The metro door system is one of the high failure rate subsystems of metro trains. The Failure Mode, Effects and Criticality Analysis (FMECA) method is applied to analyze the reliability of metro door system in this paper. Firstly, failure components of the door are statistically analyzed, and the major failure components are determined. Secondly, failures are classified according to their impac...

Sistem perawatan yang dilakukan selama ini adalah bersifat breakdown maintenance yaitu pemeliharaan setelah mesin mengalami kerusakan. belum memberikan data akurat kapan suatu atau komponen kerusakan, sehingga strategi tepat untuk menjaga tetap beroperasi menentukan interval waktu optimal.Hasil analisis dengan menggunakan metode Failure Mode Effect Analysis (FMEA) maka didapat kritis pada Mesin...

Palm oil is a plantation crop of high economic value and one the crops producing vegetable various other derivative products. processing factors that determine business productivity palm mill. The smoothness production process greatly influenced by reliability machines used. Ripple Mill machine meisn serves as seed breaker to separate shell from kernel. This study aims identify failures occur i...

Semi-solid materials undergo strain localization and shear band formation as a result of granular nature of semi-solid deformation. In the present study, to analyze the shear localization, a unified viscoplastic constitutive model was developed for the homogeneous flow. Then, a linearized analysis of the stability performed by examining the necessary condition for the perturbation growth. For t...

Actual load, material characteristics and other quantities often differ from the design values. This can cause worse function, shorter life or failure of a civil engineering structure, a machine, vehicle or another appliance. The paper shows main causes of the uncertainties and deviations and presents a systematic approach and efficient tools for their elimination or mitigation of consequences....

Evaluation and improvement of drug management process are essential for patient safety. The present study was performed whit the aim of assessing risk of drug management process in Women Surgery Department of QEH using HFMEA method in 2013. A mixed method was used to analyze failure modes and their effects with HFMEA. To classify failure modes; nursing errors in clinical management model, for c...

Background A multidisciplinary working group applied the Healthcare Failure Mode and Effects Analysis (HFMEA) approach to the flow of kits and specimens for the first-level test of a colorectal cancer screening programme using immunochemical faecal occult blood tests. Methods HFMEA comprised four steps: (1) identification and mapping of the process steps (subprocesses); (2) analysis of failur...
