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,
* Y4 ?0 ]6 ?4 W1 C2 B l 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.
/ G4 O' T! M$ V5 E |7 ~ M7 P Loads are processed by each operator for the following time:
* O t7 n3 C5 c8 s4 X! t. z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 O+ I% W$ G4 d* E, n 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. s* l$ C, T2 C- _
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 X# p# m" X; Y tSend 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.
