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 [' A+ e" \" B2 M! i6 r d$ i 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.$ b9 x& ~1 u% d: E" L, P8 L, E
Loads are processed by each operator for the following time:3 V/ U& v3 G. y
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.2 }& K4 `6 [# Q
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.
) G) `0 S. j+ Y7 v8 L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" P/ c& H# ~) b i( }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.
