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,
6 M) S2 i6 P: t 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.6 R/ j9 y. Y5 g4 r2 b, D
Loads are processed by each operator for the following time:
4 w g- \9 V9 H3 |) I U Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; a, q" _0 X* |* X8 P) { 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.! D$ z! F- T6 F% Y# s) c( e
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.' n/ ?: e6 u+ H
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.
9 C- L- N0 H9 x! c6 S9 j8 g2 V! c" X: c: L. \, s0 z
问题:0 h, O* Y1 Q0 \4 @# a ~, {* }
After running the model for 10,000 days, what was the average number of loads in each process?
