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,
2 ?5 N+ W+ B, b7 O- ]0 Y2 w 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.
. {" j, x" S, {7 L8 W0 ` Loads are processed by each operator for the following time:% b/ M3 B2 Q6 F; t6 u/ V
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* B* ^) b# k2 @ J3 o# m- O" s" W
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.0 \: K" Q$ s Z! ~9 M/ A6 @2 T0 r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 }+ V; v4 H9 Z0 qSend 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.
3 P+ P- T9 V! C# U, F7 F# o* G" I2 Q! w. r1 D: h' m( ?
问题:
( {2 X/ H5 b5 \" CAfter running the model for 10,000 days, what was the average number of loads in each process?
