I am working on simio and i have to decide job priority according to their processing time. smaller the processing time, higher the priority. I don't know how to compare between normal and uniform distribution.

First of all: the question "... has smaller processing time..." is meaningless; both processing times are random, so sometimes the uniform will be less than the normal, while other times it will be the opposite. You need to decide what "smaller" means; is it smaller in expectation or do you look at quantities like $P(A < B)$, or what? YOU decide!
