A Decision-Support Tool for the Choice of Fabrication Routes in the Context of Mass Personalization

In the saturated competitive markets of today, Mass Personalization (MP) is getting more and more attention. MP refers to the affordable fabrication of personalized products where the customer is involved from the beginning of product life-cycle (design phase). In order to keep personalized products affordable, it is important to select the most cost-effective fabrication route for each individualized order. To do so, this study proposes a Web-based Personalized Manufacturing Consulting System (WebPMCS) towards selecting the most cost-effective processes/resources for mass personalization in the on-demand manufacturing context. The proposed tool includes a Graphical User Interface (GUI), a cost estimation model, and a relational database. In this document, we explain the steps towards WebPMCS design and development. Then, we adapt WebPMCS to Spark Assisted Chemical Engraving (SACE). By the aid of this case-study, we validate the tool, and determine the most cost-effective fabrication routes for several personalized orders. Finally, we suggest using multi-head machines for SACE personalized fabrication and prove its benefits using WebPMCS. The proposed tool acts as an advanced calculator and a process/resource selector, and is aimed to be used as an enabling module for industry 4.0 manufacturing philosophy

An analytical surver on customization at modular systems in the context of industrial design

Thesis (Master)--Izmir Institute of Technology, Industrial Design, Izmir, 2006Includes bibliographical references (leaves: 96-99)Text in English; Abstract: Turkish and Englishxi, 99 leavesEnterprises in all branches of industry are being required to become more user focused, yet, at the same time, increasing competitive pressure dictates that costs must also continue to decrease. Mass customization and modularity are strategies developed to address this challenge by producing goods and services meeting individual customer's needs with near mass production efficiency. However, while mass customization and modular systems have already been discussed in the literature, reports on practical implementation of the principles of mass customization in businesses can be found only within the last years. It is a challenge of manufacturing to produce variety of products with limited resources. As corporations strive to rationalize their manufacturing facilities and to produce a large variety of products at lower cost, modularity is becoming a focus of attention. Modular products and reconfigurable processes are crucial to agile manufacturing and provide a way to produce a variety of products that satisfy various customer requirements in time. This modular approach promises the benefits of high volume production (that arises from producing standard modules) and at the same time, the ability to produce a wide variety of products that are customized for individual customers. Such modular product design has been stated as being a goal of good design. Mass Customization target is the transformation of knowledge into "new" products or services, thus customizing and adapting first knowledge then the product itself. Customizing knowledge happens through instantiation and adaptation of design prototypes of the products or the component to fit the individual needs of the customer. This thesis. emphasis is placed on mass customization and modularity which can be seen as key strategies for making firms more customer centric. Furthermore, provide an introduction into principles, concepts, and demarcations, for mass customization and modularity. As the case study Aye Birsel.s resolve model for Herman Miller is a very good example for the relationship between mass customization and modularity

Approach to C2F2C (customer to factory to customer) strategy: a case study of the Fanqing Furniture Company

Hotel furniture manufacturers, as key components of modern service industry, have become leading service companies concerning China's economic development. Consumer-driven business model and mass customization are becoming important direction of hotel furniture manufacturers’ transformation and upgrade. In a context of fragmented competition and individualized customers’ demand, it is difficult to take advantage of the low cost and high efficiency of mass production, while meeting the customers’ individualized needs. Internet led business increases the difficulty of balancing the offer of large production and customization, because companies face a high cost (Customer to Factory), while the customers’ satisfaction is low (Factory to Customer). Finding a solution to this trade-off is not only a major challenge in the process of company model transformation, but also an important topic that has not yet been studied in depth. Based on Fanqing Hotel Furniture Company’s empirical case of solving the contradiction between individualized demand and mass production, this thesis studies the evolution of hotel furniture manufacturers’ (HFM) innovation ecosystem and the value co-creation mode. The C2F2C (Customer to Factory to Customer) strategy of Fanqing was constructed based on both company innovation ecosystem theory and customer value co-creation theory. By implementing the C2F2C strategy, Fanqing has realized standardization, informatization and lean production, and also fulfilled customers’ needs and improved their satisfaction. The C2F2C strategy also helps to reduce costs and achieve value co-creation between the company and customers. This thesis explores an effective way to improve technological innovation ability and international competitiveness of HFM in China.As empresas de móveis para hotéis constituem um sector importante no desenvolvimento da indústria de serviços modernos, liderando já a indústria no desenvolvimento económico da China. Seguir um modelo de negócio de personalização em larga escala e orientação para o consumidor aponta ser uma direção significativa a tomar para a transformação e inovação das empresas de serviços. Face à concorrência individualizada e fragmentada na procura de clientes da indústria hoteleira, é difícil oferecer ao cliente uma personalização em larga escala, que permita atingir as vantagens de baixo custo e alta eficiência de produção em volume, atendendo simultaneamente à personalização das necessidades de cada cliente. Na comercialização pela internet é mais difícil equilibrar a oferta de uma produção em larga escala e personalizada, porque é elevado o custo em C2F, mas em contrapartida baixo o nível de satisfação do cliente em F2C. Como suporte empírico, esta tese analisou o caso da empresa de Móveis para Hotéis Fanqing, que resolveu a contradição entre procura individualizada e produção de massa em grande escala, permitindo estudar a evolução para um ecossistema inovador e de criação conjunta de valor entre empresas de móveis e clientes nesta industria de mobiliário para hóteis (HFM). A estratégia da relação cliente para fabricante e deste para cliente (C2F2C) da Fanqing foi desenvolvida com base nas teorias da inovação do ecossistema e da criação de valor conjunta. Ao implementar a estratégia de C2F2C, a Fanqing operou tanto a standardização, a informatização e a produção lean, como a satisfação do cliente preenchendo as suas necessidades. A estratégia C2F2C permite reduzir custos e potencia a criação conjunta de valor entre fabricantes e clientes, explorando uma maneira eficaz de melhorar a capacidade de inovação tecnológica e a competitividade internacional das empresas de móveis para hotéis da China

The second part is an analysis of an online database of mass customization companies. A theoretical framework also serves as a central tool to relate literature review with the empirical findings. RESULTS Findings of the study show that all of the identified success factors were indeed applicable for and present in the case companies. We also conclude that increased customer integration leads to a higher perceived added value of a product/service and in addition we were able to identify four types of drivers that add value in mass customization. Finally we conclude that a collaborative approach is most commonly used among mass customizing companies because it offers the highest extent of customer co-creation, which in turn leads to a higher added value

Enforcing Customization in e-Learning Systems: an ontology and product line-based approach

In the era of e-Learning, educational materials are considered a crucial point for all the stakeholders. On the one hand, instructors aim at creating learning materials that meet the needs and expectations of learners easily and effec-tively; On the other hand, learners want to acquire knowledge in a way that suits their characteristics and preferences. Consequently, the provision and customization of educational materials to meet the needs of learners is a constant challenge and is currently synonymous with technological devel-opment. Promoting the personalization of learning materials, especially dur-ing their development, will help to produce customized learning materials for specific learners' needs. The main objective of this thesis is to reinforce and strengthen Reuse, Cus-tomization and Ease of Production issues in e-Learning materials during the development process. The thesis deals with the design of a framework based on ontologies and product lines to develop customized Learning Objects (LOs). With this framework, the development of learning materials has the following advantages: (i) large-scale production, (ii) faster development time, (iii) greater (re) use of resources. The proposed framework is the main contribution of this thesis, and is char-acterized by the combination of three models: the Content Model, which addresses important points related to the structure of learning materials, their granularity and levels of aggregation; the Customization Model, which con-siders specific learner characteristics and preferences to customize the learn-ing materials; and the LO Product Line (LOPL) model, which handles the subject of variability and creates matter-them in an easy and flexible way. With these models, instructors can not only develop learning materials, but also reuse and customize them during development. An additional contribution is the Customization Model, which is based on the Learning Style Model (LSM) concept. Based on the study of seven of them, a Global Learning Style Model Ontology (GLSMO) has been con-structed to help instructors with information on the apprentice's characteris-tics and to recommend appropriate LOs for customization. The results of our work have been reflected in the design of an authoring tool for learning materials called LOAT. They have described their require-ments, the elements of their architecture, and some details of their user inter-face. As an example of its use, it includes a case study that shows how its use in the development of some learning components.En la era del e¿Learning, los materiales educativos se consideran un punto crucial para todos los participantes. Por un lado, los instructores tienen como objetivo crear materiales de aprendizaje que satisfagan las necesidades y ex-pectativas de los alumnos de manera fácil y efectiva; por otro lado, los alumnos quieren adquirir conocimientos de una manera que se adapte a sus características y preferencias. En consecuencia, la provisión y personaliza-ción de materiales educativos para satisfacer las necesidades de los estudian-tes es un desafío constante y es actualmente sinónimo de desarrollo tecnoló-gico. El fomento de la personalización de los materiales de aprendizaje, es-pecialmente durante su desarrollo, ayudará a producir materiales de aprendi-zaje específicos para las necesidades específicas de los alumnos. El objetivo fundamental de esta tesis es reforzar y fortalecer los temas de Reutilización, Personalización y Facilidad de Producción en materiales de e-Learning durante el proceso de desarrollo. La tesis se ocupa del diseño de un marco basado en ontologías y líneas de productos para desarrollar objetos de aprendizaje personalizados. Con este marco, el desarrollo de materiales de aprendizaje tiene las siguientes ventajas: (i) producción a gran escala, (ii) tiempo de desarrollo más rápido, (iii) mayor (re)uso de recursos. El marco propuesto es la principal aportación de esta tesis, y se caracteriza por la combinación de tres modelos: el Modelo de Contenido, que aborda puntos importantes relacionados con la estructura de los materiales de aprendizaje, su granularidad y niveles de agregación, el Modelo de Persona-lización, que considera las características y preferencias específicas del alumno para personalizar los materiales de aprendizaje, y el modelo de Línea de productos LO (LOPL), que maneja el tema de la variabilidad y crea ma-teriales de manera fácil y flexible. Con estos modelos, los instructores no sólo pueden desarrollar materiales de aprendizaje, sino también reutilizarlos y personalizarlos durante el desarrollo. Una contribución adicional es el modelo de personalización, que se basa en el concepto de modelo de estilo de aprendizaje. A partir del estudio de siete de ellos, se ha construido una Ontología de Modelo de Estilo de Aprendiza-je Global para ayudar a los instructores con información sobre las caracterís-ticas del aprendiz y recomendarlos apropiados para personalización. Los resultados de nuestro trabajo se han plasmado en el diseño de una he-rramienta de autor de materiales de aprendizaje llamada LOAT. Se han des-crito sus requisitos, los elementos de su arquitectura, y algunos detalles de su interfaz de usuario. Como ejemplo de su uso, se incluye un caso de estudio que muestra cómo su empleo en el desarrollo de algunos componentes de aprendizaje.En l'era de l'e¿Learning, els materials educatius es consideren un punt crucial per a tots els participants.
