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 h& e; j9 u! c+ 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.6 k* w1 D% o# S& n
  Loads are processed by each operator for the following time:
) T8 S0 K- U, L) {. F- }  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ U" M' B! {4 u" J7 p7 R- S& ?$ Q  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./ T  I/ R* Y8 M) l5 {
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& q* v; Y! L- {. \. M, LSend 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.
, m3 [5 t  j; w5 r. V" h) R! P0 h) l4 K2 k; h
问题:' e7 g$ B% J9 k# Z! E2 ~; u+ d
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.7 A8 X& K6 A( u# ^( k" K

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