures are proposed.The recovery priority of failed components after a disaster is determined according to the influence of the failed components on the power grid resilience.Finally,based on the data from the 2019 Power Yearbook of each city in Shandong Province,China,the power grid resilience after a disaster is analyzed for two situations,namely,partial components failure and failure of all components.Result shows that the recovery priorities of components with different importance measures vary.The resilience evaluations under different repair conditions prove the feasibility of the proposed method. | Guanghan BAI Han WANG Xiaoqian ZHENG Hongyan DUI Min XIE | 2021 | Frontiers of Engineering Management2021，8，4： | 0 |
