Large enterprises spare parts classification method is relatively old and not suitable for modern enterprise management. This paper proposes a new three-dimensional categorization method thought, for enterprise cost reduction and efficiency to provide an effective solution. Keywords: spare parts; classification method: three-dimensional classification method Introduction Equipment spare parts management belongs to the scope of enterprise logistics. In large enterprises, the equipment volume is large, complex structure, so the spare parts will be a variety of types and quantities, occupying more liquidity, good management of equipment spare parts logistics has become an important way to reduce costs and increase efficiency of large enterprises. With the progress of industrial technology, spare parts logistics management is gradually getting the attention and understanding of technicians. At the same time, with the rapid development of industrial technology, spare parts logistics management in theory and practice will be more rich and perfect, laying a good foundation for the entire equipment management. According to the equipment maintenance mode of equipment spare parts classification according to the maintenance mode of equipment spare parts can be categorized into accidental parts, planned maintenance parts, consumable parts and so on. Accidental parts mainly refers to the use of equipment spare parts in the event of maintenance mode. Accidental parts are divided into two kinds: one is the standard accidental parts, that is, store shelves everywhere on the equipment spare parts (offtheshelf). This kind of equipment spare parts easy to buy but difficult to predict the replacement cycle, you can try to prepare less or not prepared; another is a special accident parts, mainly refers to some usually can not be replaced and difficult to predict the replacement cycle, and once the damage to the production of more harmful equipment spare parts. For example, the operating table buttons, equipment screws and nuts, proximity switches belong to the standard accident parts, while the pulse encoder proportional valves and other live to belong to the special accident parts. Planned maintenance parts are equipment for preventive maintenance according to plan. According to its operating status to determine a reasonable maintenance cycle for replacement of equipment spare parts is planned maintenance parts, such as cold rolling mill roll bearings is planned maintenance parts consumables, also known as wearing parts, refers to those large quantities of widespread damage irregularities, but also has the conditions for replacement of equipment spare parts. Consumable parts can be quickly replaced in the general inspection and maintenance of equipment spare parts, consumable parts of low technology, consumption, fast turnover, easy procurement, such as power fuses insurance hydraulic sealing rubber are consumable parts. Commonly used ABC inventory classification method of inventory control is currently the most commonly used classification method is ABC classification, also known as the Pareto classification method, the basic idea is to analyze the qualitative and quantitative analysis, the management of the object in accordance with the classification index is divided into three categories of ABC, and then take the corresponding control strategy. In practice, the ABC classification standard is the inventory of equipment spare parts varieties in the annual consumption amount, that is, the product of consumption and unit price. Generally speaking, class A accounted for 5% of the number of varieties of 10%, accounting for 60% of the total amount of annual consumption of 70% of the total amount of equipment spare parts for the class to strive to reduce the backlog of ordering rouge Shenzhen 7., goods batch and safety stock are minimized to prevent stock-outs need to strengthen the inventory supervision. b equipment spare parts accounted for 20% of the total number of varieties of 30% of the total amount of annual consumption of 20% of the total amount of equipment spare parts for such equipment can appropriately increase the order batch, can increase the order quantity, and then take appropriate control strategies. Category C accounted for 50% of the total number of varieties of a 70%, accounting for the annual consumption of less than 15% of the amount of equipment spare parts can be further increased ordering batch and extend the ordering cycle. ABC classification helps to differentiate between the key points, take care of the general, and therefore widely used, however, its shortcomings are also very obvious. The criteria for its discrimination is not comprehensive, only according to the variety, the amount of money is difficult to scientific classification, such as some equipment spare parts, although the amount of money occupied is not large, but the impact on production, and CaiDing hook cycle is longer, obviously should be categorized into class A, but according to the amount of standard may be categorized into class B or C. Improved three-dimensional spare parts inventory classification method due to the limitations of the ABC9, subclass method, here we propose a three-dimensional classification method of equipment spare parts: according to the characteristics of large-scale enterprise equipment spare parts, you can consider from the degree of importance of the production, how much money to occupy the situation and the procurement and transportation cycle length of the three-dimensional classification, called the three-dimensional classification of the equipment spare parts method. 1. The importance of spare parts to production. In order to distinguish the priority of equipment spare parts, according to the impact of downtime on production, the ABC classification of equipment, and then the components (components) for the ABC classification, and finally the parts for the ABC classification, this classification method pays more attention to the role of equipment in the production process, focusing on the impact of the equipment downtime on the production, the consequences. (1) the ABC classification of equipment, class A equipment is in the mainstream process, the production of direct impact on the equipment, class B equipment is in the non-mainstream process, but the impact on the production of equipment, such as energy, gas supply equipment, or although in the mainstream process, but does not constitute a great impact on the equipment, etc. Class C equipment is in the non-mainstream process, the impact on the production of the equipment can not wait for the repair of the failure. (2) the ABC classification of components, class A components are the core of the equipment, the main load parts, the production and operation of the equipment directly affects the impact of the impact of important, serious consequences of failure, serious downtime losses. class B components are more important parts of the equipment, failure affects the function of the equipment, product quality, productivity and safety and environmental protection, but does not cause serious downtime losses. class C components are auxiliary parts of the equipment, failure does not affect the function of the equipment, product quality, productivity and safety and environmental protection, but does not cause serious downtime losses. Failure will not have an immediate impact on equipment function, product quality, production efficiency and safety and environmental protection. (3) parts of the ABC classification. class A parts in the core of the components, the main load parts, the production and operation of the equipment directly and important, the consequences of failure is serious, serious downtime losses. class B parts in the more important parts of the components, failure affects the function of the equipment, product quality, production efficiency and safety and environmental protection, but does not cause serious downtime losses. class C parts in the
