Projeto de sistemas de produção na construção civil utilizando simulação computacional como ferramenta de apoio à tomada de decisãoSchramm, Fábio Kellermann January 2009 (has links)
Embora comum na indústria, o Projeto do Sistema de Produção (PSP) ainda é pouco realizado na construção civil. Estudos anteriores apontaram para a necessidade de empregar ferramentas capazes de modelar e avaliar os efeitos da interdependência, da complexidade e da variabilidade no desempenho dos sistemas de produção na construção, como a simulação computacional, ainda é pouco usada na construção civil. Desta forma, este trabalho teve como objetivo geral propor um modelo para a elaboração do Projeto do Sistema de Produção de empreendimentos da construção civil a partir da utilização da simulação computacional como ferramenta de apoio à tomada de decisão, tendo como ponto de partida o modelo anteriormente desenvolvido. Como estratégia de pesquisa optou-se pela pesquisa construtiva, caracterizada pela implementação de construções inovadoras para a solução de um problema com relevância prática, através do aprendizado baseado na experimentação e na reflexão teórica. A partir de uma revisão de literatura, este trabalho foi dividido em três fases. A fase exploratória consistiu da análise e seleção do software de simulação e de um estudo exploratório. A fase de desenvolvimento consistiu na realização de quatro estudos de caso nos quais avaliou-se o emprego da simulação no PSP. Na fase de análise e reflexão, discutiu-se quatro funções básicas do PSP: promover discussões e questionamentos; incentivar a adoção de uma visão sistêmica; sistematizar, formalizar e registrar decisões; e estabelecer um estado futuro a ser alcançado. Quanto à simulação, seu emprego permitiu o teste de diferentes cenários relacionados a mudanças na estratégia de ataque do empreendimento, ao dimensionamento da capacidade dos recursos de produção entre outros. Propôs-se, ainda, a estratégia de reutilização de modelos como forma de reduzir o tempo de desenvolvimento dos estudos. O modelo proposto, que tem seu escopo limitado a decisões de caráter operacional, divide o PSP em duas fases que não são estanques, devendo sobrepor-se: a fase estática, baseada no modelo anterior de elaboração do PSP; e a fase dinâmica, na qual são desenvolvidos os modelos de simulação e testados cenários para apoiar a tomada de decisão. / Though common in industry, the Production System Design (PSD) is still seldom used by the construction sector. Previous studies have pointed to the need to use tools to model and evaluate the effects of interdependence, complexity and variability in production system performance, such as computer simulation. Thus, this study aimed to propose a model for designing production systems of construction projects based on the use of simulation as a tool to support decision-making, whose starting point is a previously developed model. The constructive research approach is characterized by implementing innovative constructions to solve a specific and practically relevant problem through learning based on experimentation and theoretical reflection. Based on literature review, this study was divided into three phases. The exploratory phase consisted of the analysis and selection of simulation software and an exploratory study. The development phase consisted of four case studies in which the use of simulation in the PSD was evaluated. At the analysis and reflection phase four basic functions of the PSD were discussed: promoting discussion and questions; encouraging the adoption of a systemic view; formalizing and recording decisions; and establishing a state to be reached. The use of simulation allowed the testing of different scenarios related to project installment strategy changes and in the capacity planning of production resource planning capacity among others. A strategy for reusing models was also proposed in order to reduce the development time of the studies. The proposed PSD model, which has its scope limited to decisions of operational nature, is made up of two overlapping phases: the stochastic phase, based on the previously proposed PSD model, and the dynamic phase, in which simulation models are developed and scenarios are tested to support decision-making.

RECONFIGURABLE MANUFACTURING SYSTEM:AN ENABLER FOR COMPETITIVENESS FOR TODAY’S INDUSTRYSohaleh, Hamed January 2017 (has links)
Tough market situation from one side and global competition from another side are persuading companies to search for new manufacturing concepts and try to stay competitive. But “how” to consider “new” manufacturing systems is still a big question mark.This thesis aims to analyze reconfigurability as an enabler for competitiveness in manufacturing systems. The frame of work in this study is “Reconfigurable Manufacturing System” or briefly RMS. In first chapter, some background about reconfigurability has been stated. Then it will continue with research questions, delimitations and expected results.Then the research methodology and challenges for applying RMS have been stated. This chapter explains researchers’ method for data reviewing and data collection. Another focus area in this thesis is SME (Small and Medium size Enterprises). So this report tries also to examine reconfigurability challenges in SMEs. There is a big gap between “ideal” production system and “designing” of this ideal production system. So this thesis tried to increase the knowledge about design of reconfigurable manufacturing systems.In empirical study chapter two case studies have been analysed and as a result a list of challenges for implementing reconfigurable system has been proposed. Then some solutions and methods are proposed in order to answer to challenges. This solutions and methods are then discussed and evaluated.Finally, in last chapter, challenges and prerequisites for implementing reconfigurable manufacturing system in general and for SMEs in specific have been stated. This chapter was ended by expressing future works.

Operational performance driven production system design processIslam, Md Hasibul January 2022 (has links)
The design process of a production system referred to as the production system design process (PSDP) impacts on the operational performancethroughout the lifecycle of the production system, especially on the rampupand operation phases. Despite the impact of activities of PSDP on the operational performance, how to manage the PSDP is still a challenge for manufacturing companies. Earlier research urged to develop a systematic PSDP concerning its impact on the operational performance. This thesis aims to contribute with knowledge of how manufacturingcompanies can manage the PSDP by investigating 1) the enablers in thePSDP that impact on operational performance in ramp-up and operation phases, and 2) how the lean production concept could be adopted tomanage the activities during the PSDP. A case study was conducted in aprocess type manufacturing company, where empirical data were collectedfrom three new production line launching projects by qualitative means. This thesis identifies a set of enablers in the PSDP that potentiallyimpact the operational performance after launching the productionsystem. Empirical findings demonstrate that ensuring proper actions onthe identified enablers in the PSDP could lead to higher operationalperformance of the designed production system. These enablers rangefrom the company´s internal boundary to external vendors, requiring asystematic way to manage these diverse aspects. Adopting the lean production concept in the PSDP context, this thesis proposes a model of Lean Production System Design Process, containing 13 principles andrelevant practices. The proposed model of lean PSDP could be used as a systematic processto manage the activities in the PSDP that would ensure proper actions related to the identified enablers. Empirical findings indicate that adoptionof lean in the PSDP could result in reducing lead time of launching a new production system, and achieving fast ramp-up and desired operational performance considering sustainability aspects. Finally, this thesis demonstrates how the lean PSDP could be a means to achieve a sustainable competitive advantage based on the resource based view theoretical perspective. / Utformningsprocessen av ett produktionssystem, i denna avhandlingkallad produktionssystemets utformningsprocess (PSUP), påverkar denoperativa prestandan under hela produktionssystemets livscykel, särskilt iupprampnings- och driftsfasen. Traditionellt sett ligger fokus underutformningsprocessen på att lansera det nya produktionssystemet vidplanerad tidpunkt och enligt budget. Trots att de aktiviteter somgenomförs i utformningsprocessen påverkar den operativa prestandan idriftsfasen, ägnas ofta mindre uppmärksamhet åt designfasen än vad somvore önskvärt. Tidigare forskning har argumenterat för att utveckla ensystematisk designprocess för framtagning av produktionssystem medsyfte att nå en positiv påverkan på den operativa prestandan. Forskningen i denna avhandling bidrar till att öka kunskapen om hurPSUP kan hanteras och förbättras genom att identifiera: 1) möjliggörare i PSUP som påverkar den operativa prestandan i upprampnings- ochdriftfasen, och 2) hur lean konceptet skulle kunna användas för att hanteraaktiviteterna under PSUP. Resultatet är identifieringen av ett antal faktorer/möjliggörare iproduktionssystemets utformningsprocess (PSUP) som potentiellt kanpåverka den operativa prestandan efter lansering av produktionssystemetoch produktionsstart. Dessa möjliggörare handlar om alltifrån frånföretagets interna gränser till externa leverantörer och kräver ensystematisk procedur för att dra nytta av faktorernas potential. Genom attanvända lean även i PSUP-sammanhanget, föreslås här konceptet Lean PSUP (produktionssystemsutformningsprocess), som innehåller 13 principer och relevanta praxis. Den föreslagna modellen för lean PSUP skulle kunna användas och gestruktur till hanteringen av aktiviteterna i utformningsprocessen.Forskningen indikerar att lean inte bara kan användas i driftsfasen utanäven i utformningen av ett produktionssystem, vilket skulle kunnaresultera i bättre integration mellan olika funktioner, minska ledtiden förutformning och lansering av ett nytt produktionssystem, och uppnå snabbupprampning och önskad operativ prestanda, både avseende produktionoch hållbarhet. Slutligen visar denna avhandling hur lean PSUP kan varaett sätt att uppnå konkurrensfördelar ur ett resursbaserat teoretiskt perspektiv.

Diretrizes para o planejamento e controle da produção em obras de sistemas construtivos metálicosFabro, Fabiana January 2012 (has links)
No setor da construção civil, tem ocorrido um aumento na utilização de sistemas industrializados, dentre eles sistemas construtivos metálicos, visto que o uso desses sistemas contribui para o aumento da velocidade de execução dos empreendimentos e para a redução de desperdícios. Esta mudança tem criado oportunidades para a aplicação de conceitos e métodos de gestão da produção, desenvolvidos em outras indústrias, tais como a Filosofia da Produção Enxuta, que tem trazido muitos benefícios ao setor da construção, tais como redução de desperdícios, aumento da produtividade e da confiabilidade nos prazos de entrega. Entretanto, há poucas pesquisas sobre a utilização de conceitos da produção enxuta no processo de PCP de obras de empresas que fornecem sistemas construtivos metálicos. O presente trabalho tem como objetivo geral propor diretrizes para a concepção e implementação de sistemas de Planejamento e Controle de Produção em obras de empresas que projetam, fabricam e montam sistemas construtivos metálicos. São também propostas adaptações no Sistema Last Planner ao contexto de montagem deste tipo de sistema. A estratégia de pesquisa adotada foi a pesquisa-ação, sendo desenvolvidos cinco estudos empíricos em obras de uma empresa líder neste setor. O trabalho iniciou pela realização de um diagnóstico relativo aos fluxos de materiais e informações entre os principais setores da empresa, assim como análise do processo de planejamento e controle existente no processo de montagem. Na sequência, foram definidas e implementadas melhorias no processo de PCP em três obras da empresa. Os principais resultados obtidos pela pesquisa estão relacionados à necessidade de ampliação do escopo do projeto do sistema de produção, à adaptação dos níveis de planejamento de médio e curto prazo do Sistema Last Planner para este contexto, assim como à necessidade de integração do planejamento e controle do processo de montagem a outros processos à montante da obra. São também propostos diferentes tipos de sistemas de planejamento e controle da produção, em função da complexidade e do tamanho da obra. / In the construction sector, there has been an increase on the use of industrialized building systems, including steel construction systems, due to the contribution of those systems in terms of reducing the duration of projects, and reduction of waste. This change has created opportunities for the application of production management concepts and methods that have been originated in other industries, such as the Lean Production Philosophy, which has brought several benefits for the construction sector, such as waste reduction, increase in productivity and reliability in delivery time. However, there have been only a few research studies on the application of Lean Production concepts on the production planning and control process of companies involved in the delivery of steel construction systems. The aim of this research work is to propose guidelines for the conception and implementation of production planning and control systems for projects delivered by companies that design, manufacture and assemble steel construction systems. Moreover, some adaptations in the Last Planner Systems are proposed for the context of assembling this type of system. Action research was the research strategy adopted in this investigation, which involved the development of five empirical studies in projects carried out by a Brazilian leading company. This investigation started by carrying out an analysis of the material and information flows among the main departments of the company, as well as by assessing the existing planning and control process for site assembly. Then, a set of improvements in that process were devised and implemented in three construction sites of the company. The main results of this research work are concerned with extending the scope of production system design, adapting the medium and short-term planning levels of the Last Planner System to this context, and integrating the planning and control process for site assembly with upstream processes. Moreover, different types of planning and control systems were proposed for different types of projects, according to their complexity and size.

An Analysis of the Proactive Approach as a Potential Tool for Adaptability in Production SystemsDencker, Kerstin January 2011 (has links)
Competitive systems for manufacturing, especially assembly systems, have to cope with frequent changes of external as well as internal demands. A proactive behaviour in an assembly system should make it capable of rapid changes and have an ability to handle frequent changes and disturbances. During recent decades several different system theories have occurred of which the majority remained theories never taken to actual production solutions. The thesis presents results from four case studies. It is suggested, that the proactivity of an assembly system is strongly influenced by the system’s ability to change the three parameters: 1) level of automation, 2) level of information, 3) level of competence[l3] (among the operators in a defined work area). Proactivity is not easy to describe. However, this[l4] thesis has taken a step in that direction. A general definition of proactivity is “taking action by causing change towards a state and not only reacting to change when it happens”. Another way to phrase this is "to be anticipatory and taking charge of situations”. Proactivity can be described as the ability of preparation for: - Changes and disturbance during operation; - Planned long-term evolution for a sustainable and perfect production system. Such a system consists of technical components efficiently integrated with human operators and has the ability to handle frequent changes. Proactivity in an assembly system is dependent on the following factors: - Continuous changes; - Mandate to allocate resources; - Mandate to do short term planning. The thesis presents a first model for evaluation of different technical resources that contributes to an overall proactive system behaviour. The model has been published but not yet tested. / QC 20120119

Green and Circular Capital Investments in Production Industry / Hållbara och Cirkulära Kapitalinvesteringar i ProduktionsindustrinMagnusson, Filip January 2022 (has links)
As the concept of sustainability and environmentalism is growing due to new customer demand and regulations, production industry is facing extreme challenges in rethinking their processes and implement sustainability measures. Several companies are taking reactive measures where changes are made on the shopfloor in form of altered operations. However, preventive measures are lacking in many cases since green production system design is being overlooked due to neglection of environmental improvements in capital investment projects. The objective of this thesis is to explore the current state of environmental sustainability in a production company on its capital investment project level and see how the sustainability work relates to corporate sustainability strategy. Also, the objective is to acquire an understanding of what approaches could be included in the design phase of a capital investment to make it more environmentally sustainable by design. The purpose is to construct a green design process for designing sustainable capital investments, both practically through an interactive case study, and through a conceptual guideline. An interactive case study has been conducted at AstraZeneca in Södertälje, Sweden, to achieve the objective of this thesis. Three other companies have been included for benchmarking, and thus best practice have been acquired. A structured literature review was also conducted with the purpose of acquiring knowledge on what possible lean and green, and circular approaches are suitable for designing capital investment projects. Sustainability is a well implemented concept on corporate level in those companies studied in this thesis. However, in relation to capital investment projects as part of production system design, the concept of sustainability is somewhat lagging, suggesting that the vision on becoming a green organization is recognized on higher managerial level, but not perceived on project level. This thesis provides the reader with a conceptual guideline which guides practitioners in what possible sustainability tools could be used in different stages of capital investment design to enhance circularity. A green design process for how to improve environmental sustainability in capital investment projects was also developed and tested practically at AstraZeneca, Södertälje. Production companies require an organizational cultural change towards a green mindset that allows them to invest in often expensive and resource demanding activities that follows from implementing green processes. Applying an approach of system thinking in capital investments by including green activities that reaches all organizations within the company (such as purchasing, operations, and maintenance) are advised. Production system design is generally neglected in industry and research which can be explained by the lack of structured development processes connected to capital investments. Neglecting production system design is occurring even though it is important because of the high costs and problems in altering production systems in hindsight. / Hållbarhet och ekologism är växande begrepp som på grund av ny kundefterfrågan och nya regelverk ställer produktionsindustrin inför stora utmaningar i att tänka om processer och implementera hållbara affärsmodeller. Flera företag tar reaktiva åtgärder där förändringar görs på fabriksgolvet genom förändrade processer. Däremot saknas i flera fall förebyggande åtgärder då företag ser förbi hållbar design av produktionssystem genom att ignorera möjligheten till hållbara förbättringar i kapitalinvesteringsprojekt. Målet med denna uppsats är att beskriva nuvarande tillämpning av ekologisk hållbarhet i producerande företag på projektnivå i kapitalinvesteringsprojekt för att se hur hållbarhetsarbetet relaterar till hållbara företagsstrategier. Uppsatsen tillhandahåller även kunskap kring vilka hållbara metoder som kan implementeras i designfasen hos kapitalinvesteringsprojekt för att göra dessa mer hållbara från start. Kunskapen har använts för att konstruera en process för systematiskt hållbarhetsarbete för att designa gröna och hållbara kapitalinvesteringar. Både en praktisk och en konceptuell process har konstruerats. För att uppnå målet med uppsatsen har en interaktiv fältstudie genomförts på AstraZeneca i Södertälje, där tre andra producerande företag har inkluderats för att samla kunskap om hur andra företag arbetar med hållbarhet i kapitalinvesteringsprojekt. En litteraturstudie har också utförts med syfte att inhämta kunskap kring vilka cirkulära och gröna leanverktyg som kan användas vid design av kapitalinvesteringsprojekt. Hållbarhet är väl implementerat på organisatorisk nivå i de företag som studerats i denna studie. Däremot faller hållbarhet efter i kapitalinvesteringsprojekt, och därmed design av produktionssystem, vilket tyder på att det finns en vision om att bli ett grönt företag på organisatorisk nivå men som inte syns på projektnivå. Denna uppsats tillhandahåller läsaren med en konceptuell process vilken guidar användaren i vilka möjliga verktyg som kan användas i de olika stegen vid kapitalinvesteringsprojekt. En praktisk process för hur ekologisk hållbarhet kan förbättras i kapitalinvesteringsprojekt har också konstruerats och testats på AstraZeneca i Södertälje. Producerande företag kräver en organisatorisk grön kulturförändring som tillåter dem att investera i ofta dyra och resurskrävande aktiviteter som grundas i implementering av gröna processer. Mer uppmärksamhet bör riktas mot systemtänk i kapitalinvesteringar genom att inkludera gröna aktiviteter som genomsyrar hela organisationen på produktionsnivå, inköpsnivå och underhållsnivå bland andra. Design av produktionssystem ignoreras generellt i industrin och akademin vilket kan förklaras av avsaknaden av strukturerade utvecklingsprocesser kopplade till kapitalinvesteringar. Detta trots vikten av designarbete av produktionssystem då förändringar i systemet i efterhand ofta är både dyrt och problematiskt.

A Framework for Designing a Lean Production System for SMEs, which eases the certification of ISO 9001 & 14001 : A Case Study: CombiQ AB /Padilla, Raul, Pekmezci, Talat January 2011 (has links)
In order to survive in highly competitive local and global markets, it is vital to satisfy the changing demand of the customers. Thus, the importance of competitive factors arises. The companies should provide sufficient amount of products or services on time with the most advantageous prices and best possible quality. Additionally, flexibility is crucial to deal with the change in demand. Therefore, a flexible production system for manufacturers is vastly required. The aim of this Master Thesis is to provide a framework for Small and Medium-sized Enterprises (SMEs) that seek ISO 9001 and 14001 Certifications by proposing a Lean Production System. As a case study, the Swedish company CombiQ AB is investigated regarding its current situation with short and long term goals. Thereby, this framework includes the design of a suitable production system that meets CombiQ’s needs and additionally to that, instructs the company how to build up a Lean Production System. In parallel with ISO Certification requirements, two main Lean Techniques (5S and Kaizen) are explained and exemplified throughout the project. These techniques are straightly linked with the requirements of Quality Management Systems (ISO 9001) and Environmental Management Systems (ISO 14001). As for empirical data, this project is constructed by six interviews within the company and one additional interview with an ISO auditor. As a complement, operational and managerial processes are observed. Additionally, relevant literature is examined, presented and aligned with empirical findings in order to cover the essential concepts of this thesis. The final proposal is the usage of lean thinking as a core philosophy guided by the lean principles and techniques with the ISO requirements in parallel, which are the selected concepts to design a desired production system. Once the design is proposed; as further steps, the company would be able to continue the development process by implementing and starting-up the production. Last but not least; as the major outcome of this Lean Production System framework, the ISO certifications would be accomplished with a higher customer satisfaction and competitiveness.
