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,6 |5 q) W& p L0 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.
3 M5 T# H% V% ^/ q1 r Loads are processed by each operator for the following time:$ m" f: H& Q- C* a: {4 Q( ~
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
7 D7 I) z8 c( g9 w/ w' M1 {/ K5 O 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.3 Y* T, ?4 c. E/ |$ L+ N
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 s) V* f* {% j# B6 U8 m- a. dSend 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.
