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,9 t* W! [, e2 f
  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.1 i$ m2 c7 O  ]$ ?
  Loads are processed by each operator for the following time:
; A5 M: n; a; B: b0 p$ D% e  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 s4 I8 ^8 h) Q& e! 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.. x  u: P& Q' B9 D' w0 v+ y
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ I$ |( x3 x! D7 t! cSend 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.9 W' D2 o$ z2 W0 i5 P2 n) S

- \4 n% O! N" f: C* t* _After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.3 w5 O( Y$ \/ p, Z, }* T* ]/ f

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