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,
7 C2 }) b# k, Z) s% z# ^, I! ?: W 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.( `7 [% J' F2 o& R- P3 s2 D
Loads are processed by each operator for the following time:
C+ l8 t2 m3 t Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& I4 |! V7 O4 r0 u4 i 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.4 K- f, _* `& u: b
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ n/ W0 o& Z9 Q: T T9 d2 @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.
$ c1 g& _' |' Q1 |. G3 N$ Y) ~; r! @# L+ A: C& @6 o. b3 _. Z9 g
问题:) n; ~8 x3 c' r3 b$ S
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
