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，
0 [' A+ e" \" B2 M! i6 r  d$ i  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.
  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
) G) `0 S. j+ Y7 v8 L  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" P/ c& H# ~) b  i( }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.

send to P_B

in P_C, you need to send to die.

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