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,3 D. t8 |& y. c% c
  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.
& H4 [; w% \( I; v4 U  Loads are processed by each operator for the following time:
, u$ L& V" d7 ~) t  `- S  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ ?+ c3 |  N+ \9 ^7 w5 a9 H  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.
+ k7 T  l- J+ x% k# S  t7 \  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
' ~. z; D+ t2 Y: ?: kSend 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.
