摘要
根据新型号涡轴发动机质量要求,综合考虑系统设计与用户需求,以指标体系构建方法为指导,构建涡轴发动机型号发展评估指标体系。运用粗糙集理论对世界上典型的同类型涡轴发动机的各种指标进行数据挖掘,利用信息熵方法求出各指标的权重值,克服了传统主观赋权法的随意性与客观构权时可能存在的偏差。最后,建立涡轴发动机型号发展综合评价决策模型并用实例证明了这种方法的可行性。
An index system is proposed,which is based on quality standards of the new turboshaft engine program,integrated 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 entropy is used to compute the weighting coefficient of every index.This approach overcomes the subjectivity of traditional subjective way of weighting coefficient determination and overcomes potential error of impersonal way of weighting coefficient determination.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.
