In order to scientifically and rationally select the supplier of the teaching specialized hydraulic test platform, the influencing factors of selecting suppliers for teaching specialized hydraulic test platform were determined based on the method of selecting suppliers for construction machinery enterprises, and the evaluation model for the teaching specialized hydraulic test platform was established by using the technique for order preference by similarity to an ideal solution(TOPSIS).The entropy weight method was used to determine the weight of the evaluation index so as to eliminate the defect that the subjective factors were too much. Taking a teaching specialized hydraulic test platform purchased by a university as an example, a set of practical and operable evaluation system for the teaching specialized hydraulic test platform was established through analysis and calculation. The system provides some basis for the procurement and management of university experimental instruments to purchase hydraulic test platform.
