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,% u3 Y& }2 ^( Q. j
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. I' U$ P; A" g# c# t0 K- L1 @
Loads are processed by each operator for the following time:+ P5 R8 F' C7 J+ [1 j% B7 f6 R6 o
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
( e: Z! w& A$ d 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.
/ l* }: Y& {( n, A: Q! a& f: c Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& L+ o7 O2 a4 ySend 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.
