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, r+ E1 b' X5 E4 G3 }9 f
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.
# h k2 j. x9 e- U5 ~! }( \$ Y Loads are processed by each operator for the following time:/ c2 `: O' w1 }$ @3 u& d) [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ x- M- e% \) }0 x2 \2 E: r0 j* Y
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.
! ~- k8 L3 W$ D5 l4 U Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 A7 N: P1 y/ k5 N8 u3 Z
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.7 r0 I# l" c- I0 C6 l# ^) a; e! [

After running the model for 10,000 days, what was the average number of loads in each process?1 P- ?$ @ {9 A$ U& J2 [, j( J
