A linear programming approach for designing a herbaceous biomass delivery systemDias, Neil Pravin 24 January 2009 (has links)
There are a variety of systems-related issues associated with the production and distribution of herbaceous biomass from supply points to a centrally located plant. This modeling effort is directed toward the design of such a biomass delivery system that incorporates storage, scheduling and transportation issues. A statement of the problem along with its salient characteristics is presented and a linear programming model is constructed to represent it. The nondeterministic aspects of the system related to uncertainty in production levels due to weather is addressed by reformulating the linear program as a two-stage problem with recourse. This enables the incorporation of alternative scenarios to enhance the decision-making process. A specific case study of a plant located in a county in the Piedmont of Virginia, is considered. The model is solved using the data set for this study, and appropriate sensitivity analyses are conducted to illustrate the range of decision-making options that are available to facilitate an effective systems planning exercise aimed at minimizing cost subject to operational constraints. Specific areas for further research are also identified. / Master of Science

Understanding the relationship between information systems investment and organisational performance: developing and testing a conceptual model in the Australian financial services sectorMaimbo, Hilangwa January 2004 (has links)
The research reported in this thesis was an exploratory study that investigated the relationship between Information Systems (IS) investment and organisational performance and which led to the successfd development and testing of a combined process and variance model that sought to explain this complex relationship. The focal industry was the Australian Financial Services Sector (FSS), with samples being drawn from both the credit union industry (largest industry by size in the FSS) and the commercial/retail bank industry (largest industry by volume). The research began with a detailed review of the literature and thus explored the concepts underlying the business value of IS in general and the relationship between IS investment and organisational performance in particular. To fuaher enhance understanding of this literature, a meta-analysis of the business value of IS in general, and IS investment and organisational performance in particular, was undertaken as it was noted that there did not appear to have been any such formal structured meta-analyses to date. The foregoing analyses led to the proposal and development of a conceptual model of the relationship between IS investment and organisational performance that was comprised of four main components, the level of IS investment as represented by the IT portfolio, Organisational performance (both internal and external), Considerations for Strategic Information Systems Planning and Managerial effectiveness. In addition, the conceptual model explicitly considered the effect and impact of Context on the conceptual model. Further, analysis of subsequent results was strongly grounded in the literature and utilised three key theoretical foundations, General Systems Theory, The Resource Based View of IT and Stakeholder theory. / Thus, the conceptual model was developed and tested utilising a pluralist approach combining two research methods, a) Case research (model development and testing) and b) survey research (model refinement). The collection (and analysis) of data was achieved in two parts. First, given the complexity of the issues under investigation, a unique case study protocol was successfully developed and applied to a select group of Financial Institutions with the Commercial/retail Banking and Credit Union industries to confirm the components of the original conceptual model. Second, the resultant model(s) were tested via a survey targeted at the wider population of Authorised Deposit-taking Institutions in the Australian Financial Services Sector. The outcomes of this research were many, however the most notable were; 1) the development and testing of the conceptual model which were deemed to contribute to the development of theory within the discipline of Information Systems, 2) the development of a unique case study protocol that was deemed to contribute to IS research in general, 3) the derivation of a set of intermediary variables (Customer service quality, Operational efficiency, Staff and Product delivery) that was found to influence the relationship between IS investment and organisational performance and therefore extended and strengthened the conceptual model, and 4) the meta-analysis that was deemed to contribute to a better understanding of the state of the art with respect to research into this complex phenomenon.

Strategic alignment : an approach to the harmonisation of business and information systems strategiesThurlby, Bob January 1998 (has links)
Information Systems are fundamental to both the day to day operations and competitiveness of most organisations. As the rate of change in organisations continues to increase this dependency has become more critical. However methods for determining the Information Systems that an organisation needs have not moved forward to reflect these increases in organisational turbulence and new capabilities offered by Information Technology. Strategic Alignment is proposed as a new method for Information Systems Planning which recognises the dynamic role of Information Systems as an agent of change and to enable organisations to model and determine how Information Systems can be exploited to improve and transform Business Strategies. Important innovations in the method are incorporation of feedback to ensure that analysis of the interaction of the Information Systems and Business objects within the model is bidirectional. Also that the development of an Information Systems Plan is a complex process which has to be modular. This enables it to incorporate existing results and information where applicable and to deliver its results incrementally. The Strategic Alignment Method has been developed from extensive research which used the Electricity Supply Industry as the source of information because it was facing immense change after its privatisation. As a result detailed case study material is presented as well as the Strategic Alignment Methodology. Maintenance of an Information Systems Plan is also addressed. Once an Information Systems Plan is produced, its implementation can take a number of years. During this time the changes in Business Strategy and Information Systems capability will change. Strategic Alignment proposes methods that will ensure the ongoing harmonisation of the Strategies during the implementation of the plan. The practical nature of the research is reflected in the Addendum which describes the work that has been done to incorporate Strategic Alignment into ICL's services methodology and to train ICL Consultants in its use.

[en] METHODS FOR WCDMA SYSTEMS PLANNING / [pt] MÉTODOS DE PLANEJAMENTO DE SISTEMAS CELULARES WCDMAMARIANA MOSTARDEIRO 28 June 2004 (has links)
[pt] Este trabalho apresenta um estudo detalhado de técnicas de
planejamento de sistemas celulares de terceira geração
WCDMA. Primeiramente é realizado um estudo teórico do
sistema WCDMA, da estrutura da interface aérea, dos
diversos tipos de canais presentes no downlink e no uplink.
A seguir são aprentadas técnicas de planejamento de rede,
com uma análise detalhada do cálculo de enlace e do
planejamento de cobertura do sistema celular. Com base
neste estudo foram realizadas diversas simulações com o
software aberto NPSW para diferentes situações em relação a
tipos de serviço, condições de uso e carga no sistema.
Estas simulações permitiram caracterizar os efeitos dos
diversos parâmetros de entrada no desempenho do sistema.
Finalmente, é apresentado um estudo de caso de planejamento
para a região do centro do Rio de Janeiro. / [en] This work presents a detailed study of planning tecniques
for third generation WCDMA cellular systems. At first a
theoretical study of the WCDMA system is presented,
including the structure of the air interface and the
various channel types in the downlink and uplink.
Following, network planning techniques are presented, with
a detailed analysis of the link budget calculations
and the system coverage planning issues. Based on this
study, the system behaviour was simulated using the open
software NPSW for different configurations of service,
operation condition and system load. The simulations
allowed the characterization of the effect of several
parameters on the system performance. Finally, a case
study of coverage planning for downtown Rio de Janeiro is
presented.
