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,
$ @5 P! _# ~$ m7 L' ~8 O 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.1 K* N4 c7 A. b1 F6 h) w- n
Loads are processed by each operator for the following time:
9 f/ A' N& ]9 Q# Z& i" _# W- S Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 S0 Y6 p7 _1 U
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.
6 @( M, Z! r7 ^1 Z7 [( t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 x E6 c! F. V# lSend 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.
f0 Y, `- V5 [# O5 r6 X- i; T1 Z G: v
问题:
( i7 z. z& h0 b- T, cAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
