Abstract: This paper analyzes the popularization and application of MRPII more elaborated the basic relations and business management to fully understand this basic relationship, to further enhance the level of MRPII application in China and application efficiency, accelerate the modernization of business management are very useful.
A lot of practice that promote the use of MRPII fundamental purpose is to study, research and application of advanced management ideas and methods, based on further changes in our business has long been commonly used traditional and extensive management mode, which enables enterprises to deepen reform and strengthening of enterprise management process, and gradually establish a socialist market economic system in line with our modern enterprise management mode of production, thereby improving management level and economic efficiency, rather than a simple MRPII software selection and implementation process, or enterprise management information and process integration. This, we should have a correct understanding of ideas and unity.
As we all know, MRPII as an effective world manufacturing management information system, which is an essential feature of a variety of management information enterprise in accordance with objective laws to implement highly integrated and rapid processing, production and management for enterprise management and scientific decision-making large, effective information. However, we should see the different management information to reflect the different methods of production and operation management, production organization and business processes. An information is accurate and effective, it really reflects the production and operation management process, or manufacturing process of the objective law, will be directly related to the project's success or failure of MRPII and can play a truly effective planning and control of enterprise business effect. Therefore, promote the use of MRPII, the establishment of enterprise management information system, the overall efficiency up to get the basic conditions for the system should be the accuracy and effectiveness. This requires us to survey the entire project, selection and implementation process, the first to correctly understand and deal with MRPII and business management and management information MRPII and the close integration between the issues, attaches great importance to modern business management ideas and methods of research and application work, good at analyzing and solving the existing production and management problems that exist, the only way to fundamentally improve the level of our application of MRPII and application efficiency, accelerate the modernization of enterprise management and information process.
Currently, most have been applied, is applied and preparing applications MRPII business that use them as long as MRPII software; information can be integrated and expedited processing; to replace manual operation and convenient query; stocks and funds used to come down; to solve manual can not solve the problem in the past; to improve efficiency and achieve the desired objectives and that to make good use of the MRPII system. Obviously, this idea is incomplete. Because, to do this, just the first step towards good use of MRPII. In contrast, some companies in the long-term application of MRPII has been recognized in practice, in order to make good use of MRPII system, first of all to advance or synchronization of modern business management thinking, methods and management information for accuracy and effectiveness, and their organic combine the experience and methods is worth learning and reference.
Here, we promote the use of MRPII some of the problems arising in the process to be discussed to further illustrate the MRPII and business management and management information MRPII and close integration between the problems.
Question one: a company of raw materials and products inventories, the amount of funds used more, as long as the establishment of enterprises that MRPII systems, inventory and capital spending will fall significantly.
Analysis: the establishment of enterprise management information system, the use of MRPII ideas and methods can help to varying degrees, some companies reduce inventory, reduce amount of funds used, but to solve this problem should be a concrete analysis of concrete problems. On enterprises, the main reason this problem occurs not on the enterprise production planning, procurement of raw materials in the products, fixed and organic unity of these links and to implement effective planning and control. Means that the enterprise is now under orders to organize production, and procurement of raw materials and products are used in fixed order point method, the two methods is clearly the goal is not entirely consistent. In addition, the enterprise inventory management than the current confusion, the account book is unclear, arbitrary large purchases of raw materials, the main component suppliers are often tardy delivery, is one of the reasons for these problems. Therefore, an effective way to solve this problem should be the business use of MRPII to determine the demand for raw materials, time and demand, and then combined with the supply of domestic and foreign markets and raw materials production and management of the enterprises themselves to finalize the procurement lead time of raw materials, the best order quantity and fixed in the products, but also strengthen the company's warehouse management.
Thus, MRPII system can prompt the demand for business-to-time and demand for raw materials, it is important. But it can not automatically generate funds used with the inventory and also has a direct relationship between the size of the raw material procurement lead time, the best order quantity and fixed in the product information. The information needs of managers in the full business goals, production planning, financial status, such as procurement of raw materials on the basis of the analysis, sorting and manually enter the MRPII system, not by the MRPII system runs to get.
Problem 2: a business survey in the MRPII project approval stage, raised molding process resistance should be placed on the department to complete the more appropriate, MRPII how to solve this problem.
Analysis: In fact MRPII is an enterprise management information system, it does not shape the process of resistance should be placed on the department to complete such a class of problems. But as enterprises, in preparation for the establishment of enterprise management information system on these issues is of great significance. Because this work on which department they going to complete, more or less all reasonable and business logistics, business process, organization of production, distribution and Solve the work efficiency has a direct relationship. Scientific and reasonable solution to this problem, not only reflects an enterprise's management level, but also reflects the application of MRPII business awareness and understanding of the problem. For example: you put on the warehouse to complete the work, then you can work according to production plans and materials list will be resistance and other electronic components package sent to the plant production lines, both to reduce intermediate links, and easy to manage, but also improve efficiency, flow of materials in a reasonable state. If you put on the workshop to complete the work, then after the completion of either a temporary workshop, to be led to other electronic components and then sent to the workshop production line package; or returned to warehouse and then sent to the workshop complete production line. Obviously, this method will increase in the management of intermediate links, increase the number of workload and unnecessary troubles, so that flow of material in a reasonable state. In addition, you can contract manufacturing to complete the work. Batch size is also visible directly purchase semi-finished products storage.
However, in the MRPII system, when implemented, to address these issues is very convenient. You can put this work on the warehouse to complete, after forming the resistance of the replacement of a code re-storage. If you put on the workshop to complete the work, then just set the processing line and working procedures as you can. In addition, you can contract manufacturing to complete the work. However, no matter which approach you use, the information obtained is not the same. MRPII systems in the implementation process, if a message does not reflect a business process or parts processing and assembly process of the objective laws, even if the management information system can quickly deal with a high degree of integration and its significance and role of make?
Question 3: an enterprise in a single product (major equipment), an international bidding competition, due to poor business management infrastructure, management information is not accurate, not timely, so the prices can not truly reflect the corporate design and production management level ultimately lead to failed in the competition. Since then, the company wanted to build MRPII system to solve the problem the product offer.
Analysis: Typically, a certain competitiveness and adaptability of the product quotation system shall be determined by the following two conditions. First, there is a direct relationship with the products offer enterprise marketing, design, technology, planning, production, workshop, finance, procurement, quality, equipment and labor sectors, must work together, scientific analysis and careful planning. Second, enterprises should have a management information system and management information must be accurate, effective and timely. MRPII as an enterprise management information system, the process of the product offer, no doubt to help business-to-BOM, product delivery, production planning, product cost, financing, raw materials procurement and product quality, fast, dynamic and multi- simulation program for the product quotation system competitive and responsiveness to provide the necessary means and tools. However, the enterprise management infrastructure as poor and between different departments can not effectively coordinated, quotation system required a lot of management information, such as: product design and design changes; materials list; inventory information; of content standards; production load and productivity; raw materials procurement and cost accounting are all with extensive management, rule of thumb estimates obtained, neither accurate nor timely, can not be comprehensive, scientific and reasonable reflection of business management product design and production level and conditions Obviously, this quotation system itself is a certain lack of competitiveness and responsiveness. Also, there was not yet established enterprise management information system, customer needs can not be multi-program fast simulation. Thus, while companies struggled, put a lot more than ten people, and repeated the analysis and comparison, but the reasons given above, ultimately leading enterprises in the fierce international market competition, the situation appears lost.
Thus, an enterprise's survival and development depends to some extent, product design and production of the enterprise management level, management information systems and tools as a means to play a supporting role while the product quotation system is no exception.
In summary, the majority of enterprises in the MRPII project research, selection and implementation process, not the MRPII, MRPII software and enterprise management modernization equated that purchased the MRPII software, business management on the modernized, but should first In the study, research and application of modern business management ideas and methods, industrial engineering, manufacturing technology and information technology, advanced science and technology, based on the management of their own thinking, management methods, management system, management infrastructure, management systems, business process, basic data and product design has a comprehensive, in-depth diagnosis, analysis, improve and enhance the search for restricted business survival and development bottleneck, clearly the system objectives and system requirements, and thus regulate the accurate and effective management information. In this way, we will be able to MRPII closely integrated with enterprise management, enterprise applications for our MRPII and other management techniques, application, and applications to improve efficiency, accelerate the modernization of enterprise management to lay a solid foundation.
