Enhanced FMEA Methodology for Evaluating Mobile Learning Platforms Using Grey Relational Analysis and Fuzzy AHP

This study addresses a significant problem: it is difficult to choose a suitable mobile learning platform effectively since many learning platforms are readily available for users. For this purpose, the study proposes an efficient way to rank and choose the most suitable mobile learning platform by integrating risk analysis and multi-criteria decision-making methods. The selection of a suitable mobile learning platform is challenging due to the vast collection of available platforms. Traditional decision-making approaches often struggle to manage the inherent uncertainty and subjectivity in platform evaluation. To address this, we propose an enhanced methodology that combines grey relational analysis (GRA) and fuzzy analytic hierarchy process (FAHP), leveraging their complementary strengths to provide a robust and adaptive solution. The study employs ISO/IEC 9126 software quality standards to locate the most suitable mobile learning platform. FMEA is based on three risk factors: occurrence, severity, and detection. The fuzzy analytical hierarchy process (FAHP) is used to determine the relative weight of each risk factor to identify the grey risk priority number that can be calculated for each criterion. Mobile learning platforms are then ranked based on their grey risk priority number. The method was applied to five widely used mobile learning platforms with three decision-makers. In addition, the multi-criteria decision-making software was developed to aid users, educators, and administrators in their decision-making processes. The integrated FMEA-GRA-FAHP technique, using ISO/IEC 9126 standards, provides an effective way of locating the most suitable mobile learning platform and ranking them according to their reliability. This research is believed to be the only study applying an integrated FMEA-GRA-FAHP approach to evaluate the risks and quality of mobile learning platforms. The unique approach overcomes certain limitations of the standalone methods such as FMEA and FAHP, making it a valuable tool for identifying the suitability of mobile learning platforms. In addition, the study underscores the importance of inclusivity and equity in ensuring high-quality education and creating an environment conducive to lifelong learning for all.

Risk management of radioiodine treatment in differentiated thyroid cancer

IntroductionPatient safety is paramount in providing quality healthcare and constitutes a global concern for healthcare systems. Radioiodine treatment to patients with well-differentiated thyroid cancer is not without risks. The aim of this study is to identify, evaluate and mitigate the risks associated with this procedure. Materials and methodsA single-centre descriptive study was conducted in which risk management was carried out by establishing a risk map using FMEA methodology. ResultsBased on the process map 6 sub-processes and 23 failure modes in the three phases of the treatment process were analysed. According to risk priority number (RPN), the sub-process with the highest risk was administrative management (RPN 82), followed by treatment per se and post-treatment imaging (both with RPN 70). An overall process RPN of 300 (156 pre-treatment, 74 treatment and 70 post-treatment) was obtained. Failures directly related to the patient pose a high risk. The implementation of verification systems, performing tasks earlier and providing quality medical information are the most relevant preventive measures to be implemented. ConclusionsThe application of the FMEA methodology in the risk management for radioiodine treatment is a valuable tool for improving the quality and safety of this process. The risk map has been able to identify failures at different stages, assess their causes and effects, prioritise the risks identified and implement preventive and corrective measures that can be monitored, ensuring the effectiveness of the actions taken.

Multifaceted decision support analysis of risk assessment in the process of transporting feed by rail transport using the FMEA method

The article presents selected aspects regarding transporting goods intended for animal feeding. The transport of this type of cargo must meet trade safety requirements and be monitored at every stage of the transport chain. The safety of transport of this type of goods is given priority because possible contamination of feed could affect the quality of food products and threaten human health. The authors referred to the reasons for creating an international procedure regarding, among others, the transport of this group of goods, limiting the risks mentioned above. The proposed procedure is a response to various incidents of feed contamination. It was introduced as an internal system and then developed internationally. The article points to the multi-threaded nature of topics related to the risk management process during the transport of feed intended for animal feeding by rail. This article presents an approach to this issue that considers a multi-aspect analysis of decision support. Risk assessment in transporting feed by rail is an essential factor influencing safety in trade. The article presents the FMEA method, which enables decision support analysis considering non-compliance risk. The recommended method that enables the examination of transport processes for this group of goods is the analysis of the types and effects of possible errors. The task solved using the FMEA method is fed by historical data, the transport task, and the FMEA methodology. Three elements are analyzed - the significance of non-compliance, the risk of non-compliance, and the possibility of detecting non-compliance. They enable quantification and determination of a risk priority number. If the acceptable risk level is exceeded, changes are made to the transport task. The article broadly refers to aspects of risk analysis, which allows you to manage the transport process.

Analisis Potensi Bahaya Dengan Metode Hazard Identification and Risk Assesment dan Failure Mode Effect Analysis Pada PT.XYZ

PT. XYZ is a manufacturing company that specializes in making food and soft drinks. According to the company, there have been no reports of incidents during the production process. However, based on empirical findings obtained from observations in the maintenance section, especially in the field of assembly work, many near misses or near misses occur during the implementation stage. Efforts that need to be made to overcome this are by identifying activities that are at risk of causing work accidents. In this research, work accidents were identified using the HIRA method, which then based on the results of the HIRA, improvements were then carried out based on priorities using the FMEA methodology. In the grinding machine assembly process, it is known that there are six work activities including material selection, grinding, welding, painting, assembly, and machine trial. The HIRA identification results show that there are 8 activities that have a medium risk of work accidents, for which FMEA analysis will be carried out. The results of the FMEA analysis show that the motor selection activity for the grinding drive has the highest RPN value so the control in the work is carried out using the help of a chain block, ensuring the chain block is in prime condition, using complete personal protective equipment, carrying out work according to SOP, and using chain block according to capacity.

Logistics and maintenance research activities for DONES facility

DONES is planned to operate on a continuous basis with only two beam stop periods per year for maintenance. The planned operational availability is 70 %, which calls for a carefully analyzed preventive maintenance. The purpose of the research is to propose a realistic and comprehensive logistics and maintenance plan. All the maintenance activities are included in a Maintenance Matrix based on the Plant Breakdown Structure of the project. This is the basis for the creation of a maintenance plan that will lead to a Work Schedule. Special mention within this matrix will be given to those Maintenance operations that must be included in order to comply with regulation. The need of replacement of components impose some requirements on the dimensions of architectural features of the main building such as doors, airlocks, corridors and shipping bays. To enable these replacements, the flow of materials has been developed and analyzed by an intralogistics simulation with AnyLogic. The results of this simulation lead to modifications on either the building or the components such that the replacements are feasible. The periodic replacement of an activated component has been analyzed using FMEA methodology resulting in proposals for the plant equipment designers as well as the remote handling equipment designers. Virtual reality simulations are used for a staged approach to the maintenance operation. The simulation of the HEBT scraper helped to define in detail each step or the maintenance operation. This tool has proven to be very useful to prompt changes in both the plant equipment design and the remote handling equipment. Also, the procedure of the operation itself can be refined and optimized. The conclusion of the research activities is the contribution to the definition of the building, plant equipment and achievement of the target availability.

Approvisionnement pharmaceutique au centre hospitalier territorial de Nouvelle-Calédonie : état des lieux, évaluation et perspectives

The supply circuit for health products in New Caledonia has characteristics and specificities linked to its geographical situation (extended delivery time, freight forwarder) and its local policy (own currency, fundings, legislation and custom fees). A risk management approach should provide an upgrade of the supply process safety. A system overview is carried out thanks to the processes description (operational and cross-functional). A risk map associated with the FMEA methodology (Failure Mode Effects Analysis) identifies the most critic modes of failure, for which safety action must be taken. A specific rating is introduced when the mode of failure concerns sensitive health products. The mapping identified 32 modes of failure which may affect the clinical management of the patients. Concerning sensitive health products, 11 modes of failure were deemed "to be monitored". None of the failure modes were considered as "to treat as a priority". The security process is ensured by the logistics and accounting unit, internal to the pharmacy structure. Securisation might include deployment of a data exchange system, sensitive health products identification or collaboration with neighbouring countries to import health products. Supply chain reinforcement mesures can be implemented by the public authorities, but should also be sought through territorial collaboration or via the PharmApprOM community of practice bringing together pharmacists in French overseas regions.

Risk identification methodology regarding the safety and quality of railway services

Abstract The paper deals with the implementation of a modified FMEA methodology according to the EU Commission Regulation no. 402/13 on a common safety method for risk assessment and evaluation in the railway sector. The basic goal is to create a methodology for risk identification regarding the safety of services in railway transport concerning railway crossings. Reason for this research was the fact that the manager of the railway infrastructure in Slovakia has problems related to accidents at railway crossings including problems with the quality of services when trains are delayed. Based on previous research, this area has been defined as a priority for risk identification. Accidents at level crossings are often the result of complex interactions between several factors. The results of the authors’ long-term research bring direct impact on the safety and quality of rail transport services. The first effect of the research is a detailed investigation of the causes of accidents, on which the new methodology is based. This is important because understanding the causes of accidents is the first step in eliminating them. The proposed new framework of the methodology provides guidance to the railway infrastructure manager on how to identify, analyze, evaluate and eliminate the risks of their effects.

Assessment and Prioritize Risk Factors of Financial Measurement of Management Control System for Production Companies Using a Hybrid Z-SWARA and Z-WASPAS with FMEA Method: A Meta-Analysis

The management control system in an industry is managerial, directional, hindrance, and cohesive action in order to cohere and regulate various branches and sub-branches. In fact, it is a system that supports the real state of matters in the right way. This method is intended at assuring that the purposes and activities carried out have the desired outcomes and eventually lead to the objects and purposes of the company. In this matter, the financial and non-financial management control system is essential both when it comes to strategy community; Consequently, in this paper, the management control system is classified into financial and non-financial categories because such analysis gives a chance to get a broad assessment of a management control system relationship in organizations. In this paper, we evaluate the relationship between business strategy and management control system and their influences on financial performance measurement of a manufacturer (a case study of Maral Co.) with the use of Merchant’s theory. Furthermore, In this case, a decision-making strategy centered on the FMEA is used to identify and prioritize risk factors financial of the control system in companies. Nevertheless, because this strategy has some significant limitations, this research has presented a decision-making approach depending on Z-number theory. For tackle, some of the RPN score’s drawbacks, the suggested decision-making methodology combines the Z-SWARA and Z-WASPAS techniques with the FMEA method. The findings reveal that in the non-financial management control system element, customer satisfaction, and in the financial component, cost standards are at the largest level of weight. Furthermore, the strategic planning factor with a rate of 2.95 and the deviation analysis factor with a rate of 2.87 is at the lowest level, respectively. In sum, market or industry changes are the primary cause of risk in businesses, according to FMEA methodology and the opinions of three professionals.

Application of RCM and FMEA Methodology to Improve Industrial Maintenance Management: A Case Study of Fibers for Mattresses

In industrial manufacturing, there are techniques that can identify certain risks in the processes that cause inconsistencies in the operation of equipment, hazards for the operator and waste. One of the supports of industrial engineering in the company are the Preventive Maintenance (PM) tasks that focus their efforts on analyzing the operation of critical devices that could degrade the quality of the products obtained. Companies that have an average system of attention to machinery and equipment perform corrective maintenance (CM) or preventive maintenance tasks that are not very successful, due to a deficient knowledge or training in repair, which generates high percentages of waste, low quality, and even reprocessing. Failure mode and effects analysis and reliability-centered maintenance are systematic tools based on team working which usually can be used for identify, prevent, eliminate or control the potential errors causes of failure in a system or process. In this paper, it is intend to reorganize preventive maintenance planning and obtain effective results with all the information and data available specifically on a machine dedicated to the transformation of a raw material to obtain fibers used in mattress filling.

Prediction of cyclic durability and risk analysis of inconsistencies in the supporting structures of mobile vehicles

The reliability and safety of mobile vehicles is determined by their carrier system. Achieving a low probability of failure of structures and reducing the cost of equipment is possible by changing the traditional methods of predicting reliability and applying risk analysis, as well as using risk-based design. The aim of the work is to develop methods for predicting the cyclic durability of elements, fastening prefabricated load-bearing structures and analysis to achieve acceptable risks of mobile vehicles at the stages of risk-oriented design. The methods and standards were developed in order to provide methodological support of risk-based design. Those allow designers and engineers to use new methods of design and calculation of tractor and agricultural machinery. It is proposed to introduce into the existing notation system of design and technological documentation the identifiers for parameters as the priority indicators and to achieve when designing the probability of occurrence of each potential cause of failure up to a given level of risk, taking into account priority. The tool for achieving low failure probabilities is the construction of diagrams of cause-and-effect relationships of failures is the source of cause and effect based on the method of deduction and induction. A calculation and experimental method for predicting reliability, according to the criterion of cyclic durability of load-bearing structures and fasteners was developed. The technique is based on local modeling of damage initiation zones, taking into account the influence of design and technological factors of production, simulating the load mode of a mobile vehicle, its damage zones. The following are used for the calculation: finite element method, experimental load assessment, fatigue resistance characteristics of load-bearing elements, rivets and bolts, damage accumulation hypotheses. Risk analysis is carried out using the FMEA methodology. As a result of the risk analysis in a probabilistic formulation, a conclusion is made about the possible damage to the supplier the number of mobile vehicles that will not ensure the fulfillment of the stated requirements for a given resource and warranty mileage. Thus, data for assessing risks and making a decision on the advisability of redesigning equipment appear. The created methodological support for predicting cyclic durability and risk analysis for the implementation of risk-based design allows: to eliminate the uncompetitive level of product quality and production quality, as well as low efficiency and labor productivity; apply new design technologies, design and production preparation methods that reduce development time. The developed methods and means of the risk-based approach have been widely tested and are used in the practice of auto-tractor-agricultural machine building.

Ultimately, the sensitivity analyses demonstrate that the offered framework is verified and can make applicable data in risk management decision-making evaluation.

Fuzzy Logic Based Approach for Analysis and Synthesis of Failure Modes

Failure analysis and management has been gaining a lot of importance for the last few years. Failure mode and effect analysis is the process used for failure analysis and risk management in judging various businesses and managements. The FMEA is the methodology extensively used in different sectors to detect, prioritize and investigate the potential failures which occur during the production or design of the product. This whole process is computed with the Risk Priority Number (RPN). The blurriness and uncertainty in the FMEA associated with the human expertise and experience is responded using Fuzzy Logic based approach. In today’s time, organizations mainly focus on improving the quality of their product and building the reputation of their organizations. So, they consider every aspect of failure which can occur during the production. So, they use the FMEA team to overcome these issues before their existence. This paper is based on the approach of FMEA methodology and Fuzzy logic which describes multiple risks, insecurities associated with the different production processes and gives the solution to overcome the possible failures. FMEA is a methodology which suggests that such type of failures could occur during the design of the product or the production of the product.

Proactive Risk Assessment through FMEA of Home Parenteral Nutrition Care Processes: A Survey Analysis.

Home Parenteral Nutrition (HPN) is a lifesaving clinical care process. However, undetected hazards and vulnerabilities in care transitions from hospital to community care may pose risk to patient's safety. Avoidable complications and adverse events may hinder the benefits of treatment. The analysis carried out aims at framing through Human Factors and Ergonomics (HF/E) the critical issues for patient safety related to clinical care practices for HPN in healthcare organization. We present the results of a proactive risk assessment analysis based on the FMEA methodology (Failure Mode and Effects Analysis) carried out in three different areas of the regional health care system of Tuscany, Italy. The clinical risk management and patient safety unit assessed the risk perception of Healthcare Workers (HWs) in regard to patient safety and situational awareness throughout the HPN patient journey. The analysis revealed heterogeneity in the Risk Priority Index (RPI) expressed by HWs. A lower RPI is associated with a HPN process that deploys in continuity between hospital care and community care. A higher RPI is associated with a quality and safety improvement process that is still ongoing. We also observed HWs expressing low RPI in the areas of the region where HPN has a hospital- focused approach and has limited adherence to patient safety requirements. Low RPI for HPN process may relate both to extensively deployed continuity of care and to jeopardized awareness on HPN phases and coordination. The analysis carried out enabled the definition of a common HPN workflow used as reference schema allowing for the definition of a set of recommendations for improving the quality and safety of the care processes. Moreover, the outcome of the proactive risk assessment laid the groundwork for the advancement of the patient safety regional requirements. The analysis had the role of promoting the contextualization of the culture of quality and safety within the HPN process resulting in an improved awareness of the criticalities and the role of nutrition units throughout the care process.

Maintenance system of semi-trailer and risk priority number

The new maintenance system of semi-trailer combination as a most used road freight transport means is the subject of interest in this article. The real experiences from practice and creation of the FMEA analysis of the system using software support are the basis of wear and damage analysis of air brake system components used on the semi-trailer combination. The desire to improve market position of the company, customer satisfaction, but also the product specifications, government regulatory requirements, agency recommendations, and legal implications are the grounds for continuous improvement of the product quality, reliability and safety. These reasons push the product manufacturers to perform risk analyses, which helps them identify and minimize system failures during the life cycle of product. One of the risk analysis techniques recommended by international standards to identify possible failure causes is the FMEA methodology. It helps to locate the failures and reduce their consequences, so that the intended function of the machine is fulfilled. In this paper was presented the wear and damage analysis of individual components of air brake system and creating of the FMECA analysis for semi-trailer combination. Base on them, new methods to detect failures of components of air systems, preventive measures and set up of a new planned preventive maintenance system for air brakes was designed. The cost of the proposed maintenance system is 2.2 times higher than the cost of the current maintenance system, but it minimizes the failures and their consequences (traffic accidents).
