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,
1 d. y# p; _+ |6 Q. O9 H M 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.' x1 q1 ?/ q, f/ @2 u: L) i2 A, i* H4 P
Loads are processed by each operator for the following time:
* L3 |2 N0 |7 Q; U; Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& s% I d% P2 v9 |. Q# o$ Q" t
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.4 y; x B+ S- R# Z2 j1 z% W2 A, }
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 i7 v, Y, c% r8 @! R; T6 }2 K+ M7 sSend 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.' k4 J2 |, N$ J0 c# u
+ K; ]" x0 J$ j' t# \问题:2 x h% z0 ]5 [' ?( T0 t
After running the model for 10,000 days, what was the average number of loads in each process?! _# l0 N/ l% h6 W7 V+ b

不胜感激! |
