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,
$ S* |, C$ a# o+ f, o. 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.! r8 d0 m/ z0 Y. M
Loads are processed by each operator for the following time:9 |5 d5 b5 T" I
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 r6 k! D, Z! Q- }3 P
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.
& N! u- i) ~9 g: M9 e Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! C) y3 c, O8 s! ^. ?# ^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.$ T$ o9 E7 ?6 x" T5 ]/ ]
3 M' N5 t- X% J/ C. M* h; n$ j% I问题:" k4 {, `$ g3 B. z; _1 U5 V: Q& y
After running the model for 10,000 days, what was the average number of loads in each process?6 H, I+ I3 V/ d" H
$ k- s$ S3 _6 ?- s" B! Q/ a
不胜感激! |
