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,9 n& [4 J% U) n0 n) 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.; b8 z8 u6 A6 a; p2 M( d
Loads are processed by each operator for the following time:
9 m; W& g+ u. _ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 A: Y7 _# O5 Q$ y) c7 O2 }7 W
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.. M. `( T+ V2 H/ a7 X0 d6 [6 k
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 y4 Y/ \8 \6 ?0 \ M g- kSend 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.

问题:
$ ~4 x2 n& w& w( q, G( w. g8 b9 Y6 dAfter running the model for 10,000 days, what was the average number of loads in each process?
