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,! j6 \# Y% D% B3 x
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.
5 ~+ K) E D9 u Loads are processed by each operator for the following time:+ F* f8 |+ r, N4 f" D
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ ?5 A t& K' _1 A4 |! \/ { 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.
( V; x0 n( O& h4 b) g$ D8 C Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- C1 d& t, x4 I
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.' _ P6 O5 d# j3 j- n \

After running the model for 10,000 days, what was the average number of loads in each process?7 r4 f- Z2 n; W r0 s; W: w' s
