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,
9 r+ A% i" F$ @+ j 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.
! r+ ?. o+ X( u Loads are processed by each operator for the following time:
2 ^0 ]# y7 ], V Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.7 h- [/ Z' \/ t9 _- L
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.5 Q! @/ C$ P# b( O. d1 L
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( s! P" x3 L6 `# W/ e
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.9 p6 Q+ b- R. P( \7 L1 K7 U
# X2 \/ H$ D' d" x
问题: h& t, O+ K9 w6 E" z" D5 @( \
After running the model for 10,000 days, what was the average number of loads in each process?
2 ~0 g# D: R% h9 h8 X$ d1 w
2 X8 q, S' _$ a; M) N+ L. f3 B不胜感激! |
