MRP和MRP II之间的区别

先决条件– ERP系统的演进

1.物料需求计划(MRP)：
开发于1970年代，可以管理任何组织需要的原材料，即公司需要的原材料都存储在数据库中。此外，它还告诉您任何材料的短缺。物料需求计划是工业生产计划和计划中广泛使用的方法。

MRP的函数是提供物料可用性，即用于按时生产需求数量。此过程涉及监视库存和需求，从而自动创建用于采购或生产的采购建议。 MRP的主要目标是确定所需的材料，所需的数量以及所需的时间。这是要素材料清单，并强调实际资产。

2.制造资源计划(MRP II)：
制造资源计划开发于1980年代，是对管理整个制造公司的闭环MRP的扩展。该系统提供了对所有功能区域有用的信息，并鼓励跨功能的交互。在这种情况下，制造单位下的任务是自动化的或与之相关的，因此最终的产量应提高。

它通过提供和订购有希望的功能来支持销售和市场营销。它是基础广泛的资源协调系统，在计划过程中涉及公司的其他领域，例如营销，财务和人力资源。

MRP和MRP II之间的区别：

MRP	MRP II
Stands for Material Requirements Planning.	Stands for Manufacturing Resource Planning.
Developed in 1970s.	Developed in 1980s.
Widely used approach for production planning and scheduling in industry.	Provides an information that is useful to all functional areas and encourages cross-functional interactions.
Aims at releasing and managing manufacturing orders and purchasing requisitions.	Aims to control relevant material flows and production capacity while also taking into account the relationship between these material flows and the required capacity.
MRP is simply about ensuring the materials which are available to manufacture a specific part in a specific volume.	It take care of all other aspects of a job including ordering, tracking inventory and ensuring capacity.
It takes inputs all in order to make sure you have the right amount of materials/labor/machinery on hand at any given time to satisfy the market or your company production goals.	MRP II uses additional data from accounting records and sales for further analysis and forecasting of manufacturing requirements.
