In the management of spare parts for packaging and printing machinery, the A•B•C management method for the maintenance of spare parts is an effective method in equipment management. In the past two years, we have used this method to implement spare parts management, which has achieved good economic effects for ensuring the maintenance of equipment, improving the reliability, maintainability and economy of the equipment.
The application of A•B•C classification control method in spare parts management is based on the characteristics of spare parts, large capital, and various spare parts inventory time and price difference. The classification principle of A•B•C classification control method is adopted. And the implementation of inventory management methods. For different types and different characteristics of spare parts, different inventory control should be adopted. Another basis for these classifications is also derived from the specific conditions of the actual maintenance of the equipment and the actual utilization of the equipment. Therefore, the original record of equipment operation, maintenance and maintenance is an important basis for the classification of spare parts. It is necessary for the operators and professional maintenance personnel of the machine to do the accounting and recording in this respect according to the specifications.
The characteristics of Class A spare parts are generally spare parts with long reserve period (slow turnover rate), high degree of importance, fewer spare parts, and more difficult procurement and higher prices. Some equipments (ie, high-priority parts) cannot be stored in whole parts, but they can be restored through repair processing. For parts of this nature, we also include the scope of Class A spare parts. However, the solution to its repair and the problems related to external processing must be thoroughly analyzed and processed, so that once the parts need to be repaired, the repair process can be completed within a predetermined time. In short, for the A-type spare parts to be controlled, the order should be ordered and purchased or processed according to the most economical and reasonable use requirements and time to ensure the normal production requirements.
The control of Class B spare parts is not as strict as that of Class A. The order quantity can be appropriately increased, the time can be slightly changed, and the inventory quantity can be controlled slightly wider than the A type. As for the C-type materials, because the consumption is not too large and the variety is more, often in order to simplify the material management, the order can be ordered once according to the planned demand, or the order interval can be appropriately extended to reduce the order quantity. Some items can be stored at zero, for example, in a short period of time, they do not affect the use of repairs, electrical components that can be purchased locally, standard parts of hardware, and so on. The zero inventory of such spare parts can push the funds occupied by the inventory to the supplier, thereby reducing the occupation of spare parts inventory in the enterprise. Of course, for the spare parts that realize zero inventory, the demand quantity, specifications, and demand rules, etc., the spare parts library should be accurately grasped, and relevant information and information should be kept for reference, so as to be accurate and correct, and the reserve funds of the spare parts library can be compressed. To the lowest level of reasonable supply.
There are hundreds of different spare parts in the spare parts warehouse. In the implementation of the A•B•C classification management method, timely feedback is essential. Therefore, the management personnel of the spare parts warehouse should pay attention to the relevant departments to feedback this information. The feedback of such information generally has the following two aspects:
1. Information feedback on minimum reserves: Each spare part must have a minimum reserve. When the stock falls to the minimum reserve, this information should be promptly fed back. Based on this information, the spare parts plan is proposed according to the maximum reserve amount. Order or manufacture spare parts. According to the variety of maximum reserve and minimum reserve, the information will be stored, and a spare parts plan will be proposed after a certain period of time to reduce the inventory funds.
2. Spare parts storage information feedback: After the spare parts are put into storage, this information should be promptly fed back to the relevant personnel so that they can master the spare parts plan, the implementation of the use, and the reference for the implementation of the repair plan. Mastering is especially important.
The above-mentioned various spare parts classification management and information feedback are calculated and managed, so that the supply and demand information can be inquired and provided in time, and measures can be taken in time to realize the economical rational reserve and accurate use of the repair spare parts under the premise of ensuring supply. In the past two years, our factory has achieved good results through this practice.
