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,
, i) B0 f D0 ]7 K4 D7 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.
( i" |$ s0 ?4 a ~# A, _! F Loads are processed by each operator for the following time:0 u6 V$ n3 _. {" ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.$ X. q) {* {, [! G% ?3 p; B
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.2 k# A: w* o1 e% f# I. f
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, m$ M) ?3 z; G0 `) P! b2 ]$ ?( J& qSend 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.
