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,
& x7 i9 v5 b8 O. g* B8 m4 y 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.! z+ P6 l" `; D. n0 `3 b
Loads are processed by each operator for the following time:) M+ i6 i+ T1 h5 Z; g' C2 U
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.0 j1 m( k6 _( r+ n# {, Z+ ~2 U( ~# K
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./ c0 }" N( a7 L
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 j; s+ W# q9 B9 c2 X+ w, N
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.
% e! y/ S9 [% U8 n' l4 p+ n O8 L! `0 {: ~
问题:
