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," e V2 i( F% c) H+ [) d5 f/ r+ |
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.) `7 w# x. R. W1 ?# u
Loads are processed by each operator for the following time:0 I" u; _+ |6 h7 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 S! F( a( r# d. B" }3 h9 U 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.
