The aim of this thesis is to create the design of a robotic workstation (RWS) for storing bags on a pallets with a capacity of 600 bags per hour. As an introduction to the issues of solved task, the introductory part of the thesis deals with a general information about industrial robots, theories ofdesigning RWS and palletization. For the suggested workstation it is given to have one pickup place from the roller conveyor and two unloading places. Within the RWS it is used belt, roller and chain conveyors as a peripheral device for conveying bags and pallets. There are two variants of RWS created for the possibility of technically - economic assessment. Solution for the security and the ergonomy of the workplace are an integral part of the study. Selected components of RWS have their risk analysis carried out. There is also the draft of a robot gripper mentioned, including assembly drawing. In conclussion there is calculation of returning of funds invested in the construction of RWS. Drawings of robotized workplace disposition, schemes of pneumatic and electrical connections and block diagram of the control system of RWS are included as attachments.

<p dir="ltr">Conservation conflicts, commonly defined as “situations that occur when two or more parties with strongly held opinions clash over conservation objectives, and when one party is perceived to assert its interests at the expense of another” (Redpath et al., 2013) are expected within the realm of public land management. Conservation conflicts have been an increasing issue worldwide as the consumption of natural resources can directly oppose conservation efforts. Quantitative and qualitative approaches have been adopted in similar studies to mitigate or resolve conservation conflicts. This thesis focuses on a 2017 conflict over logging in Yellowwood State Forest in Indiana. The Social Multi-Criteria Evaluation (SMCE) framework was applied in this thesis to examine economic, ecological, and recreational criteria from multiple stakeholders' perspectives and understand how a retrospective assessment can contribute to improved conflict resolution. The study follows four steps: conducting an institutional analysis, defining criteria and potential alternative scenarios, generating an impact matrix through surveys and interviews, and aggregating results for cross-scenario comparison. The design of these steps attempts to engage stakeholders in the decision-making process and increase transparency. The ranking results reveal a clear preference for the “Shelterwood Cuts” alternative, indicating that different actions may have been a better solution. Although the methodology alone cannot make decisions, it can aid the decision-maker in creating a solution to a conservation conflict by providing guidance and bringing attention to the aspects of a conflict that require change.</p>

The recent global financial crisis, regulatory and compliance requirements placed on organisations, and the need for scientific research in the project portfolio management discipline were factors that motivated this research. The interest and contribution to the body of knowledge in project portfolio management has been growing significantly in recent years, however, there still appears to be a misalignment between literature and practice. A particular area of concern is the decision-making, during the management of the portfolio, regarding which projects to accelerate, suspend, or terminate. A lack of determining the individual and cumulative contribution of projects to strategic objectives leads to poorly informed decisions that negate the positive effect that project portfolio management could have in an organisation. The focus of this research is, therefore, aimed at providing a mechanism to determine the individual and cumulative contribution of projects to strategic objectives so that the right decisions can be made regarding those projects. This thesis begins with providing a context for project portfolio management by confirming a definition and providing a theoretical background through related theories. An investigation into the practice of project portfolio management then provides insight into the alignment between literature and practice and confirms the problem that needed to be addressed. A conceptual model provides a solution to the problem of determining the individual and cumulative contribution of projects to strategic objectives. The researcher illustrates how the model can be extended before verifying and validating the conceptual model. Having the ability to determine the contributions of projects to strategic objectives affords decision makers the opportunity to conduct what-if scenarios, enabled through the use of dashboards as a visualization technique, in order to test the impact of their decisions before committing them. This ensures that the right decisions regarding the project portfolio are made and that the maximum benefit regarding the strategic objectives is achieved. This research provides the mechanism to enable better-informed decision- making regarding the project portfolio. / Computing / D. Phil. (Computer science)

Zur Einschätzungen und Bewertung der Nachhaltigkeit der gegenwärtigen Gemüseproduktion im Roten-Fluss-Delta, Vietnam, erfolgten empirische Untersuchungen zur Ermittlung und Bewertung eines Nachhaltigkeitsindex unter Nutzung verschiedener Lösungsansätze. Die Analysen und Einschätzungen wurden aus ökologischer ökonomischer und sozialer Sicht vorgenommen. Die erfassten Daten wurden unter Nutzung von zwei Methoden ausgewertet, der Mehr-Kriterien-Bewertungsmethode Analytic Hierarchy Process (AHP) und der Fuzzy Bewertungsmethode. In Workshops wurden mit den Farmern Präferenzen als Element der AHP, zu den Kriterien die Ausdruck der Nachhaltigkeit sind, erarbeitet. Es wurde herausgearbeitet, dass im ländlichen Raum, die Gemüseproduktion nachhaltig ist, im Peri-urbanen Raum wurde eine geringe Nachhaltigkeit ermittelt und im urbanen Raum keine Nachhaltigkeit. Im Ergebnis der Forschungsarbeit wurde herausgearbeitet, dass für einen nachhaltigen Gemüse-Anbau im Roten-Fluss-Delta, die Farmer ihr Kontrollsystem und System der Nachverfolgbarkeit verbessern müssen. Gleichermaßen ist es erforderlich die sozialen Bedingungen so zu gestalten, das die Prinzipien der‚ Guten Landwirtschaftlichen Praxis‘ greifen. Im Rahmen der Forschungsarbeit konnte gleichfalls eine Bewertung der Nachhaltigkeit unter Nutzung der Fuzzy Methode erfolgreich eingesetzt werden. Diese Ergebnisse sind geeignet, sowohl den Farmern, als auch den politischen Entscheidungsträgern, die geeigneten Werkzeuge für die Entwicklung einer nachhaltigen Gemüse Kultivierung in der Zukunft zu geben. / This study is empirical research by applying different sustainability assessment approaches to evaluate and to compare the sustainability index of the existing vegetable cultivation systems in the Red River Delta - the largest vegetable production land area of Vietnam in terms of environment, economic and social dimensions. In addition, this study also incorporated farmers'' perceptions as well as their preferences into the weight of criteria by using Analytic Hierarchy Process (AHP) in multi-criteria evaluation method, and rules formed in fuzzy evaluation method. The results from the sustainability assessment for the vegetable cultivation systems show that in the rural area, the sustainability are acceptable whereas in the peri-urban area are only conditionally acceptable, and in the urban area are not sustainable. The results from this study indicate that, to achieve sustainable vegetable cultivation systems in the Red River Delta in Vietnam, the farmers need improved internal controls and tracing systems as well as strict social control in order to implement good agricultural practices guidelines. This study result also shows that the sustainability assessment by fuzzy evaluation approach appears to be well suited to provide quantitative answers pertaining to sustainability that can help policy maker in choosing the tool for sustainability assessment in the future.

L’agriculture française est soumise à de fortes pressions. Elle subit une injonction forte à évoluer vers l’agroécologie, à adopter les principes de la production intégrée, à réduire l’usage de pesticides. Dans ces conditions, une transition vers des systèmes agricoles plus respectueux de l’environnement ne doit pas dégrader la compétitivité des exploitations et le revenu des agriculteurs.Le travail présenté ici a pour ambition de contribuer à la réflexion sur les possibilités de changer les modèles d’agriculture. L’objectif est d’évaluer les conséquences économiques et environnementales d’une adoption généralisée des principes de protection intégrée sur une région agricole en fonction de la diversité des situations de production. La Région Bourgogne est retenue dans le cadre de ce travail. Elle dispose de ressources expérimentales en production intégrée grâce à l’investissement historique de la recherche, du développement et de l’enseignement agricole dans cette région. Par ailleurs, la Bourgogne présente un bon compromis entre la diversité de ses situations de production en grandes cultures et le nombre de situations contrastées à considérer pour rendre compte de l’ensemble du territoire. Dans un premier temps, nous avons caractérisé la diversité des situations de production de la Bourgogne et la diversité des systèmes de culture, et nous avons étudié comment les systèmes de culture sont déterminés par les situations de production. Puis nous avons mis en place une méthode pour générer des systèmes de culture optimisés sur le plan économique dans le cadre des contraintes locales et des principes de protection intégrée. Cette méthode mobilise la programmation linéaire sous contrainte, mise en œuvre avec le logiciel GAMS. Elle a été testée pour deux situations de production contrastées de la Bourgogne, correspondant aux zones de plaines sans élevage et aux plateaux argilo-calcaires superficiels. Nous avons évalué les systèmes de culture simulés pour un ensemble de critères de la durabilité économique, sociale et environnementale. Nous les avons comparés aux performances des systèmes actuels dans ces milieux.Les résultats confirment que les systèmes de culture optimisés avec les principes de la protection intégrée sont différents en fonction du contexte de production. La performance économique est plutôt améliorée par rapport aux systèmes actuels dans la situation à fort potentiel, alors qu’elle est dégradée sur les sols de plateaux. Tous les indicateurs environnementaux considérés sont améliorés dans les deux types de milieu. Le travail permet d’identifier certains inconvénients de la protection intégrée, liés à l’augmentation de la charge de travail et à la complexité de gestion des systèmes.Avec les résultats obtenus et les méthodes proposées, le travail alimente les débats sur la durabilité des systèmes agricoles dans le domaine des grandes cultures. / The agriculture in France is under intense pressure. Farmers are asked to change their crop management, to evolve toward agroecology, to follow the principles of Integrated Pest Management (IPM) and to reduce pesticide use. However such an evolution toward an alternative agricultural model will be possible only if innovative cropping systems are able to maintain competitive and profitable farms.The aim of our work is to contribute to the debates about this issue, by evaluating ex ante the potential consequences of adopting the principles of IPM over one whole agricultural region, taking into account the diversity of production situations within this region. We considered the Burgundy region for several reasons. This region has many experimental resources and available expertise on IPM. This agricultural area also has few but contrasted production situations. Both economic and environmental issues were considered.First, we studied the diversity of production situations and of cropping systems in the area, based on agricultural data sets, and we showed to what extent cropping systems are determined by the context. Then we developed a method to design fictive cropping systems, based on the optimisation of profitability while fulfilling the principles of IPM, and considering the constraints of the production situation. We used the GAMS software to implement this method based on linear programming. The method was tested on two contrasted production situations, namely the lowlands with high agricultural potential and no livestock, and the shallow soils of the plateau. We evaluated the generated cropping systems for a range of criteria covering different issues of sustainability, and we compared the performances to those of current cropping systems in these areas.Results corroborated that IPM-based cropping systems would be different in contrasted production situations. Profitability would be improved in the lowlands with high agricultural potential, whereas it would be negatively affected in the shallow soils of the uplands. All the environmental indicators that we used would be improved in both situations. Our work identified hindrances for the development of IPM, related for example to the increase in the workload at the farm level, and the increase in the system complexity.Both methods that we developed and the results we obtained should contribute to the current debates about the possible transition of arable cropping toward sustainability.

Esta pesquisa de doutorado faz uma avaliação correlacional entre a evolução espacial da rede de monitoramento de qualidade das águas interiores do Estado de São Paulo, através do número de pontos de amostragem e sua respectiva densidade espacial ao longo dos 30 anos de existência da mesma e o crescimento populacional, através da densidade populacional dos municípios inseridos nas 22 unidades de gerenciamento de recursos hídricos do Estado de São Paulo. Analisa também se estes pontos mantiveram a capacidade de representar o status da qualidade da água em função do crescimento populacional, e se é necessário expandir ou adensar a rede em determinadas regiões. Esta comparação ficou mais racional com o uso dos recursos das geotecnologias e da análise multicritério aplicada ao planejamento e gerenciamento de recursos hídricos, com a construção do SIG SP_WATERNET e através da criação de um índice de avaliação do monitoramento que relaciona as 22 unidades espacialmente e ao longo do período estudado. Este índice pode ressaltar o grau de abrangência e de vulnerabilidade da rede de monitoramento das águas interiores superficiais no Estado de São Paulo. / This Ph.D. research makes a correlational evaluation between the spatial evolution of the monitoring network of inland surface waters of State of São Paulo, through the number of sampling points and its density throughout the 30 years of existence of same and the population growth (urbanization) and the population density in the 22 units of water management units of the São Paulo State. It also analyzes if these points had kept the capacity to represent the status of the quality of the water in function of the population growth, and if it is necessary to expand or to rearrange the network in some regions. This comparison was more rational with the use of the resources of the geo-information applied for water resources planning and management, with the construction of SIG SP_WATERNET and with the proposal of an multi-criteria evaluation monitoring index concerning the 22 water management units throughout a studied period. This index can point out the coverage or the vulnerability of the monitoring efficiency of the superficial waters network of São Paulo State.
