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,
% R5 A0 M3 X& u+ L 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.! G/ R: o" R$ Y+ C+ {+ A
Loads are processed by each operator for the following time:+ E! s2 c9 c& D, e: R
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 j$ ^+ S. W& J
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.; i; l* D6 s" X% X( Z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ [. U' e2 C5 t. p, L2 J- c& YSend 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./ H N- v- o8 B# ^, k* W4 r) |
* t) s& U; s- @1 k+ Z' _
问题:
8 k6 I8 q' L5 I1 i( o! cAfter running the model for 10,000 days, what was the average number of loads in each process? A9 w, d+ m L& o H
, z2 i/ q9 Y, I/ L; s# x不胜感激! |
