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,; h/ T  F" P/ I* E: Y9 ^
  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.) C: [3 |+ F" @1 o
  Loads are processed by each operator for the following time:
* B& R* M# F+ G/ E3 p$ O+ q' `5 `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
, c7 D+ w4 H4 E) s+ d' l" _5 ^- }  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.
% H/ ]3 D% N/ t: Y, g  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.( ?  q, A: I; ]. |, z
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.

Remember to turn off the animation before you run your model.
