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,
% {4 S1 F+ z+ ~; C+ q5 Z1 G3 ? 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. X, Y' f; U, B5 f+ y* f8 Y; v
Loads are processed by each operator for the following time:
' V+ g1 ?: D- V. J8 h) e; w* T Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* Y( n' P8 o! N. v4 [ \# 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.0 N0 V5 v& a; s
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. H0 U$ v9 v+ O& H1 r+ i; bSend 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.! J) ]3 c& S/ E* [' \# d

After running the model for 10,000 days, what was the average number of loads in each process?
