For the gray attributes of the equipment program and its difficulty to carry out the quantitative assessment of the equip-ment program information, the gray relation projection method is simply reviewed. Combining the super-data envelopment analysis (DEA) model and the gray system theory, a new super-DEA for measuring the weight is proposed, and a gray relation projection model is established to rank the equipment programs. Final y, this approach is used to evaluate the equipment program. The results are verified valid and can provide a new way for evaluating the equipment program.
