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,7 `% E3 {% x9 d. @
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.
$ D0 U( ]0 o1 J* c0 T7 K5 N Loads are processed by each operator for the following time:
0 _/ o! h# B( Z9 Z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) F- \ D `; W4 B- q" p 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.
& i/ d6 Z' m5 g$ ` Worker_C does the job in a uniformly distributed time between 30 and 90 mins.& o7 |) m3 t( ]" x: X, p0 T
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.
