Study on the integrated decision model of Grey Hierarchy

By analyzing Grey decision, we think it will come down to benefits and effects of all parts during the decision. So, only if these benefits and effects are fully considered, the result of decision is scientific and rational. For multi-hierarchy decisions, the decision-makers must be endowed to different weight because of the different actions of them. In this paper, the authors deal with the A middot B-hierarchy decision. First we define the A middot B-hierarchy decision order sequences and A middot B-hierarchy decision order matrix, then compute the weighed grey incidence degree between neighbouring hierarchies of decision sequences. Furthermore, we made the integrated decision model of grey weighed hierarchy owning to the maximum principle, and develop the schemes to find the satisfied grey classes and satisfied items. Last, we illustrate the model.
