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,
& N/ Y( b9 N# r! m" T& {6 ^( J 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.) h( B" W4 p! E
Loads are processed by each operator for the following time:% q( o. ~! m5 ]# X
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ p& q; ` f% p5 }, `6 m& ?2 A* T
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.- ^5 n% S6 F9 u) U* R0 A" d
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- v3 ~. ?" V1 x* N6 KSend 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.
; J U1 d: E- V3 c5 h& {+ _' ?5 q% `. I: @. A2 n
问题:
