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,
! m; ]& r+ k, h- K 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.
" v$ S) {. \9 r4 ^- y$ v7 d Loads are processed by each operator for the following time:
# x# c" Y+ ^/ g) @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! p! O% ?( v2 }+ } 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% ?+ l: p4 m9 a& f Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 F" F% ^ P% t, X" j
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. x& n7 Y' J7 ~3 }$ R

After running the model for 10,000 days, what was the average number of loads in each process?
