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 i5 O1 _8 O# Q0 [! H. G5 N 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.
7 g) B0 Z3 w% F6 e$ }+ w% O- w Loads are processed by each operator for the following time:
% E8 P; {5 V, M- _* j- G- y" \3 O3 h Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& s5 a7 w9 L( I" ?
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.! M- r* K: S' Z7 d) N7 w# p
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.+ s4 |9 n/ g0 r1 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 G3 Y, O- T% [/ O: g u

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