摘要：Job Shop Problem(JSP)是生产调度领域中的一类复杂的调度问题,高效JSP求解算法的研究与设计是JSP,乃至整个生产调度领域的关键研究内容。引入新的智能仿生算法shuffled Complex Evolution(SCE),以求解工件的最小最大完成时间为目标,通过序列映射方式将连续定义域空间中的变量映射到离散的组合优化问题空间中,同时采用基于工序编码的方式进行编码,最后使用顺序插入解码机制对其解码。并针对基本SCE算法在求解优化问题时求解质量差和求解速度慢等缺点,对算法中个体的进化过程进行改进,使个体进化的方向沿着当前群体最优解的方向进行。最后将此算法用于求解典型的Job Shop调度实例,结果表明,改进SCE算法在解决Job Shop调度问题上是有效的。

摘要：In this paper, the Authors present the designing of power system stabilizer (PSS) and static var compensator (SVC) based on chaos, particle swarm optimization (PSO) and shuffled frog leaping (SFL) Algorithms has been presented to improve the power system stability. Single machine infinite bus (SMIB) system with SVC located at the terminal of generator has been considered to evaluate the proposed SVC and PSS controllers. The coefficients of PSS and SVC controller have been optimized by Chaos, PSO and SFL algorithms. Fi-nally the system with proposed controllers is simulated for the special disturbance in input power of genera-tor, and then the dynamic responses of generator have been presented. The simulation results show that the system composed with recommended controller has outstanding operation in fast damping of oscillations of power system and describes an application of Chaos, PSO and SFL algorithms to the problem of designing a Lead-Lag controller used in PSS and SVC in power system.
