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 ~' \9 D% A$ v1 E 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" `& y) K8 E2 M8 o
Loads are processed by each operator for the following time:: M i3 I2 c1 `+ @
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! W- o9 E0 x$ N 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.
! C8 n4 d" w e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* a; t. t% S- HSend 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.
M; Q+ O7 C( h( f- d& h8 X2 s, E) R
8 F( e8 E* I3 j3 P2 D p7 B* y问题:% C4 L& ~/ h- Q% q ^: `' \* C! f
After running the model for 10,000 days, what was the average number of loads in each process?& G* h1 k+ O# F. K
# _9 X( U1 M6 x0 P! c3 | S0 z0 m8 V
不胜感激! |
