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,
. A5 c9 {) M: r- S$ E9 K 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.
6 n% |0 s s5 ` Loads are processed by each operator for the following time:3 @7 Y9 J }; Y; o: @( \6 r
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 K: x: U5 S1 Y% w7 b
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. |" Q8 T8 F7 l1 }
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
9 b2 Q1 u& u& z+ t, Y. m! q, ]8 VSend 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.5 o$ [/ [8 V/ ?* |$ h
