Material Requirements Planning _MRP_ by fdjerue7eeu


									Material Requirements Planning (MRP)
Material Requirements Planning (MRP)
   How organizations can we allotted time, the provisions of the De Dian, according
to the number of required Dedao really need the materials, in other words, Jiu Shi
Guan Li inventory production planning how to meet the requirements of this program
is to solve the Wuliaoxuqiu. MRP at first appeared in the United States by the
Association of American Production and Inventory Management initiated and
MRP is a computer-based production and the preparation of the implementation of
control systems, it is not only a new project management methods, but also a new
organization of production. The emergence and development of MRP, caused
production management theory and practice changes. MRP is based on the total
production schedule set forth in the final product delivery date, the work required to
complete the time, the preparation of all lower parts of the production schedule, the
various parts of the procurement of foreign progra ms and the amount of time,
domestic production sector should be carried out to determine the timing and amount
of processing. Once the operation can not be completed according to plan, MRP
system of procurement and production schedules of Shi Jian He 数量 be adjusted, so
that all operations meet the actual situation in order of priority.
1, MRP's main objective
MRP system, the main objective is to control the company's inventory
levels to determine production priorities to meet the delivery requirements, the
efficiency of production runs highest. Concrete can be summarized as follows:
① purchase appropriate number and variety of parts. Select appropriate time order,
maintain the lowest possible inventory levels.
② timely access to the production of various raw materials and parts required to
ensure the timely supply customers products they need.
③ planning system to maintain a balanced load.
④ rules of manufacturing activities, procurement activities and product delivery date.
ERP MRP Ⅱ is the difference with what? ERP by the U.S. Gartner (Gartner Group
Inc.) First proposed in the early 90's, when the concept of ERP Report,
only the basis of computer technology and supply chain management inference types
of manufacturing management information systems in the information age trends and
changes; time, Internet applications are not widely popular. With the practice and
development, E RP has been a deeper meaning, summed up in three characteristics,
but also ERP MRP Ⅱ with the main difference:
1. ERP is for supply chain management (Supply Chain Management) in the
management of information integration. In addition to traditional MRP Ⅱ ERP
system manufacturing, supply and marketing, finance function, the function also adds
support for material flow system, transportation management, warehouse management
(supply chain for reference, productivity, need to have all links between the
management of transport and storage issues); support online analytical processing
(Online Analytical Processing, OLAP), after-sales service and quality feedback in real
time accurately the pulse of the market demand; support production security system,
quality management, laboratory management, equipment maintenance and spare parts
management; support multi-country cross-border business area
Multi-plant, multi- lingual, multi-currency demand; support a variety of production
types or mixed manufacturing companies, convergence of the discrete manufacturing,
assembly- line production and process production characteristics; support remote
communications, Web / Internet / Intranet / Extranet, e- Business (E-commerce,
E-business), electronic data interchange (EDI); support workflow (business process)
changes the dynamic model of command and integration of information processing
procedures. In addition, support for venture capital operations and investment
management, the various regulations and standards of administration. In fact, the
current number of ERP software features go far beyond the scope of application of the
manufacturing sector has become a strong adaptability and significance broad
application of enterprise management information system. However, manufacturing is
still the basic application of ERP system objects.
2. Use of computer and network communication technology, the latest achievements.
Network communication technology is the ERP MRP Ⅱ with another major
difference. ERP systems have been widely used in addition to the graphical user
interface technologies such as (GUI), SQL structured query language, relational
database management system (RDBMS), object-oriented technology (OOT),
fourth-generation language / computer-aided software engineering, client / server and
distributed data processing systems and other technologies, should also be more open
to achieve interoperability with different platforms, using suitable programming
software, network technology, enhanced flexibility and user-defined features can be
configured to meet the needs of users of different industries. Network communication
technology, to enable ERP systems to achieve supply chain management, information
3. ERP system and Business Process Reengineering (Business Process Reengineering,
referred to as BPR) are closely related. Development of information technology has
accelerated the speed and real- time information transmission, and expanded coverage
of business and information exchange capacity for enterprise real- time processing of
information to make appropriate decisions to provide an extremely favorable
conditions. In order to enable their business processes to anticipate and respond to
environmental changes, internal and external business processes of enterprises must
be agile to keep the information clear. As the information systems within the
enterprise can not immediately grasp the ever-changing global market dynamics as
bloated multi- level organizations are bound to real-time on the market can not quickly
respond effectively to dynamic changes. Therefore, in order to improve supply chain
management business competitive advantage, will definitely bring business processes,
information flow and organizational reform. This reform has been limited to internal,
but the supply chain partners include both supply and demand come in, the system for
the entire supply chain business processes. ERP system application and operation of
the technology used must be able to change as business processes and adjust. Only in
this way can the traditional MRP Ⅱ system to environmental change
"contingency (Active)" rose to ERP system through the network
information on environmental changes inside and outside "agency
(Proactive)". BPR concept and the application has been extended to the
enterprise from the enterprise market and supply and demand of the market
throughout the supply chain business processes and organizational restructuring.
ERP focuses on the integration of various management information, and CIMS
(Computer Integrated Manufacturing System) focuses on the integration of technical
information between them overlapping in content but is a complementary relationship.
Manufacturing ERP system is realized, when achieved, depends on the nature, scale
and development and business strategy needs. But no matter what the height should
be carried out from the ERP enterprise information construction long-term planning.
As a first step in manufacturing information technology, starting from the
implementation of MRP Ⅱ, most enterprises are still necessary and viable option.
