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,
+ j$ A! S$ D- D5 v' `: } 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.6 o U- H$ \2 C- f5 J- S6 v
Loads are processed by each operator for the following time:
) g: g% C3 h$ N3 b Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* C+ V& Q6 S/ z7 s$ F 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.8 H2 Z/ `3 P7 a1 e1 ~
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 @2 i* H! ~' T. H" g+ gSend 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.: u5 C& z1 n& J: G0 |" a, r# \
% \8 I" p1 T, X$ \
问题:, E" u# V( a# H- k
After running the model for 10,000 days, what was the average number of loads in each process?- k+ V! f* O' i( w0 g$ @) L
