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,
3 S! y' y4 Z) N! q% h4 b 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.4 |. `1 k# F0 h, U, }3 ~/ N
Loads are processed by each operator for the following time:
+ t, k; S0 B- K" @, U* K# u Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! @2 N3 T% u6 Q2 }/ ?' M6 c 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.& [2 c5 h! e0 S5 l1 B+ S
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& d0 s5 p2 z( w% [: 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.: M6 z: V2 e* g/ T9 V+ C8 D
- ]" p7 s5 R/ f9 _1 M+ i& N
问题:# B- J2 y& o& R! z' ?
After running the model for 10,000 days, what was the average number of loads in each process?/ A u( m0 X/ t
6 y1 V1 s6 O, Z
不胜感激! |
