Robust parameter design is to identify appropriate settings of control factors that make the system's performance robust to changes in the noise factors that represent the source of variation. In this paper, we introduce a factor analysis approach to simultaneously optimize multiple quality characteristics in the robust parameter design. An example is illustrated to compare it with already proposed method.

Taguchi robust design is widely used to quality improve methods. Especially, interest of dynamic characteristics parameter design is getting grow. In this paper, we have a comparative analyzed three Signal-to-Noise Ratios which are used in American Supplier Institute(ASI), MINITAB and Taguchi series published by Japanese Standard Institute with numerical examples.

The purpose of this study was to examine the consumer's quality evaluation on the apparel of adult males and females. A demonstrative study was conducted using a questionnaire on adults over 20 years old who were considered to afford to purchase clothes. A total of 380 questionnaires were used for the demonstrative analysis. The study used SPSSWIN V.8.0 for the analysis. Frequency analysis, ANOVA, t-test, multiple regression analysis, and duncan test are executed. The study result is as follows: First, 19 attributes of customer quality perception are grouped into 2 categories of satisfier, dissatisfier factor by the role of each attribute. Second, significant differences are found partly in quality indications- including fabric compositions, sizes, fabric care, manufactured-place, and the place of origin, the importance degree of indication and general satisfaction in quality indicating system.

Internet shoppers interact with Internet shopping mall systems while they shop. To understand why Internet shoppers make purchase, this study view Internet shopping malls as information systems. Although this view point seems reasonable, little previous studies employing this perspective are found in the relevant literature. This study develops a research model where Internet shoppers' transaction intentions are affected by the mediating effects of trust and satisfaction. Trust can mitigate uncertainty of the e-commerce environment for consumers, and satisfaction is widely used to measure the effectiveness of information systems. Therefore, we consider them as key elements in this study. We further employ the construct of website quality to explain why shoppers have different levels of trust and satisfaction. We classify website quality into information quality, system quality. and design quality. We collected 282 survey responses from Internet shoppers who have prior experiences with Internet shopping malls to purchase a product or service. The survey data are used to empirically test the proposed nine research hypotheses using LISREL. The LISREL results indicate that information quality and design quality have significant impact on both satisfaction and trust, while system quality has little relation to trust level. Further, trust is shown to have significant influence on satisfaction. Finally. both trust and satisfaction is strongly related to the future transaction intention.

The quality of indoor air quality is facing a very serious situation due to the impact of the quality of the atmosphere in the atmosphere and the surrounding environment. While awareness of the danger of these populations is increasing, there is no way to detect the quality of the indoor air quality as well as the measures to detect the quality of indoor air quality as well as the countermeasures. The study drew a general problem with the design of the service design, the general purpose of the general office, and the use of the public facilities for the purpose of measuring the usage of indoor air quality, the general purpose of public facilities, and the interpretation of the current law. Based on this research, most of the general users' perception of the seriousness of the disease is not reflected in the perception that the dust and indoor air are accumulated in the eyes of the general public.

Purpose: The main purpose of this paper is to assess a body of research evidence that articulates the impact of environment-related factors on behavioral health and quality of life for people with dementia who reside in long-term care facilities. The study also aims at identifying design implications that can be incorporated into design process and design decisions to improve behavioral health and quality of life for people with dementia. Methods: Comprehensive literature review has been conducted to identify empirical studies and that link the design of dementia care facilities to health- and QOL-related outcomes and scrutinized peer-reviewed articles published in many different fields including architecture, psychology, to nursing. Results: The review identified a growing body of literature that articulates environment-related factors that improve health and quality of life for people with dementia living long-term care facilities Implications: The findings of the review can be translated to design decisions to promote psychological and behavioral health and quality of life of people with dementia in long-term care facilities.

This paper presents an analytic method of quality function deployment(QFD) that is to maximize customer satisfaction subject to technical and economic sides in process design. We have used Wasserman's normalization method and the analytical hierarchy process(AHP) to determine the intensity of the relationship between customer requirements and process design attributes. This paper also shows cost-quality model the tradeoff between quality and cost as a linear programming(LP) with new constraints that have designated special process required allocating firstly The cost-quality function deployment of piston ring is presented to illustrate the feasibility of such techniques.

In spite of the emphasis on quality control in auto-industry, most of subcontract enterprises still lack a systematic in-process quality monitoring system for predicting the product/part quality for their customers. While their manufacturing processes have been getting automated and computer-controlled ever, there still exist many uncertain parameters and the process controls still rely on empirical works by a few skilled operators and quality experts. In this paper, a real-time product quality monitoring system for auto-manufacturing industry is presented to provide the systematic method of predicting product qualities from real-time production data. The proposed framework consists of a product quality ontology model for complex manufacturing supply chain environments, and a real-time quality prediction tool using support vector machine algorithm that enables the quality monitoring system to classify the product quality patterns from the in-process production data. A door trim production example is illustrated to verify the proposed quality prediction model.

This study shows a way to develop ergonomic design of a plier through quality function deployment (QFD) approach. User needs for pliers, as well as the engineering characteristics which have influence on the ergonomic quality of pliers were determined from the interviews and questionnaires with various user groups. This information was entered in the house of quality, and the results show that the handle is the most important quality factor. A new model was proposed in which ergonomic and gender aspects were considered. QFD is considered a suitable method especially for the manufacturing and/or design fields where biomechanical or physiological background is not present.
