[0020] The price, quality and delivery time of the goods are used as scoring indicators of the weighted scoring model;

[0021] The purchaser can customize the weights assigned to each scoring indicator as needed. For example, if the purchaser has high requirements for the quality of the goods, the weight of quality can be increased and other weights can be relatively reduced; if the purchaser pays more attention to the quality and delivery time of the goods, the weights of quality and delivery time can be increased and the weight of price can be reduced;

[0022] Score the price, quality, and delivery time of the goods based on the custom rules to obtain a price score, a quality score, and a delivery time score, wherein the delivery time is calculated based on the production speed and the quantity or weight in the procurement information;

[0023] Multiply the price score, quality score, and delivery time score by their corresponding weights and add them together to get the final score;

[0024] The suppliers corresponding to the goods information whose final scores are greater than the set score threshold are matched with the purchaser.

[0025] Furthermore, the price score calculation includes the following steps:

[0026] Get the prices of goods with the same name and model from various suppliers;

[0027] Filter abnormal goods prices based on the box plot method to obtain normal goods prices;

[0028] From the normal commodity prices, select the lowest commodity price of each commodity with the same name and model;

[0029] Calculate the ratio of the price of each supplier's goods of the same name and model that is higher than the corresponding lowest price of goods to obtain the premium ratio, which is (goods price - lowest price of goods) / lowest price of goods;

[0030] The price score is calculated based on the premium ratio, price score = 100*(1-premium ratio), where the premium ratio does not exceed 1.

[0031] Furthermore, the quality information module is also used to calculate the actual delivery time after the purchaser receives the goods based on the time of receipt of the goods and the time of order confirmation, and to combine the actual delivery time and the corresponding quantity of goods into delivery time limit information.

[0032] Further, the quality information module delivers the time limit information to correct the production speed, including the following steps;

[0033] Obtaining historical delivery time limit information, wherein the historical delivery time limit information includes historical actual delivery time and corresponding historical goods quantity;

[0034] Based on the historical actual delivery time and the corresponding historical quantity of goods, the historical production speed is obtained;
