Finally the dissertation gives a method of evaluating expert's knowledge matrix.The process of making judgment matrix is a continuous deciding one. If a judgment matrix is objective just and reasonable, the follows must be satisfied.Capacity of expert that is knowledge and experiences of certain aspect.Sufficient information , that is experts must be familiar with all schemesSerious attitude that is experts must be just.As to reliability of capacity, the dissertation evaluates it through knowledge matrix. As to reliability of information, the dissertation makes conclusion through amplifying result of before with judgment matrix. As to attitude of expert, analysis of variance is used to obtain result.After those checks, if the judgment matrix is satisfied, the steady vector of weigh can be find through GA.
