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,
) q+ |4 K9 A! e0 m+ \  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.* r/ L: r8 Z- {( v5 x
  Loads are processed by each operator for the following time:) H% }+ o# d2 j2 V) o
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' T  V3 C+ D2 f/ {" Q
  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.) ?0 U- v+ _: l8 t( E- P( f+ |
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& W( ?, i, A6 G3 v. a' ]2 @9 _9 ^
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.
