Intuitive judgment is a method to analyze, evaluate and compare suppliers according to the information obtained from consultation and investigation. Mainly according to the purchasing personnel's understanding of the supplier's product quality, product price, after-sales service and other nine evaluation indicators, or several important evaluation indicators considered by the enterprise, a preliminary review is carried out, and then several suppliers who are considered to be better are put forward. Organize a review meeting attended by relevant leaders to conduct a comprehensive review, and determine the best supplier through the comprehensive results of the review. This method has many subjective factors, and it is a qualitative method to select suppliers. Generally, it is used to determine the old suppliers who know suppliers well, have a long cooperation time and have a good reputation in the past, or to select suppliers of accessories with less consumption.

2. Bidding method

For materials with high consumption and fierce competition, it is difficult to judge the quality of that supplier by intuitive methods in a short time. At this time, it can be determined by bidding. This is a kind of enterprise that puts forward the bidding conditions, the supplier bids, and then the enterprise wins the bid, and establishes a cooperative partnership with the supplier who puts forward the most favorable conditions. Bidding can select excellent suppliers in a wider range.

3 negotiation and selection methods

For materials with many suppliers and relatively balanced supply and demand, suppliers can be selected through negotiation. Enterprises choose several suppliers from suppliers, and then negotiate with them on product quality, product quantity, product price, on-time delivery rate, after-sales service and technical service. And reach a long-term cooperation agreement on the basis of mutual benefit.

4 procurement cost analysis method

By calculating the purchase cost, we can analyze and compare the suppliers who can meet the quality and delivery requirements. Procurement cost includes the sum of product price, transportation cost, transaction cost and other expenses.

Compared with the above three methods, the procurement cost analysis method has a higher degree of quantification, but it also has certain limitations, so it is impossible to make quantitative analysis from the overall evaluation, so as to choose excellent suppliers as partners. If it is to be fully quantified, the credibility may be higher.
