英文摘要： The incomplete electronic medical records contain a great deal of potential applying values，which attribute reduction issue appears widely in the clinical feature selection and decision support system.Therefore,it has become a kernel technology in many applying fields.There is a huge challenge for attribute reduction because a great lot of incomplete values exist.So it is essential to solve the problems about the attribute reduction of imcomplete electrionic medical records by adopting some effective theories and methods.That attribute reduction is being researched from the perspectives of the co-evolutionary theory is new development status in its domain.At present,it is still emerging throughout the world, and there are many unknown fields needed to be explored. Based on the attribute features of incomplete electronic medical records,we will carry on the research on the theory,algorithm and key technology of attribute co-evolutionary reduction,explore the quantum co-evolutionary mechanism based on the evolutionary game theory, and refine an uniform evolutionary framework of the Nash equilibrium for agents' co-evolutionary game reduction under the bounded retionality. Meanwhile we will propose a new complete set of attribute co-evolutionary reduction algorithm and model,which will make up for the lacking of tr
