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,
9 O/ A$ r, C2 N* t3 j* s9 O3 d 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% A3 k- v" e$ W$ T$ k
Loads are processed by each operator for the following time:0 m* @7 {) I, ~) \8 I2 \* u
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.9 ]4 g; Z, x8 g
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$ E" |; K) Y) c
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" d+ O' o& y/ f, e2 tSend 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.
