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,0 Q- C$ ^4 t4 ]
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.0 [8 J1 Q7 Y: ]( C& f6 k- L9 M0 E* \
Loads are processed by each operator for the following time:
. `: I8 ~. V, J+ { p" e9 @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& p" j; r4 b) n$ n' j 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.
7 H) k0 }5 V7 Q0 N- l! K Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& I4 f% j$ K$ v2 g( ZSend 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.
( Q2 q5 }- _) ~$ \" l0 \" {: I& T( r

After running the model for 10,000 days, what was the average number of loads in each process?: _' h8 o9 o' G+ P
