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,+ ]& z. S8 k3 K$ w% a
  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.
  X$ X5 U# i/ s6 C  ]  Loads are processed by each operator for the following time:2 Q% |; o( \5 S0 h0 U
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  K5 z0 m3 k! X1 N' ?0 Y  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.
8 U4 f& X2 r$ ^  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
  A- U8 w* Z( }# M# bSend 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.& f3 Q) S2 h0 u9 |9 i

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
