【正文】 B products are middle of the stock value of these species 30% of the total inventory value of the total value of 15% to 25%。s warehouse management, distribution of cargo spaces You are also a number of principles: (1) FIFO principle, Ji is the ancestor of goods, firstout library library principles, the principles generally applicable to a short life cycle of goods. (2) the principle of facing channel, referring to the goods of the mark, name the face of passageways so that the operator can easily simple identification, it allows the retention of goods, access to easy and efficient manner, which is to the warehouse to be fluent in the basic principles of operation. (3) weight characteristics of the principle, meaning that according to the weight of different goods to determine the level of goods in the storage location of places. In general, the weight should be kept on the ground or the lower shelf position, light goods were kept in the upper shelf location. In the case of manual handling operations carried out when the people of waist height for the custody of heavy or large items, while above the waist height of the light used to keep the goods or small items. This principle, the use of the safety and shelf manual handling operations have great significance. According to this principle, the pany39。s warehouse storage rack management approach is used in positioning guidelines to follow. Positioning refers to each type of storage or storage of goods are fixed for each cargo space, cargo space of goods can not be interoperable. Therefore, when planning cargo space, cargo space for each volume of goods shall not be less than the possible maximum amount in the bank. However, in actual operation, the positioning of different storage conditions generally done in accordance with appropriate adjustments, it will make changes based on the actual situation. Cargo space in the warehouse management in the work by the staff of the pany, bining theory with practice, carried out positioning, fixedpoint, quantitative management principles, therefore, Ta cargobit capability is not Quanbu Anzhaozuida conducted in the library volume positioning, as the pany39。 the potential use of space accounted for 10%。s warehouse space layout is stored on the shelves of goods, threedimensional space utilization is not high, so he39。s supply chain, logistics, warehousing and distribution systems and customer service system. The pany is headquartered Total finished goods warehouse 3, namely a set of finished products warehouse, finished products and finished second group of three storage warehouses. They are based on different types of products in different product subwarehouses: one product a warehouse on the first floor is to facilitate the shipment into, so it is relatively types of goods stored there are more point, such as lamp, lamp panel and so on. And all of the export goods are stored in a group. Finished second group is mainly warehouse track lights, metal halide lamp, T4 lamp, T5 lamp and light. The pany39。附錄英文資料原文：From the perspective of modern logistics systems, storage is an important part of logistics is the logistics system, distribution center, hoping for effective logistics warehouse here, scientific management and control, so that the logistics system more smoothly, more reasonable to run. In this paper, the importance of starting from the warehouse, bining theory and practice, through an enterprise storage and logistics activities in the space and cargo space to analyze how the activities in the warehouse through the space and cargo space management to improve storage efficiency, reduce storage costs.
