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,
d# L% V& u) w 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.
" q p' [9 C2 r( [ Loads are processed by each operator for the following time:
; W/ @, H" D$ H* k$ s, q7 R Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( I0 J* e& j& M4 b- u7 g
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." J6 v" K" }$ I8 A% y
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
5 Q3 o- U" I. WSend 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.
