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,5 h' g0 l! d! 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.
9 _4 s) g' U; S" w Loads are processed by each operator for the following time:0 y% `6 \0 [+ V( L, n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- t$ v2 _' l6 j, L
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.

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.
