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,
, V. d, Q3 d' W! y! Q4 H$ n2 U 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.( L+ d- I4 J3 K$ S
Loads are processed by each operator for the following time:
8 c5 D! `$ q; F( v5 g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! N# u8 R1 L# S' d& F9 q$ g! 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.
! \! b/ } {: f8 m; T+ c+ \( d2 a: y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) `* k0 Y0 L" \+ P6 k- jSend 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.
