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,$ L! X" _# x9 d: K; j
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.
2 P/ S* g4 P1 Y2 h1 A8 S+ f4 ~ Loads are processed by each operator for the following time:) M& V6 ?; q" B2 c$ q( n, A
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 i2 ~) L* f1 ^( Q! y ]. g
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.
6 q/ F0 }: n7 j* V2 n5 t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# h3 f ~1 @9 P2 S) Z
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.

After running the model for 10,000 days, what was the average number of loads in each process?; E! L& Y5 E. A3 e7 X* ]# G
