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 }& c% c; x3 Q  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.
* {/ y9 V# B0 \  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.
$ G  w; N* Q# ]4 x  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.
4 @( b$ ^1 e0 C4 U  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 T# t5 D- y' x" C  e. L% S' 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.

不胜感激！

begin P_A arriving
$ H3 k2 E2 H; C: Pmove into Q_wait /*Capacity is infinte*/

send to P_B

  u+ E( }, a7 H3 V1 rin 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.

Remember to turn off the animation before you run your model.
