This study was made to gather data and information to aid the Burleson Independent School District in initiating an industrial arts general shop program in the Pauline G. Hughes Middle School. The data and information were obtained from the Texas Education Agency, the Burleson Independent School District records, the vocational director, the assistant superintendent, a questionnaire, and the Brodhead-Garrett 1976-1977 Catalog. The majority of the general shop programs in the north Texas area conduct classes five days a week for fifty-five minutes a day and accommodate twenty-four students per class. Furthermore, the majority of the general shop programs offer three units of instruction per year and teach one unit of instruction each quarter.

Atualmente, os hospitais se veem obrigados a melhorar sua produtividade. Os centros cirúrgicos, além de ser um dos setores com maiores custos, também é o que mais gera receita dentro de um hospital, dessa forma torna-se extremamente importante o gerenciamento eficiente desse setor. Os métodos de otimização para programação de cirurgias podem ser usados como ferramentas para reduzir filas e ociosidade nos centros cirúrgicos, aumentando sua produtividade. O Problema de Programação de Cirurgias Eletivas com Múltiplos Recursos e Múltiplas Etapas consiste em alocar os recursos às etapas do processo cirúrgico dos pacientes, considerando as diferentes necessidades e rotas de cada paciente e, então, programar essas etapas no tempo respeitando a disponibilidade dos recursos e a sequência das etapas do processo cirúrgico dos pacientes. Esse problema é classificado na literatura como NP-hard e pode ser descrito como um Job Shop Flexível com blocking e função objetivo de minimização do número de pacientes não atendidos e do instante de término da última etapa, o makespan. O Objetivo desse trabalho é propor um modelo matemático e uma heurística construtiva para a resolução desse problema. O modelo matemático Multi-Mode Blocking Job Shop (MMBJS) apresentado em Pham e Klikert (2008) é explorado e algumas melhorias são apontadas neste trabalho. Um modelo matemático de Programação Linear Inteira Mista alternativo é proposto, a fim de reduzir o esforço computacional, ajustar o cálculo do makespan e sugerir uma estratégia de priorização de pacientes. Testes computacionais foram realizados, afim de comparar o modelo MMJBS e o modelo proposto. Para instâncias em que todos os pacientes são atendidos, as soluções encontradas pelo CPLEX para ambos modelos são iguais, porém o tempo computacional necessário para encontrar uma solução ótima é em média 45% menor no modelo proposto. Também foram realizados testes computacionais com objetivo de observar o comportamento do modelo com diferentes configurações de recursos. Para instâncias com 15 pacientes, os testes apontam que o tempo computacional para encontrar a solução ótima é superior a 2h de processamento. Dessa forma, uma heurística construtiva é proposta, com objetivo de gerar soluções factíveis com pouco esforço computacional. A heurística proposta aloca cada etapa do tratamento de cada paciente aos recursos necessários, respeitando as janelas de disponibilidade dos recursos e buscando reduzir a folga no sistema. Um exemplo de aplicação da heurística construtiva é apresentado. As propostas para trabalhos futuros são apresentadas no capítulo final desta dissertação. / For the past few years, hospitals have been forced to improve their productivity, with surgical centers being one of the sectors with higher costs within such organizations, but also the ones that generate the most revenue. Thus, optimization methods for surgical programming are tools that can be used to reduce queues and idleness in these sectors and consequently achieve the aforementioned goals. The \"Problem of Programming Multiple Surgical Resources with Multiple Steps\"consists in allocating the existing resources to each surgery stage that a patient will need to go through, considering the different needs, sequence and specificities of each of them, and then scheduling these steps in time. This type of problem is classified in the current literature as an NP-hard problem, being described as a Flexible Job Shop with blocking and an objective function that seeks to minimize the number of patients not served and the total makespan. The general purpose of this research is to propose a mathematical model and a constructive heuristic for this type problem. The proposed model explores the mathematical model Multi-Mode Blocking Job Shop (MMBJS) presented in Pham and Klikert (2008) suggesting improvements through the use of an alternative Mixed Integer Linear Programming that aims to: reduce the computational effort, adjust the makespan calculation and suggest a strategy of patients prioritization. In order to prove the benefits of the proposed enhancements, computational tests were performed to compare the MMJBS model and the proposed model, identifying that for instances where in which all patients are attended, the solutions found by CPLEX for both models are the same, but with a lower computational time the proposed model (45% average reduction). Also, other computational tests were performed to observe the behavior of the model with different configurations of resources. For instances with 15 patients, the tests indicate that the computational time to find the optimal solution is greater than 2 hours of processing. Thus a constructive heuristic is proposed, it aims to generate feasible solutions with little computational effort. The proposed heuristic allocates each surgery stage of a patient to the necessary resources, respecting the available windows and seeking to reduce the total slack in the system. An example of the application of the constructive heuristic is also presented. At last, future works proposals are presented in the final chapter of this dissertation.

Alternative food networks in a post-communist context:: Farmers' markets and farm shops in Czechia Marie Syrovátková ABSTRACT The emergence of farmers' markets (FMs) and farm shops (FSs) in Czechia is a follow-up of the expansion of alternative food networks (AFNs) from Western Europe and North America where they have been developing for several decades. AFNs are an up-to-date topic as they respond to the growing concerns about the negative effects of the globalized conventional food system on social, economic and environmental aspects of food production, distribution and consumption. Each form of AFNs emphasizes a different aspect of the food system sustainability. FMs and FSs should primarily enable direct selling of quality local products made by small producers to support local economy, rural development, environmental protection and to improve quality of life. Based on a combination of quantitative and qualitative methods, the aim of the dissertation is to explore the emergence and development of AFNs in Central Europe. Using the example of Czechia, considering the communist past of the region, the work evaluates the contribution of AFNs to build a more sustainable system of food production and consumption and the weak points of the phenomenon in Czechia and, using a comparison of the AFN evolution...

Growing concerns over global warming and increasing fuel costs have pushed the traditional fuel-based centralized electrical grid to the forefront of mounting public pressure. These concerns will only intensify in the future, owing to the growth in electricity demand. Such growths require increased generation of electricity to meet the demand, and this means more carbon footprint from the electrical grid. To meet the growing demand economically by using clean sources of energy, the electrical grid needs significant structural and operational changes to cope with various challenges. Microgrids (µGs) can be an answer to the structural requirement of the electrical grid. µGs integrate renewables and serve local needs, thereby, reducing line losses and improving resiliency. However, stochastic nature of electricity harvest from renewables makes its integration into the grid challenging. The time varying and intermittent<br>nature of renewables and consumer demand can be mitigated by the use of storages and dynamic load scheduling. Automated dynamic load scheduling constitutes the operational changes that could enable us to achieve energy efficiency in the grid.<br>The current research works on automated load scheduling primarily focuses on scheduling residential and commercial building loads, while the current research on manufacturing scheduling is based on static approaches with very scarce literature on job shop scheduling. However, residential, commercial and, industrial sector, each contribute to about one-third of the total electricity consumption. A few research<br>works have been done focusing on dynamic scheduling in manufacturing facilities for energy efficiency. In a smart grid scenario, consumers are coupled through electricity<br>pool and storage. Thus, this research investigates the problem of integrating production line loads with building loads for optimal scheduling to reduce the total electricity<br>cost in a µG.<br>This research focuses on integrating the different types of loads from different types of consumers using automated dynamic load scheduling framework for sequential decision making. After building a deterministic model to be used as a benchmark, dynamic load scheduling models are constructed. Firstly, an intelligent algorithm is developed for load scheduling from a consumer’s perspective. Secondly, load scheduling model is developed based on central grid controller’s perspective. And finally, a reinforcement learning model is developed for improved load scheduling by sharing<br>among multiple µGs. The performance of the algorithms is compared against different well-known individualistic strategies, static strategies and, optimal benchmark<br>solutions. The proposed dynamic load scheduling framework is model free with minimum assumptions and it outperforms the different well-known heuristics and static strategies while obtains solutions comparable to the optimal benchmark solution.<br>The future electrical grid is envisioned to be an interconnected network of µGs. In addition to the automated load scheduling in a µG, coordination among µGs by<br>demand and capacity sharing can also be used to mitigate stochastic nature of supply and demand in an electrical grid. In this research, demand and resource sharing<br>among µGs is proposed to leverage the interaction between the different µGs for developing load scheduling policy based on reinforcement learning. <br>

O tema da cultura organizacional tem sido visivelmente aprofundado a partir de mudanças na sua base epistemológica (de um paradigma funcionalista para um interpretativista) e na utilização de diferentes perspectivas conceituais (de uma abordagem gerencial para uma simbólica) e metodológicas (de pesquisas quantitativas para qualitativas). Todavia, a despeito de todos esses avanços, o tema não tem acompanhado o desenvolvimento alcançado pelos estudos antropológicos que enfocam o corpo como modo de repensar a problemática cultural. É meu objetivo nesta tese, portanto, desvelar de que modo um enfoque no corpo humano propicia um melhor entendimento da noção de cultura organizacional, a partir de dois eixos teóricos que trabalham com a relação corpo-cultura: o ‘corpo artefato’ (corpo sócio-histórico-cultural) e o ‘embodiment’ (experiência cultural incorporada). Para realizar ambas as análises, parto de observações oriundas de uma etnografia organizacional junto a uma grande livraria de shopping center, a Livraria Cultura de Porto Alegre. O grupo de informantes privilegiado nessas análises foi a equipe de vendedores. Com base nesse material empírico e, primeiramente, com base em estudos da Antropologia do Corpo (capítulo 2), na primeira parte deste trabalho, analisei o corpo do trabalhador como um artefato organizacional que se singulariza por seu caráter dinâmico, sua hierarquização e sua dimensão política. A partir dessas análises, foi possível repensar o caráter de objeto inanimado e a pouca atenção que é oferecida para questões como classificação, hierarquização e dimensão política dos artefatos organizacionais. Na segunda parte (capítulo 3), aponto para a relação cultural pré-objetiva (pré-reflexiva) que trabalhadores estabelecem com as organizações e com os produtos que comercializam, ou seja, como a cultura organizacional é experienciada e incorporada. Para isso, parto de estudos da Filosofia e de Ciências Sociais e Humanas para buscar compreender como os estudos de embodiment possibilitam um novo modo de se conduzir metodologicamente as pesquisas de cultura organizacional e como incrementam sua conceituação. Levantei que o foco no embodiment desvela o papel ativo que o corpo tem na vida organizacional e permite uma melhor compreensão da dinâmica do conceito de cultura. / The theme of organizational culture has been visibly deepened – changing its epistemological base (from a Functionalist paradigm to an interpretative one) generating different conceptual (from a managerial to a symbolic approach) and methodological perspectives (from quantitative to qualitative researches). However, in spite of all these advances, the theme has not been following the development reached by anthropological studies, which focus the body as a form of representing the culture. Therefore, it is my aim in this thesis to unveil in what way the focus on the human body propitiates a better understanding of the notion of organizational culture, starting from two theoretical orientations which work with the relation body-culture: the ‘body artifact’ (socio-historiccultural body) and the ‘embodiment’. In order to perform both analyses, I begin with observations resulting from an organizational ethnography in a great bookstore of shopping center, Livraria Cultura de Porto Alegre. The group of informers who have been privileged to participate in these analyses was the team of shop assistants. Based on this empirical material and, firstly, on studies of The Anthropology of Body (chapter two), I analyzed the body of the worker as an organizational artifact which is singularized by their dynamic feature, hierarchization, and political dimension. Based on these analyses, it was possible to reconsider the feature of inanimate object and the little attention that is offered to questions like classification, hierarchization, and political dimension of organizational artifacts. In the second part (chapter three), I indicate the pre-objective cultural relation (pre-reflexive) that the workers establish with the organizations and the products they commercialize, that is, the embodiment of organizational culture. Hence, I start from studies of Philosophy, Social, and Human Sciences to understand how studies of embodiment enable a new form of conducting methodologically researches about organizational culture and how they develop their conceptualization. I indicate that the focus on embodiment unveil the active role the body has in the organizational life and allows a better understanding of the dynamics of cultural concept.

A need has been established in industry and academic publications to link an engine's maintenance costs throughout its operational life to its design as well as its operations and operating conditions. The established correlations between engine operation, design and maintenance costs highlight the value of establishing a satisfactory measure of the relative damage due to different operating conditions (operational severity). The methodology developed in this research enables the exploration of the causal, physics-based relationships underlying the statistical correlations in the public domain and identifies areas for further investigation. This thesis describes a physics-based approach to exploring the interactions, for commercial aircraft, of engine design, operation and through life maintenance costs. Applying the "virtual-workshop" workscoping concept to model engine maintenance throughout the operating life captures the maintenance requirements at each shop visit and the impact of a given shop visit on the timing and requirements for subsequent visits. Comparisons can thus be made between the cost implications of alternative operating regimes, flight profiles and maintenance strategies, taking into account engine design, age, operation and severity. The workscoping model developed operates within a physics-based methodology developed collaboratively within the research group which encompasses engine performance, lifing and operational severity modelling. The tool-set of coupled models used in this research additionally includes the workscoping maintenance cost model developed and implements a simplified 3D turbine blade geometry, new lifing models and an additional lifing mechanism (Thermo-mechanical fatigue (TMF)). Case studies presented model the effects of different outside air temperatures, reduced thrust operations (derate), flight durations and maintenance decisions. The use of operational severity and exhaust gas temperature margin deterioration as physics based cost drivers, while commonly accepted, limit the comparability of the results to other engine-aircraft pairs as the definition of operational severity, its derivation and application vary widely. The use of a single operation severity per mission based on high pressure turbine blade life does not permit the maintenance to vary with the prevalent lifing mechanism type (cyclic/steady state).

The purpose of this thesis is to develop a model to enhance the effectiveness of machining centers with multi-pallet automatic pallet changers (APCs). From critical literature review no existing theories within this field were found. The multi-pallet APC allows multi-setups and a more flexible sequencing of jobs. The model together with the developed heuristic scheduling algorithm with the objective to minimize the total weighted tardiness can be used to plan in n jobs on m pallets in a shop-floor. The right maintenance policy ensures a high availability, which together with the program guarantees a high level of utilization of the machinery. Consequently the effectiveness will be enhanced. A case study approach was used to test the model at Växjöfabriken in Sweden, which treats cast material. The results of this case study are a more effective utilization of the machines with decreased tardiness costs, increased customers’ satisfaction and goodwill of the company. The contribution of this thesis is a model with a flexible, adjustable and expandable heuristic scheduling algorithm, which can be applied in all manufacturing companies using machining centers with multi-pallet APCs. / Syftet med denna uppsats är att utveckla en modell för att förbättra effektiviteten av maskincentra med automatiska palletväxlare (APCs) för multi-palleter. När en kritisk litteratursökning genomfördes hittades inga relevanta teorier inom det aktuella området. Multi-pallet APC tillåter att många jobb kan förberedas samtidigt och gör planeringen av jobben mer flexibel. Modellen, tillsammans med den utvecklade heuristiska planeringsalgoritmen med målet att minimera den totala viktade förseningen, kan användas för att planera in n jobb med m palleter på ett verkstadsgolv. Rätt underhålls policy försäkrar en hög tillgänglighet vilket tillsammans med programmet garanterar en hög utnyttjandenivå av maskinerna. Som följd kommer effektiviteten att höjas. En fallstudie utfördes på Växjöfabriken i Sverige för att utvärdera modellen, på företaget efterbehandlas gjutgods. Resultatet från denna fallstudie blev ett effektivare utnyttjande av maskinerna, med minskade förseningskostnader, ökad kundtillfredställelse och goodwill för företaget. Denna uppsats bidrar med en modell och en flexibel, anpassningsbar och utvecklingsbar heuristisk planeringsalgoritm, vilken kan användas i alla industriföretag som använder maskincentra med multi-pallet APCs.

Background: These days in uncertain circumstances and economic downturn, innovation is very important for organizations. This applies also on Dutch franchise retail organizations (DFRO’s) and its suppliers, which are in focus in this thesis. The authors argue that shop employees working in the physical shops are a valuable source of innovation and can function as a pass-through of consumer information to the management of a DFRO and its suppliers.The main question is, if and how DFRO’s and its supplier use shop employees as a source of innovation? Purpose: To describe and explore the involvement of shop employees in the innovation process of Dutch franchise retail organizations and its suppliers; and to find out possible advantages and disadvantages of shop employees’ involvement in the innovation processes, and directions of innovation in which shop employees are involved. Method: This thesis is written from a social constructivism perspective with the use of a deductive approach. A holistic multiple case-study of eight Dutch franchise retail organizations was applied by using qualitative method. To collect the empirical data 23 semi-structured interviews with shop employees were conducted in combination with several observations. The collected empirical data was analyzed by using cross-case synthesis method. The research quality is based upon trustworthiness and authenticity. Results and conclusions: The highest degree of involvement of the shop employees in the innovation process by both management and suppliers takes place in the last three stages of the innovation process, which are validation, commercialization and evaluation, in offer- and support-related directions of innovations. In other words, the shop employees are more involved in the innovation process in their own working environment rather than in the decision-making level. The results of the study show that shop employees are willing to be more involved in the innovation process and see more advantages than disadvantages for management, suppliers and themselves. Suggestions for future research: Since this thesis gives interesting results, the future research could be done to strengthen and expand those. The authors suggest to increase the amount of researched DFRO’s; to research multiple shop locations of the same DFRO; to take the position, responsibilities and working period of the shop employees more into consideration. Also the authors see a necessity of future research to confirm the mentioned possible disadvantages and advantages of shop employees’ involvement out of a different perspective.
