There are now four vectors, one for each of the four merits. The effectiveness and the simplicity of the proposed maximum eigenvalue threshold consistency test method and the inconsistency identification and adjustment method are shown by two illustrative examples of emergent situations. Of special interest is to see if these changes change the order of the alternatives. To reduce the times of consistency test, a block diagonal matrix is introduced for the RPCM to conduct consistency tests simultaneously for all comparison matrices.

AHP structures a decision problem into a hierarchy with a goal, decision criteria, and alternatives, while the ANP structures it as a network. The sense being influenced or influencing must apply to all the criteria for the four control hierarchies for the entire decision. The ANP would allow consideration of the interdependence of price, safety, and comfort. For benefits and opportunities, ask what gives the most benefits or presents the greatest neywork to influence fulfillment of that control criterion.
The AHP would assume that purchase price, safety, and comfort are independent of one another, and would evaluate each of the sedans independently on those criteria.
The alternative with the largest ratio is chosen for some decisions. There are now four vectors, one for each of the four merits.

For costs and risks, ask what incurs the most cost or faces the greatest risk. Determine the control criteria and subcriteria in the four control hierarchies one each for the benefits, opportunities, costs and risks of that decision and obtain their priorities from paired comparison matrices.
To illustrate this, consider a simple decision about buying an analytix.
Enter in the appropriate position the priorities derived from the paired comparisons as subcolumns proocess the prodess column of the supermatrix. Perform paired comparisons on the clusters as they influence each cluster to which they are connected with respect to the given control criterion. The proposed model is implemented in a company of electronic. In the AHP, each element in the hierarchy is considered to be independent of all the others—the decision criteria are considered to be independent of one another, and the alternatives are considered to be independent of the decision criteria and of each other.

Studying these applications can be very useful in understanding the complexities of the ANP. There are numerous practical applications of ANP, many of them involving complex decisions about benefits Bopportunities Ocosts C and risks R.
How significant the change is can be measured with the Compatibility Index of the original outcome and each new outcome. To reduce the times of consistency test, a block diagonal matrix is introduced for the RPCM to conduct consistency tests simultaneously for all comparison matrices.
For each alternative, subtract the sum of the weighted costs and risks from the sum of the weighted benefits and opportunities. Normalize the four ratings thus obtained and use them to calculate the overall synthesis of the four vectors.
He might choose to base his decision on only three factors: Perform paired comparisons on the elements within the clusters themselves according to their influence on each element in another cluster they are connected to outer dependence or on elements in their own cluster inner dependence.
For each control criterion, construct the supermatrix by laying out the clusters in the order they are numbered and all the elements in each cluster both vertically on the left and horizontally at the top.
In this paper, a maximum eigenvalue threshold is proposed as the consistency index for the ANP in risk assessment and decision analysis. The synthesized ideals for all the control criteria under each merit may result in an ideal whose priority is less than one for that merit. If one could get more safety or comfort by paying more for the automobile or less by paying lessthe ANP could take that into account.
