Question 2: What is the concept of spare parts Spare parts, spare parts! As if the car before and after the turn signal! Car spare tire which are considered spare parts! Scope!
Question 3: Random spare parts is what mainly refers to the equipment attached to a small parts and things like screws, batteries, ah, different equipment random spare parts are different.
Question 4: How to do a better job of spare parts management! Spare parts reserves are generally minimized but also to have a certain safety reserves, I think you can according to the condition of your equipment, combined with their own daily consumption of equipment spare parts and other data to determine the specific can be:Inventory management of equipment spare parts is a complex and detailed work, is an important part of the spare parts management work. Manufacturing or procurement of spare parts, after the inventory accounting should be in accordance with the procedures and relevant systems of careful preservation, careful maintenance, to ensure the quality of spare parts inventory. Through the issuance of spare parts in stock, the use of dynamic information statistics, analysis, you can find out spare parts during the use of the consumption pattern, and gradually amend the reserve quota, a reasonable reserve of spare parts. At the same time, in a timely manner to deal with the backlog of spare parts, accelerate capital turnover, also has an important role.
1. Spare parts warehousing requirements
Incoming spare parts must be checked and accepted piece by piece.
① warehousing spare parts must be in line with the number of applications and production plans, varieties, specifications;
② to check the certificate of conformity of the parts warehoused, and do the appropriate appearance of the quality of sampling;
③ spare parts warehousing must be filled in by the warehouser warehousing list, and by the custodian of the verification;
Spare parts warehousing on the shelves should be good oiling, rust maintenance work. Spare parts into the warehouse should be registered in a timely manner, hung on the label (or card), and according to the purpose (use object) categorized storage.
2. spare parts storage requirements
① storage of spare parts to be stored by the treasurer to save, maintain good, not lost, not damaged, not deformed and deteriorated, clear accounts, neatly placed (three clear, two Qi, three consistent, four positioning, five five yard).
② regular oiling, storage and inspection.
③ Regular inventory, reflect the dynamics of spare parts to the relevant personnel at any time.
3. Requirements for the issuance of spare parts
① The issuance of spare parts must be based on the receipt. For different spare parts, inside and outside the plant to draw up the corresponding methods of collocation and approval procedures.
② lead out of the spare parts to handle the corresponding financial procedures.

④ have recycling value of spare parts, to be replaced with new and old, and develop appropriate management methods.
4. spare parts processing requirements
① due to the transfer of equipment, transformation, scrapping or other objective reasons caused by the enterprise has no need for spare parts, in a timely manner, according to the requirements of the sale and processing;
② due to drawings, process technology errors or poor storage of spare parts caused by waste, to identify the reasons for the proposed precautions and treatment, and report to the competent leadership for approval.
③ scrapping or transfer of spare parts must be in accordance with the requirements of the procedures.
Calculation of spare parts reserve quota
(1) The significance of the formula for calculating the spare parts reserve quota
What spare parts are often stocked depends on the service life of the spare parts, and how much to stock up depends on the consumption of spare parts, and the enterprise's maintenance capacity and supply cycle. Determine the spare parts reserve quota, should meet the needs of equipment maintenance, to ensure production and not backlog of spare parts funds, shorten the reserve cycle as a principle. Generally can be calculated according to the following formula.
Because the service life of the parts (c) is not easy to grasp, generally replaced by the actual consumption (m).
That is: m = e/ c
So that the above formula can be changed to: d = k?m?z
In the formula, the average service life of spare parts (c) refers to the same kind of individual spare parts from the beginning of the use of the average service life of the time can not be used until the end of the time to the month. Calculation of the value of c requires continuous accumulation of the actual consumption of spare parts and close integration with the actual situation of the enterprise. Spare parts ownership (e) is the number of spare parts of the same kind installed in all production equipment of this enterprise (not the number of inventory).
Ownership of homemade spare parts = the number of the same homemade spare parts installed in a single piece of equipment × the number of units of the same type of equipment
Ownership of purchased spare parts = the number of single units counted in the equipment spare parts card or instruction manuals, etc. × the number of units of the same type of equipment
Consumption of spare parts (m) refers to the number of the same kind of spare parts actually consumed within a certain period of time, and can be used to replace the theoretical consumption with the average consumption of the actual overhaul cycle. Theoretical consumption can be replaced by the actual average consumption of an overhaul cycle.
The supply cycle (z) refers to the time required from the application to the finished product in the warehouse for homemade spare parts, and from the application to the arrival of purchased spare parts in the warehouse for outsourced spare parts.
The coefficient (k) according to the enterprise's equipment management and maintenance level, spare parts manufacturing capacity and manufacturing level, regional supply and collaboration conditions, etc. to determine the conditions of good with a small number, poor conditions with a large number.
(2) self-made spare parts maximum and minimum reserves and ordering point determination
Minimum (low) parts reserves d min is the minimum reserve limit of spare parts, that is, spare parts supply cycle due to the conditions of the limitations of the reserves

Question 5: What is the meaning of the list of spare parts in the tender Upstairs is not right, not perishable goods is perishable, such as your equipment in use only may have problems must be replaced on site then it is the spare parts, that is, spare some parts. Of course, not that consumables.

However, suppliers under this approach should be restricted.
Question 9: What is spare parts? This spare parts is the production process is easy to damage the spare parts of the zero part of each other, generally can not wait until after the destruction of the buy, that will affect the production, so they are first prepared, there is damage can be replaced immediately. Such as: equipment with the motor, you can buy two, one with a spare, the spare that can be used as spare parts accounting, and then the spare car tires, such as transportation companies, is also a spare part.
