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,2 o3 n3 A! b* f
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.
8 n+ O' U5 t: x# Z; f& q, i1 z Loads are processed by each operator for the following time:: T- x& g2 z# Q9 N- C1 P( {" Z/ e) E
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 [* \5 F, N% Z" A- ?# T9 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.
( t7 D& d1 u% ]3 t# Q% i Worker_C does the job in a uniformly distributed time between 30 and 90 mins., ^9 ^& j" b9 Q- ~0 v. Y1 x
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:
