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,( n$ D$ T; v# G+ A9 h, a/ _/ D
  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.
3 C7 V8 i% J, R  Loads are processed by each operator for the following time:: J2 O5 m) H* X- Y2 L9 p6 `
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' i$ X& _+ o. o' Q# H$ F
  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.
, g4 K. ]# N! [' |  h  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 J/ d$ M  @! f8 ?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.& q/ m4 r' |6 i! k; C: I0 s
0 H) Q; L( ~2 l# }+ |( u5 j
问题:; V7 ?6 _* n9 N2 `1 B. u+ I" ]
After running the model for 10,000 days, what was the average number of loads in each process?

P_B and P_C is similar

in P_C, you need to send to die.
