Ana Claudia Tassi Amancio 22 September 2016 (has links)
A atual pesquisa faz parte do grupo de pesquisa, cadastrado no Conselho Nacional de Desenvolvimento Científico e Tecnológico, sobre moda na cadeia têxtil, tendo como foco as questões sociais da cadeia produtiva da manufatura do vestuário de moda. O mercado de produto de vestuário de moda massificado enfrenta grandes dificuldades com consumidores que desejam produtos personalizados e serviços rápidos, eficientes e, ao mesmo tempo, conforme suas necessidades. Cada vez mais as empresas do setor de vestuário necessitam de gestões eficientes a partir de novas estratégias alinhadas com as novas tecnologias visando o desenvolvimento, a produção e a comercialização do produto com o objetivo de atender a demanda do mercado consumidor. As empresas que apostam nesses produtos personalizados estão descobrindo que as soluções convencionais poderão ser extintas e que há necessidades de novas práticas para estarem aptos a desenvolver os produtos e serviços que atendam às necessidades e aos desejos dos seus consumidores. O processo de diferenciação e personalização na manufatura do vestuário da moda ocorre de forma cada vez mais acelerada. Neste contexto, a indústria em seu processo de desenvolvimento de novos produtos se antecipa buscando descobrir tendências, a fim de produzir de forma otimizada e atender a demanda de consumidores específicos que desejam ser percebidos de forma cada vez mais individualizada. Esta pesquisa tem como objetivo geral estudar a diferenciação e personalização da produção através da customização em massa, atendendo a demanda de um determinado público-alvo. Em relação aos procedimentos metodológicos, foram realizadas pesquisas bibliográficas que resultaram na fundamentação teórica, a qual auxiliou na construção dos questionários com perguntas semiestruturas, a serem aplicadas nos estudos de casos com empresas que utilizam estratégias de diferenciação do produto, através da customização em massa. Após, foi possível analisar os casos, bem como comparar por meio de quadros, as estratégias e processos utilizados pelas por estas empresas. Os resultados permitiram confirmar quais estratégias e processos são necessários para prática efetiva do produto diferenciado e personalizado através da customização em massa. Portanto, este estudo se justifica pela importância social e econômica do setor têxtil e da moda e pela escassez de bibliografia acerca do tema. Espera-se assim que essa pesquisa possa lançar luz em um campo pouco pesquisado, além contribuir com referencial bibliográfico / The present research is part of the research group, registered with the National Council for Scientific and Technological Development, on fashion in the textile chain, focusing on social issues of the productive chain of manufacture of fashion apparel. The massiveness fashion apparel product market faces great difficulties with consumers who want customized products and fast, efficient and at the same time, as needed. More and more clothing sector firms need efficient efforts from new strategies aligned with new technologies for the development, production and marketing of the product in order to meet the demand of the consumer market. The companies that invest in these customized products are finding that conventional solutions may be extinct and that there is need for new practices to be able to develop products and services that meet the needs and desires of its consumers. The differentiation and customization process in the fashion garment manufacturing is increasingly accelerated rate. In this context, the industry in the development process of new products anticipates seeking to discover trends in order to produce optimally and meet the demand for specific consumers who wish to be perceived increasingly individualized. This research has the general objective to study the differentiation and customization of production through mass customization, meeting the demand of a targeted audience. Regarding the methodological procedures were conducted literature searches that resulted in the theoretical foundation, which helped build the questionnaires with semi-structured questions, to be applied in the case studies with companies using product differentiation strategies through mass customization. After it was possible to analyze the cases and compare through frameworks, strategies and processes used by these companies. The results confirm what strategies and processes are needed for effective practice of differentiated and personalized product through mass customization. Therefore, this study is justified by the social and economic importance of the textile sector and fashion and the lack of literature on the subject. It is hoped that this research will shed light on a little-researched field, besides contributing to bibliographic references

Platform based approach for economic production of a product family

Choubey, Anand M January 1900 (has links)
Master of Science / Department of Industrial & Manufacturing Systems Engineering / David H. Ben-Arieh / In present competitive market, there is growing concern for ascertaining and fulfilling the individual customer’s wants and needs. Therefore, the focus of manufacturing has been shifting from mass production to mass customization, which requires the manufacturers to introduce an increasing number of products with shorter life span and at a lower cost. Also, another challenge is to manage the variety of products in an environment where demands are stochastic and the lead times to fulfill those demands are short. The focus of this thesis is to develop and investigate platform based production strategies, as opposed to producing each product independently, which would ensure the economic production of the broader specialized products with small final assembly time and under demand uncertainty. The thesis proposes three different platform based production models. The first model considers the economic production of products based on a single platform and with forecasted demands of the products. The model is formulated as a general optimization problem that considers the minimization of total production costs. The second model is the extension of the first model and considers the production of products based on multiple platforms and considers the minimization of total production costs and the setup costs of having multiple platforms. The third model is also an extension of the first model and considers the demands of the products to be stochastic in nature. The model considers the minimization of total production costs and shortage costs of lost demands and holding cost of surplus platforms under demand uncertainties. The problem is modeled as a two stage stochastic programming with recourse. As only the small instances of the models could be solved exactly in a reasonable time, various heuristics are developed by combining the genetic evolutionary search approaches and some operations research techniques to solve the realistic size problems. The various production models are validated and the performances of the various heuristics tailored for the applications are investigated by applying these solution approaches on a case of cordless drills.

Customização em massa aplicada ao setor de serviços

Vieira, João Francisco da Fontoura January 2014 (has links)
Atualmente, a customização apresenta-se como um importante diferencial competitivo para as empresas. No entanto, ao consumir bens customizados, o cliente está, em geral, sujeito ao pagamento de altos preços e à espera de longos tempos de entrega. Portanto, quanto mais as empresas desenvolverem soluções customizadas com altos níveis de eficiência, maior será a tendência de conquista do cliente. Nesse cenário, a customização em massa (CM), que está relacionada à produção de altos volumes de produtos e serviços customizados a um custo semelhante ao de itens padronizados, surge como solução. Verifica-se, porém, que, apesar da importância do setor de serviços no contexto atual, existe pouco conhecimento sobre a utilização da CM neste ramo de atividade. Dado isso, o objetivo desta dissertação é aplicar conceitos da CM, já difundidos na manufatura, no setor de serviços. Para atingir o objetivo, foram desenvolvidos três artigos. No primeiro artigo, foi realizada uma revisão da literatura a fim de identificar linhas de pesquisa já existentes sobre o tema e oportunidades possíveis de serem exploradas. No segundo artigo, foi proposta uma classificação para a customização de serviços, apresentando diversos tipos de customização possíveis de serem realizados nesse setor. No terceiro artigo, foi desenvolvido um dos tipos de customização apresentado no artigo anterior (mais especificamente, o tipo “Modularização e Plataforma de Serviços”) através da adaptação de um método de modularização, já utilizado para modularizar produtos, para o setor de serviços. Como conclusão geral, confirmou-se a expectativa de que a CM em serviços está em um nível baixo de maturidade, pois existem poucos estudos desenvolvidos sobre o tema. Além disso, verificou-se que as poucas soluções propostas pela literatura raramente são viáveis de serem utilizadas pelas empresas. Por fim, acredita-se que os habilitadores da CM em serviços devem considerar as características específicas desse setor, visto que, atualmente, os estudos introduzem no setor de serviços o que já foi desenvolvido para produtos, sem, no entanto, considerar as diferentes características desses dois setores. / Customization has been viewed as an important competitive advantage by companies. However, when consuming customized goods, customers are likely to pay higher prices and wait longer for the items purchased. Therefore, the more the companies develop customized solutions with high levels of efficiency, the greater the tendency to hold customers. In such context Mass Customization (MC), defined as the production of high volumes of customized products and services at mass production costs, arises as a solution. It is verified, however, that, despite the importance of the service industry, there is insufficient knowledge about the use of MC in such application context. The objective of this thesis is to apply MC concepts, already used in the manufacturing sector, in the service industry. We achieve that through the papers that compound this document. In the first paper, we present a literature review on MC in services and point to promising research opportunities. In the second paper, we propose a classification for service customization, presenting many types of customization feasible to be carried out in that sector. In the third paper we developed one of the customization types proposed in the second paper (namely, "Modularization and Platform of Services") by adapting a modularization method already used in manufacturing to the service sector. In general, we concluded that MC in the service industry is indeed at a low maturity level. Furthermore, it was found that the solutions proposed by authors are rarely applicable in practice. Finally, it is believed that MC enablers in the service industry should consider its specific characteristics instead of using solutions developed for products, without considering the specifics of the service industry.

Kundenindividuelle Turnschuhe - Individualisierung, Mass Customization und Kundenwünsche - Theoretische Grundlagen und empirische Befunde -

Sewart, Bettina 23 October 2003 (has links)
Eine zunehmende Individualisierung der Gesellschaft und die daraus resultierende Veränderung der Kundenansprüche wirken sich zwangsläufig auch auf die Produktion und die Vermarktung von Unternehmen aus. Die Autorin setzt sich mit einer besonderen Strategie auseinander, mit der Unternehmen versuchen, der zunehmenden Individualisierung von Kundenwünschen gerecht zu werden: mit der Mass Customization. Inwieweit sich die Mass Customization tatsächlich dazu eignet, individuelle Kundenwünsche zu befriedigen und in welchem Maße sie von Kunden akzeptiert wird, untersucht die Autorin am Beispiel kundenindividueller Turnschuhe.

Loo, Daniel, Ekersund Norman, Miranda January 2022 (has links)
Denna studie ämnar att bidra till kunskap till skapandet av en regelmotor för hanteringen av verksamhetsregler ur ett systemutvecklarperspektiv. Studien har utförts hos företaget Mobilaris som själva har identiferat ett potentiellt behov av verktyg för att på bättre sätt hantera verksamhetsregler. Innan studien påbörjades, så utfördes en förstudie då regelmotor som skulle nyttjas valdes ut. Studien har genom en designstudie där en regelmotor iterativt har utvecklats för att passa systemet Planning & Scheduling™. Datainsamlingen är gjort genom enkäter och semistrukturerade intervjuer som föregåtts av en presentation av artefakten. Enkäterna har följt en kvantitativ modell som kallas System Usability Scale. De semistrukturerade intervjuerna har sedan analyserats med hjälp av en innehållsanalys för att kunna identifera behoven och göra artefakten bättre. Resultatet av studien är riktlinjer som med fördel kan användas när man implementerar en regelmotor för ett resursplanneringssystem. Studien har identiferat nio teoretiska koncept varav åtta har kunnat bekräftas utifrån empirin. Det har också identiferats fyra nya designprinciper som anses göra regelmotorn bättre. / This study aims to contribute knowledge to the creation of a rule engine for the management of business rules from a system developer perspective. The study was conducted at a company called Mobilaris, which has identifed a potential need for tool to better manage business rules in one of their systems. Before the study began, a pilot study was carried out to select the rule engine that where going to be used in the study. The study has through a design science study where a rule engine has iteratively developed to fit the system Planning & Scheduling™. The data collection is done through surveys and semi-structured interviews that are preceded by a presentation of the artifact. The surveys follow a model called the System Usability Scale. The semi-structured interviews was then analyzed using a content analysis to be able to identify needs to make the artifact better. The results of the studies are guidelines that can be benefcial when implementing a rule engine for a resource planning system. The study has identifed nine theoretical concepts, of which eight have been confrmed based on empirical evidence. Four new design principles have also been identifed that are considered to make the rule engine better.

Design automation in industrial order-to-delivery processes : Enabling mass customization of made-to-order products

Olander, Måns, Lüning, Anton January 2021 (has links)
Today's manufacturing industry is heading more and more towards a mass customization approach. This enables customers to individually specify product characteristics and unique design features to fulfill their exact needs. A common way to accomplish this is by means of design automation often used together with knowledge-based engineering. In this thesis, the order-to-delivery process for customized floor gratings at Weland AB is used as a case. This process is currently manual and dependent on several different departments. It results in a time consuming process which is prone to human errors. The purpose is to investigate how design automation can be used and implemented to automate and improve sections of the order-to-delivery process for customized products at an industrial manufacturing company. The objective is to develop a product configurator to automatically generate 3D models and documentation for production and sales support. The configurator succeeded in demonstrating the possible advantages of using design automation. It showed the possibility to reduce the construction department's workload and achieve faster time-to-offer for the sales department. Additionally it is concluded that using a product configurator reduces the risk of human errors and opens up possibilities for other improvements, such as reducing material waste in the production.
