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,' I7 l9 Y( k8 ~) R- B5 s
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. p3 X$ H& \: m9 G# _
Loads are processed by each operator for the following time:
2 }+ S5 E Q$ X3 a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. q% P4 A+ g. f# I: T 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.
8 u; `9 M* o/ ~9 A _/ C Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# D \) F, l& \# i w7 d9 h, pSend 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.- ?$ E4 R! w5 |. O

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