Abstract [en]

In order to make the product more reliable and efficient, the failures and their occurrence related to the products should be reduced if not eliminated. To achieve that, the approach of Failure Modes Effects Analysis (FMEA) is used in the process development phase where all the aspects of the product failure are generated and studied. With the passage of time the systems began to become more complex and alone FMEA not good enough approach for the complex systems. To handle a complex system is a hard and tedious job which requires more expertise. In complex systems the individual system might have overlaps, their boundaries are often unclear. The computation of information and its transmission between the components is extensive. Object Oriented FMEA resolves these issues by identifying the structure and screening a proper boundary of the system. It looks deeply in to the operational environment and external shared resources. It then decomposes its functions and behaviors in to separable physical, logical and attributes objects. The OO-FMEA approach obeys to the objectives of modern product development process and its principles. This approach makes it comparatively much easier to analyze the complex auto-motive systems that are built in extensive electrical architecture. The systems components perform their task while being interacted, linked or even independent. In this thesis the OO-FMEA approach is implemented on the Climate System of the SPA Hybrid.
