mat#ematical models to select discrete ords or com%lete %#rases 5#en used for

In my o%inion, using discrete s%eec# in my %roect could be more efficient and reliable

(ecause informing t#e residents it# a correct message is our main goal So it# t#e ay

It is clear t#at %roducing a loer cost resident informing system is not a difficult %rocess

T#e im%ortant %oint is using t#e suitable de&ices and %roducing cost effecti&e systems If

e remember 10 years ago, %roducing t#is )ind of de&ices and systems ere so difficult

and e%ensi&e because of t#e insufficient softare infrastructure In t#is direction, t#ese

articles #el%ed me to understand t#e &arious systems T#an)s to t#ese articles I #a&e

found c#ange to analyze and com%are t#e systems t#at are used in today4s orld Some of
