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,
) l& l5 U4 j% \+ n) R0 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.
) K2 `4 W9 @( `9 u& r( u Loads are processed by each operator for the following time:
+ M$ H/ H# G& e ?9 P$ o, n Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 j* S, d8 C5 s# D 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 x% [$ s e: n9 V. H Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* _' {3 F2 I, L
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.
" y& _" o1 ^0 V$ a7 j$ t) x$ U4 ~$ U6 \1 p' W
问题:
- \' L. N/ R" B' U- g8 M, j" b/ bAfter running the model for 10,000 days, what was the average number of loads in each process?
