That strategy can be viable; it's discussed in the Wikipedia article: https://en.wikipedia.org/wiki/Multi-objective_optimization#N...

As is suggested there, though, implementing this no-preference strategy requires some clean rescaling of the component functions in order to yield equal significance for all of them. If you have such a rescaling, that's outstanding; however, as I suggested in the section of the article dealing with the impact of the choice of currency, rescaling a problem may be a difficult proposition. This is especially true for problems that aren't as simple as the toy problem I've proposed here.
