The quality of midsole products significantly impacts the quality, durability, and comfort users shoe manufactured by ABC company. high percentage average number product defects based on yield data for 12 months is 3.1% which exceeds required company 2%. There are six types in midsole: yellowing, porous, bubbles, broken, over left material trimming. Three from focus improvement Pareto concept, ...

Failure analysis on the fishing vessel's main engine is one of works that must be completed because it crucial for operation ship. Analysis determining cause and effect failure fuel system goal this study. FMEA (Failure Mode Effect Analysis) a method used to determine priority components in failure. The use Pareto diagrams an additional analysis. RCFA (Root Cause analyze root system. results ob...

Introduction: The Failure Mode and Effects Analysis (FMEA), first of all, identifies dangerous modes in a process and, then, provides proper control measures that are required to reduce the level of risk. This study aims to investigate the risk level before and after the implementation of control measures in an edible oil factory. Methods: This cross-sectional study was conducted in an edibl...

greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...

Background and Aim : Emergency ward is among hospital areas with high risk of errors, thus, implementing measures to identify and correct the errors is essential. The object of this study is to identify and assess the errors of the process of admitting patients in Emergency Department of Imam Reza Hospital using Failure Mode Effects Analysis, as one of the tools to assess and manage risk, as we...

Maintenance of the main engine lubrication system determines engine’s performance and components based on standard Japan Institute Plant Maintenance. The purpose analysis is to determine critical evaluate every component as a base maintenance planning preventive measure avoid downtime during ship operations. Data needed are ship’s motion, damage frequency, components’ downtime, diagram. was ana...

Fault Tree Analysis (FTA) has become a popular tool for use in the Space Industry for the System Safety Engineer. The fault tree is used for everything from tracking hazard reports to investigating accidents, as well as presentations to management. Yet, experience in the space industry has shown the fault tree is used most often for purposes other than its original intent, namely for evaluating...

The paper deals with a quantitative approach to safety assessment process applicable to the safety-related system, specially the railway interlocking one. The authors present the methodology based on the Failure Mode and Effects Analysis (FMEA) and the Fault Tree Analysis (FTA) that is applicable to performing safety analysis of both electronic and computer based systems. The mathematical basis...

Increasingly complex systems lead to an interweaving of security, safety, availability and reliability concerns. Most dependability analysis techniques do not include security aspects. In order to include security, a holistic risk model for systems is needed. In our novel approach, the basic failure cause, failure mode and failure effect model known from FMEA is used as a template for a vulnera...
