“…In the second experiment, nine different sizes of the jobs n = (10,15,20,25,30,35,40,45,50) are used to test the proposed method, while five different sizes of the jobs n = (10, 20, 30, 40, 50) are used to do so in the third experiment. For each size of the jobs, the normal processing time for M 1 and M 2 is generated from the discrete uniform distributions [1,10], and the normal setup time for M 1 and M 2 is generated from the discrete uniform distributions [1,4]. For all the tests, t 0 = 0 is set, and the deterioration index are set to be three different values, that is, b = 0.1, 2, and 5 for small, medium, and large, respectively.…”
