Normal distribution or Uniform distribution

    Hello,
    I have two jobs,Normal distribution with mean of 4.5 minutes and standard deviation of 1.5 minutes for type 1 and uniformly distributed between 1 and 3 minutes for type 2

    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!
