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,
A" g, ^" b- S; J! A7 A) 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.+ E# ]0 C; E3 \7 y& e; j$ f
Loads are processed by each operator for the following time:
; ?/ r& C) x6 B6 o i, E Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.1 O# d" r' a% J8 v; C
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.0 g# B, Y7 T- N Z- Z) i3 U2 ]
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.- x6 z2 n6 |$ P/ P* o @2 Q
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.
