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,
5 g8 O2 k: m* s Z4 z 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.1 ~# `# H/ P$ p8 }& q
Loads are processed by each operator for the following time:# v% J! }7 G" y+ X) q6 f/ _+ N8 o6 ^: N
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 I8 I. G% c _* e' g 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.. o; S! ?8 ^ m9 ^
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 P/ P9 I# S) g3 |( HSend 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.
- J' w( X9 U( ^; i$ k

After running the model for 10,000 days, what was the average number of loads in each process?0 b% ]" G( T5 k7 i+ s
