Managers are often in a dilemma situation, on the one hand it is possible to stop the loss, on the other hand is the high cost of spare parts inventory and spare parts to manage many types, a huge number. As the management is not standardized, spare parts out of storage lack of accurate statistical data analysis, often leading to procurement of spare parts and inventory is difficult to grasp the scale, resulting in inventory, working capital intensive, and for the purpose of ensuring the preparation of future maintenance needs parts planning, and often with a certain blindness. Procurement of spare parts to the low utilization rate of capital turnover spare slow, not more than three years in many companies with spare parts warehouse abound. Spare some large-scale domestic enterprises sometimes scrapped, as many as a billion dollars, an enormous waste of resources and money!The pace of development in the enterprise continues to accelerate modernization , spare parts management also requires continuous improvement , and spare parts management itself , involves a lot of links and departments , managers need to consider the technical management of spare parts , program management , inventory management and economic management of the four content areas . Detailed expanded, it also involves the consumption of spare parts to grasp the law ; inventory forms ; spare parts planning and execution ; procurement of spare parts , manufacture and repair old ; spare parts warehouse management ; economic management and evaluation design of spare parts ; social division of labor background spare parts management innovation, and management information , such as under - a series of problems .In recent years, many companies spare parts management, spare parts management has been in a lot of good practice and innovation to explore and experience, such as what work should be done in the end , in the end what kind of work should include the corresponding workflow how to design, etc. Definition of spare parts managementEquipment, spare parts management is an important indicator of the level of enterprise technology management , cost control is essential for the repair , spare parts and reasonable reserves conducive to the normal operation of equipment, limited excess reserves will cause a backlog of maintenance funds , too little spare reserves will affect production. For many companies, spare parts management has always been a headache problem , because inconsistencies enterprise device type, device ownership , conditions of use , regional collaboration and supply capabilities and the ability to repair capabilities , leading enterprises to determine the reserves of spare parts varieties, it is also not the same number of reserves , many companies spares work - caught on the death , a place on the chaos , always in control of scale and reduce spare parts inventory dilemma maintenance risks.Spare parts management is to be able to proceed as planned equipment maintenance, minimize downtime and reduce repair costs ; is to ensure the quality and quantity of spare parts varieties under supply timely , guided by the principles of economic rationality , spare parts planning, manufacturing, procurement , management of reserves , supply of work carried out . In fact , the whole process is the spare parts management is damaged law , the law ordered the gradual transparency in the library structure gradual economic rationalization process.Spare parts management purposes(1) to ensure normal operation of equipment .(2)strengthening the parts planning and quality management, improve the hit rate plan , put in place to ensure that spare parts according to demand .(3) to prevent substandard spare parts into the plant , to eliminate problems caused by the quality of maintenance spare parts or production delay can not be normal .(4)to meet the needs of production and equipment maintenance .In a nutshell, spare parts management is sufficient to achieve the following objectives.(1)help to reduce production downtime losses caused by the sudden failure of equipment to a minimum. (2) help to reduce equipment down time planned repairs and repair costs to a degree.(3) contribute to the reserve fund spare parts compressed to the lowest level reasonably supply.(4)the consumption of spare parts and inventory forms.Spare Parts ManagementTechnical management of spare parts , spare parts , also known as quota management , including preparation , basic data accumulated spare parts management , pursuant to grasp demand for spare parts , spare parts consumption forecast fixed , determine a reasonable reserve quota and forms Spare Parts for spare parts production, purchasing, inventory provides scientific and rational basis. Technical management of spare parts , the first thing to do is to implement parts consumption quota, determined reserve quota , it is necessary to do everything possible to reduce the consumption of spare parts and storage , but also according to production plans , equipment operation and changes in the external environment, timely and appropriate manner adjust the corresponding consumption and reserves , and therefore the focus of the work is to specify the technical management of spare parts for a reasonable reserve quota .Spare parts consumption is the basis of fixed quota management, consumption of fixed consumption rate is that it is directly related to the amount of reserves and ordering spare parts to determine the amount, the unit is usually pieces / month.Parts of the equipment during operation ever wear, when to wear to a certain extent though cant be repaired or repairable but economically viable , only to scrap the replacement process , known as zero ( the Department) of consumption. Since most of the spare parts are designed in accordance with equal strength rather than by design, such as life, that is, its working life is different, and therefore scrapped , the replacement will have priority, consumption speed is different. The consumption of spare parts is fixed under certain conditions, the production per unit of output per unit of production or consumption of a reasonable number of standard spare parts , such as the consumption of spare funds yuan output value, where said certain conditions , a variety of direct impact on the consumption of fixed factors such as quality of management , business management conditions, natural environmental conditions , production technology and quality equipment , spare parts disappear when determining quota should consider the impact of these factors.Inventory Form Type(1) to determine the type of demand storage model ( the normal supply of inventory models,inventory model with secure storage volume, may be a shortage of inventory models.(2) the probability of the type of demand storage model(3) spare parts storage model cycle method(4)Spare profit method storage modelSpare ABC management:ABC Classification Management Act, also known as the focus of management method is the application of materials management in the ABC classification of controlled spare parts management. The approach by focusing on the major forces , targeted , focused to catch the main contradiction , that the difference between primary and secondary, category management is a small effort to obtain a large effect an effective management techniques. Application ABC management method that can solve complex management of spare parts and a relatively small staff of vast contradictions, can play a multiplier effect, not only to better ensure the supply of production and maintenance needs, but also significantly reduce reserves, accelerate cash flow. This method is the first to be classified for spare parts, and then press the class adopted different tactics for management, which is currently the most commonly used as a spare parts business category management approach.Generally. Spare parts inventory supplies many types of businesses. Every species do not ask the price, and the stock quantity is not so much variety and some spare parts , but of great value , but spares many varieties but value is not high , due to limited corporate human resources and funding , therefore, spare parts inventory for all varieties are given relative degree of attention and ask management is unrealistic. In order to make a limited time , money , manpower, material and other corporate resources can be used more effectively respond to classify inventory of spare parts , spare parts inventory that is based on different degrees of importance , respectively, different management , which is the basic idea of the ABC classification .3A spare parts management model The idea is to consider the subject highlights the lack of spare parts may be adversely affected due to the production and safety , and to reduce the risk as much as possible , on this basis , which takes into account the size of the level of spare parts inventory control , first consider the spare key itself ( damage to the consequences : impact on production , equipment, safety and environmental impact , etc.) ; Second, considering the fragile nature of the spare parts (load , position, role , etc. )Spares Program Management Program management is a comprehensive spare parts, spare parts, and comprehensive management of enterprises according to maintenance plans and technical measures, equipment, such as project planning, preparation of a good spare after Bian purchase plan, information on various aspects of how to effectively monitor and adjust. spare program management is the core content.Spare parts program management task is fixed on the basis of Spare Parts , spare parts supply plan preparation , and the supply of spare parts inventory and monitoring both the information to make the actual inventory of spare parts are always in the reserve quota Van Quarters changes in order to achieve both to ensure production and maintenance needs, without the backlog of waste purposes.Spare Gao effective program management to ensure to the maximum extent normal operation of equipment, spare parts planning and strengthening quality management, improve the hit rate plan, fully guaranteed spare parts demand in place. Meanwhile, to prevent substandard spare parts into the plant , to eliminate problems caused by the quality of maintenance spare parts or production delay cant be normal , spare parts management program also has an important significance.Spare program management processesSpare program management generally refers to begin ordering and manufacturing spare parts made plans to work up until the spare parts warehousing inches between this period. General use by the grass-roots demand for spare parts department planning, management functions combine research situation , according to the companys overall goal of cost control , reference the actual demand for spare parts of a cycle , make a reasonable analysis, thus forming an optimized inventory model for summary and partial adjustment , the Executive spares procurement plan. As can be seen from the above processes , focusing mainly spare parts management plan including the preparation and organization of the implementation plan of spare parts , including how to rational analysis prepared by parts planning is particularly important.In the working node spare parts program management, the functions of the departments generally related to the device, the Purchasing Department ( materials center ) and secondary use of the unit .Procurement and manufacturing of spare partsRegardless of which party and in terms of procurement of spare parts are manufacturers of spare parts inventory management - an important issue is the responsible sourcing of materials obtained on-site maintenance, spare parts and supplies required services. Typically, the cost of maintenance services business for more than 60 % of the parts from the spare parts and materials purchased. Therefore, the management of business-to- Bian has a considerable share of attention. Most large companies have a special material procurement centers and other departments. The importance is not limited to the procurement of spare parts purchased spare parts cost control, quality spare parts supply services, as well as spare parts or services submitted to the timing on these two aspects are likely to have a significant impact on equipment maintenance.Enterprises in the procurement of spare parts management interface is mainly good purchase , purchase processes of co- Bian withered , value and cost analysis carried spare parts , consideration is purchased or homemade , of which take the form of purchasing , preparing purchase orders, as well as to determine the purchase price , etc. ; the same time , for the selection of suppliers of spare parts , spare parts supply contracts and procurement to ask other aspects of quality assurance should be standardized management.Spare Parts Warehouse ManagementSpare parts inventory management is the acceptance of storage, the correct distribution, science custody spare parts and so on. It is a complex yet delicate work, but also an important part of spare parts management. Reserves in the form of spare parts: Due to different production scale of enterprises and production management systems, spare parts and inventory conditions of nature reserves in the form of spare parts will also be different, each enterprise should be quiet conditions and their actual conditions, the flexibility to choose their own form of reserves.1, finished reservesThis is the most common, the most common form of reserves. Without further processing when those spare parts has been finalized, can be made (or purchased ) spare parts stockpiling , use and assembly. Such spare parts are usually interchangeable.2, semi- reserves3, rough ReservesTo reduce downtime repair time , for some small parts machining work , but difficult to determine in advance the size of the processing must be repaired by fitting the dimensions to determine the size of the processing prior to use , can be bad form in terms of gross reserves .4, pairs (sets) Reserves5, parts assembly reserves.Spare parts warehouse set upThe basic principles of inventory management: a clear spare storage location; spare set- effectively ; accurate records of spare parts transaction.6S spare parts warehouse management and visualizationThe main purpose of warehouse management is to ensure that when it is time to meet the equipment needs to be able to provide the required quality of service requirements for spare parts, modern warehouse management also requires clean and orderly while maintaining the warehouse, the constant pursuit of efficient spare parts management, and therefore, 6S and visual management, should also be good to play a role in the management of spare parts warehouse.6S: organize, straighten, sweep, clean, safe and literacy.The so-called visual managemen , also known as visual management , through visual means lead to changes in peoples consciousness , so as to achieve management objectives - ways . In peoples daily activities and work, we always through the five senses ( sight, smell , hearing, touch, taste ) to perceive things. Wherein more than 60% of the action from the vision Start perception by the visual prompt conducted . Flash this , in advancing the process of enterprise management , we should make full use of visual effect , so that requirements, state , methods , processes , rules with visible way to convey to each employee , so that employees easy to understand and easy to comply with , easy comparison , easy to accept , so that information at a glance , so that the estimated interest rates repeatedly to form the impression among employees reached memory , while achieving motivation, morale goal.Spare economic managementSpare funds belonging to corporate liquidity, how to react rationality spare funds used to ensure liquidity in equipment maintenance needs, based on the reduced spare parts inventory, improve cash flow of spare parts Spare economic management is outstanding issues. Spare economic management of content including accounting and assessment work funds.Spare fund managementStrengthening financial management is the use of the form of value, through accounting, afterwards, reimbursement, etc. by means of accounts, accounting and analysis of the economic activity in the circulation process of financial revenues and expenditures, it reflects the economic process and its outcomes supervision, the flow of spare parts service for enterprises for the companys overall business efficiency indicators services. Spare reserve funds for the purchase and storage of corporate spare parts, spare parts management and the general term used to fund related work. Starting from the procurement of spare parts payments to transit, warehousing inspection, storage, purchase spare parts for freight until the recipients of this process occurred library, storage fees belong to spare reserve funds. Even including all levels of the warehouse, the establishment of special warehouse operating costs and maintain the safety of inventory related costs can be broken down intoEarly investment cost of reservesSpare parts inventory management costs.Spare parts management innovation and social operationSpare parts procurement model innovation : Many companies mention of spare parts management , spare parts inventory management is the guiding ideology , this is
