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,- F6 ?5 P; c: X, Q" p$ X
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.
! F' e y' ]8 c! d$ m( @8 F4 P Loads are processed by each operator for the following time:( n9 ]* C7 J& K1 p% O0 X5 v
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' T. p2 U0 V1 \& }! @( M1 s3 _
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.
4 F' e& ]" h: X' q Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
0 L, F% h9 l9 }1 c# h* qSend 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. p. Y S2 k% z
