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,( y  [) e$ O* _  k& X
  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.
% e( L% H( s9 X* h7 t# S  Loads are processed by each operator for the following time:
! C. W1 a( i* A1 f" G& C/ ]  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& ^& s6 F5 I5 u  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.
& \2 J' k3 Z2 ^4 z7 A$ |  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 p5 f- d3 o' p1 l3 `; g/ {
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.: x) B# t' Z: J# V8 d' I

0 W$ I2 W: @7 [/ @- G2 X9 f1 F7 L问题:/ M; G1 F1 F& Y  A" M* R
After running the model for 10,000 days, what was the average number of loads in each process?7 [" |: l5 h' d( E' ]3 S
/ C9 z3 Y% A# P# ]
不胜感激!

in P_C, you need to send to die.! \# u7 b, J' _

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days./ m5 E' f$ n$ E: w$ a' @

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