Abstract:
The paper examines the current state of Production Planning and Control (PPC), identifies some technical and systems changes that have occurred over recent years and links these with the requirements being placed on companies by the market. PPC is being asked to respond effectively to these internal and external changes by being more dynamic and providing better control of resources and delivery performance. Some of the requirements to be satisfied by the new PPC systems are identified. To meet these requirements it is suggested that better understanding is required of how different factors affect PPC systems performance and that administrative systems need improving. The quantitative, administrative and behavioural aspects of PPC are discussed. A framework for developing an agenda for action and research is provided.

Abstract:
Dynamic and unforeseeable characteristic of the current market and production environment is not feasible to be met through pre-set parameters being dependent on the predictions. Handling this matter requires to keep focus on production system adaptability. Evolvable Production System has achieved fully system reconfigurability through process oriented modularity and multi agent based distributed control system architecture. One of the essential enhancements provided by EPS on the shop floor is achieving minimized/eliminated system setup time in response to changing product requirements. Manufacturing planning and control system, on the other hand, follows hierarchical principles which are quite much reliant on the predicted information so to structure production and planning environment on it. Production system limitations, such as lack of adaptability in response to changing conditions, are in fact influencing the planning system to be structured on the predictions. The enhancements which are ensured by the architecture of EPS enable to relax the constraints on planning system which are imposed by the limitations of production system. These enhancements have an effect at different levels in the planning hierarchy. On the light of these improvements, the planning framework as it is used so far in the industry becomes invalid and this arise a requirement for planning system structure to be designed according to a fully reconfigurable system to be able to benefit such a production system by all means. This thesis targets to enlighten the relation between the production system characteristics and planning system structure by emphasizing the planning problems and proposing a planning reference architecture solution to be able achieve a responsive planning framework.

Abstract:
A industrialização da construção civil é uma das possíveis estratégias adotadas para melhorar a qualidade e produtividade da produção neste ambiente altamente competitivo. Entretanto para uma melhoria na eficiência da produção, a simples implantação de uma tecnologia industrializada não é o suficiente. Existe a necessidade de melhorar os sistemas de gestão como um todo. O sucesso da implementação de sistemas de planejamento como o Last Planner, desenvolvidos especialmente para a construção civil, instiga o desenvolvimento de estudos em diferentes processos produtivos. Em relação à implementação de princípios da produção enxuta, o sistema é apontado como um ponto de partida para uma empresa atingir uma estabilidade básica. Este estudo foca-se em um tipo específico de sistema de produção industrializadas chamado engineer-to-order (ETO), quando a requisição de produto pelo cliente é realizada na fase de projeto. Neste tipo de sistema construtivo há uma necessidade de integrar a fabricação das peças conforme as necessidades do canteiro de obras. Esta pesquisa visa a desenvolver um modelo integrado de planejamento e controle da produção de sistemas ETO pré-fabricados para construção civil, integrando o projeto, manufatura e montagem em obra. A pesquisa faz parte de uma parceria da Universidade Federal do Rio Grande do Sul com uma empresa de fabricação e montagem de estrutura (Empresa A) metálica interessada em melhorar seus processos de planejamento e controle da produção. O método de pesquisa é baseado na pesquisa construtiva, ou design science, em que há um esforço do pesquisador em produzir um artefato como resultado da pesquisa, que neste caso, é um modelo de planejamento e controle da produção. O processo de implementação de mudanças da empresa adotou a estratégia da pesquisa-ação, de forma que as soluções eram coletivamente acordadas com as pessoas responsáveis pela sua utilização, para garantir que a mesma se efetivasse nos procedimentos da empresa. Neste tipo de estratégia procura-se estabelecer ciclos de aprendizagem ao longo da pesquisa, em que as soluções são continuamente avaliadas e adaptadas para melhoria dos processos em análise. Os resultados da empresa A foram divididos em quatro fases de implementação. Na primeira fase houve um esforço em consolidar uma integração nos planos de curto prazo. Na segunda fase o foco foi no sistema como um todo, promovendo mecanismos para coletar informações sobre o andamento das obras para retroalimentar a fábrica. As barreiras enfrentadas para garantir esta retroalimentação demonstraram a necessidade da utilização de outros métodos. Por isso, a terceira fase se concentrou no desenvolvimento de ferramentas de gestão visual para melhorar os processos analisados nas fases anteriores. A quarta fase do estudo foi baseada no estudo dos processos logísticos da empresa, visto que representam a interface entre fábrica e obra. Terminado o estudo na empresa A dois estudos foram conduzidos no exterior para compreender contextos distintos de sistemas de produção ETO. O primeiro (empresa B) responsável pelo sistema de climatização da edificação. A empresa realiza o projeto, fabricação e instalação dos sistemas de dutos em metal laminado, assim como o maquinário necessário para as trocas de ar. O estudo foi baseado no fornecimento do sistema para uma obra específica. Neste estudo foram desenvolvidas ferramentas de planejamento para facilitar a sincronização entre fabricação e instalação do material em obra. O segundo estudo (empresa C) foi realizado em uma empresa de estrutura metálica que desenvolveu uma conexão inovadora, facilitando seus processos produtivos. Este estudo teve caráter descritivo, analisando como a sua tecnologia facilitou o sistema de planejamento e controle da produção. A partir dos resultados obtidos nos estudos foi possível desenvolver o modelo final de planejamento e controle da produção para sistemas ETO de pré-fabricados. A maioria dos processos propostos neste modelo foi testada na empresa A. Embora a empresa estudada ainda necessite implantar algumas melhorias no seu sistema de planejamento e controle para se adequar ao modelo proposto, as mudanças realizadas trouxeram benefícios na comunicação e sistematização das informações entre os diferentes níveis de planejamento e controle. As contribuições teóricas do trabalho foram um modelo conceitual para compreender a complexidade neste tipo de sistema de produção; a identificação dos principais requisitos para desenvolver sistemas de planejamento e controle da produção para este ambiente; e a adaptação do conceito de WIP utilizando o status dos produtos.
The industrialization of construction work is one of the ways it is possible to achieve better quality and productivity in this competitive environment. However, in order to improve efficiency using industrialized technologies is not enough. There is a need to improve planning and control systems. Although the Last Planner System has been developed for the construction environment, since it was devised the successful results promoted its implementation in different production environments. Regarding lean production implementations, the system has been pointed out as a starting point for a company to achieve the basic stability. This study is focused in one type of industrialized production system: the engineer-to-order. By industrialized, it is the prefabrication that has been addressed. In these kinds of production systems, there is a need to integrate the prefabrication plant with the construction site needs. This research project aims to develop an integrated planning and control production planning and control model for ETO prefabricated systems, integrating design, manufacturing and site assembly. The research is part of a partnership with a steel fabricator company (Company A) that was interested in improving its production planning system. The research method is grounded in the design science research, in which there is an effort from the researcher to develop an artefact as an output of the research process, in this case, a planning and control model. The implementation adopted some strategies from the action-research, so some solutions needed to be collectively constructed between the researcher and the practitioners, in order to have an effective use in the organization. Following this strategy, it is possible to have same learning cycles during the implementation of the solutions, which are continually assessed and adapted in order to improve the processes analysed. The results are divided into four phases of implementation. In the first step the main effort was in consolidating an integrated planning and control process for the short-term in the production units. In the second step the focus was the overall system, mainly providing mechanisms to collect the status of all construction sites for the plant. The barriers to improve this feedback process brought to light the need for using visual management tools. This development concerned the third step of implementation, further improving the changes made in the previous phases. The fourth step was based on the analysis of the logistics processes, as the interface between the plant and site assembly. After the main empirical study on Company A, two studies were carried out abroad in order to understand a different context of ETO production systems. The first concerns a mechanical contractor situated in a high complex project. In this study, it was possible to develop some planning tools to facilitate the analysis between the fabrication and site installation of the products. The second concerns a steel fabricator focused on the structural system. This was a descriptive study that analysed the differentiation of the products provided by this company and the impact of it in the planning and control system. Based on the results obtained in the implementation process, the integrated planning and control model for ETO building systems was devised. Most of the processes proposed in the model were assessed in Company A. Although there is still a need to improve the production planning and control system of that company, the implementation enhanced the communication between the operational and tactics level and also promoted a systematic way to collect information for each level of the production planning and control system. The theoretical contributions of the research were the development of a framework to understand the complexity of this kind of production system; the identification of the main requirements for developing a planning and control system for this environment; and the adaptation of the concept of WIP using the status of the product.

Abstract:
The performance of 26 PVT-Systems was analysed and compared in IEA-SHC Task 60. The systems are located in countries with different climatic conditions. The applications range from direct domestic hot water production and heating of public swimming pools to heat pump systems with PVT as the main heat source of the heat pump. The Key Performance Indicators (KPIs) determined for the different PVT solutions give the possibility to compare the systems despite their diversity. The goal was to show the potential of PVT collectors in different fields of application. The results show that the integration of PVT collectors in different kinds of well-dimensioned systems leads to competitive solutions, both from an energy and a financial perspective. Additionally the answers to a survey about control strategies for PVT systems, showing some main problems and possible solutions, are summarised.

Abstract:
Existing Delta Headwaters Project (DHP) watershed stabilization studies are focused on restoration and stabilization of degraded stream systems. The original watershed studies formerly under the Demonstration Erosion Control (DEC) Project started in the mid 1980s. The watershed stabilization activities are continuing, and because of the vast number of degraded watersheds and limited amount of yearly funding, there is a need for developing a rapid watershed assessment approach to determine which watersheds to prioritize for further work. The goal of this project is to test the FluvialGeomorph (FG) toolkit to determine if the Rapid Geomorphic Assessment approach can identify channel stability trends in Campbell Creek and its main tributary. The FG toolkit (Haring et al. 2019; Haring et al. 2020) is a new rapid watershed assessment approach using high-resolution terrain data (Light Detection and Ranging [LiDAR]) to support U.S. Army Corps of Engineers (USACE) watershed planning. One of the principal goals of the USACE SMART (Specific Measureable Attainable Risk-Informed Timely) Planning is to leverage existing data and resources to complete studies. The FG approach uses existing LiDAR to rapidly assess either reach-specific analysis for smaller more focused studies or larger watersheds or ecosystems. The rapid assessment capability can reduce the time and cost of planning by using existing information to complete a preliminary watershed assessment and provide rapid results regarding where to focus more detailed study efforts.

Abstract:
The main recommendations of the panel report can be summarised under five key headings:  Building blocks: The ultimate aim should be to build rich, detailed and testable narratives situated within a European context, and addressing phenomena from the longue durée to the short-term over international to local scales. Chronological control is essential to this and effective dating strategies are required to enable generation-level analysis. The ‘serendipity factor’ of archaeological work must be enhanced by recognising and getting the most out of information-rich sites as they appear. o There is a pressing need to revisit the archives of excavated sites to extract more information from existing resources, notably through dating programmes targeted at regional sequences – the Western Isles Atlantic roundhouse sequence is an obvious target. o Many areas still lack anything beyond the baldest of settlement sequences, with little understanding of the relations between key site types. There is a need to get at least basic sequences from many more areas, either from sustained regional programmes or targeted sampling exercises. o Much of the methodologically innovative work and new insights have come from long-running research excavations. Such large-scale research projects are an important element in developing new approaches to the Iron Age.  Daily life and practice: There remains great potential to improve the understanding of people’s lives in the Iron Age through fresh approaches to, and integration of, existing and newly-excavated data. o House use. Rigorous analysis and innovative approaches, including experimental archaeology, should be employed to get the most out of the understanding of daily life through the strengths of the Scottish record, such as deposits within buildings, organic preservation and waterlogging. o Material culture. Artefact studies have the potential to be far more integral to understandings of Iron Age societies, both from the rich assemblages of the Atlantic area and less-rich lowland finds. Key areas of concern are basic studies of material groups (including the function of everyday items such as stone and bone tools, and the nature of craft processes – iron, copper alloy, bone/antler and shale offer particularly good evidence). Other key topics are: the role of ‘art’ and other forms of decoration and comparative approaches to assemblages to obtain synthetic views of the uses of material culture. o Field to feast. Subsistence practices are a core area of research essential to understanding past society, but different strands of evidence need to be more fully integrated, with a ‘field to feast’ approach, from production to consumption. The working of agricultural systems is poorly understood, from agricultural processes to cooking practices and cuisine: integrated work between different specialisms would assist greatly. There is a need for conceptual as well as practical perspectives – e.g. how were wild resources conceived? o Ritual practice. There has been valuable work in identifying depositional practices, such as deposition of animals or querns, which are thought to relate to house-based ritual practices, but there is great potential for further pattern-spotting, synthesis and interpretation. Iron Age Scotland: ScARF Panel Report v  Landscapes and regions:  Concepts of ‘region’ or ‘province’, and how they changed over time, need to be critically explored, because they are contentious, poorly defined and highly variable. What did Iron Age people see as their geographical horizons, and how did this change?  Attempts to understand the Iron Age landscape require improved, integrated survey methodologies, as existing approaches are inevitably partial.  Aspects of the landscape’s physical form and cover should be investigated more fully, in terms of vegetation (known only in outline over most of the country) and sea level change in key areas such as the firths of Moray and Forth.  Landscapes beyond settlement merit further work, e.g. the use of the landscape for deposition of objects or people, and what this tells us of contemporary perceptions and beliefs.  Concepts of inherited landscapes (how Iron Age communities saw and used this longlived land) and socal resilience to issues such as climate change should be explored more fully.  Reconstructing Iron Age societies. The changing structure of society over space and time in this period remains poorly understood. Researchers should interrogate the data for better and more explicitly-expressed understandings of social structures and relations between people.  The wider context: Researchers need to engage with the big questions of change on a European level (and beyond). Relationships with neighbouring areas (e.g. England, Ireland) and analogies from other areas (e.g. Scandinavia and the Low Countries) can help inform Scottish studies. Key big topics are: o The nature and effect of the introduction of iron. o The social processes lying behind evidence for movement and contact. o Parallels and differences in social processes and developments. o The changing nature of houses and households over this period, including the role of ‘substantial houses’, from crannogs to brochs, the development and role of complex architecture, and the shift away from roundhouses. o The chronology, nature and meaning of hillforts and other enclosed settlements. o Relationships with the Roman world

Abstract:
This report forecasts growth in developing Asia of 7.1% in 2021 and 5.4% in 2022 in an uneven recovery caused by divergent growth paths. Its theme chapter explores sustainable agriculture. Growth forecasts are revised up for East Asia and Central Asia from the projections made in April, but down for South Asia, Southeast Asia, and the Pacific. This reflects differences in vaccination progress and control of domestic COVID-19 outbreaks but also other factors, including rising commodity prices and depressed tourism. Inflation is expected to remain under control. The main risks to the economic outlook come from the COVID-19 pandemic, including the emergence of new variants, slower-than-expected vaccine rollouts, and waning vaccine effectiveness. Sustainable food production and agricultural systems that are resilient to climate change will be crucial for developing Asia. To transform agriculture in the region, its economies must tackle challenges from changing consumer demand, changing demographics, and a changing and more fragile environment.
