Lean production is a systemic approach to meeting customer expectations, whatever they value, by reducing waste. At first glance, lean then could only contribute to sustainability, while sustainability is achieved only if the customer values sustainability. The paper has two objectives. One is to examine whether sustainability is feasible using lean production with sustainability as an added value. The second objective is to examine how current lean construction tools and methods impact the construction and operation of sustainable facilities. The authors also suggest how these lean construction tools and methods have evolved to contribute to green construction. For this study, the authors interviewed lean adopters and conducted literature surveys on lean principles and methods, and its impacts on the economic, social and environmental sustainability.

Materials for modules and payments for your workers are some of the main expenses for the concrete structures with stiffness. In view of this, module construction is one of the essential factors if the project succeeds or not. Traditional module construction that is involved in those activities without adding values results in wastes. This study aimed at adopting a compact method to reduce waste in the module works. The compact module construction model is developed to achieve this goal. Andon of this model is made use of build a spot assurance system. Labours can be assisted immediately in case of any issues are raised. Besides Andon, module processes are introduced to the Kanban system to decrease mold stock and fulfil the flow of process behind ceaseless work. There was one real case discussed to verify if the proposed module applies to all. Application findings indicate that the developed method is able to conduct mandatory banishment in the module flow of the process and add value in the operation.

The Lean Construction philosophy emerged to assist overcome the challenges in optimizing the productive processes of companies. As an effort to quantify the application degree of Lean philosophy in the civil construction companies, several measurement tools were created. In order to discuss the effectiveness of these tools into measuring the presence of the Lean philosophy in construction sites, the present study performed a critical analysis of its methodological procedures, based on four aspects: ‘questionnaires and forms’, ‘answering system’, ‘data collection methodology’, and ‘results’. Although it was not possible to investigate measuring tools from other countries, it was concluded that, among Brazilian methods, the one developed by Pereira (2012) is the most suitable for use since it presented just few problems in its formulation. This way, it is possible to do the intended measurement with assertiveness, substantially contributing to civil construction development.

There is a philosophy in the construction industry to reduce the cost of a project by reducing construction waste and improving productivity. With lower expenses, lean construction emphasizes the cost of the project at a minimum cost. Globally, the philosophy has gained a wide range of popularity in the construction sector. The Lean Construction has helped practitioners with several tools and techniques to implement at different stages of a construction project. Following global trends, this study has investigated lean practices in Pakistan. With the potential advantages experienced by its implementation in Pakistan's construction projects and the level of implementation of various types of tools and techniques has been analyzed. To achieve the goal, the study had tried to capture construction projects in which four shareholders are being represented, which are clients, consultants, contractors and material suppliers. Overall 34 completed questionnaires were collected and then analyzed. The results of the analysis have indicated that pull approach, standard of work, time consuming, visualization tools, the integrated project delivery methods and the quality failure in safe limits are common lean techniques which are being implemented to the local construction industry. While there are major benefits of waste reduction, client satisfaction, better communication, visual control and proper task management to build appropriate work are the key benefits of lean construction.

Abstract The construction industry is plagued by poor project performance and the adoption of lean construction is seen as a way to address this issue. Therefore, this research aims to assess the implementation of lean construction and its relationships with project performance in the Australian construction industry. Just in time, last planner system, Six Sigma, and 5S management are the four lean construction tools investigated in the research. Data were collected using a questionnaire survey from construction practitioners in Sydney, Australia. Results show that the implementation of these four tools is adequate, although some lean activities need to be implemented at a higher level. Lean construction also has strong correlations with many project performance indicators, demonstrating its value to the construction industry that is in a dire need of improvement. Finally, this research also recommends specific areas for improvements.

Full textAbstract:
The Kingdom of Saudi Arabia (KSA) has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made. In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD) is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

The objective of this article is to improve building productivity, evolving from traditional construction to industrial construction. The methodology used here consists of analysing the use of materials, the construction design, the design of the spatial distribution programme, the use of auxiliary means and resources and the application of lean tools in construction. The results achieved here include a complete building system that integrates the design, project and execution, wherein the construction process is improved and inconsistencies in the final project are reduced. With the application of an industrial manufacturing methodology, the productivity in construction is improved, reducing costs, materials, execution times and waste. These productivity improvements result in construction being more sustainable. As a conclusion of the previous analysis, the elements that must be integrated into a complete building project and the need to incorporate industrial manufacturing into construction processes in order to achieve sustainable architecture are established.

Full textAbstract:
The profitability of most construction projects critically depends on construction productivity, which can lead to project cost overruns and schedule delays if not fully addressed. Although a literature review provides numerous worldwide examples of construction productivity improvement by mitigating and eliminating influencing disruptions through lean tool implementation, those studies considered a limited number of productivity disruptions in which the choice of lean tools was not clearly justified. This gap has significantly hampered the required improvements in construction productivity due to the limitations in selecting optimal solutions to fully overcome relevant disruptions and prevent their consequences. Hence, as a response to the aforementioned shortcomings, the present study develops the lean-Clancy-based decision-making matrix (LCDMM) that combines two different methods—the “Clancey heuristic model” and “lean construction”—with the goal of determining optimal and beneficial solutions to eliminate disruptions. The main thrust towards the adaptation of the matrix is based on its potential to link disruptions with solutions based on lean tools. In order to assess the practicality of LCDMM, the proposed solutions for two disruptions, as examples, are compared to existing practical solutions. Ultimately, it is clear that LCDMM, as a reusable tool, can assist scholars and practitioners in assembling the analysis of disruption waste and in selecting solutions for productivity improvement.

Abstract: Since the 1940’s, lean production principles have evolved and were successfully implemented by Toyota Motor Company. Lean construction is a production and management-based approach to a project. An increasing number of construction academics and professionals are storming the ramparts of conventional construction management in an attempt to deliver better value to owners while making real profits. As a result, lean-based tools have emerged and are successfully applied to simple and sophisticated construction projects. Generally, lean construction projects are easier to manage, safer, completed sooner, cost less and are of higher quality. Thanks to the success of the lean production system in manufacturing the construction industry has adapted lean techniques to eliminate waste and increase profit. It is a way to design production system to minimize the wastage of material, time, and effort in order to generate the maximum possible amount of value. The main objective of this study is to analyze and implement the lean construction practices. Keywords: lean construction, economic, safe, construction management

The development of more effective management techniques has become essential for the improvement of working conditions within the company. The construction industry is characterized by unpredictable and fluctuating construction processes which increase the level of risk of accidents. In this context, this work aims at conducting a synthesis of the most reliable research in the field of safety management in order to study the contribution of Lean Construction practices in the promotion of safety. The study evaluates the potential effectiveness of Lean Construction tools such as (Last Planner System, Visual Management, 5S, Error-proofing) in promoting the safety on construction sites. This study shows that lean construction tools have a great potential to improve the safety performance. Several Lean Construction practices such as the correlation between scheduled tasks and the ability of the staff working on site, choosing of working methods in compliance with safety requirements, the incorporation of visual tools, and the Simplification of workflow could minimize the risk of accidents and promote the worker safety through minimizing hazards, motivating people involvement in the planning phase and preventing human errors.

The poor safety situation in the United Kingdom (UK) construction industry and its adverse socio-economic record are well documented in the existing literature. The application of Lean Construction techniques has been proposed as an effective strategy to address accidents on construction sites, a major safety concern in the construction industry. However, examination of the relationship between Lean Construction techniques and safety issues has been marginal. This study explores this relationship with the aim of developing a framework for using Lean Construction techniques to promote safety on UK construction sites. A framework was initially devised based on a synthesis of the literature and further refined based on findings from interviews held with 10 Lean Construction practitioners on antecedents of Lean Construction techniques and safety issues. In order to develop and confirm the framework, data was collected from practicing Lean Construction organisations using a questionnaire survey and analysed using descriptive statistics, inferential statistics and inter-rater agreement statistical test to examine the pattern and extent of the relationships. The study found a total of thirty-eight (38) relationships between Lean Construction techniques and safety issues. These relationships are mainly positive in nature in that they demonstrate path to improvement in safety on construction sites. They show which techniques could be used to address the relevant safety issue. Furthermore, it was established that the application of Lean Construction techniques on construction sites can be impeded by challenges such as: lack of Lean Construction knowledge, complexity, misconception about Lean and difficulties in changing employees’ working culture. The study identified strategies that could be used to address these challenges. These include enlightenment on benefits of Lean practice, publication of improvements realised from Lean practice, training, workers’ involvement and empowerment, persistence, robust planning and gradual step-by-step implementation. The study, therefore, concludes that Lean Construction techniques have positive relationships with safety issues on construction sites in the UK and on the basis of the relationships develops an integrated framework to guide application of the techniques by contracting organisations in promoting safety. The study makes a number of recommendations including the incorporation of Lean Construction practice into government health and safety initiatives, regulations and policies, and identifies areas for further research.

Full textAbstract:
The Kingdom of Saudi Arabia construction industry is bedevilled with many problems. Many construction projects delivered to poor cost, time, quality performances. In addition, many of the construction organisations in the KSA operate with inefficient project delivery processes and produce enormous wastes and low-value return to clients. Lean construction has been proposed as a management strategy for overcoming the problems associated with construction project delivery and organisational processes in the KSA construction industry. Despite the avalanche of frameworks for implementing lean construction strategies, the appropriate framework for promoting lean construction in the KSA construction industry is lacking. The result is the limited implementation of lean construction in the KSA construction industry. Beside the lack of an appropriate framework for implementing lean construction strategies, there is a concerning dearth of research addressing issues pertaining to the implementation of lean construction such as the barriers and critical success factors (CSFs) for implementing lean construction in the KSA construction industry. As a result, the state of art of lean construction in the KSA construction industry is unknown. Therefore, this study is carried out to promote lean construction in the KSA construction industry.
The research methodology follows a pragmatic research paradigm which allows the combined use of quantitative and qualitative research methodologies. The quantitative methodology aspects involve the questionnaire survey of experts to obtain their opinion on the types of wastes, the tools and techniques that support the implementation of lean construction, benefits of lean construction, and stages of application of lean methods in the KSA construction industry. In addition, the questionnaire was used to gather experts' opinion about the barriers to the implementation of lean construction in the KSA construction industry. The data obtained from the survey was analysed using powerful statistical analysis techniques such as one-way ANOVA, and the exploratory and confirmatory factor analysis. An open-ended questionnaire combined with an interview scheme was also designed to obtain the experts' views on the CSFs for implementing lean construction in the KSA construction industry. The data obtained was qualitatively analysed using content analysis to derive a comprehensive list of CSFs for implementing lean construction in the KSA construction industry. On the basis of the list derived, selected experts were asked to complete a pairwise comparison of the CSFs through a well-designed row and column questionnaire. An ISM technique was employed to specify the interrelationships among the CSFs, as well as their hierarchies in order to develop an ISM model for promoting lean construction in the KSA construction industry. An interview with experts who have the understanding of lean construction and the operations of the KSA construction industry was carried out to check for conceptual inconsistencies, and to confirmif the model can be implemented as a lean construction framework for improving the performance of construction projects and organisations in the KSA construction industry.
The investigation reveals that 'waiting' is the most pervasive type of waste in the KSA construction industry, while the level of pervasiveness of the over-processing and over-production types of wastes are different between the large and small construction companies mainly due to resource constraints. There are a myriad number of different tools/techniques that support the implementation of lean construction in the KSA construction industry, but the computer aided design (CAD) provides the most support to the implementation of lean construction. The top ranked barriers which are of greatest concern to the implementation of LC in the KSA construction industry are: influence of traditional practices, unfavorable organisational culture, lack of technical skills about lean techniques, and lack of understanding of lean approaches. In descending order of pervasiveness, the principal factors that constitute these barriers in the KSA construction industry are the traditional practices barrier, client-related barrier, standardisation barrier, a technological barrier, performance and knowledge barrier, and cost related barrier. Of these principal barriers, the client related barrier is a new kind of barrier to implementing lean construction in the body of knowledge.
There are 12 CSFs for implementing lean construction in the KSA construction industry. As a result, an ISM model that specifies the relationship between the CSFs for implementing lean construction in the KSA construction industry is developed, while a further validation study confirms that the ISM model can be implemented as a lean construction framework for improving the performance of construction projects and organisations in the KSA construction industry. The ISM model comprises of 7 hierarchies (VII-I) of the 12 CSFs. The CSFs in the top hierarchy are the most important CSFs for implementing lean construction in the KSA construction industry. Those in the middling hierarchy are very unstable, whereby any action taken on one or more of them has an effect on another. Therefore, utmost care and consideration are necessary when putting in place any of these CSFs for the implementation of lean construction in the KSA construction industry. The CSF in the least hierarchy is the least important in the KSA construction industry, and to apply this CSF is entirely reliant on the other CSFs, in other words, other CSFs need to be in place to apply this CSF to the implementation of lean construction in the KSA construction industry.
Overall, the study generates a new knowledge in the area of lean construction in the KSA construction industry context. This study reveals the state of art of lean construction in the KSA construction industry. In addition, this study identifies the barriers to, and the CSF for implementing lean construction in the KSA construction industry. This study also develops an ISM model that specifies the relationship among the CSFs for implementing lean construction towards the development of a framework for promoting lean construction in the KSA construction industry. In contrast to existing frameworks, the framework reflects the socio-cultural and operation context in the KSA construction industry.

Målet med denna studie är att hjälpa fallföretaget med att minska materialhanteringen på avdelningen internlogistik, som bland annat innefattar godsmottagning och lagerhantering. Detta kommer att göras genom framtagning av en ny anläggningslayout. Genom automatisering av utlastningen och den nya layouten reduceras och/eller elimineras slöserier i form av transport, tid, etc. samtidigt som ett effektivare flöde skapas internt på företaget. För att kunna genomföra denna studien har kvalitativa och kvantitativa metoder använts vid datainsamlingen för att säkerställa att studien erhåller en hög vetenskaplig trovärdighet. Bakgrunden till att studien genomfördes är för att det blivit en svårighet för växande industriföretag att kunna hantera materialhanteringen på grund av för mycket arbete och kunna ha en effektiv internlogistik. Detta i sin tur ligger i grund för företag att kunna uppnå hög utnyttjandegrad, effektivt flöde och en välplanerad internlogistik för att kunna bli starkare gentemot konkurrenterna.

I Sverige har bostadsbristen lagt ytterligare fokus på att bygga billigare och snabbare. Byggbranschen har konstanta krav på sig att bygga effektivare och samtidigt upprätthålla sin kvalitet. Branschen utvecklas hela tiden och många företag har skapat egna verktyg och metoder för att förbättra sin effektivitet samt kvalité. Ursprungsidéerna kommer från Toyotas produktionsidéer från 1900-talet. Därifrån har teorier om kvalitetstänk och effektivitet blivit populärt att implementera och begreppet har t ex utvecklats att inom byggbranschen kallas för Lean Contruction. Då det finns mycket teori inom området ansåg författaren att ämnet skulle vara relevant att undersöka samt hur Lean Construction fungerar i verkligheten. Därför är syftet med denna studie att undersöka om byggföretag skulle kunna tillämpa vissa verktyg och metoder som finns inom Lean Construction. Skulle dessa verktyg och metoder kunna generera mer effektivitet i byggföretagens dagliga arbete. För att kunna genomföra denna studie har frågeformulär skickats ut till tre olika byggföretag. I frågeformuläret fick respondenterna rangordna de olika verktyg och metoder som de ansåg hade effektivitet samt de som inte hade någon effektivitet. Där fick de svara på vilka verktyg och metoder inom Lean Construction som de trodde skulle kunna förbättra sin effektivitet och om de redan själva arbetade efter någon metod som skulle höja deras effektivitet. De flesta av respondenterna visste vad Lean Construction är för något, men alla hade inte använt sig av det. Mellan de olika företagen skiljde det sig på vad de ansåg var effektivt arbete och ej. För att fastställa uppsatsens metod har en bred undersökningsstudie gällande metoder gjorts, de olika metoderna har avvägts mellan varandra för att undersöka vilken som skulle komplettera insamlad data. Genom att använda sig av frågeformulär och insamlad teori, valdes en kvalitativ metod. Fördelen med detta val av metod är att författaren kan jämföra insamlad data med teorin. Författaren valde att endast använda sig av tre olika byggföretag då studien inte skulle bli generaliserande utan få en mer öppen och tolkande bild av hur det ser ut i byggbranschen. För att kunna besvara syftet har författarens gjort begränsningar, detta genom att endast fokusera på de verktyg och metoder som finns inom Lean som skulle kunna bidra till en högre effektivitet hos byggföretag. Utifrån respondenternas svar framkom att metoder inom 5S kan tillämpas inom byggbranschen. Den insamlade teorin och den empiriska datan analyserades och ledde fram till slutsatsen. Studiens slutsats visar på att 5S metoden är den metod som lättast kan tillämpas inom byggbranschen. Respondenterna ansåg att några av de metoderna inom 5S redan arbetades efter dagligen.In Sweden housing has been given further focus to build cheaper and faster. Construction have constant requirements to build more effective and at the same time maintain their quality. The industry evolves all the time and many businesses have created own tools and methods to keep improving the efficiency and quality of their work. The original ideas came from Toyotas production ideas from the early 1900. The theories about quality thinking and efficiency have been popular to implement and the concept has for example developed within construction and is called Lean Construction. Since there is a lot of theory within the field the writer felt that the subject should be relevant to examine and see how Lean Construction is working in reality. Therefore, the aim of this study is to investigate if the construction firm should be able to implement some tools and methods that you can find within Lean Construction. Would these tools and methods be able to generate more efficiency in the construction firm’s daily work. To be able to implement this study, a questionnaire has been sent out to 3 different construction firms. In the questionnaire the respondents rank the different tools and methods they thought had efficiency and the one’s that didn’t have any efficiency. Where they answered which tools and methods within Lean construction that they thought would improve the efficiency and if they already have worked by a method that should rise the efficiency. Most of the respondents have heard of the Lean Construction before but not everyone had used it. Between the different construction firm’s opinions about what kind of methods about efficiency varied. A wide study of different methods was made to determine what kind of methods should be used when writing this essay, the different methods have been balanced between each other to determine which should complete the collected data. By using the questionnaire and collected theory, a qualitative method was selected. The benefit with this method was that the writer could compare the collected data with the theory. The writer chose only 3 construction firms so that the study shouldn’t be generalized but instead be more open for interpretive picture of how the work within construction looks like. To be able to answer the purpose, the writer set some limitations, by only focusing on the tools and methods within Lean that should contribute to a higher efficiency at the construction firm. Through the respondents answer it emerged that methods within 5S can be applied within construction. The collected theory and the empirical data were analyzed and led to the conclusion. The study showed that the 5s method is the easiest method to implement at the construction firm. Respondents meant that some of the methods within 5S already is applied in their daily work.

The use of tools to analyze the implementation and use of practices and principles of lean construction is extremely necessary for them to be successful and bring the expected results. Therefore, the tool which is going to be used must be adequate and capable of measuring in the best possible way the real state of the construction company against lean philosophy. This research's objective is to develop a tool to evaluate the degree of implementation of the lean construction in building companies. The LCAT (Lean Construction Assessment Tool) has been developed based on other tools previously proposed with the aim of supply the deficiencies presented by them, mainly the absence of statistical treatment and in the fidelity of the results. Using multivariate data analysis techniques, such as hierarchical group analysis, form revisions were performed, which, according to the comparative tests executed, increased their level of replication and applicability. The evaluation form was analyzed by experts, who classified the items as their importance, complexity and time of implementation. The Fuzzy Inference System was utilized in order to reduce the subjectivity and interpretation bias of the evaluator, which generated closer results between two different applicators to the same object of study. As a secondary result, the participating companies of the applications were evaluated towards the implementation of the lean construction. It was noticed that the companies, for the most part, still do not apply lean construction concepts and tools, evidences were found only of the application practices that interfaced with other areas of management, such as quality and planning.
O uso de ferramentas para a análise da implementação e uso de práticas e princípios da construção enxuta é extremamente necessário para que estas sejam bem-sucedidas e tragam os resultados esperados. Para isso, a ferramenta a ser utilizada deve ser adequada e capaz de aferir da melhor maneira possível o real estado da empresa construtora frente à filosofia enxuta. O objetivo desse trabalho é desenvolver uma ferramenta de avaliação do grau de implementação da construção enxuta em empresas construtoras. A LCAT (Lean Construction Assessment Tool) foi desenvolvida com base em outras ferramentas anteriormente propostas com o intuito de suprir as carências por elas apresentadas, principalmente no tratamento estatístico e na fidelidade dos resultados. Utilizando-se de análise multivariada de dados, foram feitas duas grandes revisões no formulário, que, de acordo com testes comparativos realizados, aumentaram seu nível de replicação e aplicabilidade. Como resultado secundário, avaliou-se as empresas participantes das aplicações frente à implementação da construção enxuta.

Full textAbstract:
Purpose – The purpose of this study is to increase the knowledge about the material handling of a module house manufacturing company. In order to achieve the study's purpose, three research questions were formulated. ▪ Which factors affect material handling? ▪ Which factors are considered important for material handling? ▪ How can standardization improve material handling? Method – The study has been characterized by an inductive approach to conducting the case study. To achieve the purpose, empirical data has been collected via a pilot study, interviews, observations, and document studies from reality. Subsequently, previous theories were examined via a literature collection. Furthermore, the processing and analysis of collected empirics and theory have helped to answer the purpose and demonstrate the generalizability of the study. Findings – The study has focused on the entirety of the various processes and an understanding of the various factors that influence material handling has been obtained. The case study company has challenges to look at the entirety of the modular house production and separates the production and construction sites. The wastes transport, movement, waiting and unused skills are considered to be the most important wastes to reduce or eliminate. It is clear that the case study company’s new employees must constantly reinvent the wheel and learn from their own mistakes. Moreover, it is difficult to determine if the mistake is a deviation, error or insufficient knowledge. By implementing a standard for what should be on drawings and how materials are to be delivered from production to the construction sites, deviations and wastes can be reduced and costs reduced. Implications – The study is based on a problem area that already exists in separate theories and comparisons. However, operations that have a material handling that both concerns manufacturing and construction work have not previously been investigated to the same extent, which is the theoretical contribution of the study. The empirical contribution to the study is to identify which factors affect material handling in businesses that have common flows between manufacturing and construction work. Limitations – The study only addresses two of the material handling flows; the material flow and the information flow. The study also does not take into account the processes of suppliers, subcontractors, or customers. Finally, the study will not include financial calculations to demonstrate potential cost efficiencies. Keywords – Material handling, Lean, Construction logistics, Wastes, Current flow, Value stream mapping, Lean tools.

In the current globalized world, the market is characterized by the high competitiveness, easy access to information and high consumer demand. The analysis of the impacts of lean office application to the supply unit on a construction company is very relevant, considering that companies focused on the civil construction area depend for consolidation of their businesses, efficient management strategies and suppliers of materials and services, external to their organization. The use of lean office as a management tool in the purchasing department of construction companies offers a competitive advantage amid the current market situation. Thereby, this study seeks to clearly conceptualize the lean philosophy and its tools as well as the management of the information systems and also the management of the supply chain, among other aspects. One construction company was then selected for the design research. This company contributes with information for the accomplishment of this work. The method used in this dissertation consists in describing the company, drawing the preliminary map of the supply unit, from this, it was possible to draw up the value stream map in the present state. With this map it could be analyzed and proposing improvements in the production process and then, designed a value stream map in the future state, applying these enhancements. The results led to the identification of flaws and possible opportunities for management improvements in the company.
No atual contexto globalizado o mercado é caracterizado pela alta competitividade, fácil acesso às informações e elevada exigência do consumidor. A análise dos impactos da aplicação do lean office na unidade de suprimentos de uma construtora, é de alta relevância, visto que empresas voltadas à área da construção civil dependem, para consolidação dos seus empreendimentos, de estratégias de gestão eficientes e de fornecedores de materiais e serviços externos à sua organização. Sendo assim, a utilização do lean office, como ferramenta gerencial na unidade de compras, oferece às empresas construtoras uma vantagem competitiva em meio à presente situação do mercado. O presente trabalho procurou conceituar a filosofia enxuta e suas ferramentas, o gerenciamento dos sistemas de informação e a gestão do setor de suprimentos, entre outros aspectos. A partir destes, buscou-se uma empresa construtora para realizar uma pesquisa-ação. Esta construtora contribuiu com informações necessárias para realizar esta dissertação. O método utilizado nesta dissertação consiste em descrever a empresa, desenhar o mapa preliminar da unidade de suprimentos e a partir deste elaborar o mapa de fluxo de valor presente para a unidade, analisando-o e propondo melhorias em seu processo de produção. Em seguida criar um mapa de fluxo de valor no estado futuro, aplicando estes aprimoramentos. Os resultados levaram à identificação das falhas e das possíveis oportunidades de melhorias de gestão na empresa estudada.

Full textAbstract:
This book not only discusses cellular automata (CA) as accouterment for simulation, but also the actual building of devices within cellular automata. CA are widely used tools for simulation in physics, ecology, mathematics, and other fields. But they are also digital "toy universes" worthy of study in their own right, with their own laws of physics and behavior. In studying CA for their own sake, we must look at constructive methods, that is the practice of actually building devices in a given CA that store and process in formation, replicate, and propagate themselves, and interact with other devices in complex ways. By building such machines, we learn what the CA's dynamics are capable of, and build an intuition about how to "engineer" the machine we want. We can also address fundamental questions, such as whether universal computation or even "living" things that reproduce and evolve can exist in the CA's digital world, and perhaps, how these things came to be in out own universe.

Full textAbstract:
Gamers have been in trouble as long as games have existed, constantly mired in controversies about violence, diversity, and online harassment. As our popular understanding of “gamer” shifts beyond its historical construction as a white, straight, adolescent, cisgender male, the troubles that emerge both confirm and challenge our understanding of identity politics. This book excavates the turbulent relationships between surface and depth in contemporary gaming culture, taking readers under the hood of the mechanisms of video games in order to understand the ways that gender, race, and sexuality operate in their technological, ludic, ideological, and social systems. By centering the insights of queer and women of color feminisms in readings of online harassment campaigns, industry animation practices, and popular video games like Portal, Bayonetta, Tomb Raider, and Mass Effect, Phillips adds necessary analytical tools to our conversations about video games. In the context of a political landscape in which reinvigorated forms of racism, sexism, and homophobia thrive in games and gaming communities, Phillips follows the lead of those who have been making good trouble all along, agitating for a better world.

Full textAbstract:
In a large room, on the third floor of an old woollen mill in the South West of England, nine architects spend most of their working lives, designing buildings and overseeing their construction. Asked where these come from, architects admit a kind of ignorance: 'Total magic!' as one puts it, 'Something comes from nothing!' Focusing on the everyday lives of architects, the book explores how buildings are assembled through an intimate and elusive choreography of people, materials, places, tools and ideas. Through these interactions, it asks and answers some questions of wider interest: What is the relationship between a working and a personal life? What is creativity? How is it possible to live truthfully in a world of contradiction and compromise? What does it mean to claim to know with authority? Most basically but most fundamentally the book is concerned with the question of what it is like to be an architect, and what lessons others might learn from the example their experience provides. Amongst other things, these have to do with the nature of expert knowledge, design, creativity and the central but less celebrated arts of administration.

Full textAbstract:
The college classroom is a place where students have the opportunity to be transformed and inspired through learning—but teachers need to understand how students actually learn. This book provides an accessible, hands-on guide to the craft of college teaching, giving instructors the practical tools they need to help students achieve not only academic success but also meaningful learning to last a lifetime. The book explains what to teach—emphasizing concepts and their relationships, not just isolated facts—as well as how to teach using active learning strategies that engage students through problems, case studies and scenarios, and practice reinforced by constructive feedback. The book tells how to motivate students, run productive discussions, create engaging lectures, use technology effectively, and much more. Interludes between chapters illustrate common challenges, including what to do on the first and last days of class and how to deal with student embarrassment, manage group work, and mentor students effectively. There are also plenty of questions and activities at the end of each chapter. This book is an essential resource for new instructors and seasoned pros alike.

Full textAbstract:
Why do some teams thrive, while others struggle? If you are a team leader, team member, senior leader, or consultant, you need to know what really drives team effectiveness. Many books and consultants offer advice about teamwork based on opinion or conjecture. Some of that advice is useful, but much of it is overly simplistic or even misleading. Fortunately, a growing body of research is now available with which to separate the myths from the facts. For example, is it possible to “team away” talent deficiencies? Will more frequent communications improve performance? Is a team likely to perform better when members know each other? What do great team members know, do, and think? When and how can conflict be constructive? In Teams That Work, Scott Tannenbaum and Eduardo Salas answer these and other questions about team effectiveness. While reading the book you’ll learn: Eleven desirable team member competencies and three traits you’ll want to avoid; Four cooperative beliefs that consistently impact team effectiveness; Four coordination behaviors that you’ll want your teams to demonstrate; Eight types of shared cognitions team members need to possess; A dozen conditions that enable collaboration; and seven essential team leadership functions. The book culminates with specific, evidence-based tips along with tangible tools for putting the science of teamwork into practice.

Full textAbstract:
The case study developed as part of IIEP‐UNESCO Research Project ‘Open Government: Learning From Experience’ analyses how an open government approach is being applied in Ukraine to resolve the critical issue of non‐transparent school financing through parents’ donations that undermines trust among key educational stakeholders. Developed in 2016, the Open School Platform (OS) is an online tool that allows parents to visualise the school’s budget, needs and expenditures in an easy‐ to‐read format. The study shows that OS has contributed to: improved trust among key stakeholders, improved communication and collaboration between school personnel and local public authorities, and more effective planning. But it also confirms that the use of ICT can lead to inequalities in poor rural communities having low levels of Internet access or computer literacy. It concludes on the importance of open government for shifting to a new paradigm of cooperation and partnership. And it recommends providing access to information in line with the Open Data Charter; ensuring a legal framework for citizen participation; using handy and accessible technological solutions; and following a ‘learning‐by‐doing’ approach to build up social capital for constructive interaction with authorities.

Full textAbstract:
Abstract The use of formal modelling and computational simulation in studies of the Roman economy has become more common over the last decade. But detailed critical evaluations of this innovative approach are still missing and much needed. What kinds of insights about the Roman economy can it lead to that could not have been obtained through more established approaches, and how do simulation methods constructively enhance research processes in Roman Studies? This edited volume addresses this need through critical discussion and convincing examples. It presents the Roman economy as a highly complex system, traditionally studied through critical examinations of material and textual sources, and understood through a wealth of diverging theories. A key contribution of simulation lies in its ability to formally represent diverse theories of Roman economic phenomena and test them against empirical evidence. Critical simulation studies rely on collaboration across specialisms in Roman data, theory, and method, and can constructively enhance multivocality of theoretical debates of the Roman economy. This potential is illustrated, avoiding computational and mathematical language, through simulation studies of a wealth of Roman economic phenomena: from maritime trade and terrestrial transport infrastructures, through the economic impacts of the Antonine Plague and demography, to local cult economies and grain trade. Through these examples and discussions, this volume aims to provide the common ground, guidance, and inspiration needed to make simulation methods part of the tools of the trade in Roman Studies, and to allow them to make constructive contributions to our understanding of the Roman economy.

AbstractTheories and tools based on multiparty session types offer correctness guarantees for concurrent programs that communicate using message-passing. These guarantees usually come at the cost of an intrinsically top-down approach, which requires the communication behaviour of the entire program to be specified as a global type.This paper introduces : an OCaml library that supports the development of correct message-passing programs without having to write any types. The library utilises the meta-programming facilities of OCaml to automatically infer the session types of concurrent programs and verify their compatibility (k-MC [15]). Well-typed programs, written with , do not lead to communication errors and cannot get stuck.

We discuss the design rationale behind the optimization problem and establish that the computed output is probably approximately correct. Our experimental evaluations over a variety of systems show promise. can learn accurate reachability functions for complex nonlinear systems, including some that are beyond existing methods.

Abstract The Debian distribution includes more than 28 thousand maintainer scripts, almost all of them are written in Posix shell. These scripts are executed with root privileges at installation, update, and removal of a package, which make them critical for system maintenance. While Debian policy provides guidance for package maintainers producing the scripts, few tools exist to check the compliance of a script to it. We report on the application of a formal verification approach based on symbolic execution to find violations of some non-trivial properties required by Debian policy in maintainer scripts. We present our methodology and give an overview of our toolchain. We obtained promising results: our toolchain is effective in analysing a large set of Debian maintainer scripts and it pointed out over 150 policy violations that lead to reports (more than half already fixed) on the Debian Bug Tracking system.

Full textAbstract:
AbstractWe introduce a similarity function on formulae of signal temporal logic (STL). It comes in the form of a kernel function, well known in machine learning as a conceptually and computationally efficient tool. The corresponding kernel trick allows us to circumvent the complicated process of feature extraction, i.e. the (typically manual) effort to identify the decisive properties of formulae so that learning can be applied. We demonstrate this consequence and its advantages on the task of predicting (quantitative) satisfaction of STL formulae on stochastic processes: Using our kernel and the kernel trick, we learn (i) computationally efficiently (ii) a practically precise predictor of satisfaction, (iii) avoiding the difficult task of finding a way to explicitly turn formulae into vectors of numbers in a sensible way. We back the high precision we have achieved in the experiments by a theoretically sound PAC guarantee, ensuring our procedure efficiently delivers a close-to-optimal predictor.

Full textAbstract:
AbstractRegression testing is an important activity to check software changes by running the tests in a test suite to inform the developers whether the changes lead to test failures. Regression test prioritization (RTP) aims to inform the developers faster by ordering the test suite so that tests likely to fail are run earlier. Many RTP techniques have been proposed and are often compared with the random RTP baseline by sampling some of the n! different test-suite orders for a test suite with n tests. However, there is no theoretical analysis of random RTP. We present such an analysis, deriving probability mass functions and expected values for metrics and scenarios commonly used in RTP research. Using our analysis, we revisit some of the most highly cited RTP papers and find that some presented results may be due to insufficient sampling. Future RTP research can leverage our analysis and need not use random sampling but can use our simple formulas or algorithms to more precisely compare with random RTP.

Full textAbstract:
In this report, we demonstrate how an interdisciplinary team of computer science and learning sciences researchers utilize an adapted conjecture mapping tool during a collaborative problem-solving session. The session is documented through an edited “Dialogue” format, which captures the process of conjecture map construction and subsequent reflection. We find that creating the conjecture map collaboratively surfaces a key tension: while learning sciences theory often highlights the nuanced and complex relational nature of learning, even the most cutting-edge computing techniques struggle to discern these nuances. Articulating this tension proved to be highly generative, enabling the researchers to discuss how considering impacted community members as a critical “part of the solution” may lead to a socio-technical tool which supports desired learning outcomes, despite limitations in learning theory and technical capability. Ultimately, the process of developing the conjecture map directed researchers towards a precise discussion about how they would need to engage impacted community members (e.g., teachers) in a co-design process.

Current methods for producing all-male fingerlings, including hormone treatments and genetic manipulations, are not entirely reliable, in part because of the genetic complexity of sex determination and sexual differentiation in tilapias. The goals of this project are to map QTL and identify genes regulating sex determination in commonly cultured tilapia species, in order to provide a rational basis for designing reliable genetic approaches for producing all-male fingerlings. The original objectives for this research were: 1) to identify the gene underlying the QTL on LG1 through positional cloning and gene expression analysis; 2) to fine map the QTL on LG 3 and 23; and 3) to characterize the patterns of dominance and epistasis among QTL alleles influencing sex determination. The brain aromatase gene Cyp19b, a possible candidate for the genetic or environmental SD, was mapped to LG7 using our F2 mapping population. This region has not been identified before as affecting SD in tilapias. The QTL affecting SD on LG 1 and 23 have been fine-mapped down to 1 and 4 cM, respectively, but the key regulators for SD have not been found yet. Nevertheless, a very strong association with gender was found on LG23 for marker UNH898. Allele 276 was found almost exclusively in males, and we hypothesized that this allele is a male-associated allele (MAA). Mating of males homozygous for MAA with normal females is underway for production of all-male populations. The first progeny reaching size allowing accurate sexing had 43 males and no females. During the course of the project it became apparent that in order to achieve those objectives there is a need to develop genomic infrastructures that were lacking. Efforts have been devoted to the development of genomic resources: a database consisting of nearly 117k ESTs representing 16 tissues from tilapia were obtained; a web tool based on the RepeatMasker software was designed to assist tilapia genomics; collaboration has been established with a sequencing company to sequence the tilapia genome; steps have been taken toward constructing a microarray to enable comparative analysis of the entire transcriptome that is required in order to detect genes that are differentially expressed between genders in early developmental stages. Genomic resources developed will be invaluable for studies of cichlid physiology, evolution and development, and will hopefully lead to identification of the key regulators of SD. Thus, they will have both scientific and agricultural implications in the coming years.

Project objectives: 1) Characterization of variation for yield heterosis in melon using Half-Diallele (HDA) design. 2) Development and implementation of image-based yield phenotyping in melon. 3) Characterization of genetic, epigenetic and transcriptional variation across 25 founder lines and selected hybrids. The epigentic part of this objective was modified during the course of the project: instead of characterization of chromatin structure in a single melon line through genome-wide mapping of nucleosomes using MNase-seq approach, we took advantage of rapid advancements in single-molecule sequencing and shifted the focus to Nanoporelong-read sequencing of all 25 founder lines. This analysis provides invaluable information on genome-wide structural variation across our diversity 4) Integrated analyses and development of prediction models Agricultural heterosis relates to hybrids that outperform their inbred parents for yield. First generation (F1) hybrids are produced in many crop species and it is estimated that heterosis increases yield by 15-30% globally. Melon (Cucumismelo) is an economically important species of The Cucurbitaceae family and is among the most important fleshy fruits for fresh consumption Worldwide. The major goal of this project was to explore the patterns and magnitude of yield heterosis in melon and link it to whole genome sequence variation. A core subset of 25 diverse lines was selected from the Newe-Yaar melon diversity panel for whole-genome re-sequencing (WGS) and test-crosses, to produce structured half-diallele design of 300 F1 hybrids (MelHDA25). Yield variation was measured in replicated yield trials at the whole-plant and at the rootstock levels (through a common-scion grafted experiments), across the F1s and parental lines. As part of this project we also developed an algorithmic pipeline for detection and yield estimation of melons from aerial-images, towards future implementation of such high throughput, cost-effective method for remote yield evaluation in open-field melons. We found extensive, highly heritable root-derived yield variation across the diallele population that was characterized by prominent best-parent heterosis (BPH), where hybrids rootstocks outperformed their parents by 38% and 56 % under optimal irrigation and drought- stress, respectively. Through integration of the genotypic data (~4,000,000 SNPs) and yield analyses we show that root-derived hybrids yield is independent of parental genetic distance. However, we mapped novel root-derived yield QTLs through genome-wide association (GWA) analysis and a multi-QTLs model explained more than 45% of the hybrids yield variation, providing a potential route for marker-assisted hybrid rootstock breeding. Four selected hybrid rootstocks are further studied under multiple scion varieties and their validated positive effect on yield performance is now leading to ongoing evaluation of their commercial potential. On the genomic level, this project resulted in 3 layers of data: 1) whole-genome short-read Illumina sequencing (30X) of the 25 founder lines provided us with 25 genome alignments and high-density melon HapMap that is already shown to be an effective resource for QTL annotation and candidate gene analysis in melon. 2) fast advancements in long-read single-molecule sequencing allowed us to shift focus towards this technology and generate ~50X Nanoporesequencing of the 25 founders which in combination with the short-read data now enable de novo assembly of the 25 genomes that will soon lead to construction of the first melon pan-genome. 3) Transcriptomic (3' RNA-Seq) analysis of several selected hybrids and their parents provide preliminary information on differentially expressed genes that can be further used to explain the root-derived yield variation. Taken together, this project expanded our view on yield heterosis in melon with novel specific insights on root-derived yield heterosis. To our knowledge, thus far this is the largest systematic genetic analysis of rootstock effects on yield heterosis in cucurbits or any other crop plant, and our results are now translated into potential breeding applications. The genomic resources that were developed as part of this project are putting melon in the forefront of genomic research and will continue to be useful tool for the cucurbits community in years to come.
