＜正＞ The basic principle of particle swarm optimization （PSO） is introduced briefly in the paper. Sufficient experiments were done on inertia weight that is an important parameter in the algorithm. The selection difference between fixed and time-variant inertia weight was analyzed. And the influence of inertia weight on the algorithm performance was analyzed in detail from different aspects, including the problem dependence, swarm size and topologic structure. The result indicates the inertia weight has little problem dependence, and with the increase of the population its value should decrease properly. The selection of inertia weight has more freedom in the local version of PSO.

Building an effective resilient supply chain system (RSCS) is critical and necessary to reduce the risk of supply chain disruptions in unexpected scenarios such as COVID-19 pandemic and trade wars. To overcome the impact of insufficient raw material supply on the supply chain in mass disruption scenarios, this study proposes a novel RSCS considering product design changes (PDC). An RSCS domain model is first developed from the perspective of PDC based on a general conceptual framework, i.e., function-context-behavior-principle-state-structure (FCBPSS), which can portray complex systems under unpredictable situations. Specifically, the interaction among the structure, state and behavior of the infrastructure system and substance system is captured, and then a quantitative analysis of the change impact process is presented to evaluate the resilience of both the product and supply chain. Next, a case study is conducted to demonstrate the PDC strategy and to validate the feasibility and effectiveness of the RSCS domain model. The results show that the restructured RSCS based on the proposed strategy and model can remedy the huge losses caused by the unavailability of raw materials.

针对目标和杂波先验知识不准确时面向目标参数估计的雷达波形设计问题,同时兼顾功率放大器对低峰均比(PAR)波形的需求,该文提出一种信号相关杂波背景下雷达低PAR稳健波形设计方法。首先,以最大化互信息(MI)为优化准则,构建了估计波形优化模型;接着,通过提取协方差矩阵特征值,构建了关于目标和杂波矩阵的不确定集模型;然后基于极大极小化准则,将关于矩阵的非凸优化问题转化为关于特征值的凸问题;最后,基于序列线性规划方法给出了波形的优化解。分析表明,所提方法产生的波形具有较好的有效性和稳健性能。
