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$ Q& R( u: g3 f, G; C& U* Y 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.3 X) b- D1 U; {) k1 y8 W
Loads are processed by each operator for the following time:
8 b( E8 G7 a4 c) |9 ^% L Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 H, }% ?/ N# n- a
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.
4 i3 v3 U4 J: y4 |2 k+ t, g* n Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 h& K$ W1 |( l! r8 \
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.
/ [, N: w9 x0 Y# B7 [

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