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,+ w3 T* D* e( e! S8 l
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.3 V2 S, n1 }0 \. j$ z
Loads are processed by each operator for the following time:" q2 T) d! \9 K6 O/ U8 T
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ `! e; d0 \/ _$ e3 Z 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.
' J e: T# x. E3 l9 l6 f/ V Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 p5 U( h7 o, V4 x0 ]. l( x% T
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.1 {; L1 w3 x: {1 g) {: R' ~; z

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