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,# J" Z. h6 r5 f* A8 {
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.
4 B* K( R4 S6 k% t4 D Loads are processed by each operator for the following time:
: t2 M) d s } Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.3 T$ @/ y9 ?8 D7 A, N6 L" V0 Z
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./ Z; o& r. k9 I+ \4 {3 q9 i% `
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.: r' j: o& p( v' O4 K
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.0 i1 I; x& L) Z
