developmentof fault free systems and theirrisk assessment, in early phase of development were set in 1950s, which later on used a standardise techniques for safety and reliabilityissues in products. failure modes and effect analysis (fmea) introduced as oneof them and still considers a much reliabletechnique to identify and mitigate risks in early phase of system designingeven though systems become complex now days.this report presents an extensionto failure mode and effect analysis (fmea),in such a way that it can be appliedfor safety analysis of complex systems; both for hardware and softwaredevelopment using object oriented approach.

a systematic approach for validationand identification of failure modes were used in this method using systemarchitecture; a complete boundary diagram with the behaviour of the system inlogical, physical and attribute objects. behaviour of selected objects wereanalysed using fmea methodology with the help of system designing team, wherevalidation and verification processes highlights possibility of redesigning ormodifying component. cabin cooling system for hybrid vehicle is used as a casestudy for this purpose.

upon authorization of the proposal, i will proceed tothe next stage of the research. that is to say, i will do the collection ofdata. it is expected that this process will not exceed one-month period. afterreceiving all the required information, it will be interpreted and analyzedsystematically to draw out a conclusion. it is only after everything will beover that i will start to write my report. this way the final draft of thethesis is expected to be completed.
