Structured Approach

Design recovery is defined as determining the relevant form and functions and their relationships for a component in order to generate a complete engineering representation. To lead to a more complete model, an integrated approach that assesses the component from different perspectives is presented here, as no one perspective or set of tools can provide a comprehensive engineering representation. There is always the potential for error; hence, the necessity to assess latent design and/or design recovery issues in rigorous manner. A modified failure modes and effects analysis (FMEA) was developed to provide a foundation for the reconstructed model’s design validation. The modified FMEA is designed to interface directly with the design recovery framework. A matrix based procedure, which considers feature functions and relationships, is developed to assist the designer to quickly assess the feature design using a consistent structured approach. The results are plotted, and subsequent testing strategies are suggested based on the characteristics of the features being assessed. Examples illustrate the proposed methodologies and highlight their merits.

Purpose The purpose of this paper is to introduce an integrated approach using failure modes and effects analysis (FMEA), multiple-criteria decision making (MCDM), mathematical modeling and quality function deployment (QFD) techniques, for risk assessment and service quality enhancement in coronary artery bypass grafting (CABG) as a treatment for cardiovascular diseases (CVDs). Design/methodology/approach First, the disruptions in the CABG process are identified and prioritized following FMEA instructions, using two MCDM techniques, called analytic hierarchy process (AHP) and TOPSIS. Consequently, several corrective activities are identified and weighted on the basis of QFD. Finally, a mathematical model is established to determine the most cost-effective activities for implementation. The approach is developed in a fuzzy environment to reflect the uncertainty and ambiguity of human reasoning. Findings Regarding the CABG process disruption, a total of 30 failure modes in four main categories were identified and prioritized. Moreover, eight corrective activities were devised and ranked according to their impact on the failure modes. Finally, considering a limited amount of budget, a sensitivity analysis on the mathematical model’s objective function indicated that using 30 percent of the total budget, required to implement all corrective activities, was enough to cover more than 70 percent of the effects of corrective activities on the failure modes. Originality/value This paper contributes to the quality risk assessment knowledge by introducing an integrated approach to evaluate and improve healthcare services quality. Also, the case study conducted on the CABG process has not been done by other related studies in the literature.

PurposeThis paper aims to develop a system dynamics (SD) model to identify causal relationships among the elements of failure modes and effects analysis (FMEA), i.e. failure modes, effects and causes.Design/methodology/approachA causal loop diagram (CLD) has been developed based on the results obtained from interdependencies and correlations analysis among the FMEA elements through applying the integrated approach of FMEA-quality function deployment (QFD) developed by Shaker et al. (2019). The proposed model was examined in a steel manufacturing company to identify and model the causes and effects relationships among failure modes, effects and causes of a roller-transmission system.FindingsFindings indicated interactions among the most significant failure modes, effects and causes. Moreover, corrective actions defined to eliminate or relieve critical failure causes. Consequently, production costs decreased, and the production rate increased due to eliminated/decreased failure modes.Practical implicationsThe application of CLD illustrates causal relationships among FMEA elements in a more effective way and results in a more precise recognition of the root causes of the potential failure modes and their easy elimination/decrease. Therefore, applying the proposed approach leads to a better analysis of the interactions among FMEA elements, decreased system's failure rate and increased system availability.Originality/valueThe literature review indicated a few studies on the application of SD methodology in the maintenance area, and no study was performed on the causal interactions among FMEA elements through an FMEA-QFD based SD approach. Although the interactions of these elements are significant and helpful in risks ranking, researchers fail to investigate them sufficiently.

Abstract Failure Mode and Effects Analysis (FMEA) is a systematic approach for evaluating the potential failure modes in a system, and is mainly employed in three distinct tasks labelled: (1) Functional FMEA – evaluating those failures associated with product functional definition, (2) Design FMEA – analysing those failures associated with design definition and (3) Process FMEA – assessing potential failures in manufacturing and assembly processes. The literature review has shown limited works on the field of synchronising these different tasks into a working model. To address this gap, this research developed a framework for integrating these tasks of FMEAs, and then qualitatively validating the proposed framework. This research adopted a semi-structured questionnaire to collect experts’ feedback and validate the proposed framework. The t-test was then employed to evaluate the collected feedback. The findings highlight that the proposed framework is applicable and could facilitate the synchronisation of the different tasks of FMEA. This research presents a methodological approach for executing and synchronising FMEAs. Therefore, the proposed framework is practically relevant as an aid for the practitioners in catching the cascading failures and reducing the relevant impact.

Atrial fibrillation (AF) is a complex pathology that requires an integrated approach in both diagnosis and treatment, including optimal prevention of thrombosis, control of clinical symptoms, and identification and treatment of cardiovascular risk factors and comorbidities. The article analyzes some of the new positions of the recommendations of the European Society of Cardiology on atrial fibrillation, presented in 2020. Effective diagnostic and therapeutic approaches are discussed in the management of patients with AF in conditions of multimorbidity. The basic principles of the CC to ABC concept, introduced with the aim of improving a structured approach to the treatment of patients with AF, and the 4S-AF regimen necessary for decision on the use of oral anticoagulants, choosing a method of control of the rhythm and / or its frequency, choosing between ablation, cardioversion and antiarrhythmic drugs, as well as to determine the mode of treatment of major cardiovascular diseases. To improve the prognosis and achieve the best results in these patients, the most important is to reduce the risk of stroke, control cardiovascular risks and comorbidities, and ensure high adherence to the therapy within the framework of the concept of comprehensive patient protection. Rivaroxaban is considered by the authors of the article as one of the drugs that provides comprehensive anticoagulant protection of patients with AF. The efficacy profile of rivaroxaban in the prevention of acute cerebrovascular accident and high safety rates were confirmed in a population of multimorbid AF patients of different ages and the highest risk of stroke and / or bleeding.

Healthcare facilities are facing major issues and challenges. Hospitals continuously search approaches to improve operations quality, optimize performance, and minimize costs. Specifically, an efficient hospital sterilization process (HSP) allows reusable medical devices (RMDs) to be more quickly available for healthcare activities. In this context, this paper describes an integrated approach developed to analyze HSP and to identify the most critical improvement actions. This proposed approach integrates four quality tools and techniques. Firstly, a structured analysis and design technique (SADT) methodology is applied to describe HSP as a hierarchy of activities and functions. Secondly, the failure modes and effects analysis (FMEA) method is used as a risk assessment step to determine which activity processes need careful attention. Thirdly, a cause–effect analysis technique is used as a tool to help identify all the possible improvement actions. Finally, priority improvement actions are proposed using the quality function deployment (QFD) method. To validate the proposed approach, a real sterilization process used at the maternity services of Hedi-Cheker Hospital in the governorate of Sfax, Tunisia, was fully studied. For this specific HSP, the proposed approach results showed that the two most critical activities were (1) improving the coordination between the sterilization service and the surgery block and (2) minimizing the average duration of the sterilization process to ensure the availability of RMDs in time.
