Through different stages of the engineering life-cycle of the characteristics of the social impact of inductive summary

build the engineering life-cycle phase of social impact evaluation index system

using the analytic hierarchy process(AHP) to determine weights of project in different stages of the engineering life-cycle of social impact

the results show that the decision phase and scrap stage are important stages of social influence on.Determination of the weighing values of each stage will provide reference for the project decision makers and managers.
