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,
: L$ c/ V, n' B, f% x. m; S4 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.
1 h# D% l: [& Y- y2 Y6 a8 K Loads are processed by each operator for the following time:
" i2 i" C M# J0 e; a1 P( W. }1 Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ W( ~; c' I/ T% N 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.! R4 }8 [$ h2 U8 a$ z+ O
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 r B5 i" U1 |7 X, R' R$ i% vSend 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." E/ I% g3 u; z0 I# m$ e; y( D
1 b- D1 \3 \4 V+ q; @2 R! c问题:
. D% k4 [8 U! WAfter running the model for 10,000 days, what was the average number of loads in each process?
# T0 H- y. _, H; b0 G$ S u) n5 D' s7 l3 u$ M$ T
不胜感激! |
