Developing Pandemic Prevention and Control by ANP-QFD Approach: A Case Study on Urban Furniture Design in China Communities.

Background: An infectious disease can affect human beings at an alarming speed in modern society, where Coronavirus Disease 2019 (COVID-19) has led to a worldwide pandemic, posing grave threats to public security and the social economies. However, as one of the closest attachments of urban dwellers, urban furniture hardly contributes to pandemic prevention and control. Methods: Given this critical challenge, this article aims to propose a feasible solution to coping with pandemic situations through urban furniture design, using an integrated method of Quality Function Deployment (QFD) and Analytic Network Process (ANP). Eight communities in China are selected as the research sites, since people working and living in these places have successful experience preventing and containing pandemics. Results: Three user requirements (URs), namely, usability and easy access, sanitation, and health and emotional pleasure, are determined. Meanwhile, seven design requirements (DRs) are identified, including contact reduction, effective disinfection, good appearance, social and cultural symbols, ergonomics, smart system and technology and sustainability. The overall priorities of URs and DRs and their inner dependencies are subsequently determined through the ANP-QFD method, comprising the House of Quality (HQQ). According to the theoretical results, we propose five design strategies for pandemic prevention and control. Conclusion: It is demonstrated that the incorporated method of ANP-QFD has applicability and effectiveness in the conceptual product design process. This article can also provide a new perspective for pandemic prevention and control in densely populated communities in terms of product design and development.

Identification and Evaluation of the Ways of Meeting Patients' Expectations from a Hospital: An AHP-Weighted QFD Case Study In A Pediatric Hospital

The purpose of this study is to determine the expectations of pediatric patients from a hospital and find out feasible solutions to address these expectations. In accordance with this purpose, an AHP-weighted QFD case study was carried out in a pediatric hospital in Turkey. In order to determine the expectations of pediatric patients; face-to-face and semi-structured interviews were used and the natural environment of the hospital was observed in many different times. Expectations of the children constituted the left part of the House of Quality (HoQ) of QFD and were weighted using the AHP. Then, technical requirements offering solutions to expectations of children were defined, other parts of the house were added and the whole HoQ was completed. The results show that, from the children’s point of view, accommodation services was found as the most important factor and arrangement of the patient rooms as the most important sub-factor. All remaining factors and sub-factors were also evaluated and prioritized. It is hoped that this study can contribute to the related literature and the QFD model developed in the study can be taken as an example by similar and/or different hospitals. Finally, the limitations of this study and future research directions are outlined.

Balancing user requirements and implementation difficulties in the requirements engineering of production tools for user-generated content: a case study of an animation application

Some content forms, such as animation, are superior in many aspects but rarely created in UGC systems partially due to the lack of available content-producing tools. Requirements engineering of User-Generated Content project can be difficult because of the diversities of user types, user abilities and client performance resulted from heterogeneous stakeholders. Based on the joint perspective of requirement analysis and quality control, this paper aims to propose an Exploratory Factor Analysis (EFA) integrated Quality Function Deployment (QFD) method. It divides users into expert and regular users, and allows the former to directly participate in design decisions and the latter to participate in prioritization. A case study of the requirements engineering of a Web-based animation application was carried out. The results showed the applicability of the proposed method to develop and manage requirements from all stakeholders. The integration of EFA contributed to the identification of unstated requirements to some extent. Also, the House of Quality was constructed and the quality requirements were obtained during the analysis. This approach helps analysts to sort out the priorities of user and technical requirements and achieve balance between them.

DETERMINING PRIORITY NEEDS OF CULINARY MICRO-ENTERPRISE CUSTOMERS IN INDONESIA THROUGH A QUALITY PERSPECTIVE

Determining the priority of customer needs is one of the right steps for business people to take to determine the direction of allocating their resources. In this study, affinity diagrams and tree charts are used to classify and translate the opinions of loyal customers about customer needs. The customer opinion (voice of the customer) obtained through semistructured interviews is then translated into a technical language (voice of quality) that has a relationship and correlation to existing theories. Data in the form of items of customer need, which are the result of affinity diagram analysis and tree diagrams, are then presented using a matrix that takes the left and right chamber of the House of Quality (HOQ) matrix from the Quality Function Deployment (QFD) method. Matrix that adopts the left and right chamber of HOQ matrix will display the items of customer needs and their priority level. The purpose of this study is to identify the item of customer needs and determine the priority level of customer needs for micro culinary fried rice enterprise in Indonesia. The variable Service Quality in the dimension of Responsiveness with the indicator item Fast Service ranks third.

HoQ-based evaluation of UHC competencies using an extension of interval-valued spherical fuzzy and hesitant 2-tuple linguistic term sets

Healthy life is recognized as one of the most fundamental human rights. However, even today, millions of people around the world are forced to choose between their basic needs and fundamental rights. Half of the world’s population does not have access to the healthcare they need. Universal Health Coverage (UHC) aims to ensure that all individuals receive the quality health services they need without incurring a financial burden, and to protect them from risk factors that threaten their health. The aim of this study is to identify the significant factors to improve UHC in the countries. For this purpose, house of quality (HoQ) approach is used in the analysis process so that both customer expectations and technical requirements are considered. Within this framework, a novel hybrid model has been proposed which has three different stages. Firstly, 3 groups of diseases and 4 clinical services for each group are determined regarding the customer needs. Secondly, these factors are weighted by using interval-valued intuitionistic hesitant 2-tuple fuzzy decision making and trial evaluation laboratory (DEMATEL). In the final stage, 9 different technical requirements are ranked by using interval-valued intuitionistic hesitant 2-tuple fuzzy technique for order preference by similarity to ideal solution (TOPSIS). Additionally, another evaluation has also been conducted by considering Spherical fuzzy sets. Similarly, a comparative analysis has also been performed with VIKOR while ranking the alternatives. It is concluded that analysis results of both evaluations are quite similar. This situation gives an information about the coherency and consistency of the analysis results. The findings indicate that treatment services in noncommunicable diseases play the most significant role in this respect. Moreover, according to the ranking results, it is concluded that strategic policies should be related to improving the social security and special physician capacity as well as decreasing the out-of-pocket payment.

House of Quality-Based Analysis of New Service Development Using Context Free Grammar Evaluation-Enhanced Fuzzy Hybrid Modelling

The purpose of this study is to analyze new service development competencies based on house of quality (HoQ) in the healthcare industry by using a hybrid interval-valued intuitionistic decision-making approach with fuzzy linguistic information modelled by hesitant fuzzy linguistic term sets (HFLTSs) and linguistic 2-tuples. The novelty of the manuscript is to identify a list of criteria, dimensions, and alternatives for HoQ-based new service development used for the investment decisions in healthcare industry. Thus, a hybrid model with HFLTSs has been proposed, considering 2-tuple linguistic information, Interval-Valued Intuitionistic Fuzzy Sets (IVIFSs) and a defuzzification process with an attitudinal expected score function. Hence, a DEMATEL extension dealing with HFLTSs, linguistic 2-tuple and IVIFS has been developed and used to weigh the criteria and dimensions of customer needs. Similarly, a TOPSIS extension dealing with the same type of information is introduced and applied in order to rank the technical requirements, the so- called “new service development competencies in healthcare industry”. Thus, this study contributes to the literature of health economics and management by proposing an original methodology. It is identified that financial expectations play the most significant role for demanders of healthcare services. Hence, competitive pricing strategies should be generated to obtain consumer loyalty in the healthcare industry. Moreover, technological infrastructure is found as the best ranked technical requirement of new service development competencies.

Application of Quality Function Deployment to the Management of Information Physical Security

Information physical security (IPS) refers to the prevention from intended attacks against all material devices and to the protection against deliberate attacks by supporting and managing related data/information. Information in today's world represents an important asset to be protected and for this reason it is necessary to adopt a suitable method for risk and security management. The Quality Function Deployment (QFD) method was originally developed as a tool capable of ensuring a valuable help in the design of products and services, guaranteeing customer satisfaction and value creation. The core of the method is the set of matrices called the ‘House of Quality’ (HoQ), which relates the Customer Requirements (CRs) with Engineering Characteristics (ECs): in other words, the HoQ is a way of translating customer requirements into design parameters. Numerous studies have demonstrated its use in a wide range of sectors. In particular, its application in the security engineering context has been investigated by means of the House of Security (HoS). Its objective is represented by the classification of the components of a security system in response to different scenarios of voluntary attacks. Based on this, the aim of the study consists in extending such an approach to information physical security. More in detail, the purpose of this paper is the development of a systematic model, based on the HoS and applicable to information physical security, that allows the definition and raking of the vital components of an information physical security system (IPSS). In this way, it is possible to perform a proper cost/benefit analysis, considering a general physical layout of a certain organization so that the results can be wide-ranging and applicable in different contexts.
