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,% J9 L, n) M# H* i* h2 I
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.+ l2 B0 ]' f) i2 h3 T- _' ` @- u6 S1 S
Loads are processed by each operator for the following time:
' T2 ~: _, l! c, Z M. U Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 F) A! u' j/ j/ `9 A) h- P0 u- R
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.3 J+ N2 j- O4 t, S
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.1 X8 Y7 D% b/ @; i) y3 Q# }( h
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.% B% a) R H" N
) K( m8 d, G& D) u6 d$ y% @6 f) ^ F W
问题:( v' J5 {, f; y+ i: A
After running the model for 10,000 days, what was the average number of loads in each process?( L; I; }9 f% }) D" t

不胜感激! |
