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,
8 X) a( w) v- s* t  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.
2 k& T- {' k6 y  Loads are processed by each operator for the following time:+ V6 x% u3 p' ?1 ~" o; G+ g% [
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." o4 b4 g" s: @, u$ W5 c8 l
  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.9 u  b2 X0 q6 F9 B( l: x
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# D4 \7 f$ N, M: c! O. SSend 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.  o* ?7 q) E8 V" ~
