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，
- J& f$ p4 E4 {5 T- S, H  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:
  P$ W7 {) [* x; W; l% M( Q  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.
% t+ v0 b) v. @" k" Y/ l$ r  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) Y% r9 Z0 b% u$ i+ ^5 USend 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.

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