Using Fuzzy Cost‐Based FMEA,GRA and Profitability Theory for Minimizing Failures at a Healthcare Diagnosis Service

This paper proposes an integrated approach to identify, evaluate and improve the potential failures in a service setting. This integrated approach combines Fuzzy cost‐based service‐specific FMEA (FCS‐FMEA), Grey Relational Analysis (GRA) and profitability theory for better prioritization of the service failures by considering cost as an important issue and using the profitability theory in a way that the corrective actions costs are taken into account. Considering profitability with FCS‐FMEA and GRA reduces the losses caused by failure occurrence. Besides, a maximization linear mathematical problem is used to select the best mix of failures to be repaired. We apply our approach to an academic example concerning the potential failures diagnosis of the Internal Medicine service of a hospital located in Seoul, Korea. We applied our approach and solved the associated maximization problem by a commercial solver, producing an optimal solution which indicates the most convenient mix of failures to be repaired by considering available budget.

功能安全技术讲座——第二十四讲 FMEA工作原则及基础工作的重要性

FMEA作为功能安全工作的一个重要组成部分,不仅能从定性的角度上分析产品是否满足功能安全要求,同时还从为各类失效率计算（PFH/PFD）和安全完整性等级判定（SIL）提供有效数据支撑,但是当前FMEA工作中存在诸多问题,导致其丧失了在功能安全中应有的价值和意义,本文从分析FMEA工作的普遍现状着手,以实现FMEA价值为分析导向,确定了FMEA的工作原则,最后详细论述了FMEA基础工作的内容及其必要性。     

System fault-tolerance analysis of COTS-based satellite on-board computers

Fault-tolerance analysis reveals possible system behavior under the influence of faults. Such analysis is essential for satellites where faults might be caused by space radiation and autonomous recovery is needed. In this paper we present a statistical simulation approach for fault-tolerance analysis of satellite On-Board Computers (OBCs) that are based on Commercial Off-The-Shelf (COTS) components. Since the logic level of COTS electronics is unknown to satellite designers, a new higher-level fault-tolerance analysis is required. We propose such technique that relies on OBC modeling and fault modeling, based on the modeling principle of Single-Event Upsets (SEUs). For the first time we can compare the efficiency of fault-tolerance techniques implemented in software and Field-Programmable Gate Array (FPGA). In addition, our approach enables to analyze system fault-tolerance at early development stages. In a case study the approach is applied to an OBC with a Microsemi SmartFusion SoC, that executes a satellite attitude control algorithm. The gained statistical simulation results enabled 50% reduction in the hardware overhead of the implemented memory scrubbing technique without loss in fault-tolerance. Our method revealed critical fault-tolerance drawbacks of the initial system design that could have lead to satellite mission failure.     

基于HoR的可靠性配置方法研究

运用HoR(House of Reliability)思想,将故障树分析(FTA)、失效模式影响及危害性分析(FMECA)整合于质量功能配置(QFD)中,建立可靠性配置流程:对系统可靠性指标进行分配,解决了传统方法过度依赖于主观打分的问题;在此基础上,建立以顾客可靠性满意度最大和配置成本最低为目标的模型,将可靠性指标配置到具体的工程技术特征上。并以数控车床电主轴为例,对模型的有效性进行了验证。     

Project finance risk evaluation of the Electric power industry of Serbia

From the aspect of the development of a country, the energy sector represents a domain of strategic interest. Generation and use of energy resources most often belongs to the public sector, and are most often under the influence of the government in most countries. This paper analyzes the risks that are characteristic to the business of the public enterprise, Electric Power Industry of Serbia (EPS). EPS has started its restructuring and is adjusting to changes and challenges imposed by the launched reforms in the energy sector. However, due to certain limitations, it is still not possible to implement its complete restructuring and modernization. The paper aims to point at the risks a potential strategic partner faces. The risks have been identified as commercial, financial and political, classification immanent for project finance, and their evaluation was done using Failure Mode and Effects Analysis (FMEA). Risk analysis was performed based on current conditions for two potential scenarios that predict different types of changes in the analyzed period. The results of the analysis show that the potential strategic partner should pay special attention to price risks, estimation, investments, project activity neglect, quasi-risks and debt collection.     

Business Continuity Management: A Standards-Based Approach

ABSTRACT

Business enterprises are increasingly realizing the importance of business continuity management (BCM). Availability BS 25999 Standard has facilitated a consistent methodology that organizations can follow in designing their BCM System. This paper intends to provide a conceptual understanding of BCM right from BCM Policy to BCM maturity by describing the steps involved in the implementation of BCM Standard – BS 25999 – to ensure business continuity in the event of an outage. The key BCM tasks have been categorized into three phases of business continuity – Pre-event Preparation, Event Management, and Post-event Continuity. This paper also highlights some of the challenges experienced by the author in carrying out Risk Assessment and Business Impact Analysis. The Business Continuity Maturity Model® of Virtual Corporation is provided (with their permission) as a tool to strengthen business continuity maturity or organizations.
