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,
# q: r$ R& d ]8 G$ t% V 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.
) w+ [) r, v. k" h) T! @ Loads are processed by each operator for the following time:
7 _. j, a. L- e9 H Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( ]4 }% J" v* 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.
, u/ h$ E" w& Q# Z ^9 I Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* ?9 N7 W q1 \$ TSend 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./ k# ~0 Q: G9 E
2 f, f( G& M. q/ ^! Z
问题:
, z: v m8 c8 c" ]3 ~9 U7 c' q6 [After running the model for 10,000 days, what was the average number of loads in each process?& F, k" a6 T3 o! C+ y8 e
D$ [7 @2 K1 Z2 P% o* }
不胜感激! |
