Abstract：An index system is proposed ,which is based on quality standards of the new turboshaft engine program ,in‐tegrated considering the system designation and needs of users .The rough set theory is applied to explore the index data of other turboshaft engines with similar capabilities which are used now in other countries .The conception of information entro‐py is used to compute the weighting coefficient of every index .This approach overcomes the subjectivity of traditional subjec‐tive way of weighting coefficient determination and overcomes potential error of impersonal way of weighting coefficient de‐termination .At last ,the comprehensive evaluation decision model of the turboshaft engine program development is set .The feasibility of the model is verified by a case study .
