Failure mode and effects analysis (FMEA) approach is used by most of the methods of risk assessment. There are majorly two types of FMEA: process FMEA and design FMEA. Design FMEA involves activities in designing, such as service, machine or product design. Process FMEA deals with assessing the weaknesses in manufacturing process and the effects of failure in process on the manufactured products. The most important goal of FMEA is to allot the limited number of resources to the most critical and
Introduction Reliability-Centered Maintenance (RCM) is the process of determining the most effective maintenance approach. The RCM philosophy employs Preventive Maintenance (PM), Predictive Maintenance (PdM), Real-time Monitoring (RTM1 ), Run-to-Failure (RTF- also called reactive maintenance) and Proactive Maintenance techniques in an integrated manner to increase the probability that a machine or component will function in the required manner over its design life cycle with a minimum of maintenance
FMECA or Failure modes, effects and criticality analysis is an extension to the FMEA process with the addition of a risk (criticality) assessment. FMEA analysis is required by: - Classification societies as part of the acceptance criteria for IMO Class 2 and 3 type DP vessels. - Charterers to know that the vessel is fit for purpose. - Owners to satisfy a charterer’s needs and to give themselves confidence in the safety and robustness of their operations. - Operators to know how possible failures can
In this modern era, high technology equipment is required to ease employees’ workload. Surabaya City Government has 69 Satuan Kerja Perangkat Daerah (SKPD). In Rencana Pembangunan Jangka Menengah (RPJM) 2010-2015, Surabaya vision is to become a better Surabaya as Service City, smart trading, humane, dignified and environmental minded. Aligned with the vision, as a city that prioritize high service level to its citizen, it affects the necessity of equipment in government offices to support its activities
The authors (2014) state that mode refers to the way a product or process could fail, while effects refers to the consequences of the failed process or product. In addition, FMEA is an inductive method that is designed to recognize and evaluate the potential failure, effects of failure, and the actions that should be taken to reduce the potential failure (Fibuch & Ahmed, 2014). In the 1990s, FMEA was introduced in health care as a risk management
The frequency, in which the term complacency is reported in the analysis of aviation accidents, compels the necessity to examine the possibility that automation induces complacency. Over trust of automation is something referred to as complacency. Complacency can lead to a decreased monitoring of the system and a decreased likelihood of detecting system malfunctions. In the incident investigation ASTB AO-2014-179 conducted by the Australian Safety Transport Bureau (ATSB), the findings of the
citizens with in the utopia. The failure to invent a quintessential environment morphs a utopia into a dystopia. People who are a trying to enact a change use causal analysis, a process that inspects a cause and all the possible outcomes of the change. After a change occurs the creation of a utopia or dystopia is dependent on the correct use of
the development of progressive collapse analysis and damage valuation methodology of partially collapsed structures. The purpose of these expansions is to increase the safety of people in structures subjected to unusual loads. The developed analytical methods will support engineers to predict the type and range of probable progressive collapse in both the proposal stage and after existences. This is the main reason to connect a progressive collapse analysis with a structure identification procedure
construct an integrity assessment procedure on pipe bends, significant researches were carried out both an analytical and experimental approach. The results of examinations were included in terms of stress intensification factor (SIF) for piping analysis which differs for both in-plane and out plane bending moment. In the manufacturing process of inlet pipe bends, it is difficult to avoid thickening on the inner radius and thinning on the outer radius. The cross section of the bend becomes non circular
A review on vibration analysis of crankshaft Abstract Crankshaft is mechanical component with a complex geometry which does the transformation of reciprocating motion into rotational motion. It converts the reciprocating displacement of the piston in to a rotary motion of the crank. The life of crankshaft depends on its strength to wear stress and loads. Any defect in the crankshaft (e.g. cracks, notch) deteriorates the performance of the engine. In this paper, a brief review of the importance of
