Purchasing personnel usually evaluate suppliers in terms of price, quality, delivery, cooperation (service), etc., and take the form of a hundred percent system.

Calculate the score, as to how to distribute the score, each company can decide on its own according to the specific situation:

1. price: according to the lowest price, highest price, average price and self-evaluation of similar materials in the market, calculate a more standard and reasonable one?

Price.

2. Quality:

Rejection rate: quality is judged according to the rejection rate within a certain fixed period (such as one month, one quarter, six months and one year). For example, if a supplier delivers 50 batches in the first half of the year and rejects 3 batches, the rejection rate is 3 ÷ 50× 100% = 6%. The higher the rejection rate, the lower the quality and the lower the score.

Average passing rate: according to the passing rate of each delivery, calculate the average passing rate in a fixed time to judge the quality. For example, on June 5438+ 10, a supplier delivered three times, and the qualified rates were 90%, 85% and 95% respectively, so the average qualified rate =(90%+85%+95%)-3 = 90%, and the higher the qualified rate.

Total qualified rate: judge the quality according to the total qualified rate in a fixed time. For example, a supplier delivered 10000 pieces in five batches in the first quarter, and the total qualified number was 9850 pieces, so the qualified rate = 9850 ÷1000×100% = 98.5%.

3. Delivery time and quantity:

Delivery rate = delivered quantity ÷ ordered quantity × 100%. The higher the delivery rate, the more points.

Overdue rate: = number of overdue batches ÷ number of delivery batches ×100%; The higher the overdue rate, the less the score; The longer the overdue rate, the more points will be deducted; Overdue shutdown, aggravated punishment.

4. Cooperation (service): In terms of cooperation, appropriate scores should be provided. The better the service, the more points you get.

Add the above three scores to get the total score, which is the final evaluation score, so as to evaluate the performance of suppliers.
