Background and aims : Technique of Failure Modes Effects and Criticality Analysis, FMECA, is a method for identifying and analyzing all potential failure modes of a system.This technique is used to prevent failures and to reduce their effects on the system . The main goal of this study was identifying and analyzing of the potential failure modes and assessing the effects of failures in the ce...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...
The purpose of this research is to demonstrate the importance of extracting business process mappings as a prerequisite for the implementation of the PFMEA (Process Failure Mode and Effect Analysis). In the first stage, 30 production process failures were extracted in the meetings with factory managers. Then, a team was formed by the presence of process owners, and with the help of the project ...
Background and aims Prevention of potential accidents and safety promotion in chemical processes requires systematic safety management in them. The main objective of this study was analysis of important process equipment components failure modes and effects in H2S and CO2 isolation from extracted natural gas process. Methods This study was done in sweetening unit of an Iranian gas refi...
Background: The goal of clinical risk management is to improve the quality of health care organization’s services and to ensure patients' safety. Thus, this study has identified and evaluated the potential failures by Failure Mode and Effects Analysis (FMEA) approach to eliminate errors occurrence of an Intensive Care Unit (ICU) in a hospital in Tehran city. Materials and Methods: This study...
Background: Adverse Events (AEs) due to failure in healthcare procedures are common. These procedures are often evaluated independently. The objectives of this study are to investigate the nature of the failures in healthcare procedures of the surgical patients, assessing the frequency of these failures and preventability, and exploring their consequences, underlying causes, and prevention stra...
Abstract Background and aims: Nowadays with increasing global competition, companies apply several scientific methods to identify, assess and remove potential failures in production process. The main goal of this study was identification and analysis of potential failure modes in a hydraulic pump manufacturing company by using combination of interval valued fuzzy Analytic network process (IVF-...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
