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,
; k$ y. M+ E) R7 n# t. N( c 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.
~& } w+ Z( D) O" \5 o: T. I Loads are processed by each operator for the following time:
`; U' c( b7 R7 j P Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 t( ^! _3 R0 v" r/ o 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.
7 _) D8 @ p4 B' U Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- ?, d, V9 c* g' m5 T1 p
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.4 _0 O7 i! M/ m: L9 u4 |" u
( M; ~5 l" H3 ~* u问题:
% O' Z$ E% v8 gAfter running the model for 10,000 days, what was the average number of loads in each process?/ ` p, F# c8 g6 L$ }
+ b5 N& H( A8 b, K2 w2 K1 h不胜感激! |
