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,
+ G+ v0 Z! z4 u5 u, |. U 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' o+ p9 z9 _; w
Loads are processed by each operator for the following time:1 o! a* H& ?7 g& l& `
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 C: J+ ?& _1 Q
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.
7 Z; v1 \; q+ } a( t' [7 N/ h Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 N5 z }& m/ c" F! j# g- G1 I/ m
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.1 ~5 I2 _" i$ E, W

问题:
H0 X9 M( E! X b7 bAfter running the model for 10,000 days, what was the average number of loads in each process?
