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,
* n& ]% a1 }' n% 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.
, g3 G0 m: ]4 y! E Loads are processed by each operator for the following time:
# m% i( ]# T) P1 z d; p Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* A& |. f; }; B. }0 F% D 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.- M7 {9 u, s3 E2 P; F- \
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, z) a- }, U& l$ G3 |" R2 H7 oSend 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.
