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,
) X6 ^! U3 D( O0 w 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.
, A( q g( u, \ Loads are processed by each operator for the following time:
6 [3 q4 l2 j0 y2 w8 ~7 O/ A Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% G* ^( |: `- _8 I, C 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.! w X& b$ m+ e, V/ H; F6 n1 |
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 |' f9 p% h$ Q( t" C9 V# bSend 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.
