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,
( ~( ^+ ? p; f8 \ D 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.
j1 q0 f' {9 V& R" U( l Loads are processed by each operator for the following time:$ N3 p2 k2 d+ V1 S' `* x6 T- E5 C
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
1 }) |% H! g) K0 w0 J- k1 H. e4 g 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.
" K& `1 l) {! S Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; \6 g% A, [" m+ |# D$ T Z/ c
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.
7 q& [9 [8 L ~2 N L" W; s( | ^( N6 e0 ~8 o
问题:
4 m, O. W) G4 R$ l* c5 r, fAfter running the model for 10,000 days, what was the average number of loads in each process?
0 B. S' I |( p' y1 d
