摘要
针对装配线平衡与物料配送不配套现象,对装配线平衡和物料配送的协同优化问题进行了研究,建立了装配线平衡最少工作站、最少均衡系数及物料配送路径最短多目标协同优化模型,同时设计了NSGA-II算法对模型进行求解。对算法的拥挤度和拥挤距离的缺点进行了分析和改善,提出的0~1编码方式能提高算法的适用性,对算法局部搜索深度较差引入了基于高斯分布和混沌扰动的变异算子。最后,通过具体实例验证了模型和算法的可行性和有效性。
To sovle the phenomenon of assembly line balancing and material distribution not matching,assembly line balancing and materials cooperating delivery was studied,The optimized model was established to minimized the numer of workstations,the least equilibrium coefficient and the shortest material distribution paths,and designed the NSGA-II algorithm to solve the model.Analyzed and improved the weakness of algorithm’s crowded degree and distance,improved algorithm’s poor local search with gaussian distribution and chaos perturbation mutation operator,the 0~1 encoding can improve the applicability of the algorithm.Finally,through specific examples verified the feasible line and effectiveness of the model and algorithm.
