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,2 \  |9 {6 `, n9 f9 O
  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.
/ N. y8 Z+ w( k( }  Loads are processed by each operator for the following time:* z! `- y# y+ I) C+ t% L1 }
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. f5 Q' i+ K/ b  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.
* i. J) }% E$ E# ^* G' S  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 X9 \5 @- ]4 X4 H1 k% a
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.
% O0 x/ U4 x7 Q, D% U" ]; I3 ^

After running the model for 10,000 days, what was the average number of loads in each process?7 d+ ^( Y. w2 m1 \

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.
