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,
: ]: y$ p" V, {" q 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.
% P1 J. G7 t" O& S: s Loads are processed by each operator for the following time:) y0 j/ h- H$ D
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.& Y, o/ e* n! D0 ?" { S
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 `' F7 ?$ n: o% b
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( \1 }1 ~( p% w& U' s1 Z( j
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.8 v, t4 C: p# ~3 Z! c1 S' ?8 x8 n
# L, f3 _! r; V: X/ m问题:' z( ~" l3 v Y2 T! F: K" z! e
After running the model for 10,000 days, what was the average number of loads in each process?
