ERP and PLM MES and other contact management software
First need to be explained that the management philosophy and management software are different when different software vendors of software are placed in the same name in front of you, you will find that each of the management philosophy embodied in the software is different. So my analysis is starting from a management point of view, rather than from some of the software perspective.
ERP history of development
I first introduced the ERP is a good reason: According to my personal understanding, the other management is running under the framework of ERP, ERP is a subset or intersection.
Let's take a look at MRP (Material Requirement Planning): inventory control, along the more scientific (at least in theory) route development. The basic concept of economic quantities published in 1915 to determine the reorder point of the statistical methods proposed in 1934 by the R.H. Wilson. After World War II, scientists found that using operations research and probability theory to control the production and inventory is a more rational approach. However, these very complex inventory management system techniques rarely was applied. Until the late 1950s, the computer was to make extensive use of complex work become possible. In 1957, the establishment of the APICS (American Production and Inventory Control Society), for the MRP, MRPII, ERP development of the theory laid a solid foundation.
Management, demand-driven generation of theory, theory into practice again. MRP logic actually born in the 1960s, was marked by independence of the distinction between needs and other needs. In fact to the 1970s, MRP concept was realized, was officially applied to the management to go. Focus on the logic of MRP is to address what is produced when the number of production problems. This basic logic of strong support for the subsequent development of MRPII and ERP.
In the 1980s, people manufacturing, finance, sales, purchasing, engineering, technology, integration of the various subsystems as an integrated system, and is called manufacturing resource planning (Manufacturing Resource Planning) system, initials, or MRP, material requirements in order to distinguish Planning System (also abbreviated as MRP) but is charged as MRP II. As can be seen, MRPII different from MRP and MRP is the only enterprise solution production system problems, MRPII to address is the issue of business to achieve the biggest sign is that a combination of financial and production systems. MRP II can be a good program, under the efficient use of manufacturing resources, control of funds used to shorten the production cycle, reduce costs, the full embodiment of the in-house logistics, capital flow and information flow management. It is the most significant effect is to reduce inventory levels and reducing material shortages.
In the 1990s, with the rapid development of the Internet, enabling enterprises to bring all parties concerned, the course of operation, such as suppliers, manufacturing plants, distribution networks, customers, into a tight supply chain, the question arose ERP (Enterprise Resources Planning). Therefore, it can be said: ERP is in MRPII, based on the expansion of operations links the upstream (supply side) and downstream (customer) management.
As for emerged after the concepts of ERPII always been separated from the ERP framework.
Because, according to IS09000 standards, corporate governance can be divided into customer-oriented processes, including: sales, design and development, production, procurement, management processes and support processes include: document control, human resources, measurement analysis and improvement and so on.
Now we look at the ERP contain the contents of it can be said: ERP covers all of an enterprise customer-oriented processes, and part of the management process and support processes. |
