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,
1 A G3 G/ _, V b& Y7 x7 U( C, ^ 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+ O! K2 Z9 x5 b2 w Loads are processed by each operator for the following time:
* ^: F7 b9 L4 S' O% R- E. [/ X Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* j: W: {/ r: ?
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 Q9 |2 b2 b: R ?
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) @0 x- z* f0 h# N3 z, mSend 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.
6 w8 S! Q' e& ?8 ?
* o& _/ u1 r+ V% J8 T. F问题:$ P9 t1 e$ I3 V' U
After running the model for 10,000 days, what was the average number of loads in each process?* V8 X# ~# x* U5 I
! j' K i6 n$ ~不胜感激! |
