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,
) I, f% Y3 Q; b3 F7 _( j. L; P4 d 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.
L/ z, J# @: t4 m' j6 M4 @, b Loads are processed by each operator for the following time:$ S8 m( z% y7 Y$ }
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& Y6 x6 `# }& _+ _. k 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.
: s% j! [5 J/ W# A9 G7 L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( P7 S2 ?; r+ W0 ISend 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.
. p: |! T3 m! x; d! W7 \- `
# ?' T% V2 G" V# K7 U问题:. h( d* g4 F) C' J$ H9 b
After running the model for 10,000 days, what was the average number of loads in each process?
