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& S5 V1 r/ t* r k 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.
3 m! i1 B) c# O Loads are processed by each operator for the following time:
' |: E0 N, \8 Y8 E5 Q2 ^ Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
D! S5 H' D0 ]+ K5 n 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.
t3 t7 r1 X# s) n, _ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
6 O- J% r7 _, ^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.
