Implemented mandatory quality standards and environmental regulations constraint intensified as the German TOP Dharma (Topfer Law) on the provisions of the manufacturer and the distributor is responsible for the recycling of packaging materials, will inevitably lead to the return reverse logistics and recycling generation of recycling and reverse logistics. The opposite direction of the traditional supply chain, reverse logistics is to eventually substandard products held by the customer, waste recycle to each node in the supply chain, as shown below. Reverse logistics as an important link in the supply chain, warehouse and assume the functions of the returns management center is responsible for timely and accurate positioning of goods, to notify all relevant aspects and found that the potential value of the returned goods for enterprises to increase extrabudgetary or rescue income; improved returns processing, control deviations that may occur; assessment and ultimately improve the processing performance. Storage and custody functions warehouse space for storage items, and equipped with the appropriate equipment in accordance with the characteristics of the stored items to keep stored items intact. For example: storage warehouse volatile solvents ventilation equipment must be provided to prevent the high content of volatile substances in the air and explode. The warehouse storage precision instruments, need moisture, dust, constant temperature, therefore, should be the establishment of air conditioners, thermostats and other equipment. Job in the warehouse, as well as a basic requirement is to prevent break something when handling and stacking crushed items. Which requires the continuous improvement and perfection, handling equipment and methods of operation of the the warehouse really play the role of storage and safekeeping. 2. Adjust the function of supply and demand to create material time the effectiveness of one of the two basic functions of logistics, the logistics of this function is done from the warehouse of the logistics system. Modern mass production of a variety of forms, each product has different characteristics from the continuous production and consumption point of view, the production of some products is balanced, consumption is not balanced, there are some products is not balanced consumption is balanced constantly. Enable the coordination of production and consumption, which requires warehouses to play a "reservoir" regulatory role. 3. Regulate cargo transport capacity is the the various carriers transport capacity is not the same. Ship transport capacity, ocean shipping is generally ton inland vessels hundreds of tons to thousands of tons. The transport capacity of the train smaller wagons shipment to 30 ~ 60t, a train of cloud amount up thousands of tons. The transport capacity of the car is very small, generally each vehicle fitted ~~ 10t. Transport convergence between them is suffering, the transport capacity of the differences, but also through the warehouse regulation and convergence. Circulation the functional modern warehouse and distribution processing functionality in the process of change by the the safekeeping type flow-the center warehouse storage and custody of the goods to the circulation, sales and the center. Warehouse must have not only the storage and safekeeping of goods equipment, but also to increase the sorting, matching, bundling, distribution processing, information processing settings. In this way, that the expansion of the business scope of the warehouse, improve the comprehensive utilization of the material, and convenient consumption, and improve the quality of service. Information transfer function associated with the change of the above functions, resulting in a warehouse of information transfer requirements. In dealing with the affairs of the warehouse activities, the need to rely on the computers and the Internet, through electronic data interchange (EDI) and barcode technology to improve information transmission speed of warehousing goods, timely and accurate understanding of the warehousing information, such as a warehouse utilization levels, and out of the library's frequency, warehouse transport, customer needs, as well as warehouse personnel configuration. Product lifecycle support functions defined according released in January 2002 by the American Society of Logistics Management, logistics: supply chain operations, in order to meet customer requirements for the purpose of goods, services and information to achieve the output land and sales between high efficiency and low cost of the forward and the ideal reverse flow in the storage plan execution and control process. Visible modern logistics, including products from the "students" to "dead" the entire production, distribution and service of process. Therefore, the storage system to respond to product life-cycle support. Article edit 【Shenzhen the cars checked http://www.sz56gs.net], completed
