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 k$ _) G( @3 a8 J$ V1 @
  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 E* a9 ~, n0 M  Loads are processed by each operator for the following time:8 k  [' @: V7 `) ]( t% n# j
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& f% d) e, |! g  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.
/ h, y" P; H% V# v$ W  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 S) j5 _; D" E9 }& B; E( ?0 `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.' F/ c5 ~; t* h$ \2 r4 f* l
2 C6 p/ o% A9 h- n9 J
问题:8 _# }; W$ w+ e4 z# M# ?. @
After running the model for 10,000 days, what was the average number of loads in each process?
