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,# o9 R* j- Q' n. \& h, u
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.
/ k3 W, Q+ S- G, y2 |1 m Loads are processed by each operator for the following time:
0 M0 ]. Z2 X J0 G; ?5 f) `7 J: H Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 v9 u: E u) H1 T. {5 U+ 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.
3 i6 q3 j$ x) w/ F6 R Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- ~4 M, Q% j' }: qSend 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.
