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 y% N0 m! T" p' u0 ? 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.. R- ]7 d7 H) e$ v& k2 w
Loads are processed by each operator for the following time:
T" b1 |3 D% [ R8 D Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: v9 a) h5 _" ^6 S2 F$ j8 v 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.
, g( `' m: X5 ` Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( v& @: p4 W( [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.6 Q9 j4 k8 h; w( M
8 J3 N( G) G9 @7 Y) s问题:, s3 D. A5 D8 V c$ ]2 Y# I
After running the model for 10,000 days, what was the average number of loads in each process?' f6 G# y3 H* x/ }
