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,
8 f9 Q t" c& o+ Z* O. L' D 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.
( V2 z0 U2 o8 x. d" E+ E& ~1 A Loads are processed by each operator for the following time:
- Z- ~+ x$ y7 O7 {+ Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ U2 S: [4 O o- r$ g8 b
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.
7 ~- b, r+ [0 J" y, d5 M Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) O' `0 \; l- u# jSend 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.! O6 L/ [, p& n6 S5 T; o- P5 _: [
9 D& a; X6 G1 {0 K6 J) n问题:' J/ G4 D! Z, `; P5 b
After running the model for 10,000 days, what was the average number of loads in each process?) m' M- @# I b! @5 I
$ u; s; G0 `0 z, K |) y& b不胜感激! |
