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,
! y; B7 f0 v; P. n0 ]( h) Z 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.
/ S0 a* K7 U7 P4 t( [' y3 w# M% S Loads are processed by each operator for the following time:9 B- O( ]( _$ w, F r
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& N w9 T6 H2 E7 e I: n 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.& |- t; I! c7 b
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, e1 T8 R. s* A$ {7 }5 nSend 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.0 z9 j' a+ }% c; A5 {% Q

After running the model for 10,000 days, what was the average number of loads in each process?- {2 m9 u. p, O5 A# R- f
