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,/ m1 Q) ]0 Q# C' X% I( X
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.2 I5 V6 @; ~4 F/ G- k' d
Loads are processed by each operator for the following time:' ~2 u. z/ j: v, U
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 [1 s; N6 J) 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.
v1 `" B! ]* \) d; c$ T3 C Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
* H6 d' m7 X% R' Z: xSend 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.
