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,
* z8 @5 b5 z! ~" @5 j2 W# b 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.8 Q) d! W- @( h, a, t. d
Loads are processed by each operator for the following time:! ^0 S3 i ~3 v% x$ c% e; w, N
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ ^" q9 s; y0 T3 f; j: f, ?; e 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. \! p \( A2 o1 ?- P* Q8 j! n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.# ~% d( } R7 T L# ?0 B. Y1 e' ~
Send 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 x E2 ~6 Q7 i7 Q$ M

After running the model for 10,000 days, what was the average number of loads in each process?5 X. E& Z: a3 a% k: H/ u+ T# w8 S1 K
