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,
, o m5 U; n4 F/ z/ ^4 W0 E. v2 S 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.. k8 t1 _' i$ m2 }4 K$ |2 l% ^6 q
Loads are processed by each operator for the following time:( ~/ W9 f0 Z' N+ U
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 W+ U8 I+ @% o) W: G
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.. C! T$ K/ h, R! [6 y/ S2 ^ k0 I6 O
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* G- W* t2 t1 W3 L! _0 M' Q: c& b
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.# ?' e2 z% w; p) K% ]7 G3 K, M
