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 C- i1 k' H+ J/ d8 h2 Z' W2 `1 A5 Z
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.
+ t& s0 j$ _' c8 o6 t. T5 k Loads are processed by each operator for the following time:
1 ^9 g$ P- X* Y4 J Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 }' y3 U. {( y9 D; B, y! F& x
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.' E' U" e, q- z- O* C
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
4 H) A4 W% L& q( C9 ?2 C8 C- BSend 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.1 Z0 P. O; W% ~
5 E) Z6 m' o6 X- ~3 E! b问题:
8 P \" s- p, A+ r4 TAfter running the model for 10,000 days, what was the average number of loads in each process?
