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+ j8 n' Y4 t0 s3 j
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.) O2 b7 ?* i H4 ]
Loads are processed by each operator for the following time:
7 f& M5 ^$ P+ ` Y) f Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., M! U" d6 m( I8 G: n. b
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.
+ y+ r( V4 t! F; Z" Q7 @1 Q' L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: c$ t% U4 ^: b7 E: KSend 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.& J1 ]( a+ t( S1 Z% F
: a& ?, X J1 h, e" _! I0 s+ s e问题:" a( o5 U# `# A9 F+ l
After running the model for 10,000 days, what was the average number of loads in each process?
