浅析生产物流计划之物料需求计划 Material requirements of production logistics plan 厂内物流是依据出产方案、物料需要方案以及出产排程的有用施行所进行的一系列办理作业，并且出产物流的根本作业就是依照物资需要的指令，准时保量无差错地将出产所需物资配送到现场和每一个作业中心，出产物流的方案和办理都是围绕着MRP来进行作业的，由此可见MRP在出产物流方案中的重要程度，所以很有必要对它进行透彻的剖析与研讨。MRP于20世纪60年代起源于美国，它依据产物结构各层次物料的隶属和数量联系，以每种物料为方案目标，以竣工日期为时刻基准倒排方案，按提前期长短区别各种物料下达方案时刻的先后顺序，即MRP的根本任务是从结尾产物的出产方案（独立需要）导出关联物料（原材料、零部件等）的需要量和需要时刻（关联需要），依据物料需要时刻和出产（订购）周期来断定其开端出产（订购）的详细时刻。其间结尾产物需要量由主出产方案决议，关联物料的需要量能够经过物料清单和库存信息断定，而需要时刻则能够用倒序排产法核算得出。 According to the effective implementation of internal logistics, production plan and material needs to plan production schedule for a series of processing operations, basic operation and production logistics is in accordance with the supplies needed instruction, on time and without errors will produce materials needed for distribution to the scene and each one of the operations center, production logistics plan and management is around MRP to work, in production logistics plan important so MRP, so it is necessary to analyze and study thoroughly on it. The origin of MRP in the nineteen sixties to the United States, it according to the product structure of each level of membership and the number of contact materials, to each kind of material for program goals, with completion dates for the time standard inverted scheme, according to lead time length differences of various materials issued scheme of time sequence, which is the fundamental task of MRP is from the production plan. Product (independent need) derived relations material (raw materials, spare parts etc.) requirements and needs moment (association need), according to material need time and production cycle (order) to determine the beginning of production (the order) with time. The end product requirement by the main production plan decision, demand correlation material can pass the bill of materials and inventory information that needs time, and can be used in reverse scheduling method calculates the. 倒序排产是核算开工日期及竣工日期的一种办法，是指将MRP断定的订单完结时刻作为起点
