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 [# X' Y% Z5 T! r1 S
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 L2 g1 ]8 ^' H* h% ` Loads are processed by each operator for the following time:, D; N6 {7 G) u4 [
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 j5 r, e: q, g+ o6 R8 x! w y
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.4 u2 `4 j# p1 J! v
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
