Warehousing subsystem 2021-06-20 09:39:43 Commodity storage and custody make the commodity in a relatively long or short state of stagnation during its circulation. This stagnation is completely necessary. Because commodity circulation is a continuous circulation process from decentralization to concentration, and then from concentration to decentralization, and inventory as a kind of 'reserve' is necessary to maintain normal production, maintain continuity, and cope with unexpected needs. Commodities in international trade and transnational operations are collectively transported from manufacturers or supply departments to the port of shipment, and sometimes need to be temporarily stored for a period of time before being shipped for export. This is a process of collection and dispersal. In order to maintain continuous commodity exchanges and meet the requirements of finishing, assembling, reprocessing, repackaging or repacking of export commodities before trade, Guangzhou Logistics must form a certain amount of pre-trade preparation storage; sometimes, due to certain export commodities and perennial production but seasonal For commodities for sexual consumption, a certain amount of seasonal reserves must be reserved. Of course, sometimes there will be some temporary arrivals and the cargo owner can’t leave for a while. What's more serious is that the imported goods arrive at the port or border station, but the cargo owner is not notified or unclaimed. This kind of special temporary storage and custody, namely The so-called phenomenon of suppressing ports and substations. It can be seen that in this case, the international logistics is blocked, and there is a situation of poor logistics, which brings losses to both parties in trade, Hong Kong, and ships. Therefore, it is understandable that the inventory of international goods is often higher than that of domestic trade companies. International cargo transportation overcomes the space distance of the use value of goods, creating the space benefits of logistics, so that the physical location of the goods is transferred from the seller to the buyer; while storage and custody overcomes the time difference in the use value of the goods, and the logistics department relies on storage. Keep the time value of the creation of goods. Commodities in international trade and cross-border operations are generally stored in the warehouse of the manufacturer or in the warehouse of the purchase and supply unit, and when necessary, they are transported to the port warehouse for storage (the time of storage in the port warehouse depends on the port shipment and international transportation operations. Organic connection), and some are stored in international transshipment stations. From the perspective of logistics, inventory is the result of no 'seamless connection' between enterprises or departments. While inventory is used as a reserve, it also exists as a production idle. Therefore, commodities should not stay in the warehouse for a long time, but should minimize the storage time and storage quantity, accelerate the turnover of goods and funds, and realize the efficient operation of international logistics. 1. Loading and Unloading and Handling Subsystem Loading and unloading activities are logistics activities that occur with transportation, storage, processing and other activities. Compared with commodity transportation, the loading, unloading and handling of import and export commodities is a short-distance commodity movement, a link and a bridge between warehouse operations and transportation operations, and the realization of the space benefits of logistics. It is a logistics activity that guarantees the continuity of commodity transportation and storage. Doing a good job in the shipment of goods (checking warehouses, transferring and loading, etc.) is very important to speed up international logistics, and controlling the cost of loading is also an important link in reducing logistics costs. Effectively doing well in loading, unloading and handling operations can reduce the time between transportation and storage. In recent years, the loading, unloading and handling activities of international logistics have become more efficient and more convenient due to the wide application of containers. On the premise of standardized container loading and unloading, port terminal loading and unloading facilities are standardized. It is possible to increase the size and efficiency of loading and unloading operations.
