What Is Manufacturing Resource Planning?
Manufacturing resource planning is based on the overall optimal, using scientific methods to implement reasonable and effective planning, organization, control and coordination of various manufacturing resources and all aspects of production and operation of the enterprise to achieve both continuous and balanced production and maximum Management methods that reduce the inventory of various items and thereby improve the economic efficiency of the enterprise.

Manufacturing Resource Planning
- Manufacturing Resource Planning is abbreviated as MRP-II, it is the English abbreviation of Manufacturing Resource Planning, it is based on
Overview of Manufacturing Resource Planning
- After the 1990s, major changes have taken place in the world economic structure. The common problem facing manufacturing companies is more intense market competition. In the competition, technological factors have become increasingly important. If companies lose their technological advantages, they will certainly Losing its competitive advantage, therefore, seeking technological advantage is the need for the survival of modern manufacturing. On the one hand, manufacturing companies find that it is impossible to effectively participate in market competition based on the resources of their own companies. Instead, they must integrate the parties involved in the manufacturing process, such as suppliers, customers, manufacturing plants, and distribution networks, into a tight supply chain. Can effectively arrange the production, supply, and sales of enterprises; on the other hand, in some enterprises it is "multi-variety and small-batch production" and "mass-batch production"
- Manufacturing Resource Planning
- The development direction of MRP-II is roughly as follows
MRPIII Manufacturing Resource Planning MRP-III
- It is a combination of MRP-II and JIT (Just In Time, Just-in-Time), plus expert system (ES), concurrent engineering (CE) and the management staff responsible for the operation of the system.
- MRPIII is composed of MRP-II, JIT, CE, ES and their managers. In this system, each part exerts its own expertise in different production stages: MRP-II is used to execute long-term planning; JIT is used to control the implementation of short-term planning, which can support a mixed-mode manufacturing environment, and can take into account "multi-variety" "Small-batch production" and "mass-batch production" are two types of production that improve the company's ability to respond and market competition; under the control of a program system with a large amount of expert knowledge and experience, it assists in decision-making on some regular issues; and For unexpected situations and strategic issues that may occur randomly, the system works through human-computer interaction intervention. The use of advanced concurrent engineering technology is to enable engineering design, process design, engineering management, manufacturing and other stages to be properly linked with each other in accordance with the internal organization of the engineering organization, in order to minimize the lead time of each stage In this way, all aspects of work can be carried out at the same time, greatly shortening the product production cycle, improving productivity, product quality and service levels, and enhancing the competitive advantage of enterprises.
DMRPII Manufacturing Resource Planning Distributed DMRP-II
- Distributed DMRP-II is a bottom-up production management method. Traditional MRP-II is a top-down process, and one of its major flaws is static lead time. It divides the enterprise into units with high autonomy, each unit and database establishes its own MRP-II system, and there is an MRP-II responsible for dispatching orders to each unit, and each unit can dynamically based on its existing capabilities and The load is arranged, and the overall lead time of the system is dynamically determined by the load situation of each production unit. Therefore, the load is balanced and the flexibility is enhanced, which effectively solves the static lead time and capacity change in traditional MRP-II. Not sensitive.
LP Manufacturing Resource Planning Lean LP
- Lean Production LP (Lean Production) integrates advanced manufacturing technologies based on MRP-II, such as JIT, TQM (Total Quality Management) and manufacturing according to customer requirements. A production organization and management model proposed by Honda's advanced production methods. Its characteristic is to remove all useless things in all links of the enterprise, that is, the principle of the arrangement of each employee and his post is to add value, otherwise they will be removed.
ERP Manufacturing Resource Planning ERP
- ERP (EnterpriseResourceplanning) Enterprise Resource Planning, which is based on MRP-II, expands the management scope, gives a new structure,
- Integration with manufacturing activities within the enterprise and the manufacturing resources of the supplier reflects the idea of manufacturing according to user needs.
- The basic idea of ERP is to consider the manufacturing process of a manufacturing company as a tightly connected supply chain, which includes suppliers, manufacturing plants, distribution networks, and customers; divide the company's interior into several supporting groups that work together, such as finance , Marketing, sales, quality, engineering, etc., as well as monitoring and management of competitors. In ERP, many classic MRP-II functional subsystems have become more flexible. For example, the operation process will be integrated with the capability plan in order to make MRP-II add real-time features, reduce job batches and conversion time; BOM / recipe management The system will be assembled according to the idea of group technology, which can be easily manufactured when there is no material. ERP emphasizes the ability of enterprises to control in advance, it provides enterprises with real-time analysis capabilities on key issues such as quality, adapting to changes, customer satisfaction, and performance. It also provides planners with a variety of simulation functions and financial decision support systems to enable them to analyze what is going to happen every day instead of doing monthly analysis like MRP-II. In this way, the financial planning system will continuously receive information from the manufacturing process, analysis system, and cross-functional subsystems, so that decisions can be made accurately and quickly. Production management will give managers greater strength based on integrated management-level transaction processing. Ability to control in the event, such as timely rolling of the plan, ensuring the smooth execution of the plan, and monitoring the manufacturing process through the financial system. ERP's computer technology requirements are mainly software, which requires a graphical user interface (GUI), a relational database structure, a client / server architecture, object-oriented technology, openness and portability, a fourth-generation language (4GL), and CASE tools, etc. This is a revolutionary improvement to the traditional MRP-II system. Therefore, people call MRP to MRP-II a functional and technical development, and call MRP-II to ERP a revolution.
GTMRPII GTMRPII Integration of Manufacturing Resource Planning
- GTMRPII integration (GT is Group Technology, group technology), it is mainly aimed at solving the problem of increasing productivity in multi-variety and small-batch production. The basic idea is to use GT to solve the weakness of MRP-II without considering how the work is distributed and grouping by parts or by process. At the same time, the use of MRP-II makes up for the GT's inability to directly meet some practical and important problems in production, and achieves advantages and disadvantages. It is an effective production planning and control system suitable for multi-variety and small-batch production.
CIMS Manufacturing Resource Planning CIMS
- CIMS (Computer Integrated Manufacturing System) was first proposed by Dr. J. Harrington of the United States in 1973. It is a production management model for future manufacturing enterprises. It integrates the isolated islands of automation (MRP-II, CAD / CAM, GT ...) and personnel through computers in the past, so that all business operations of the enterprise can be coordinated with each other, so as to improve the enterprise's competitive environment. Adaptability.
- CIMS computer integrated manufacturing system is based on automation technology, information technology and manufacturing technology. It uses computers and its software to organically integrate various decentralized computer software and hardware required for all production activities in a manufacturing plant. It is a high-efficiency, high-flexibility man-machine manufacturing system for multi-variety, small and medium batch production. It is not just the technical development of MRP-II, but it can be regarded as an extension and integration of its extension function. It is based on MRP-II, using modern computer technology to separate all the "islands" of the enterprise, such as business management, planning, product design, manufacturing, quality management, sales and service, and human, financial, and equipment Concentration of production factors, etc., enables one to play the high efficiency and high quality of automation; on the other hand, it has sufficient flexibility to help management, management, and engineering and technical personnel exert their intelligence, according to changing market needs and enterprises. Business environment, flexible and timely adjustment of the company's product structure and the allocation of various production factors to achieve global optimization,
- Thereby improving the overall quality and competitiveness of the enterprise. Its superiority lies in: First, in terms of engineering design and manufacturing
