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 Q3 c" T d3 }
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.5 E/ T( x# T' J" p+ E- T
Loads are processed by each operator for the following time:
% V ] H# ]. v2 @0 v$ ~# c Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- i: T8 a5 H) F. q# M I# G+ t
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.3 G) K/ o+ ^( w R+ p
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( Z S( y+ E% n2 l1 F# V& }( y& d
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.
& @' o4 F* W2 n- S5 f" n- T( s. P) `* u6 m2 N& W! `; h% X, ^

After running the model for 10,000 days, what was the average number of loads in each process?
