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,
9 v% T+ H' `- M, }" [6 ?2 S 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.& Q6 d4 A4 |5 }. l
Loads are processed by each operator for the following time:- x; C' U: t4 \0 s8 {4 \# x& P
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.8 z. a' d' x% K" O: 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.2 m# t5 _1 D+ f3 v6 Q
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# S7 |. y% Z: T4 ~) R. wSend 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.- n/ [( D: d4 W( ^4 H6 j3 A9 l
1 G: Z/ X3 _7 k; d8 E问题:
9 ?1 q4 t$ [+ O3 t* ]" v& S7 pAfter running the model for 10,000 days, what was the average number of loads in each process?
