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,
/ B1 Z1 |% O$ E 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.
, u; }* }; P) M7 x& C ^ Loads are processed by each operator for the following time:
, d3 p( `2 C( _' @1 K `0 b Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., p9 s6 M0 G2 a( _% k* Z2 B' C5 J
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 h9 ?+ H, z% c+ h# g" J
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 A( \0 b1 }4 u v8 [( D0 n) FSend 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.
( R9 \/ R0 w+ b' o2 y" q! h+ f
