中文摘要：
针对第Ⅱ类装配线平衡问题,提出一种基于可行装配序列的改进蚁群算法。算法基于可选操作集合的动态改变和工位作业时间优化目标的更新,给出操作分配至工位的分配准则。针对该问题的特点,提出工位和操作间的信息素、操作和操作间的信息素两种信息素。蚂蚁根据前者和启发式因素的权值为当前工位随机选择一项操作为该工位的首项操作,依据后者和启发式因素的权值为已选操作组合随机选择一项操作作为其组合操作。利用与经典测试算例的比较及工业实例的运行,验证了算法的正确性和工业应用优势。
英文摘要：
Aiming at the type Ⅱassembly line balancing problem（SALBP-2）,an improved ant colony optimization based on feasible assembly sequences was proposed.Based on the dynamic changes of candidate task set and the updating of station time optimization goal,a principle of assigning task to station was designed.By taking the characteristics of SALBP-2 into consideration,two pheromones were introduced into algorithm,which included station and task,task and those just among tasks.Ants selected the first task to station randomly according to the first pheromone and the weight of heuristic factors,and selected other tasks to station randomly according to the second pheromone and the weight of heuristic factors.Through the operation of industrial case and the comparison with classic test example,the validity and efficiency of the proposed algorithms was confirmed.
