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,
7 C& m8 Z! ~' s, V# x0 G 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.: j" c" E5 N5 k4 w; G( ^) _
Loads are processed by each operator for the following time:" {$ }, u$ K' N e0 G, `4 i
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* N7 {2 q5 X2 w" m" n
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.
2 w) ?- u0 l: N Worker_C does the job in a uniformly distributed time between 30 and 90 mins. \/ z# a8 V7 D) k8 |2 y
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 R9 m4 R, M! k2 E- F" k: e9 R

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