1, template development basis

Based on the principle of procurement segmentation, as the basis for the development of non-standard parts procurement template. Because, in order to realize the scientific control of procurement price, the supplier must maximize to ensure that the most appropriate quality standard level, price supply production needs, neither can produce high-end products to meet the low-end demand triggered by the excess function of waste, but also does not cause the low-end products can not meet the needs of the frequent replacement, resulting in increased consumption of waste, the implementation of the procurement segmentation is an effective method of controlling the procurement price.

The so-called procurement segmentation refers to the use of ABC classification method will require all spare parts according to the use of parts, equipment, technical level, production process on the technical quality of the product requirements, the quality of the market supply of such products, the price of the situation, as well as on the production, quality, safety and other factors such as the degree of impact on the detailed classification, grading.

For different needs to determine the different quality levels of efficiency of the best products, to take different procurement methods, management and control efforts. Procurement segmentation is a very complex project, but also to achieve the fine management of procurement and supply of spare parts, enhance the efficiency of procurement and supply must do a good job of a basic work [1].

2, the development of the template

In order to effectively control the procurement price of non-standard parts, first of all, according to the form of frequently procured parts structure, the parts structure is divided into six basic categories, namely, shafts, disk sets, brackets and boxes, hexahedrons, fuselage seats and special categories.

In accordance with these classifications, a large amount of data was collected and valued using the tonnage method, i.e., the tonnage price of the parts is δ (million yuan/t), the weight is W (t), and its cost is V (million yuan) obtaining: V = W - δ.

Using this principle, according to the average purchase unit price of each part, as well as processing drawings of the drawing weight, after repeated measurements, comparison, analysis, calculation of the tonnage price of each type of parts, from the material, weight, various technical requirements and tonnage price constitutes the “non-standard processing parts pricing template”.

This template reflects the processing technology program process costs, that is, ① blank or raw material costs; ② production workers wages and additional wages; ③ tools, fixtures costs; ④ equipment maintenance costs; ⑤ equipment depreciation; ⑥ special fixture repair and depreciation; ⑦ adjust the cost of the machine tool; ⑧ workshop expenses; ⑨ enterprise management costs. At the same time is also convenient and efficient to guide the procurement staff to develop a more accurate purchase price.

For example: according to the demand side of the processing drawings provided by the approved accurate spare parts surface weight, in accordance with the template parts structure, materials and technical requirements to find the appropriate classification, and then against the net weight data segment can find the spare parts of the procurement of the tonnage price, and then multiply this price by the net weight (kg), you can calculate the purchase price of the spare parts, and then use the price of the approved supplier's price offer.

1, template control effect on the procurement price

Adhere to ensure that the procurement of product quality and stability, reasonable price of the procurement principle, in the profit control, adhere to the long-term template against the non-standard machining parts procurement price analysis, sorting out, and vice versa on the “non-standard machining parts pricing template” bottoming out, adjustments, and to seek a reasonable profit margin.

Through the “non-standard machining parts pricing template” implementation, in nearly half a year's time, so that the non-standard machining parts of the purchase price down 25% to 30%. Also take the monthly non-standard machining parts procurement price of random sampling method, the template data maintenance.

This work first of all for the “non-standard machined parts pricing template” provides a large amount of data information; secondly, to verify the “non-standard machined parts pricing template” data reliability; again, to improve the procurement staff's business capacity and self-awareness.

At the same time, but also to strengthen and suppliers of technical exchanges, and at any time combined with the market price of raw materials and the same period of the purchase price to adjust the template data accordingly, for example: the beginning of 2007 to June 2008, due to the price increase of raw materials, electricity, labor costs and other price factors, the template data to do the corresponding upward adjustment.

Such as July 2008 due to steel raw material prices by the impact of the global economy gradually fell, through timely and dynamic adjustment of the template data to ensure that the template data is accurate and reliable, so that the purchase price both in the case of fluctuations in market prices to ensure that the quality of the products purchased, but also not to damage the interests of suppliers.

2, the template dynamic adjustment of the implementation of the effect

With the continuous development of enterprises, the level of enterprise equipment is also improving, a lot of high-precision, large size changes, complex shapes, special materials, more and more requirements for spare parts, due to the relatively slow development of non-standard processing enterprises within the territory, the existing processing technology and equipment can not ensure that the eight steel procurement needs, so that non-standard machining parts flow to the market for processing outside the territory.

In order to ensure the quality of commissioned spare parts processing outside of Xinjiang, price control, in the original “non-standard machining parts pricing template” on the basis of the template for dynamic adjustment, completed the “non-standard machining parts pricing template” and “non-standard machining parts pricing template outside of Xinjiang” two templates, which scientifically reflect the two templates within and outside of the Xinjiang region of the technical level of machining, a reasonable reflection of the procurement of non-standard parts inside and outside of the territory of the price of the tonnage. The two templates scientifically reflect the technical level of machining within and outside Xinjiang, and reasonably reflect the procurement tonnage price of non-standard parts within and outside Xinjiang.

3, the template on the procurement of spare parts cost-effective impact

Take the best performance-price ratio of procurement is the best procurement method, “non-standard parts pricing template” as the basis for pricing, in the face of different materials, different configurations, different machining processes, different quality levels and different prices combined with different prices to control the procurement price.
