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,
- {7 U; j, |1 z" g% T  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.
! J$ i! ~- d2 S, Y  Loads are processed by each operator for the following time:
+ C! J6 o3 X7 ^) q% ?6 R  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.) q: P2 L- g0 @
  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.
5 M0 _. R7 G. U% x$ b# l0 a  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# V" ]/ S. q% S0 q7 i/ eSend 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./ G5 M8 V) O, ~; g
% a! M1 y; @0 X( Q
问题:
0 O0 _! \6 ?; h, Q, \5 WAfter running the model for 10,000 days, what was the average number of loads in each process?1 }, @5 K* ?) P  _" u0 d5 w

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.5 k0 L, o& t+ G8 j: _+ U) V- D

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