What is the difference between the requirements check function and the anti-check material list

Answer:

Is the top selling products in product structure, its demand is determined by the market or customer orders, that is to say, is determined by the external factors, known as "independent demand". , constitute the sales of the products of various spare parts, fittings, such as blank, raw material in the product structure at the top of the layers of the following materials, their demand is determined by the sales of the products demand, referred to as the "needs". Some materials have the dual nature, such as certain parts can be installed on the product, also can serve as spare parts to be sold directly.

The first is the relevance of the material, and any material is always present because of a need; There is no need for materials without requirements. The second is the liquidity of the material, since there is demand, the material always flows from the supply side. The correlation of materials determines the liquidity of the material. Finally, the material is valuable, on the one hand it occupies the capital, in order to accelerate the turnover of funds, the material flow should be accelerated. , on the other hand, in the process of material form and change of flow, with innovation competition () is not only reduce the price competition, improve the technology content and added value of material, with minimal cost, the shortest cycle, best service, to provide customers the best value and bring their own corresponding profits. This is where the value added chain means. Three properties interact and influence each other. Understanding the management characteristics of materials can help to understand the characteristics of material requirements management. Material requirement types in terms of manufacturing, due to the material requirements according to different sources, MRP Ⅱ system divides into the material "independent requirements (independent demand)" and "related requirements (dependent demand)" two kinds big. This is the first of the material requirements planning (MRP) founders, Dr. Joseph a. rlicky, an expert at IBM, in 1965.

Visible, as long as good management independent requirements (sales product requirements), all the rest of the material requirements planning can be according to the product structure or material list according to the MRP operation logic. Bom is the indispensable important information management system of manufacturing management files, if the lack of MRP software support, it's difficult to build complex product bom. This means that advanced management ideas and methods require the support of information technology. ?? Material requirement management of the three main treatment process according to the thought of supply chain management, demand management is a kind of system management, sum up three process, namely: understanding requirements, access requirements, assurance requirements. The first two processes are primarily processing "independent requirements"; The latter process mainly deals with "related requirements". The three processes are intrinsically linked, and both require the support of the information technology.

Usually, market analysis is to point to locate and estimate of future sales action, including the forecast to the development of technology and products, open up new markets or increase the market share, create demand, find new sources of growth. And sales analysis refers to the analysis of the existing sales behavior, where online analysis processing (OLAP) technology will play an important role. For example, when the enterprise discovery a product sales fell, must find out exactly where even which concrete city, what kind of sales channels, what kind of products; What is the difference between product performance, quality, price and service? It has the effect of time and season fluctuations. Only with detailed, detailed and real-time information can we make the right decision in time. Sometimes, just improving the after-sales service can make sales significantly higher.

Understanding requirements refers to market analysis, sales analysis, and long-term partnership with customers. Understanding the demand side, the traditional MRP Ⅱ system, because it is geared to the needs of enterprise internal, also limited to a passive posture of the waiting for customers to come to accept the order, the more intense market competition environment is not enough. A strong marketing team must be established to take the initiative. Establish a "competitive intelligence network", "spy" on the needs of various industries, regions and customers. Here, the government provide information services for the enterprise is very necessary, enterprises pay the tax, the duties, it shall have the right to enjoy free necessary demand and the development of information industry and region, for the fair competition.
