Security systems are necessary
everywhere especially in Banks, houses, offices etc.
An RFID, GSM and Keypad Lock System is a
multiprotocol device designed, constructed and
customized to combine the security feature in
RFID, Global System for Mobile communication
(GSM) and password for the three components of
access control which are identification,
authentication, and authorization. The device was
a series system (a failure of a unit result into
failure of the system), therefore reliability analysis
was conducted to reduce the failure rate using
Failure Mode and Effects and criticality Analysis
(FMECA). The aim of this paper is to present the
reliability analysis of this security system. Each
component/unit will be analyzed, depending on
the degree; numbers were allotted for severity,
occurrence and detection, and subsequently, the
risk priority number (RPN) will be obtained for
each unit and subsequently for the system before
and after an action to increase its reliability. With
the reliability measures, The result obtain shows
that the severance of the system reduces by ~16.4,
occurrence by 50% and detection by ~11%. The
RPN also reduces by ~ 68%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
