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,1 ~# N$ F# u) v t
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 R- {$ A# U( S
Loads are processed by each operator for the following time:
5 ~5 I( o N% E& B1 Y8 W9 [& V, O Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 s% W9 d/ }% l1 ^! i5 ?$ 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.
9 m% A* y9 {- e- W/ v1 u$ L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.; N, J7 {+ t E M' _: X) 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.
