MRP is the core function of ERP as long as it is "manufacturing", it will inevitably buy raw materials from the supplier to produce product sales to the demand side. This is also the manufacturing difference in the financial industry, commercial, mining industry (oil, mineral) The main features of the service industry. Any manufacturing business production activity is a manufacturing information system that is carried out around its products. MRP is the structure or material list of products (for food, medicine, and chemical industry "formula"). Integrated - a tapered product structure of a small lower under: The top layer is a factory product is a business in the business market sales department; the bottom is the raw material or matching piece of the purchase is the business of the enterprise materials supply department; The manufacturer is the business of the production sector. If you want to integrate the company's "sales" information in the unified planning guidance according to the needs of the needs, you can ink the basic file of the product structure (or bill). On the product structure reflects the connection between the dependence and quantity relationship between the various materials reflects the process flow and time period; in other words, it can explain the "period of time" commonly used in manufacturing production management through a product structure. ". MRP is mainly used to produce the manufacturing of "assembly" products, if the process (process, equipment or device) is integrated with product structure, can integrate the characteristics of the process industry. It is easy to say that MRP is a plan to ensure that there is neither shortage and not backlog stocks solve the contradiction between the manufacturing industry's concern and the contradiction. All ERP software uses MRP as its production plan and control module MRP is an indispensable core function of the ERP system. MRPII is an important component of ERP MRP to solve the integration of enterprise materials supply and demand, but has not noted the business benefits of enterprises. The main difference between MRPII with MRP is that it uses the concept of management accounting to illustrate the effectiveness of the implementation of the "Material Plan" to implement the product information with the information integration. Measuring the business efficiency of the company must first calculate the actual process of cost product cost. The material fee, labor fees and manufacturing of the material fees, the material fees, labor costs, labor costs, and manufacturing by the product structure of the MRP system. Fee (indirect cost) accumulates every layer of components until the final product. Further combination with marketing analysis of the profitability of various products. MRPII combines traditional account processing with the business of business, not only describes the current state of the account, but also traces the money-deranging amount of the funds. For example, the account payable of debt creditor relationships, accounts for integration with the procurement business and sales business. , With supplier or customer performance or credit integration, integrated with sales and production plans, etc., according to material position, quantity or value change "Transaction", which is directly generated by production activities. Automatic transfer login to the set borrowing relationship between the accounting subjects in the definition of transaction-related accounting, the "funds (financial accounts)" synchronization and unanimous changes in the "logistics (physical account)" changed the information of the fund information Status makes decisions in real time. ERP is a highly integrated information system that it necessarily reflects the integration of logistics information with fund flow information. Traditional MRPI II systems mainly include most of the manufacturing, supply and marketing and financial three parts of the ERP system cannot be across the ERP system. So the information integration of MRPI is not necessarily necessary to protrude MRPII since it is included in the ERP system. The image stated that MRPII has "melted" in ERP rather than "no longer exists." In short, from the perspective of management information integration, from MRP to MRPII to ERP is the continuous expansion of manufacturing management information integration and deepening each progress is a major quality leap but also a pulse. So what is the difference between ERP with MRPII? The world's economic situation, management ideas and information technology are constantly evolving. With the formation of the global economy, MRPI IT systems that integrate internal information integration, the MRPII system, which is unable to meet the company's diversified (multi-industry), cross-regional, multi-supply and sales channels, global management models. In the 1990s, with the rapid development of network communication technology and widely used manufacturing companies that transnational operations began to move toward higher management information system levels. What needs to be indicated again --MRPI is not "outmorting" but "not enough" cannot meet the needs of the new situation. ERP is the report of ERP concepts in Gartner Group Inc. In the early 1990s, the ERP concept is only based on the development of computer technology and invested various manufacturing information system management information systems. Development trends and changes; the application of Internet is not widely popular.
As practicing and developing e rp has now had deeper connotations, there are three main characteristics, and the main difference between ERP with MRPII: 1. ERP is a management information integration of Supply Chain Management (Supply Chain Management). In addition to the manufacturing, supply and marketing and financial function of traditional MRPI systems, ERP has also added transportation management of material circulation systems, warehouse management (supply and demand chain, production, need to have transportation and warehousing management issues between various links (Online Analytical Processingolap), after-sales service and quality feedback, real-time, accurately grasp the pulse of market demand; support the quality management, laboratory management, equipment maintenance and spare parts management of production and security system; support multinational management Country, multi-factory, multi-language, multilingual demand; support for multiple production types or hybrid manufacturing enterprises to engage discrete production, flow operation production and process production characteristics; support remote communication, web / internet / intranet / EXTRANET , E-Commerce, E-Business, Electronic Data Exchange (EDI); Support Workflow (Business Process) Dynamic Model Change and Information Processor Commands. In addition, corporate capital operation and investment management, various regulations and standard management are supported. In fact, the functionality of some ERP software has far exceeded the application range of manufacturing into an adaptive and wide application. But the manufacturing industry is still the basic application object of the ERP system. 2. Using the latest achievements of computer and network communication technology. The application of network communication technology is another main difference between ERP with MRPII. ERP system, in addition to the already commonly used, such as graphical user interface technology (GUI), SQL structured query language, relational database management system (RDBMS), object-oriented technology (OOT), fourth-generation language / computer auxiliary software engineering, client / Server and distributed data processing system, etc., more open different platform interoperability uses programming software for network technology to strengthen user-defined flexibility and configurable features to adapt to different industry users. need. The application of network communication technology enables the ERP system to achieve information integration of supply-demand chain management. 3. The ERP system is closely related to the business process reengineering referred to as the business process reengineering. The development of information technology has accelerated information transfer speed and real-time expansion of the coverage of the business, and the exchange of information for information is real-time processing for information on information, making corresponding decisions provide an extremely advantageous conditions. In order to enable business processes to foresee and respond to environmental change in the environment, the internal and external business processes must maintain information agility. As the information system inside the enterprise is not likely to master the live-changing global market dynamics, many bloated organizational institutions must also make effective responses to market dynamic changes in real time in real time. Therefore, in order to improve the competitive advantage of enterprise supply and demand chain management, it will inevitably lead to the reform of business business processes, information processes, and organizational institutions. This reform is not limited to the interior of the company, but the partner of the supplier and demand partners in the supplier is commended to consider the business process of the entire supply and demand chain. The technology and operations used by the ERP system application must be adjusted accordingly as the business process changes. Only in this way can the traditional MRPII system "strain" "increased" response "to the ERP system via network information on environmental changes in internal and external environment. The concepts and applications of BPR have extended from the interior of the enterprise to the business process and organization of the entire supply and demand chain of the market. ERP focuses on integration of various management information and CIMS (Computer Integrated Manufacturing System) focuses on the integration of technical information overlap but is also a complementary relationship. Whether the manufacturing industry implements the ERP system to achieve the needs of the nature, scale and development and business strategy of the company. However, regardless of how the ERP is highly planned for the long-term planning of corporate information construction. The first step in manufacturing information construction is still necessary and feasible from implementing MRPII. ERP's core management ideological erp core management ideas are supply-demand chain management. The supplier chain is directly translated by the original Supply Chain "Supply Chain" but every link on the substantive upper chain contains "supply" and "demand" two-meaning "supply" and "need" always relatively, accompanied by Born; foreign countries also called Demand / Supply Chain. The supply is always on the market economy. It is always necessary to have no need to have a need for demand. It is translated as a supply chain more exact.
