摘要
Abstract
There may be assembly interference between tasks that are not constrained by precedence relationships during product assembly,which causes the operation time of tasks to depend on the assembly order,increases the product assembly time,and af-fects the balance of the assembly line.Therefore,considering the mutual interference between tasks during assembly,a multi-ob-jective U-shaped dependent assembly line balancing optimization model is constructed with the objectives of workstation number,idle time balance index,assembly time,and assembly cost,and an improved Non-dominated Sorting Genetic Algorithm-Ⅲ(NSGA-Ⅲ)is proposed for solving it.The proposed algorithm introduces the local search characteristics of the variable neighborhood search algorithm to balance the relationship between exploration and exploitation of the algorithm,and designs encoding,decoding,population updating,and selection operations based on problem constraints.Finally,the efficiency of the algorithm is verified through case studies and practical analysis.关键词
