摘要
机加线平衡问题与缓冲区配置问题目前大多通过先平衡、再缓冲区配置的串行模式分步求解,难以得到全局最优的结果。针对柔性加工线设计问题,同时考虑设备选择、生产线构型、线平衡和缓冲区配置,利用多色集合理论构建工艺和工位约束矩阵,设计了包含工位信息组合、操作排序和分配、缓冲区容量配置的优先度编码模式,采用数值计算方法得到多失效模式下混联结构生产线的生产率,以生产率最大、成本最低和缓冲区容量最小为优化目标,提出一种多目标优化算法MOGAPSO获取集成优化方案,并通过缸体机加线实例进行了应用验证。
Transfer Line Balancing(TLB)problem and Buffer Allocation(BA)problem are usually solved independently,which causes difficulty to obtain a global optimal solution.To over come this difficulty,a coupling approach for machine selection,line configuration,TLB and BA was proposed for flexible machining lines.A group of operation precedence constraint matrixes and workstation constraint matrixes were constructed through polychromatic set theory.A new coding mode based on priority was presented to describe all the combinations of information for workstation,operation assignment and BA.An analytical model was applied to estimate the production rate of series-parallel production line with multiple failure modes.A MOGAPSO algorithm was proposed to calculate the collaborative problem,with optimization objectives of maximizing the production rate,minimizing the coast and buffer capacity.An engine cylinder machining line study was used to validate the proposed approach.
