Abstract: With the extensive application of AHP in group decision making，some defects of it emerged.For example，when AHP is applied，incomplete matrix，different weights between experts and reliability of matrix are not enough taken into account.Owing to the defects of existing method，after possibility-satisfiability degree in multi-objective decision is introduced to compatibility check of AHP，the authors put forward an improved AHP based on possibility-satisfiability degree.Based on analysis of evaluation factors in supply chain nodal enterprise selection，the two layers of evaluating indexes are proposed.The model of supply chain enterprise selection by using improved AHP is set up.Finally，a case of this model’s application is presented in order to prove efficient of the improved AHP and feasible of the model.
