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,* Z' h" K1 L/ Z9 d' n* l/ q
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 u: g% i9 A! Z- F$ @
Loads are processed by each operator for the following time:
' w3 k. o, D6 X; \, O e# @ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. \4 J; ^, g5 T6 ]1 P% J 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.
0 h& L' s. P- E% r( T& m Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 Y' q8 F9 l. T# f- n
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.( X8 H m! x2 F% N ?0 G0 v; z: B4 Z

问题:
