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,
# A. t: W! A- [ i- B4 v1 y 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.
' c9 @- K- f5 d' y: u" ] Loads are processed by each operator for the following time:: O8 k: r) K0 U7 s2 c2 u2 H+ E, U, h& ~8 c
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! n0 t/ O+ v- G2 W
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.
! h# p! Q d% O8 r/ Y# \2 V Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' B+ K. w: D3 L0 JSend 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.6 q! @) S3 e5 _7 Y

问题:
