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,; y+ l& }2 _0 ]* s3 M
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.
' A2 v0 R$ s; m5 ~ Loads are processed by each operator for the following time:
' p2 H0 x: M4 H$ Z2 y Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: P: R8 F+ T3 f
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./ b5 Q& X2 ?1 n
Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ r6 q7 Y! m9 \/ s9 V
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., K5 r% n+ f5 _, q. K- q
