| Abstract: | Group decision making method of improved level soft set under intuitionistic fuzzy soft matrix environment is studied. Firstly, giving an aggregation method of IFSM which the expert＇ s weight is unknown , and the λmed（E） level soft set is proposed based on the λmed（E） level soft set; meanwhile, three average level soft set is presented based on the λmed（E） level soft set. Then calculate the choice value of every alternatives by use of the level soft set to obtain the optimal decision. Finally, a practical example has been demonstrated the reasonability and feasibility of the methods. |
