This paper presents an industrial application of “Dysfunction Mode and Effects Critical Analysis” (DMECA) to determine and analyze possible dysfunctions in a complex management process. The approach conceptually derived from the Failure Mode and Effect Critical Analysis (FMECA) technique. DMECA enables user to analyze all possible dysfunctions of management processes, identify the subsequent ef...

This article presents a Decision Support System which focuses on an important organizational context: maintenance decisions. Usually, a specific management system is required to deal with data on failure, reliability, maintainability and availability regarding equipment. The maintenance context is surrounded by uncertainty and does not provide a clear profit from its activities, and thus requir...

The goal of the FMECA (Failure Mode, Effects and Criticality Analysis) process is to determine the consequences that failures may have on the function of a complex system. In aeronautic industries, this process is very important and must comply with international standards. Today, most of the process is performed manually. This can be problematic, since, although the basic process is not diffic...

This paper develops a Failure Mode, Effects and Criticality Analysis (FMECA) for heating, ventilation air conditioning (HVAC) system in railway. HVAC is safety critical which must ensure emergency case of fire loss primary functions. A study the HVAC's areas mandatory to optimize its reliability availability consequently guarantee low operation maintenance cost. The first part describes FMECA p...

Recent regulatory requirements for shipping emissions control have led to the adoption of Liquefied Natural Gas (LNG) as a marine fuel and design LNG-fuelled vessels. Considering potential safety implications due system failure/unavailability, this study aims at analysis low-pressure LNG feeding using novel model-based methodology. The proposed methodology is based on functional modelling, lead...
