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,
' x( j( a& }7 v/ ?! |0 t 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.
T8 |, L7 d' w6 r. u* ] Loads are processed by each operator for the following time:
" G0 I% c( m& n( V; ^7 B1 N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 v8 C$ Q! Z: _ e( o) y/ i6 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./ i' z A. G1 j: F" E. r' U
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" P% {% a2 V) g t, ^8 sSend 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.
