Management of wood-based panel, plywood and MDF suppliers – ten principles for development and selection
1、 Ten principles for the development and selection of wood-based panel, plywood and MDF suppliers
- The principle of systematic comprehensiveness: the establishment and use of a comprehensive and systematic evaluation system.
- The principle of simplicity and scientificity: the evaluation and selection steps of wood-based panel plywood and MDF suppliers, and the selection process are transparent, institutionalized and scientific.
- The principle of stable comparability: the evaluation system should operate stably, unify standards and reduce subjective factors.
- The principle of flexibility and operability: the evaluation of wood-based panel, plywood and MDF suppliers in different industries, enterprises, product requirements and different environments should be different, so as to maintain a certain degree of flexibility and operability.
- The principle of door to door: the size and level of wood-based panel plywood and MDF suppliers are comparable to those of purchasers.
- The principle of half proportion: the purchase quantity shall not exceed 50% of the production capacity of the wood-based panel plywood and MDF suppliers, and the wood-based panel plywood and MDF suppliers who supply in full are opposed. If only one family of plywood and MDF suppliers is responsible for 100% supply and 100% cost sharing, the purchaser will have a high risk, because once the plywood and MDF suppliers have problems, according to the development of the “butterfly effect”, it will inevitably affect the normal operation of the entire supply chain. Moreover, when the purchaser is dependent on certain supply materials or products, he should also consider geographical risks.
- The principle of quantity control of supply sources: the number of wood-based panel plywood and MDF suppliers of similar materials is about 2 to 3, and the number of primary and secondary wood-based panel plywood and MDF suppliers is divided. This can reduce the management cost and improve the management effect, and ensure the stability of supply.
- Strategic principle of supply chain: develop strategic cooperation relationship with important wood-based panel plywood and MDF suppliers.
- The principle of learning and updating: the indicators of evaluation, the objects of benchmarking, and the tools and techniques of evaluation need to be constantly updated.
- General principle – comprehensive, specific and objective principle: establish and use a comprehensive comprehensive evaluation index system for wood-based panel plywood and MDF suppliers to make a comprehensive, specific and objective evaluation of wood-based panel plywood and MDF suppliers. The performance, equipment management, human resource development, quality control, cost control, technology development, customer satisfaction, delivery agreement and other aspects of wood-based panel plywood and MDF suppliers that may affect the supply chain cooperation relationship are comprehensively considered.
2、 Main control points of wood-based panel, plywood and MDF supplier evaluation
- Screening and selection conditions of wood-based panel plywood and MDF suppliers.
- Investigation on the quality assurance capability of wood-based panel plywood and MDF suppliers.
- Sample quality identification of wood-based panel plywood and MDF suppliers.
- Determination of evaluation contents and steps of wood-based panel, plywood and MDF suppliers.
- Review and approval of evaluation conclusion of wood-based panel, plywood and MDF suppliers.
- Approval of qualified wood-based panel plywood and MDF suppliers.
- Establishment of qualified wood-based panel plywood and MDF supplier files.
- Regularly supervise and assess the supply of qualified wood-based panel plywood and MDF suppliers.
- According to the regular assessment of wood-based panel, plywood and MDF suppliers, carry out survival of the fittest or coaching.
- Supervision and disposal of problems found.
3、 Development and assessment of wood-based panel, plywood and MDF suppliers
The purchasing personnel usually assess the suppliers of wood-based panels, plywood and MDF from the aspects of price, quality, delivery time and quantity and coordination (service), and calculate the score in the form of a hundred-point system. As for how to score, each company can decide on its own according to the specific situation:
- Price: calculate a relatively standard and reasonable price based on the lowest price, highest price, average price and self-valuation of similar materials in the market.
- Quality:
A. Batch return rate: the quality is judged according to the batch return rate within a fixed period of time (such as one month, one quarter, half a year, and one year). For 50 batches of wood-based panel plywood and MDF delivered by a supplier in the previous half year, 3 batches are returned, and the batch return rate=3 ÷ 50 × 100%=6%, the higher the batch return rate, the poorer the quality and the lower the score.
B. Average pass rate: calculate the average value of pass rate in a fixed time according to the pass rate of each delivery to determine the quality. For example, in January, a wood-based panel plywood and MDF supplier delivered three times, and the pass rate was 90%, 85%, and 95%, respectively, then the average pass rate=(90%+85%+95%) ÷ 3=90%. The higher the pass rate, the better the quality, and the higher the score.
C. Total pass rate: judge the quality according to the total pass rate in a fixed period of time. For example, a wood-based panel plywood and MDF supplier delivered 10000 pieces in five batches in the first quarter, and the total pass rate is 9850, then the pass rate=9850 ÷ 1000 × 100%=98.5%, the higher the pass rate, the better the quality and the higher the score.
- Delivery time and quantity:
Delivery rate=delivery quantity ÷ order quantity × 100%, the higher the delivery rate, the higher the score.
Overdue rate:=number of overdue batches ÷ number of delivery batches × 100%, the higher the overdue rate, the lower the score; The longer the overdue rate, the more points will be deducted; In case of work stoppage and material shortage due to delay, the score will be increased.
- Compatibility (service): In terms of compatibility, appropriate scores should be allocated. The better the service, the more the score.
Add the above three scores to get the total score, which is the final evaluation score to evaluate the performance of wood-based panel plywood and MDF suppliers.
4、 Methods for selecting qualified wood-based panel plywood and MDF suppliers
- Evaluation of production capacity of wood-based panel, plywood and MDF suppliers.
- On-site evaluation of quality assurance system for wood-based panel, plywood and MDF supply commodities.
- Evaluation of product samples.
- Compare the history of similar products.
- Compare the inspection and test results of similar products.
- Compare the use experience of other users.
5、 Ten principles for quality management of wood-based panel, plywood and MDF suppliers
- The purchaser can send full-time resident personnel to important wood-based panel plywood and MDF suppliers, or often conduct quality inspection on wood-based panel plywood and MDF suppliers.
- The purchaser regularly or irregularly carries out quality inspection or on-site inspection on wood-based panels, plywood and MDF supplies.
- The purchaser reduces the excessive dependence on individual plywood and MDF suppliers, and disperses the procurement risk.
