Weighted Sum Method And Weighted Product Method
Published 2012 · Mathematics
In this chapter we look at two simple multi-criteria decision-making methods, the Weighted Sum method and the Weighted Product method. In the Weighted Sum method the score of an alternative is equal to the weighted sum of its evaluation ratings, where the weights are the importance weights associated with each attribute. In the Weighted Product method, instead of calculating sub-scores by multiplying performance scores times attribute importance, performance scores are raised to the power of the attribute importance weight.
