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,
4 T0 N9 ?9 w0 m/ Y5 z) T& ] 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.- N. J5 R* h5 A( |2 ?; z t
Loads are processed by each operator for the following time:* }: n7 n4 F1 H# h: M2 M; T
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 p) @; ^$ U7 C8 c- x% Y- _ 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.
( r2 b9 s' k v! p, X Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, g6 @' y: t- e# g9 E; k* vSend 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.! |* g$ o7 X0 u
7 Q) I4 V" N2 o8 D: J' `9 o8 ~
问题:% Q1 o5 N% N* G# i$ Y; o, W3 K
After running the model for 10,000 days, what was the average number of loads in each process?3 j5 r- J$ \- r
3 B) P4 Y6 Z- i5 h5 F3 n9 D不胜感激! |
