This paper describes the dual use of a case base for diagnosis and for improving the design of a manufacturing process. In the short term, the case base is used to provide past experience in dealing with similar problems during the manufacture of aluminum components. In the longer term, it is used to feed that experience into the design of the manufacturing process for new components. This is a...

Failure mode and effects analysis (FMEA) is a widely used engineering technique for designing, identifying and eliminating known and/or potential failures, problems, errors and so on from system, design, process, and/or service before they reach the customer (Stamatis, 1995). In a typical FMEA, for each failure modes, three risk factors; severity (S), occurrence (O), and detectability (D) are e...

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 simultaneous generation of steam and power, which is commonly referred to as cogeneration, has been adopted by many sugar mills in India to overcome the power shortage. It becomes an increasingly important source of income for sugar factories. The problems faced by the sugar mill industry arise mainly due to failures of either the complete system or some specific components during the cogen...

An important part of the quality management system of the company is to establish procedures for quality planning. The sense of quality planning is in the prevention of either construction or manufacture failures, respectively their causes. Nevertheless it is a tool to increase the likelihood of early detection. FMEA method – analysis of possible failures and consequences (Failure Mode and Effe...

1. Introduction As the types of defects that are causing small leakage currents are more and more difficult to find with decreasing feature size, more advanced analysis strategies have to be developed to meet reliability demands. A method based on a delta Iddq test has been developed to sort out parts with potential reliability issues. Those parts are fully functional, but show small Iddq varia...

Safety critical systems are those systems whose failure could result in loss of life, significant properityda mage, or damage to the environment. Brake-by-wire (BBW) technology in automotive industry is the ability to contr ol brakes through electrical means. It can be designed to supplement ordinary service brakes or it can be a standalone brake system. The increasing usage of brake-by-wire sy...

Radical Maintenance (RM) takes the root causes of failures as executive objects to make maintenance decisions. A Root Cause Analysis (RCA) is carried out on the function failure of equipment to performRMand to create a maintenance plan using the combined methods of Failure Mode, Effects and Criticality Analysis (FMECA), and Fault Tree Analysis (FTA). Evaluation criteria andmatrixes of criticali...

prevention of medication errors in neonatal intensive care units (nicus) is of paramount importance due to age-specific and physiological conditions of neonates. this study aimed to evaluate the risk of medication prescription and administration via failure mode and effects analysis (fmea), which was carried out at the research and medical teaching center of imam reza hospital in mashhad, iran....

Abstract In this paper, we propose a bounded DEA based model to measure the overall risk of failure modes. In the proposed model risk is measured within the range of an interval, whose performance is definitely superior to any one. The risks, obtained from bounded DEA models, turn out to be all intervals and are referred to as interval risk, which combine the best and the worst relative risk in...
