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,
$ M! Z: m$ O, R, }5 M Y u( h 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.
) T% t. f' r! }# V7 j3 W& m; u Loads are processed by each operator for the following time:
7 \8 s- k4 |& B' y/ v+ v Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 ^, i4 @& }, U) B2 Z$ e7 a' t
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.1 Z+ `- {' N& ~4 s3 E- B+ Y; z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- r7 S/ i; k8 I [3 j
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." D5 k% a0 v' G2 k3 |* |
$ F' T) Y6 ?7 y& c

After running the model for 10,000 days, what was the average number of loads in each process?, T9 D7 k& w$ Y* |$ L

不胜感激! |
