CRM and SCM
CRM (Customer Relationship Management) is a customer relationship management. SCM (Supply Chain Management) is a supply chain management.
From the ERP contains a scope of management perspective, it is in MRPII on the basis of increased CRM and SCM, it is called ERP, so from a management point of view, CRM, and SCM is a subset of ERP.
PLM and PDM
PLM (Product Lifecycle Management) is the product life cycle management product life cycle usually consists of products, investment period, growth, maturity and decline stages of 4. PLM itself is a way of thinking, not the management of specific means, at this point and based on MRP logic and computer and network technology, ERP is a big difference. If the product life cycle management, then the PLM and ERP management process is in many overlapping, so that is the intersection of PLM and ERP.
PDM (Product Data Management) is a product data management. PDM is based on technology standardization as the basis, to computer-aided design CAD (Computer Assistant Design) as a means of product technical information is summarized an approach to management. It can be said, PDM is a concrete expression of PLM in one of the methods, and the output of PDM is the basis of ERP data, my personal view is that the PDM to look at the intersection as the ERP.
APS and MES
APS (Advanced Planning and Scheduling, also has said that Advanced Planning System) is generated due to defects in MRP algorithm. MRP logic is assumed: the material evenly consumption, the limited demand for material can be controlled by an independent (I do not like to use the concept of infinite capacity, I think that is misleading, is an insult to MRP logic), a stable EOQ, etc. In fact, APS assumptions and MRP logic is the same, the difference is: APS is the MRP logic, refinement and optimization. The performance of the specific conditions and constraints that more optimal algorithm (MRP logic is that the whole solution). Therefore, APS is also a subset of the ERP.
MES Manufacturing Execution System
MES management community in the 1990s the United States put forward a new concept, MESA (MES International Federation) on the MES is defined as: MES through the transmission of information from the order to reach the next product to complete the entire production process to optimize the management. When the factory where real-time event, MES can be a timely response to this, reporting, and use current and accurate data to guide them and deal with.
From this definition we can easily see, MES is an ERP program monitoring and feedback, MES out of the box price of ERP management is of no value, so, MES is also a subset of the ERP.
APS is to generate plans, MES is the monitoring and feedback programs, the two can be said to be relatively independent.
PMC
PMC (Product Material Control) means for production and material control. It is usually divided into two parts:
PC: production control or production control (Banglore, Japanese companies, commonly called the tube). The main functions of production planning and production schedule control.
MC: Material Control (commonly known as material control), the main functions of the materials program, please purchase, material scheduling, materials control (bad material control and are
regular access to material control) etc. |
