管理信息化：优化生产中的物流活动(编辑修改稿)内容摘要：

em ”推动“生产体系 • In traditional manufacturing, various production schedules are released to all processes。 ponent making and assembly. 在传统的生产中 ,各种生产计划被传达到各个工序 ,部件生产和组装部门 . The Push System (cont.)”推动“ • These partmaking processes produce the parts in accordance to their schedules and transport the parts to the next process. 部件生产部门按照收到的计划生产并把成品部件运送到下一道工序 . The Push System (cont.)”推动“ • This method makes it difficult to promptly adapt to changes. 这种方法使生产很难迅速对变化作出反应 • Each production schedule must be changed at each process simultaneously. 每个工序的生产计划都必需同时变化以适应同步生产 The Push System (cont.)”推动” The Result导致 : – The pany must hold extra inventory among all processes. –公司不得不在各个工序保持额外的库存 – This creates an imbalance of stock between processes. –各工序间的库存达不到平衡 The Pull System “拉动”生产体系 In contrast, in a PULL SYSTEM, each process will withdraw the parts it needs from the proceeding process. 相反 , “拉动”生产体系要求各个工序仅需从上一道工序提取自己所需要的部件 . B A “ production” kanban “ withdrawal” kanban Product部件 Product部件 Market 供应超市 Supplying Process 供应工序 Customer Process 客户工序 “生产”指示板 “拒收”指示板 The Pull System (cont.)”拉动”体系 Since only the finalassembly process can accurately know the necessary timing and quantity of parts required, they are the only ones to receive a schedule. 因为只有制造准确地了解所需时间和部件数量 ,以只要制造收到生产计划即可 . Assembly Stockfit准备 Stitching缝纫 Assembly制造 Shipping装船 Weekly Schedule每周生产计划 Final Assembly receives a schedule and pulls from the Market Place. Stitching and Stockfit replenishes the Market Place. 制造接受生产计划 ,并借助“供应超市”拉动生产 .缝纫和准备向“供应超市”补充部件 . Production Control 生产控制 The Pull System (cont.)”拉动”体系 With the schedule, the finalassembly goes to the supplying departments and withdraws what parts are needed. 根据生产计划 ,制造到供应车间去提取所需部件 . The Pull System (cont.)”拉动“生产 The preceding operation then produces the replacements of the parts withdrawn by the subsequent process. 这样 ,前一道工序开始生产被下一道工序提走的部件以补充所需 .
