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,1 r7 x" K! V F) z3 D
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.
: G1 q$ g& Q% }) A( r Loads are processed by each operator for the following time:- H& |/ }2 I. I& |; Y) p4 n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., Y7 N- S O1 a6 X( x- e
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." H r9 S0 W$ E+ w" X, Z' `- v8 T3 g
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, z7 u7 I$ l: R( u5 |: s* X+ DSend 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.
