Enabling sustainable service delivery by means of effective demand management in a local municipality / Gabriel Tsietsi Banda

Banda, Gabriel Tsietsi January 2011 (has links)
Over the past months, newspapers and news bulletins are riddled by service delivery protests – to the extent that the President of the country acknowledges these protests. Many reasons were offered for the protests, but the main reason is cited as dissatisfaction with the level of basic services delivered by the municipalities. Questions were asked to obtain possible solutions to the problem. These challenges motivated the researcher to undertake a study to investigate the possible cause of poor delivery of service by municipalities to the communities. A possibility was to study and recommend a possible solution that would ensure that service is delivered on time, at the right price, at the right location and that quantity and quality meet the needs of the community. The system suitable to address this concern is demand management, the first element of the supply chain management system. The purpose of demand management is to ensure that the resources required to fulfil the needs identified during the strategic plan of the municipality, are delivered at the correct time, price and place, and that quantity and quality will satisfy the needs of the users. The research was conducted by means of a literature study and an empirical study. The literature study entails a literature discussion on three variables identified as crucial in achieving the objectives of the study, namely sustainability, demand management and change management. These variables form the basis of the evaluation of the factors which ensure that effectively used demand management results in sustainable service delivery. Delivering sustainable service will ensure that the service is delivered on time, at the right price, at the right location, and quality that meets the needs of the users. These variables were empirically tested in practise by means of a measurement instrument and subsequently evaluated. Based on the evaluation of the empirical study, the demographical data were analysed and concluded on. The reliability and internal consistence of the measurement instrument were determined by means of Cronbach Alpha coefficient. The results of the reliability test revealed that only change management’s Cronbach Alpha coefficient was less than the cut–off value of 0.7. Despite the results of change management’s Cronbach Alpha coefficient, the reliability of the other latent variables was found to be reliable and internally consistent. The variables were analysed and concluded upon by means of a descriptive statistical analysis, using frequency on the questionnaire responds. The arithmetic mean and standard deviation per construct was also calculated, using SPSS (Statistical Package for the Social Sciences). The relationship between the variables was also evaluated through determining the effect size and correlation of coefficient being calculated. Practical recommendations were suggested to address the weaknesses found during the evaluation of the questionnaires, in order to improve future continuity of both municipalities used as unit of measure. Recommendations of future research needed, were also made. / Thesis (MBA)--North-West University, Potchefstroom Campus, 2012.

Optimizing travel: opportunities for the U of M Fort Garry Campus

Pearce, Tom 01 December 2009 (has links)
This thesis examines transportation planning at the University of Manitoba Fort Garry campus with the view to improving efficiency, equity and reducing economic loss. Through a broad approach of Transportation Demand Management (TDM) a number of avenues are explored including a comprehensive literature review of sustainable transportation planning; the documentation of selected university TDM programs including University of Colorado, University of British-Columbia and the University of Ottawa; a University of Manitoba commuter web survey, and key informant interviews. Cost-benefit analysis, geographical information systems and key informants interviews are used. Twelve key recommendations are outlined in the concluding chapter. The research suggests optimal solutions can be reached if there is strong leadership from the University of Manitoba central administration in Transportation Demand Management (TDM) including a more collaborative approach to transportation and land use planning, as well as working closely with its stakeholders in reforming current practices. A series of incremental changes can give higher priority to walking, cycling, transit, and car pooling ahead of those driving alone resulting in a more equitable and efficient transportation system and leading to a healthier population and a healthier environment for the University of Manitoba community.

Temporal De-biasing of Behaviour in Residential Energy Consumption: Supporting Conservation Compliance Through Feedback Design

Trinh, Kevin 11 January 2011 (has links)
Despite years of research in residential energy conservation, means of inducing conservation behaviour through feedback are not well understood. In this thesis I take a novel approach to feedback design by addressing temporal inconsistencies that may hinder individuals from forming an intention to conserve. To help understand conservation compliance strategies, I proposed a visual framework to categorize interventions. I present two design heuristics that were inspired by temporal construal theory (Liberman & Trope, 2003). They were the impetus for the design of three feedback display prototypes, which were examined. Due to methodological limitations, significant improvements to compliance were not found. However, evidence suggests that comparative feedback may have supported reasoning about conservation rather than supporting conservation compliance directly. Future work includes refinement of feedback displays to avoid direct comparisons, exploring the use of nature imagery, and the study of a possible interaction between environmental values and comparative feedback on compliance.

Achieving A Pedestrian Oriented Transportation System In Ankara

Yasdag, Serkan 01 May 2006 (has links) (PDF)
After World War II, automobile use expanded rapidly in the developed countries. As a result, travel pattern changed entirely and automobile has become the dominant form of transport in cities. As a result, the city has been shaped and sized in response to automobile needs. Such increase caused traffic problems in the Central Business Districts and surrounding areas. The problems of traffic congestion and pedestrian circulation have become an important issue in the whole city. As traffic problems have grown in developed cities, they had to be engaged in managing travel demand of people in order to provide mobility and access with reference to the advancing principles of sustainability. In this scope, this study shows the need of travel demand management to create a sustainable transport system. As a case, this study will evaluate the transport problems of Ankara and the place of the city in the urban transport policy process. At this point, transport problems and the transformation of road network and their impacts on the city will be examined in four periods. As a conclusion, urban transportation strategies needed for creating a sustainable transport system are overviewed for the city of Ankara.

Boitumelo-Mfula, Tumisang Sanggy January 2006 (has links)
<p>Botswana's population and water demand are growing at a high rate particularly in the dry south eastern part of the country. In 1999, a Water Conservation Policy and Strategy framework document was formulated to guide a transition from a supply driven water management approach to water demand management. This study investigated whether there was a disparity between the framework policy and strategy recommendations and their actual implementation.</p>

Ricardo Lacerda Baitelo 02 March 2006 (has links)
Esta dissertação propõe um modelo de caracterização de recursos energéticos do lado da demanda que pretende abranger todos os tipos de ações e medidas referentes ao gerenciamento da demanda e à conservação energética, avaliando-as de forma holística, dentro de quatro dimensões: técnico-econômica, ambiental, social e política. Os recursos considerados na composição do modelo são submetidos às fases de Inventário de Recursos Energéticos do Lado da Demanda, Caracterização das Dimensões e Atributos de Avaliação de Recursos, Formulação dos Potenciais Energéticos e Aplicação do Modelo em Caso Piloto. O Inventário de Recursos Energéticos do Lado da Demanda pretende levantar, descrever e segmentar todas as alternativas energéticas de GLD e setores de consumo energético. A Caracterização da Avaliação de Recursos delimita as esferas de análise de recursos e a caracterização de seus atributos quanto a custos e benefícios provenientes de seu emprego. A Formulação dos Potenciais Energéticos define seu cálculo a partir de sua amplitude e restrições gerais de aplicação. O modelo é aplicado em um estudo piloto, na Região Administrativa de Araçatuba, por meio de um exercício de formulação do PIR, considerando a utilização de ferramentas de Avaliação dos Custos Completos, Cálculo de Potenciais Energéticos e Elaboração de Cenários de Projeção do Consumo Energético para um horizonte de tempo determinado. / This work presents a model for the characterization and assessment of demand side energy resources, which intends to comprehend every kind of action or measure related to demand side management and energy conservation, evaluated thouroughly into four dimensions: technical-economical, environmental, social and political. The resources included in the composition of the model are subjected to the stages of Inventary of Demand Side Resources, Characterization of Dimensions and Attributes of the Resources Assessment, Formulation of Energy Potentials and Model Application on a Real Case Study. The Inventary of Demand Side Resources intends to enlist, describe and segment all demand side management energy alternatives and their application in different economy sectors. The Characterization of the Resources Assessment defines the spheres of the assessment of resources and the characterization of its attributes as for costs and benefits resulting from their utilization. The Formulation of Energy Potentials defines their accounting based on their range and general application restrictions. The Model is applied in a case study, in the Administrative Region of Araçatuba, through an exercise of IRP formulation, regarding the utilization of Full Cost Accounting, Energy Potentials Accounting and Scenarios of Energy Consumption for a determined horizon.

Proposta de um novo modelo matemático para gerenciamento ótimo de energia elétrica pelo lado do consumidor /

Sanchez, Luis Carlos January 2017 (has links)
Orientador: Fábio Bertequini Leão / Resumo: No contexto de gestão e conservação de energia elétrica, ferramentas de apoio ao consumidor para gerenciar sua demanda são fundamentais para a otimização do uso dos recursos energéticos de modo a minimizar os custos com energia elétrica e ao mesmo tempo garantir o conforto do consumidor, considerando que este consumidor esteja inserido em um ambiente de Gerenciamento pelo Lado da Demanda (GLD). Assim, este trabalho propõe um novo modelo matemático de programação linear inteira mista (PLIM) para resolver o problema de gerenciamento ótimo de energia elétrica pelo lado do consumidor. O modelo matemático é baseado na minimização do custo da energia elétrica e maximização do conforto do consumidor, levando em conta a minimização da diferença entre o consumo habitual e o consumo ótimo, e a minimização da potência absorvida da rede. O modelo é implementado em linguagem de programação AMPL e resolvido utilizando o solver CPLEX. A metodologia é aplicada para gerenciar um conjunto de cargas típicas residenciais e os resultados mostram sua eficiência e potencial para gerenciar de forma ótima a demanda do consumidor, considerando a tarifa de energia elétrica com preço variável, geração distribuída, armazenamento de energia em banco de baterias e veículos elétricos. / Abstract: In the context of the management and conservation of electric energy, consumer support tools to manage their demand are fundamental for optimizing the use of energy resources in order to minimize energy costs and at the same time guarantee consumer comfort, considering that the consumer is inserted in a Demand Response (DR) environment. Thus, this work proposes a new mathematical model of mixed integer linear programming (MILP) to solve the problem of optimal management of electrical energy by the consumer side. The mathematical model is based on minimizing the cost of electrical energy, maximizing consumer comfort, taking into account the minimization of the difference between habitual consumption and optimal consumption, and minimizing the power consumed by the network. The model is implemented in AMPL programming language and solved using the CPLEX solver. The methodology is applied to manage a set of typical residential loads and the results show its efficiency and potential to optimally manage the consumer demand, considering the price of electricity with variable price, distributed generation, storage of energy in bank of batteries and electric vehicles. / Mestre

Mobilidade corporativa : como engajar organizações brasileiras em prol da melhoria do transporte urbano

Petzhold, Guillermo Sant'Anna January 2016 (has links)
A contínua ampliação da infraestrutura viária já se provou ineficaz em resolver os problemas de congestionamento nos grandes centros urbanos e uma solução não sustentável tendo em vista os altos investimentos envolvidos. Em contraposição ao tradicional aumento da capacidade viária, surge a Gestão da Demanda de Viagens (GDV). Uma das medidas englobadas pela GDV é a mobilidade corporativa que visa a promover o uso de opções de transporte mais sustentáveis e eficientes nos deslocamentos casa-trabalho das pessoas. Aproximadamente 50% dos deslocamentos diários nas cidades brasileiras ocorrem por motivo de trabalho. Por isso organizações públicas e privadas desempenham um papel fundamental em questões atreladas ao transporte. Embora não controlem a forma como seus funcionários vão ao trabalho, as organizações, por muitas vezes, podem estimular a mudança de hábitos de deslocamento ao prover informações e incentivos para isso. Este trabalho tem por objetivo verificar a aplicabilidade da adoção de estratégias de mobilidade corporativa em organizações situadas no Brasil. Em um primeiro momento, apresenta-se mais profundamente o conceito, os benefícios e as medidas de mobilidade corporativa que podem ser implementadas. A seguir, são comparados e analisados diferentes métodos existentes para a elaboração de planos de mobilidade corporativa. Propõe-se um novo método adaptado à realidade local composto por sete passos que totalizam 26 atividades que devem ser cumpridas para a construção de um plano bem-sucedido. Realiza-se uma pesquisa-ação em um complexo administrativo que reúne 17 mil funcionários e está localizado a 20 km do centro da cidade. Investiga-se o padrão de deslocamento casa-trabalho dos funcionários da organização e são analisadas que medidas de mobilidade corporativa poderiam ser adotadas para estimular o transporte sustentável entre os funcionários deste local. / The continuous expansion of road infrastructure has proven to be ineffective in solving the problem of congestion in large urban areas. It is also an unsustainable solution due to the high investments involved. Instead of increasing road capacity, Travel Demand Management (TDM) emerges as an alternative to deal with the problem. One of TDM’s measures is corporate mobility, which aims to promote more sustainable and efficient transport options for commuting to work. Approximately 50% of daily trips in Brazilian cities are work related. Therefore public and private organizations play a key role in issues related to transportation. Although they do not control how employees commute to work, organizations have the ability to stimulate travel behavior change by providing information and incentives. This study aims to verify the applicability of the adoption of corporate mobility strategies in organizations located in Brazil. At first, a more in depth concept is explained in addition to the benefits and corporate mobility measures that can be implemented. Then, we compare and analyze different existing methods for the construction of corporate mobility plans. We propose a new method based on the local context. The method is composed by seven steps totalizing 26 activities which must be followed for developing of a successful plan. Finally, we describe the application of the method that was carried out in an Administrative Center which gathers 17 thousand employees and is located 20 km away from the city center. We investigate employees’ commute patterns and analyze which corporate mobility measures could be implemented to promote a more sustainable commute pattern to work.
