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,1 a; j9 l& n* M: {5 R# I
  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.
+ e. J; {5 s8 s( ^' d5 Z( s; z3 ?  Loads are processed by each operator for the following time:
; W. E0 g4 {' \0 G: ?  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.9 W% }/ R7 S- 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.3 n, L4 u0 X" y1 C- n& W2 g5 g6 P
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: g, ]! B3 A! v2 [: w
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.5 D3 x. i/ t- ?6 r8 F# W8 f

' e. H5 Z+ _9 f1 |& b问题:, |; w2 _3 B& ]8 c7 r
After running the model for 10,000 days, what was the average number of loads in each process?
