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," Z4 P7 ~, R m% O- J4 a7 g R8 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.; s, `/ Y3 A, T6 k8 e" ~( _% j
Loads are processed by each operator for the following time:
/ _3 d, _( G3 U* r5 u Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
H; u3 @% u3 e/ m 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.6 p/ n6 _* T/ @- I' }; G
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 B9 i7 j0 P, N9 H
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.
% k0 F+ H' {; u, b- \+ C3 O$ a# {3 V( N- s- X5 ^1 v/ m
问题:& Y7 m) m4 Z$ Z2 C2 _: s4 ~. t* n
After running the model for 10,000 days, what was the average number of loads in each process?
