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,
+ a4 ^# I% I5 a 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.
5 w0 E) y) m, q/ i6 M% S Loads are processed by each operator for the following time:) Y: _ g- \" l* |
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# @) |' N2 z1 |! p3 m 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.
, [: t+ X0 \; ]. B- g1 u2 p Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 Z8 @0 }: _* i# ~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.
0 ^) g9 A4 a( z, Y) C, ~8 t
