Customer Requirements (customer + requirement)
Selected AbstractsDevelopment of Multiple Power Quality Supply System,IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, Issue 5 2010Keiichi Hirose Member Abstract This paper describes the characteristics and performances of a multiple power quality supply system (MPQSS), which consists of power electronics-based voltage compensators and three types of distributed generators (DGs). Its original concept of a future power delivery system having different service levels to meet each customer or load requirement at the same time was proposed as Flexible, Reliable, and Intelligent Electrical eNergy Delivery System (FRIENDS). The effectiveness of the developed power system was measured during an actual field demonstration conducted in 2007 by the New Energy and Industrial Technology Development Organization (NEDO), Sendai, Japan. Its effectiveness in feeding four classes of alternative current (AC) and one of direct current (DC) power while meeting various customer requirements was confirmed. Some sets of test data and an analysis using the data indicate that the developed system meets all the requirements for DG-related plants and has additional benefits. The power system maintains voltage and frequency conditions without interruption in the every state, grid interconnection, islanding, and backup modes.

[source] Barriers to HACCP implementation: evidence from the food processing sector in Ontario, CanadaAGRIBUSINESS : AN INTERNATIONAL JOURNAL, Issue 2 2010Deepananda Herath This study explores the barriers that impede the adoption of hazard analysis and critical control point (HACCP) by food processing firms in Ontario, Canada. The study identifies four broad groupings of barriers to HACCP implementation, namely perceptions that HACCP is of "questionable appropriateness" to the firm, the scale of change required to achieve implementation, low priority given to enhancement of food safety controls, and financial constraints. The severity of these identified barriers differs significantly between firms that have implemented HACCP and those that have not. In particular, HACCP implementation is impeded significantly by barriers related to financial constraints. The most important driver promoting implementation is customer requirements for HACCP to be implemented in supplier facilities. [EconLit citations: D210, L600, L660]. © 2010 Wiley Periodicals, Inc. [source] Technical decomposition approach of critical to quality characteristics for Product Design for Six SigmaQUALITY AND RELIABILITY ENGINEERING INTERNATIONAL, Issue 4 2010Yihai He Abstract Product Design for Six Sigma (DFSS) approach is a structural and disciplined methodology driven by critical to quality characteristics (CTQs). How to identify and decompose the CTQs is the kernel part in the DFSS process. Traditional method only depends on the quality function deployment (QFD) matrix to flow down CTQs roughly. The paper puts forward a novel technical approach for CTQs decomposition from customer requirements into critical technical parameters based on the relational tree. Specifically, this approach emphasizes the systematic process and quantitative computation on quality relation weight. In order to specify the object of product DFSS, the connotation and evolution model of CTQs are created first. Then along the product development process, a decomposition measure for relational tree of CTQs is studied based on the functional and physical trees in Axiomatic Design (AD). And the quality relation weight computation of its nodes by means of Rough Set and fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is explored. Finally, an application on a car body noise vibration harshness (NVH) improvement, as an example, is given, and the decomposition process of NVH related with the functional and physical trees as well as its node weights computation algorithm are expounded in detail.

Aldridge Abstract Component thermal response is dependent upon numerous factors including the atmospheric temperature, heat sinks and sources, vehicle use time, etc. The number of significant thermal cycles and time at temperature for many components will be related to the number of times the engine is started. This paper provides a methodology to determine the number of significant thermal cycles and time at temperature a product will experience in 10 years which will depend upon engine starts. These calculations provide the basis for an accelerated test requirement to qualify the product based upon customer usage measurements. Because of the trace ability and linkage, the methodology is more marketable to internal and external customers, and less likely to be questioned or arbitrarily overruled. It also enables relative severity assessments for historical customer requirements compared with field needs. Copyright © 2004 John Wiley & Sons, Ltd. [source] The Needs and Benefits of Applying Textual Data Mining within the Product Development ProcessQUALITY AND RELIABILITY ENGINEERING INTERNATIONAL, Issue 1 2004Rakesh Menon Abstract As a result of the growing competition in recent years, new trends such as increased product complexity, changing customer requirements and shortening development time have emerged within the product development process (PDP). These trends have added more challenges to the already-difficult task of quality and reliability prediction and improvement. They have given rise to an increase in the number of unexpected events in the PDP. Traditional tools are only partially adequate to cover these unexpected events. As such, new tools are being sought to complement traditional ones. This paper investigates the use of one such tool, textual data mining for the purpose of quality and reliability improvement. The motivation for this paper stems from the need to handle ,loosely structured textual data' within the product development process. Thus far, most of the studies on data mining within the PDP have focused on numerical databases. In this paper, the need for the study of textual databases is established. Possible areas within a generic PDP for consumer and professional products, where textual data mining could be employed are highlighted. In addition, successful implementations of textual data mining within two large multi-national companies are presented. Copyright © 2003 John Wiley & Sons, Ltd. [source] Management tools for the evaluation of compliance and costs in the production of chemical,pharmaceutical companiesQUALITY ASSURANCE JOURNAL, Issue 3 2005Franziska Rank Abstract Due to the stringent and increasingly demanding Good Manufacturing Practice (GMP) and customer requirements, companies within the chemical,pharmaceutical sector share the enormous challenge of evaluating and measuring compliance and costs. The need for implementing a compliance measuring tool for production was identified within the Schering AG and activities were undertaken. The established compliance evaluation system and the first model for a compliance cost system proved to be well-structured and suitable for the production. Consequently, the systems can be adapted by other areas and chemical,pharmaceutical companies and may even be expanded to other areas, such as Good Laboratory Practice (GLP) and Good Clinical Practice (GCP).

Ivory Two case studies of capital goods projects, both of which were faced with new forms of demand for their products, are reported in this paper. In both cases, the contracting organisations involved were adjusting to new customer requirements for the long-term provision of the services associated with the capital goods they normally produced, rather than for the capital goods themselves. While both contracting organisations recognised the need to re-focus their equipment design efforts, to reflect the need for long-term service reliability (both contracting organisations were tied to penalties associated with agreed service levels), they nevertheless responded differently to this challenge, and their differing responses reflected the differing natures of the extended networks which comprised both projects and the organisational architectures in which the projects were themselves embedded. The paper explores the differing opportunities and barriers to the management of design in complex projects presented by these two case studies. In so doing it points to the conclusion that successful design management in complex projects can depend upon the successful management of the (multiple) contexts in which design takes place. [source] Customer-Driven Product Development Through Quality Function Deployment in the U.S. and JapanTHE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 4 2000John J. Cristiano Quality Function Deployment is a tool for bringing the voice of the customer into the product development process from conceptual design through to manufacturing. It begins with a matrix that links customer desires to product engineering requirements, along with competitive benchmarking information, and further matrices can be used to ultimately link this to design of the manufacturing system. Unlike other methods originally developed in the U.S. and transferred to Japan, the QFD methodology was born out of Total Quality Control (TQC) activities in Japan during the 1960s and has been transferred to companies in the U.S. This article reports on the results of a 1995 survey of more than 400 companies in the U.S. and Japan using QFD. The research questions investigated in this study were developed both inductively from QFD case studies in the U.S. and Japan and deductively from the literature. The reported results are in part counterintuitive. The U.S. companies reported a higher degree of usage, management support, cross-functional involvement, use of QFD driven data sources, and perceived benefits from using QFD. For the most part, the main uses of QFD in the U.S. were restricted to the first matrix ("House of Quality") that links customer requirements to product engineering requirements and rarely was this carried forward to later matrices. U.S. companies were more apt to use newly collected customer data sources (e.g., focus groups) and methods for analyzing customer requirements. Japanese companies reported using existing product data (e.g., warranty) and a broader set of matrices to a greater extent. The use of analytical techniques in conjunction with QFD (e.g., simulation, design of experiments, regression, mathematical target setting, and analytic hierarchy process) was not wide spread in either country. U.S. companies were more likely to report benefits of QFD in improving cross-functional integration and better decision-making processes compared to Japanese companies. Possible reasons for these cross-national differences as well as their implications are discussed. [source] Product selection in Internet business: a fuzzy approachINTERNATIONAL TRANSACTIONS IN OPERATIONAL RESEARCH, Issue 3 2010B. K. Mohanty Abstract In this paper, we propose a methodology which helps customers buy products through the Internet. This procedure takes into account the customer's level of desire in the product attributes, which are normally fuzzy, or in linguistically defined terms. The concept of fuzzy number will be used to measure the degree of similarities of the available products to that of the customer's requirements. The degrees of similarities so obtained over all the attributes give rise to the fuzzy probabilities and hence the fuzzy expected values of availing a product on the Internet as per the customer's requirement. Attribute-wise the fuzzy expected values are compared with those of the available products on the Internet and the product that is closest to the customer's preference is selected as the best product. The multi-attribute weighted average method is used here to evaluate and hence to select the best product. [source] Business process semi-automation based on business model managementINTELLIGENT SYSTEMS IN ACCOUNTING, FINANCE & MANAGEMENT, Issue 4 2002Koichi Terai It is important to respond to customers' requirements more rapidly than ever before due to the recent trend in e -business and its technologies. In order to achieve an agile response, we have to manage business models, to re,ect the changes in the models and to develop or modify IT systems for further chances. This paper proposes a management framework of layered enterprise models. The proposed framework consists of a business model repository and a software repository, and de,nes three different grain sizes of modeling layers, namely business modeling, business process modeling and business application modeling, in order to support business modeling and application development. This framework helps us to develop business application in incremental deployment of analysis, design, and implementation to execute business processes. We have implemented a prototype environment using Java. Each repository's contents are described using XML so that the repositories are interoperable. Copyright © 2003 John Wiley & Sons, Ltd.
