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,) P8 V6 a$ _9 ^% L, s
  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.
9 f& K; M% p$ E) R* H! X) n  Loads are processed by each operator for the following time:7 |/ s- w9 o7 m
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 X- Z, [7 a# \1 ~5 v" |3 {/ @  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." d! V; g4 g4 B* `
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.$ s$ h3 j$ o' v, H2 G4 q8 Q! g5 X
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.

问题:
, W' j4 F7 C& x" dAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!
