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,1 _( T+ @$ O7 F( Q! P* j! t9 a
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.
. g( y8 I0 m3 B0 M+ c) _ Loads are processed by each operator for the following time:5 U7 A! d! ? m3 z- O$ ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 P" m! {/ y0 F8 S
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.
( f# m3 C! }. E0 g Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: F9 ~0 b: U" bSend 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.9 j% O5 W& k5 o! T

After running the model for 10,000 days, what was the average number of loads in each process?
