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,
* Y/ z: [, I" h& `0 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.
' U$ F( O1 x8 z% V$ y. h/ ? Loads are processed by each operator for the following time:
. C" N# A% V. D+ a" t5 H Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 X+ X( o& X4 c# L2 _
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.% I" b) a7 e( T; L. {! C- A
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 E- g5 Q. u0 N6 z+ Y4 ~
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.' d" ^6 f3 x, c h7 w; r
, e* }" m9 D! I! M
问题:& |! o0 y; B* H8 n7 O
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
