为了更好地解决开放式作业域的混流装配线排序问题,建立了以最小化超载时间与平顺化零部件消耗为优化目标的混流装配线排序问题数学模型,并提出了一种禁忌粒子群算法求解该排序问题。针对标准粒子群算法在算法后期搜索精度不足以及容易陷入局部最优不能跳出的缺陷,引入了禁忌搜索算法建立了对最优微粒的重搜索机制来提高算法跳出局部最优的能力,同时给出了禁忌算法中候选解、禁忌表长度、禁忌对象、藐视准则的设置方法,并采用了随机权重的惯性权重更新方式来平衡算法的全局和局部搜索能力,最后建立了禁忌粒子群的算法流程。通过比较禁忌粒子群算法与遗传算法的实例计算结果,验证了禁忌粒子群算法在求解开放式作业域的混流装配线排序问题中的有效性和优越性。 相似文献

混合粒子交互微粒群算法 总被引:2,自引:0,他引:2
针对现有微粒群算法仅考虑单一一种引斥力规则使得其搜索能力存在的不足,考虑在不同搜索阶段采用不同的引斥力规则,提出搜索后期引力增强型混合引斥力微粒群算法(LAPSO算法)。利用拟态物理学中的引斥力规则使粒子保持多样性,提高算法的全局搜索能力;当进入到具有全局最优解的区域时,增强引力作用、减少斥力作用,利用比自身适应度好的粒子和全局最优解粒子的引力作用,提高算法的局部搜索能力。为进一步提高LAPSO算法的优化性能,将其与混合全连接型-环形拓扑结合,提出混合粒子交互微粒群算法(HIPSO算法)。通过6个Benchmark函数进行测试,结果表明,与现有的扩展-微粒群、微-微粒群、中值导向-微粒群等算法相比,所提的LAPSO算法、HIPSO算法具有较好的种群多样性,具有更好的寻优精度、收敛率和最优解搜索能力。结合文献[7]中的柔性流水车间调度离散优化实例和文献[20]中的超声振动加工工艺参数连续优化实例,验证了HIPSO算法的最优解搜索能力。 相似文献

Particle swarm optimization (PSO) and differential evolution (DE) have their similarities and compatibility in the design
update process, such that a new design vector is determined by using neighborhood designs under algorithm control parameters.
The paper deals with an integrated method of a hybrid PSO (HPSO) algorithm combined with DE in order to refine the optimization
performance. PSO and DE also possess common characteristics compared with genetic algorithm (GA). The crossover- and mutation-like
operators are suggested in the HPSO. A bounce back method is also implemented to prevent the design from locating out of design
spaces during the optimization process. For the purpose of further enhancing the search capabilities, such HPSO is combined
with the Q-learning that is one of efficient reinforcement learning methods. Using a number of nonlinear multimodal functions
and engineering optimization problems, the proposed algorithms of HPSO and HPSO with Q-learning are compared with PSO DE and
GA.

A hybrid discrete particle swarm optimization algorithm for the no-wait flow shop scheduling problem with makespan criterion 总被引:2,自引:2,他引:0

This paper proposes a novel hybrid discrete particle swarm optimization (HDPSO) algorithm to solve the no-wait flow shop scheduling problems with the criterion to minimize the maximum completion time (makespan). Firstly, a simple approach is presented in the paper to calculate the makespan of a job permutation. Secondly, a speed-up method is proposed to evaluate the similar insert neighborhood solution. Thirdly, a discrete particle swarm optimization (DPSO) algorithm based on permutation representation and a local search algorithm based on the insert neighborhood are fused to enhance the searching ability and to balance the exploration and exploitation. Then, computational simulation results based on the well-known benchmarks and statistical performance comparisons are provided. It is concluded that the proposed HDPSO algorithm is superior to both the single DPSO algorithm and the existing hybrid particle swarm optimization (HPSO) algorithm from literature in terms of searching quality, robustness and efficiency. 相似文献

A new heuristic algorithm is proposed for the problem of finding the minimum makespan in the job-shop scheduling problem. The new algorithm is based on the principles of particle swarm optimization (PSO). PSO employs a collaborative population-based search, which is inspired by the social behavior of bird flocking. It combines local search (by self experience) and global search (by neighboring experience), possessing high search efficiency. Simulated annealing (SA) employs certain probability to avoid becoming trapped in a local optimum and the search process can be controlled by the cooling schedule. By reasonably combining these two different search algorithms, a general, fast and easily implemented hybrid optimization algorithm, named HPSO, is developed. The effectiveness and efficiency of the proposed PSO-based algorithm are demonstrated by applying it to some benchmark job-shop scheduling problems and comparing results with other algorithms in literature. Comparing results indicate that PSO-based a 相似文献
