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,
T+ F K! Y$ I 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.. S3 a, K3 A8 l, Q) }! {% A4 p, R
Loads are processed by each operator for the following time:
2 @8 B4 ?3 k9 h6 F# @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* I- O( b1 V1 \( @7 ^; L 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.. y7 ~% v' }/ q5 x
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) [) @" \5 C+ ?; n" A( 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.1 x5 e/ t$ D( @; h4 `& l; E

" B/ Y( S% N) _/ R9 WAfter running the model for 10,000 days, what was the average number of loads in each process?* k# Q9 U, Z" s$ t" g' ~. {: q
