Auto Ancillary Companies In The Supply Chain Purchasing On Time And Inventory Studies

With the economic globalization, competition among enterprises has shifted to the supply chain and supply-chain competition. To determine whether an enterprise's competitiveness is not just look at their own strength, but also to integrate their resources. Through effective supply chain operation of the rapid access to markets, reduce inventory risk and cost pressures; rapid response (Quick Response, QR) and the ability to efficiently respond to customers (Efficient Customer Response, ECR) has become the ability of enterprises to survive and develop a decisive factor. In order to meet consumer demand for enterprises to improve the supply chain, such as the bullwhip effect, should be committed to continuous supply chain co-operation between enterprises and improve supply chain flexibility.The dissertation focused on the field of research of purchasing and supply of Chinese automotive industry. It transplanted the philosophy of just-in-time system to the operations of logistics of inter-corporations and practices just-in-time purchasing tactics n order to reduce the overall cost of supply chain run and speed up the response to the customers'needs.First of all, the first section of the article, the article raised the topic of the background and significance of supply chain management is the key to the corporate chain coordination and cooperation in the supply chain through the various links, at least to a certain degree of cooperation than their respective To operate independently to achieve greater income, that is, in every link of the supply chain through the entire supply chain as a whole to deal with its own chain in the relationship between the ability to obtain the maximum benefits system, for the avoidance of the principle of self-serving most of the times Optimization. As a result, use of scientific methods to manage these stocks in order to maintain a minimum level of great significance, "Stock coordination" is considered the impact of supply chain efficiency one of the key factors. Supply chain management in modern enterprise management occupies an increasingly important position in the supply chain competitive era, if our businesses continue to own the center, and thus to design their own systems, competition in the international market in the inevitable Disadvantage, which requires companies and other related businesses to form the supply chain, have the strength to participate in international competition. As a result, research in supply chain management environment, to develop a scientific and rational inventory of modern enterprise management strategy, an important theoretical and practical significance.Secondly, the second chapter of the relevant documents were read to the theory of the supply chain, inventory theory and the theory expounded on time procurement for the article to lay a solid theoretical foundation. By then large-scale domestic auto OE data collection, describes China's auto manufacturing purchasing and supply situation, combined with the existing supply procurement practices, China's automobile manufacturing industry into the existence of the three procurement methods available. China's major purchases OE and supply analysis of the status quo can be summed up China's major OE supplier of the existing procurement methods can be roughly divided into bulk supply, supply billboards, three synchronous supply.Once again, at home and abroad, through the relevant procurement time reading literature on the characteristics of the procurement on time and on the connotation, and traditions and procurement methods were compared. According to the variant type of parts and components, parts and components such as the size, complexity, as well as different values, different application methods available. Synchronous supply for high value, high complexity and space accounted for large parts, or body color requests so as to a wide variety of parts and components, parts and components as a result of such a wide range and large, warehouse storage space is limited, can not be Host the factory set up a large number of stocks, using production and consumption can only be one, a procurement and distribution of a way to reduce the supply of logistics operating costs. Supply procurement plan for large-volume, value and the small size of small parts, such small changes in the types of parts and components are highly versatile, able to better predict the consumption of parts of the day, allowing suppliers Be able to accurately in accordance with the needs of enterprise customers to schedule production and shipments on a regular basis. Kanban delivery synchronization between suppliers and supplier program, on the one hand, due to the volume of parts and components as well as the magnitude of value is not suitable for large supply plan, on the other hand, due to the transport distance, and other causes to be synchronized easily lead to excessive supply Transportation costs, allow the use of Kanban supply a small amount of stock OE approach requires suppliers Kanban replenishment.Finally, the application of the principle of the bullwhip effect on time to reduce inventory purchases in the role of the bullwhip effect discussed. For the bullwhip effect caused by reasons, as follows from the two-time procurement has played a role in reducing the bullwhip effect:1) on time delivery through the multi-frequency low-volume suppliers to reduce the volume increase in the batch delivery. Multi-frequency low-volume delivery on time is one of the characteristics of the procurement. In order to reduce the frequency of delivery due to the increase in the cost of transport logistics, by third-party logistics companies responsible for all suppliers of parts and components of the transportation and distribution of materials in order to improve transport a full load rate and reduce the overall cost of transport.2) The procurement time through the exchange of data and adequate information sharing to prevent distortion of information in the supply chain.Real-time delivery of accurate information is a prerequisite for suppliers on time. Through information sharing, the lower the demand for information in a short period of time can be transmitted to the upper reaches. The use of Internet technology companies can choose to host the information needs of the company's Web site, the supplier of their particular account of the time agreed to landing, from time to time from the server vendors need to download the information.The article focused on the end of the inspection time for the procurement supply chain suppliers and manufacturers in the OE link request, through case studies put forward in support of China's automotive enterprises procurement on time.After more than content, reached the following conclusions:1. China's auto ancillary companies mainly in bulk supply, delivery and Kanban supply synchronization of the three modes of supply procurement and analysis of its application.2, on time and procurement needs of suppliers and vendors host in partnership to achieve the rapid flow of information and sharing, small-volume, high frequency of delivery.3, supply chain inventory management in the existence of bullwhip effect, the time of procurement can play in alleviating Stock bullwhip effect.4, through the morning of Siping City, the new Factory on time of purchase, in supporting China's automotive enterprises on time procurement made several suggestions.
