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,0 h# H* B) U1 \9 F9 S O
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.6 {; l" w% }2 T& M& G6 t8 U9 |
Loads are processed by each operator for the following time:
u0 \9 T! c8 e3 g Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.4 H- J8 n: X* E/ g; s- L9 B
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.
j/ M4 c: c7 y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.9 z( e: j$ s# r2 M: v2 Q! X2 S
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.
