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,
8 U% h7 ^* x; J% K 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.+ N- [7 ]. w+ d! n
Loads are processed by each operator for the following time:
0 v( g$ z( E6 v! a# w Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
/ S( ^* o9 t0 G* l* p! N) U 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.1 l1 L# j- v3 C& n% i, X# y6 K
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 b: z9 w7 z* d( k" V7 E, ]5 Z
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.
) K) I5 G. L3 a
) i8 [% G1 R; j% Y/ Y* i7 n$ c问题:0 g0 l0 M7 c, H( d; X
After running the model for 10,000 days, what was the average number of loads in each process?6 Y- @+ \- ?% i' n' \( f
. M8 f0 H; K7 y& ?不胜感激! |
