The entropy-gray-correlation-Topsis method is used to establish a tender target selection model. The model normalises indicator values and constructs indicator matrices for the number of people, proportion of professional staff, fixed assets, production infrastructure conditions, procurement contracts and return on assets of the enterprise, calculates the Euclidean distance and grey correlation between units and ideal and negative ideal solutions, analyses the primary indicator weight coefficients and secondary weight indices The final quantitative ranking is carried out to obtain the assessed values of the tenderee in terms of corporate strength, competitiveness, financial position and operational risk, and to select the tenderee with the best conditions. This model provides a reasonable and scientific evaluation index system for the selection of tenders.
