Functional safety analysis (FSA), that is checking whether a designed artifact will perform safely even under the presence of failing components, has gained significant importance in different areas, including aeronautic and automotive systems. The same applies to failure-modes-and-effects analysis (FMEA) and fault-tree analysis (FTA) as the major contributing processes. FSA is laborand time-co...

This paper presents fluid flow system simulation using the MCIRQ qualitative simulator. MCIRQ was designed as an electrical simulator, however this work exploits the close analogy between fluid flow and electrical current at the level of qualitative behaviour. The core qualitative flow algorithm is applicable to both domains but there are differences in the systems structures and assumptions th...

To ensure higher reliability, it is necessary to identify the most prominent cause of failure. It was observed in multiple works that researchers used failure mode and effect analysis (FMEA) criticality (FMECA) but these approaches contain lots hindrances. Alternatively, MATRIX FMEA approach applied critical sub-component prone particular The matrix developed for design engineers so they can po...

The growing competitiveness in the automotive industry and strict standards to which it is subject, require high quality standards. For this, tools such as failure mode effects analysis (FMEA) are applied quantify risk of potential modes. However, for qualitative defects with subjectivity associated uncertainty, lack specialized technicians, revealed inefficiency visual inspection process, well...

Service companies must be able to face the challenge to offer error-free services to their customers. According to Service definition, the customer is always present during the processes and delivery of the service . If something goes wrong it will happen in the presence of the customer . This article shows the use of FMEA as a prevention tool in the services offered by a Medical Clinic restaur...

The paper aims to introduce an approach that integrates a technique of knowledge engineering (Ontologies) and a technique of quality engineering (Failure Mode and Effects Analysis). An approach will be set up that shows the potentials of combining IT-based systems of knowledge and quality engineering. Particularly with regard to the quality engineering technique, the paper aims to demonstrate t...

The advancement and proliferation of information technology has made it possible for specified functions of systems including safety-critical systems to be software driven. Traditional failure analysis techniques existed before computers and are widely used in the failure analysis of hardware. Typically, hardware failures are random while software failures are systematic and this makes software...

Quality function deployment (QFD) is a customer-driven approach in processing new product developments in order to maximize customer satisfaction. Determining the fulfillment levels of design requirements (DRs) and parts characteristics (PCs) is an important decision problem during QFD activity processes for new product development. Unlike the existing literature, which mainly focuses on the de...
