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,
$ a' Y$ p5 O7 \8 b; d: f" V& 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.
: f% b: l' K9 C, q8 H Loads are processed by each operator for the following time:9 a6 C6 e) G; s! h
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- y. }# m1 m8 B6 ?& t5 U- F
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.$ k" S; f: F: Y2 M
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 M7 l: j! \) ?5 M! @
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.
0 b. h2 \2 D8 j; G: H; {6 ^+ |) W- R, z' F& b
问题:/ O0 i5 P, Y3 b# O; l
After running the model for 10,000 days, what was the average number of loads in each process?/ C; g( l1 x, f" U( q4 a3 D
0 B' q/ _1 j: ^ B, j1 _. C不胜感激! |
