刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,
7 o5 [5 t# E8 d Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.
# E7 e" G6 ]- ? Loads are processed by each operator for the following time:
. i7 P: I0 z9 B, E- e3 |# c D P7 | Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 \9 ?! m d( x' Y; R% {. X Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
1 K! q# u) a0 ] Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% x* X0 ]3 W' m5 s. w8 ^* E1 J
Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers./ S5 e7 E% D8 w2 A ~$ o" R
