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,/ L, B, k% T, A' i9 [
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.
) P' G9 E6 R. ?4 I" ^ Loads are processed by each operator for the following time:, f9 X" [8 Y, Q8 S
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.! A# B) L3 }+ f3 s W9 E
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.
# L6 r7 e2 ?; y o% d' }3 W Worker_C does the job in a uniformly distributed time between 30 and 90 mins.3 R$ p. y$ p, F) @
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.

问题:
