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,
% i5 E0 ?! H2 H; ~8 @( g1 R 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.- V' I+ M$ f0 ~; x0 _
Loads are processed by each operator for the following time:
; S; R* q( z" C: E/ A3 }( a Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." [. X; t3 i: g6 _) N/ U) 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.! R# }( _7 ^) J3 i& D
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( B, d* m) V) P n. `
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.
! u9 r7 X+ o4 `, s9 R" p f# n+ y% F/ D) W& c
问题:3 w# C8 s0 f! p5 ^! R( `- h; J# _" w
After running the model for 10,000 days, what was the average number of loads in each process?
