Difference between MRP vs MPS

Difference between MRP vs MPS.

MRP 与MPS之间的差别;

Explain the diffenence between MRP & MPS,Though both components gives you the requirement list, what we gain out of MPS run rather than running MRP.what is the main idea behind this?

MRP & MPS 之间差别的解释,虽然它们都可以提供需求请单,但我们与期运行MPS倒不如运行MRP.它们后面什么才是最主要的概念??

The following might help in explaining the difference between MPS and its counter part MRP.

以下的文字也许能帮助解释MPS和它的组成部分MRP之间的差别；

Master Production Schedule(MPS):

主生产计划

MPS operates within only one level of the BOM, While MRP can be utilixzed throughout all levels of a material's BOM,if a MPS is run on a material,the necessary orders are planned at that level.Dependent requirements(if any) are placed on the next BOM level down,and then the process stops.

MPS 运算只考虑(成品)BOM的第一层,而MRP运行时遍及物料BOM的所有层次。当MPS在一个物料层级运行时,它需要在这个层级上的(所有)订单必须是已计划的,如果存在(任何)需求的话它会据BOM的下一层级排列，然后(MPS)运行结束;

Main Idea: Master production scheduling(MPS) is a form of MRP that concentrates planning on the parts or products that have the greate influence on company profits or which dominate the entire production process by taking critical resources.These items are marked as "A" parts (MPS Items) and are planned with extra attention.these items are selected for a separate MPS run that takes place before the MRP run,the MPS run is conducted without a BOM explosion so that the MRP controller can ensure that the Master schedule items (MSI)are correctly planned before the detailed MRP run takes place.

主要概念：MPS是由集中计划部分的MRP组成，对像为公司利润有重大影响的产成品，也或是在生产过程中起到决定性的资源；这些项目会被“A”标识（MPS 项目）并且被优先计划处理；在RUN MRP之前这些被标识的项次被MPS分隔开来，在RUN MRP明细发生之前，MRP的激发不考虑BOM经使MRP控制能确保MSI被正确的计划；
