Information needed to use multi-attribute model?

In order to use a multi-attribute model, you need to have a clear understanding of the objectives of the model. You will also need a list of key decision factors, which can be broken into attributes and weights. You will need to determine the relative importance of each attribute and assign them a weight, relative to the other attributes. You may also need to consider specific criteria and limitations such as budget or resources. Finally, you will need to assign a score to each attribute so that the model can properly evaluate it.
