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,& a" J+ [4 D& J; p
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 U0 V' D: m' C" Y) J- V# i Loads are processed by each operator for the following time:
7 q: r# M( h5 D" P' G" R* Y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! _& ~! c3 j# l) V9 Y
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.
l2 g& Z/ k) k/ c R& g Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ Z* e( T1 ^( h S3 I+ r* z$ ^8 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.5 I+ ?6 w* ?/ G4 X6 u3 z3 O; A7 d

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