Most production scheduling studies involve comparing the performances of different scheduling methods. Since each scheduling method focuses on a special way to optimise scheduling decisions and is restricted to certain assumptions, fair comparisons of these methods are not straightforward. In this paper, we aim at comparing major scheduling methods in the literature using an experimental environment which provides flexibility such that all methods can interact easily with the environment to obtain required information and execute scheduling decisions. The comparisons help us gain more insights about the advantages and disadvantages of each method in terms of efficiency and effectiveness.
