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,
- J5 D# f' q& O5 U+ G 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.+ _5 X3 r$ C3 @/ w7 M8 p( R z
Loads are processed by each operator for the following time:( R8 G8 z) b2 E2 P
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 R1 Y6 Z- P, `+ e# n1 ?5 n* 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.
% N' I( l8 O$ j( i' W& G% h4 ] Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' D- n4 `: r$ k$ E1 |9 n3 m
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.) n2 N0 G$ l/ C( y5 V* u
! A: Y) m8 z8 Y j+ V
问题:
5 r7 g1 Y7 O: z3 ]* k% SAfter running the model for 10,000 days, what was the average number of loads in each process?
" e5 u# j& O$ r+ p9 l+ Q; C, W% ~/ Z
0 r: a! _# g1 V+ }) {不胜感激! |
