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,
% { c# V. h: b/ p) t, d' {1 q 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.) r) h3 j P; q+ S, j; w- u
Loads are processed by each operator for the following time:
/ ?' q* K+ k+ A; U# ~. z5 Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.8 I' n* A+ Z/ F* g# F) D
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.
5 F) K, h) [. w6 |" } Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( ~" i3 s4 T r
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.
7 A! Q0 _, \0 F9 Q7 b5 I( Q" t1 E5 z0 Z/ P2 H
问题:
& z/ Q8 X+ F) A% ?After running the model for 10,000 days, what was the average number of loads in each process?% l5 g+ q. ?1 \( N1 r" q9 D2 m$ ~
) m: n2 X: f4 T* s- R
不胜感激! |
