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,
# [7 v8 B+ U" R l9 `# |8 _3 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.2 a" N7 }9 y+ O2 N3 V4 o) U9 _; e
Loads are processed by each operator for the following time:
$ z* W a Y" H# X8 b9 Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
" I& t! F; ^ K( q- @ 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.
( b9 y% I, A( Z5 l0 V) |3 I5 U Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ m9 h4 I, F" O6 a1 N( Z% uSend 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 k/ X" s7 A0 W) i# Z* ]/ Z
: a9 c) V) @! n% |. ~问题:8 F9 p3 Z. S- M, G% S8 J
After running the model for 10,000 days, what was the average number of loads in each process?
