Re-defining data visuals for an efficient and sustainable food waste management

Singh, Suhas January 2017 (has links)
The use of visual data representation is increasing the possibilities to exchange information and communicate indifferent contexts all over the world. Communicating food wastage visually to influence consuming patterns isone of these possibilities. Food wastage is currently a much-prioritized topic in Sweden as well as globally due toits negative impacts on society, environment and the economy, and therefore there is much need to bringinnovative solutions supporting reduction of food waste. This thesis presents a qualitative research based on a casestudy of food waste management at Sala municipality in Sweden while exploring the current visual datarepresentation techniques and its further potential to make food waste management more sustainable. The researchframework used in this thesis is based on visual rhetoric and the innovation theories. The thesis analyzes foodwastage from an international perspective, its connection to sustainable development goals and how MatomaticAB uses a visual data representation tool to address food wastage.The thesis further explains how the users associated with Sala municipality interpret the existing tool, thechallenges they face and review their expectations to build a new visual data representation model. The results ofquestionnaires filled by user’s, state that 50% of the respondents understand the current tool to its full capacityand only 50% of the respondents are satisfied with the overall tool. When it comes to the choice of datapresentation 67% of the users showed interest in use of infographics instead of the conventional bar graphs, andtherefore some parameters like, making the tool more interesting using infographics, user friendly by limiting thedata displayed and interactive by giving user options to explore further as per their liking, were thought whiledesigning the new visual data representation model.

Nedfrysning av nötkött – ett sätt att minska matsvinn? : Konsumenters inställning till att köpa nötkött som frysts ner dagen innan bäst före datum har passerat kopplat till food literacy. / Freezing beef - a way to reduce food waste? : Consumers' attitude to buying beef that has been frozen the day before best before date has passed linked to food literacy.

Mårtensson, Ida, Nordström, Therese January 2019 (has links)
Inledning: Matsvinn bidrar till en negativ klimatpåverkan och svinnet av animalier, speciellt nötkött, genererar stora mängder onödigt växthusgasutsläpp per kilo. Att minska svinnet av animalier bör prioriteras för att snabbt minska växthusgasutsläppen. Syfte: Syftet är att undersöka konsumenters inställning till att köpa nötkött som frysts ner dagen innan bäst före datum har passerat i ett försök att minska köttsvinn. Vidare studeras om matrelaterade kunskaper, färdigheter och beteenden, sammanfattade i begreppet food literacy, påverkar inställningen till att köpa nötkött som frysts ner dagen innan bäst före datum har passerat. Material och metod: Data samlades in via en webbenkät och en fokusgrupp. Databearbetning och analys av den kvantitativa datan utfördes i Excel där chitvå-test användes som statistisk metod. Den kvalitativa datan transkriberades och analyserades med hjälp av kodning och tematisering. Resultat: Den kvantitativa datan visar en positiv trend där majoriteten av konsumenterna kan tänka sig att köpa nötkött som frysts ner dagen innan bäst före datum har passerat. Resultaten visar att graden av food literacy ökar med åldern. Faktorer som visar sig vara betydelsefulla för konsumenter är pris, kvalitet, förpackning och ursprung. Slutsats: Majoriteten av respondenterna oavsett ålder är positivt inställda till att köpa nötkött som frysts ner dagen innan bäst före datum har passerat. Resultatet pekar åt att andelen respondenter med hög grad av food literacy ökar med ålder och faktorer som styr vid inköp av nötkött som frysts ner dagen innan bäst före datum har passerat är pris, kvalitet, förpackning och ursprung. / Introduction: food waste contributes to a negative climate impact and the meat wastage, especially beef, generates large amounts of greenhouse gas emissions per kilogram beef. Reducing animal wastage should be a priority in order to quickly reduce greenhouse gas emissions. Aim: The aim is to investigate consumers' attitude to buying beef that has been frozen the day before the best before date has passed in an attempt to reduce the meat wastage. The study also investigates whether food-related knowledge, skills and behaviors, summarized in the concept food literacy, affect the attitude of buying beef that has been frozen the day before the best before date has passed. Method: Data was collected using a web-questionnaire and a focus group. The processing and the analysis of the data was performed in Excel using Chi-Square tests. The qualitative data was transcribed and analyzed using coding and thematization. Results: The quantitative data shows a positive trend where the majority of consumers can see themselves buying beef that has been frozen the day before the best before date has passed. The results show that the level of food literacy increases with age. Factors that prove to be important for consumers are price, quality, packaging and origin. Conclusion: The majority of respondents regardless of age are positive about buying beef. The result indicates that the proportion of respondents with a high degree of food literacy increases with age and factors that prove to be important for consumers when buying beef are price, quality, packaging and origin.

Production System waste reduction using Value stream mapping : An Industrial case study / Production System waste reduction using Value stream mapping : An Industrial case study

Devarakonda, Rakesh Raghavendra, Ramachandrareddy, Sumanth January 2019 (has links)
The rapid rise in global population and market demands have mandated industries to introduce better and quality products to meet up their rushing needs. However, achiev-ing such goals need optimal production system and robust strategies. Exploring in depth it can be visualized that most of the manufacturing set ups suffers losses or relatively lower benefits due to improper and high wastages. Hence it is very important for man-ufacturing industries to explore the techniques which help them to improve their pro-duction system. The key techniques from Lean Manufacturing (LM) such as Value Stream Mapping (VSM) and Ishikawa diagram were explored in this work for enhanc-ing production capacity, reducing rework, reducing wastages and arriving to a well-defined optimal process flow which in turn help in achieving higher productivity. How-ever, the implementation of Lean and Value stream mapping depends on the production scale and has its own significance to different manufacturing setup. With that motive, in this thesis work the emphasis was made on exploring VSM technique for better pro-duction optimization in manufacturing sector.

Ciência, técnica e experiências sociais na pesquisa e na extensão universitárias: possibilidades de diálogos entre saberes / Science, technique and social experiences in university research and extension: dialogue possibilities between knowledge.

Silva, Márcia Regina Farias da 13 March 2009 (has links)
O presente trabalho teve por objetivo registrar os diálogos entre os diferentes campos de conhecimentos, que serviram de postulado para orientar as ações do projeto de pesquisa e extensão, Avaliação Técnica, Econômica e Socioambiental da Atividade Artesanal no Quilombo de Ivaporunduva, Vale do Ribeira (SP), bem como aportar as possíveis contribuições deste Projeto para estreitar o diálogo entre o conhecimento científico e os saberes originários das experiências e das práticas dos componentes do Grupo de Artesanato da comunidade de Ivaporunduva, localizada no município de Eldorado, Vale do Ribeira, estado de São Paulo, Brasil. Realizou-se análise de documentos produzidos pelo Projeto; foram feitas entrevistas com técnicos, professores e/ou pesquisadores e alunos, e com membros do Grupo de Artesanato; além disso, realizaram-se observações das ações do Projeto na academia e na comunidade. Verificouse que as atividades desenvolvidas no âmbito acadêmico contribuíram para construção gradual da prática inter e/ou transdisciplinar, na medida em que as ações do Projeto necessitaram reunir diferentes áreas do saber para resolver dificuldades técnicas encontradas para a consolidação da atividade. Observou-se ainda que há graus de comprometimento variados, entre os diferentes profissionais, de campos disciplinares distintos. Contudo, a abertura por parte do corpo discente vem sendo um veículo importante para a interlocução de saberes, que tem estimulado o exercício da prática inter e/ou transdisciplinar. Constatou-se que a Universidade, enquanto produtora e disseminadora de conhecimentos requer mudanças, no sentido de promover a aproximação dos campos disciplinares, tendo em vista a construção de um conhecimento integrado. Já no âmbito comunitário foi possível constatar que, as ações do Projeto contribuíram para aproximar os saberes técnico-científicos das experiências e das práticas do Grupo de Artesanato, visando a resolução de problemas de ordem técnica, de comercialização e de gestão que inviabilizam a consolidação da atividade artesanal naquela comunidade. Conclui-se, portanto, que a interlocução entre diferentes campos do conhecimento, bem como o diálogo entre o conhecimento científico e outros saberes pode contribuir para o debate epistemológico e, por conseguinte para construção de um conhecimento integrador. / The aim of this research work was to register the dialogues between the different knowledge fields, which served to direct the actions of the research and extension project, Technical, Economic, Social and Environmental evaluation of the Handicraft activities inside the Ivaporunduva Quilombo, Vale do Ribeira (SP), as well as to signed the possible contributions of this project to close the dialogue between scientific knowledge and knowledge came from the experience of the members of the Ivaporunduva community, located in El Dorado, Vale do Ribeira, São Paulo State, Brazil. The documents elaborated by the project were analyzed; as well as were made interviews with technicians, professors and/or researchers and students involved in the project, and with the members of the Handicraft Group. Besides, observations of the project actions inside the academy and the community were made. This analysis checked out the activities developed in the academic sphere that contributed to the grade construction of an inter-disciplinary and/or trans-disciplinary practice, since the project actions needed to bring together different knowledge areas to solve technical difficulties to allow the consolidation of the activity. Hence, this research work, noticed the varied grades of commitment existing among the different professionals from different subject fields. However, the open attitudes of the university students have been an important vehicle to the knowledges dialogue, what have been stimulating the inter-disciplinary and/or trans-disciplinary practice. There were realized that the university, as producer and spreader of knowledge, needs changes, to promote the approximation between subject fields, having in view the construction of an including knowledge. Inside the communitarian sphere was possible to realize that the project actions contributed to approximate the technical-scientific knowledge and the Handicraft Group activities, looking to solve technical, sale and management problems that produced difficulties to establish the craftwork activity with in the community. Therefore, this conclude that the dialogue between different knowledge fields as well as the dialogue between the scientific knowledge and other kinds of knowledge could contribute to the epistemic debate and, therefore, to the construction of an including knowledge.

Made available in DSpace on 2015-05-08T14:53:31Z (GMT). No. of bitstreams: 1 arquivototal.pdf: 2225329 bytes, checksum: aeb2b58ce9683163296978cd44822c1c (MD5) Previous issue date: 2012-08-30 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This dissertation concerns the application of the Activity Based Costing method (ABC) as a tool to hold cost reduction in service companies. The first step was the contextualization of the method importance followed by the justification of the research. After that, a literary review was made and it involved value chain, cost management, ABC method, time-driven ABC, target costing, kaizen costing, value stream mapping and tourism. Based on the researched literature this survey could be separated in three phases: (1) application of the costing method in service costing, (2) application of the value stream mapping in services with a greater incidence of indirect costs and (3) suggestion of a more appropriated cost reduction technique to the service in analysis. This research is exploratory and applied; it is also focused on three case studies in service, two restaurants and a travel agency. The results obtained with the survey indicate service costs and point out the ABC method as an auxiliary tool in the search for cost reduction, having in mind that the more accurate treatment of indirect costs provided by ABC method facilitated the identification of the services which needed wastage analysis. In the last chapter the final considerations related to the research are presented as well as suggestions for future searches. / Esta dissertação trata da aplicação do método de custeio ABC (Activity Based Costs) como ferramenta de suporte à redução de custos em empresas no setor de serviços. Primeiramente, contextualizou-se a importância do método e justificou-se a realização da pesquisa. Em uma etapa posterior realizou-se uma revisão de literatura sobre cadeia de valor, gestão de custos, método de custeio ABC, time-driven ABC, custeio-meta, custeio kaizen, mapeamento do fluxo de valor, finalizando com uma breve revisão no setor de serviços com ênfase na atividade turística. Baseado na literatura pesquisada dividiu-se este estudo de caso em três fases: (1) Aplicação do método de custeio ABC em três empresas do setor serviços, (2) Aplicação do mapeamento do fluxo de valor nos serviços com maiores incidências de custos indiretos e (3) sugestão de técnica de redução de custos mais apropriada para o serviço em análise. A pesquisa possui natureza exploratória e aplicada, focada em um estudo de três casos no setor de serviços, dois restaurantes e uma agência de viagens. Os resultados obtidos na pesquisa indicam os custos dos serviços prestados e aponta o ABC como uma ferramenta auxiliar na busca pela redução de custos, pois o tratamento mais acurado dos custos indiretos fornecido pelo ABC facilitou a identificação dos serviços que necessitavam de uma análise nos desperdícios. No último capítulo são apresentadas as considerações finais acerca da pesquisa e sugestões de pesquisas futuras.

No. of bitstreams: 1 Ana Melicia Moraes de Souza.pdf: 1281302 bytes, checksum: 154be069acdc511537bb408a02af67c2 (MD5) Previous issue date: 2017-02-23 / This research has, as a study object, the use of school materials in a state school from São Paulo. The problem of the investigation is to know if the management of this kind of material follows the sustainability principles. It started from the hypothesis that the school materials waste and irregular use may be attached to the society consumption pattern and, also, that such materials, which is distributed by the public power, may be not being used correctly, what becomes evident through the apparent waste and punctual actions, distant from a critical view and sustainable attitudes, from the environmental point of view, by the educational agents. Seeking to understand the advances of the school materials delivery, this research proposes to carry out a legal support assessment about them, identifying controversies and contradictions that surround the resources which are available in the educational environment. The methodology includes documental analysis, focus groups with teachers and students, interview with the management team, within the scope of a case study, in a São Paulo state school. The main theoretical critical reference was the Frankfurt school Critical Theory. In the analysis result of the involved persons’ speech, we could observe that the school materials management follows the logic of the exacerbated consumption, characteristic from this capitalist society, since these materials end up not being used with sustainability principles. We have also realized that the formation is weakened, by having the theory and praxis articulation committed in its development. Finally, it is possible to affirm that there are contradictions about the school materials delivery, use and discard made by the attended community, since the formation is the main question. It is possible to say that the public policy reflects very little on the concerns about the sustainability which becomes evident in the documentary analyses. Without a users’ critical reflection, the school materials end up being wasted and discarded in an irregular way, causing damages in many spheres. The research is concluded with an intervention proposal which permits advances in the use of these materials utilized by this school community, in order to promote awareness and the viability of an educational performance based on sustainability criteria. / Esta investigación tiene como objeto de estudio la utilización del material escolar en una escuela estatal de São Paulo / Brasil. El problema de la investigación es saber si la gestión de este tipo de material sigue con los principios del desarrollo sostenible. Partió de las hipótesis de que el despilfarro y el uso irregular de materiales escolares pueden estar conectados a los patrones de consumo de la sociedad y también que dicho material distribuido por el gobierno puede no estar siendo utilizado correctamente, lo que se evidencia por medio del aparente despilfarro y de acciones puntuales desvinculadas de una actitud crítica y sostenibles, bajo el punto de vista del medio ambiente, según los educadores. En la búsqueda de la comprensión de los avances en la distribución de material escolar, la investigación se propone llevar a cabo un estudio del apoyo legal en ellos para identificar polémicas y contradicciones que rodean a los recursos que están disponibles en el entorno escolar. La metodología incluye el análisis de documentos, grupos focales con profesores y con estudiantes, entrevistas con el equipo de gestión, como parte del estudio de caso en esta escuela pública de São Paulo. El principal marco teórico fue la Teoría Crítica de la Escuela de Frankfurt. En el resultado del análisis de los discursos de los involucrados, se observó que la gestión de los materiales escolares sigue la lógica del consumo exagerado, característica de esta sociedad capitalista, ya que estos materiales no terminan siendo utilizados con los principios sostenibles. También observamos que la formación se encuentra debilitada, y la articulación entre la teoría y la praxis comprometida en su desarrollo. Por último, es posible decir que hay contradicciones en cuanto a la distribución, la utilización y el desecho de materiales escolares realizados por esta comunidad que se sirve de la formación como cuestión principal. Es posible decir que las políticas públicas poco reflejan las preocupaciones sostenibles y así se queda más evidente en los documentos genéricos y en los tribunales superiores. Sin una reflexión crítica de los usuarios, el material escolar termina siendo despilfarrado y desechado de manera irregular, causando perjuicios en diversos ámbitos. La investigación se completa con la propuesta de una intervención para permitir avances en el uso de estos materiales para esta comunidad escolar con el fin de promover concientización y la viabilidad de una actuación educativa basada en criterios sustentables. / Esta pesquisa tem como objeto de estudo a utilização do material escolar em uma escola estadual de São Paulo. O problema da investigação é saber se a gestão desse tipo de material segue com princípios de sustentabilidade. Partiu das hipóteses de que o desperdício e o uso irregular do material escolar pode estar ligado ao padrão de consumo da sociedade e, também, de que tal material distribuído pelo poder público pode não estar sendo utilizado corretamente, o que se evidencia por meio do aparente desperdício e de ações pontuais descoladas de uma visão crítica e atitudes sustentáveis, sob um ponto de vista ambiental, por parte dos agentes educativos. Na busca por compreender os avanços na distribuição dos materiais escolares, a pesquisa propõe realizar um levantamento do suporte legal sobre eles, identificando polêmicas e contradições que cercam os recursos que estão disponíveis no ambiente escolar. A metodologia inclui análise documental, grupos focais com professores e com estudantes, entrevistas com a equipe gestora, no âmbito de um estudo de caso, em uma escola estadual de São Paulo. O principal referencial teórico foi a teoria crítica da escola de Frankfurt. No resultado das análises dos discursos dos envolvidos, observamos que a gestão dos materiais escolares segue a lógica do consumo exacerbado, característico desta sociedade capitalista, visto que esses materiais acabam não sendo utilizados com princípios de sustentabilidade. Constatamos também que a formação encontra-se fragilizada, tendo a articulação teoria e práxis comprometida em seu desenvolvimento. Finalmente, é possível afirmar que existem contradições quanto à distribuição, ao uso e ao descarte de materiais escolares feito por essa comunidade atendida, sendo a formação a principal questão. É possível afirmar que as políticas públicas pouco refletem as preocupações para com a sustentabilidade, o que fica evidente nas análises documentais. Sem uma reflexão crítica dos usuários, o material escolar acaba sendo desperdiçado e descartado de forma irregular, causando prejuízos em várias esferas. A pesquisa é concluída com a proposta de intervenção que permite avanços no uso desses materiais utilizados por essa comunidade escolar, a fim de promover conscientização e a viabilidade de uma atuação educativa pautada em critérios de sustentabilidade.

Reducción de mermas por perecibilidad mediante Lean Manufacturing en una PYME del sector cárnico peruano / Reduction of losses due to perishability through Lean Manufacturing in an SME in the Peruvian meat sector

Castro Arroyo, Anthony Jair, Rojas Benites, Sergio Junior 23 November 2020 (has links)
En el rubro alimenticio, debido al trabajo con insumos perecibles, el desperdicio de comida en su cadena de suministro es inevitable. Este problema afecta a una MYPE dedicada al procesamiento cárnico en Lima, Perú. Resulta que en promedio el 15.78% de inventarios se desperdician, lo que asciende a un 8% en su facturación anual. La investigación evidencia que esto ocurre por tres motivos: Error en la programación de la producción, productos en proceso no rotativos y se compra materia prima de más. A través de las herramientas Kanban y 5s, en conjunto con un método de pronóstico de la demanda y el Kardex se espera la reducción del 7% de mermas actual en el almacén. La validación del modelo propuesto se realiza mediante el programa Arena Simulator, en el cual se logró reducir la merma a niveles óptimos. La viabilidad se aprueba mediante los resultados favorables de las consideraciones económicas como Valor Actual Neto (VAN), la Tasa Interna de Retorno (TIR) y la Relación Beneficio-Costo (RBC) y, por último, se evalúan el impacto ambiental y organizacional. Se concluye que la implementación del modelo presenta un impacto factible en los parámetros mencionados y surge necesidad de mantenerlo a largo plazo. / In the food industry, due to working with perishable inputs, food waste in your supply chain is inevitable. This problem affects an MYPE dedicated to meat processing in Lima, Peru. It turns out that on average 15.78% of inventories are wasted, which amounts to 8% in their annual turnover. The research shows that this occurs for three reasons: Error in the production scheduling, non-rotating products in process and raw material is purchased too much. Through the Kanban and 5s tools, in conjunction with a demand forecasting method and the Kardex, a reduction of 7% of current losses in the warehouse is expected. The validation of the proposed model is carried out through the Arena Simulator program, in which it was possible to reduce the waste to optimal levels. The viability is approved by means of the favorable results of the economic considerations such as Net Present Value (NPV), the Internal Rate of Return (IRR) and the Benefit-Cost Ratio (RBC) and, finally, the environmental and organizational impact are evaluated. It is concluded that the implementation of the model has a feasible impact on the mentioned parameters and there is a need to maintain it in the long term. / Trabajo de investigación

Effektivisering vid hantering av prefabricerade stomelement / Efficiency in handling prefabricated concrete elements

Hauke, Christopher, Johansson, Björn January 2017 (has links)
Efterfrågan på bostäder är idag större än på länge samtidigt som byggbranschen kämpar med pressade byggtider och låga vinstmarginaler. Vinstmarginalen kan ökas genom att effektivisera logistiken och eliminera onödiga kostnader som uppstår i samband med bristande planering. Syftet med rapporten är att hjälpa Peab att identifiera var onödiga kostnader uppstår i samband med hantering av prefabricerade stomelement. Detta sker genom att jämföra arbetet med logistikfrågor på två likvärdiga Peab-projekt, vilka är KTH-studentbostäder samt Roddaren och Simmaren. Resultatet bygger till största del på djupgående intervjuer med nyckelpersoner på respektive projekt. En enkätundersökning gjordes som ett komplement till resultatet från intervjuerna. Rapporten visar att arbetet med logistikfrågor skiljer sig mellan de två projekten. Slöseri på grund av brister i den interna kommunikationen finns på båda arbetsplatserna. Gemensamt är även slöseri till följd av avsaknad av tydliga rutiner för dokumentation av dolda felkostnader. Det största identifierande slöseriet på den enskilda arbetsplatsen var slöseri till följd av fel lastordning på projekt Roddaren och Simmaren vilket lett till både synliga och dolda kostnader. / Demand for housing is today greater than in a long time, whilst the construction industry is struggling with the pressure to shorten construction schedules and low profit margins. The profit margin can be increased by streamlining logistics and eliminating unnecessary costs arising from lack of planning. The purpose of the report is to help Peab identify where unnecessary costs arise in the handling of prefabricated concrete elements. This is done by comparing the work on logistics issues to two equivalent Peab-projects, KTH-studentbostäder and Roddaren and Simmaren. Results are largely based on in-depth interviews with key people on each project. A survey was conducted as a complement to the results of the interviews. The report shows that the work on logistics issues differs between the two projects. Wastage due to shortcomings in internal communication are found at both workplaces. They also have in common wastage due to lack of clear procedures for documenting the cost of hidden errors. The biggest identifiable waste at the individual workplace was waste as a result of wrong loading order on the Roddaren and Simmaren projects, which led to both visible and hidden costs.
