Full textAbstract:
Effective and efficient use of public resources has a vital importance for Turkey, as for all countries. To serve this purpose, public financial management was reformed and performance budgeting system was begun to be implemented in Turkey.
In order performance budgeting system to be properly put into practice, the system should have been well designed, regulations should have been adequately prepared and necessary information, guidance and support should be provided to the implementers.
In this study, the implementation of performance budgeting system in Turkey was investigated from the perspective of public administrations under general budget and problems in the system were identified. Comments, experiences and suggestions of administrations were obtained via questionnaires and interviews, and analyzed. Additionally, regulatory legal documents and reports of administrations prepared within the performance budgeting concept were also investigated.
In order to provide constitution of a more properly designed system and more easy and smooth implementation, to obtain a well adopted system by the implementers and to get results of better quality, proposals were put forward corresponding to the identified problems.
Integrated analytic network process with a strategic resource allocation model proposal is presented to be used in update of performance programs in the aim of minimizing the deviations from targeted performance within budget constraints. The proposed model is implemented for the Strategy Development Unit of the Undersecretariat of Treasury.

Full textAbstract:
This thesis evaluates the benefit of meshing mathematical programming and expert systems for solving capital budgeting problems, using constraint logic programming methods. A review of modelling capabilities of mathematical programs for capital budgeting, and of financial expert systems leads to defining the respective role and potential of each method, and to the proposal of a two-tiered project selection approach: project evaluation and resource allocation. With emphasis placed on a tight coupling of the two tiers, logic programming is shown to be a language of choice to implement mathematical programming within an expert system shell. Prolog has the requisite properties to deal with both logical considerations and optimization problems. Although Prolog was not primarily designed to solve optimization problems, it is shown that the backtracking mechanism of the Prolog language is powerful enough for that purpose; it liberates the programmer from having to implement tree-search programs. A generate and test program is written in Turbo-Prolog, and compared to a more sophisticated test and generate implementation that uses methods of constraint satisfaction programming. Continuous capital budgeting problems are solved in CLP(${\cal R}$), an experimental extension of Prolog that enables the solution of simultaneous algebraic constraints, as required to solve linear programs.

This study provides analysis, conclusions and recommendations to assist the Deputy Commandant (DC), Manpower and Reserve Affairs Department (M&RA) and DC, Programs and Resources Department (P&R) in structure and process decisions concerning Marine Corps Manpower budget execution. DC, M&RA is the owner of the Marine Human Resource Development Process (HRDP) and the Military Personnel Marine Corps (MPMC) appropriation sponsor, while the DC, P&R has budgetary (1517) authority for MPMC budget execution. In contrast, the Navy has both sponsorship and 1517 authority within one cell at N1. By comparing these two services' organizational factors and Planning, Programming, Budgeting, and Execution Systems (PPBES), relevant differences surface, conclusions are drawn, and recommendations offered for improvements. Recommendations include realignment of 1517 authority within MPMC execution, and the melding of the Programs and Budget Branch of Manpower Plans Division, M&RA with the Military Personnel Branch, Fiscal Division, P&R (RFM). This new office will be responsible for all facets of MPMC programming, budgeting, and execution.

Full textAbstract:
During the early 1960s, the US Department of Defense, under Secretary Robert
McNamara implemented for the first time in national government a Planning-Programming and Budgeting System (PPBS) in order to improve effectiveness
and efficiency in defence program management. McNamara sought improved
effectiveness through a formal five-year program designed to reduce costs. He
also sought efficient methods of managing joint service strategy coordination,
requirements' analysis and planning, and improved alignment between the
choice of requirements and the size and nature of the acquisition program. The
Australian Defence Organisation (ADO) and the UK Ministry of Defence later
sought to implement their own forms of PPBS. Recently, both have introduced
program management innovations that seek to achieve more reliably effective
and efficient outcomes.
The thesis has reviewed program management theory with a particular focus on
its implementation challenges relating to strategic management, program
review, personnel management and program coordination. It has sought to
answer the research problem: Which specific management designs could offer
better outcomes for Australian defence technological edge programs? The
thesis' central proposition is that the greatest opportunities for improving
defence program outcomes occur when classic PPBS concepts are
implemented within a Program Management System that incorporates Zero-
Base budgeting (ZBB), Management by Objectives (MBO), and Matrix
structural systems. All of these systems, either alone or in combination seek to
enhance program quality, scheduling, financial management and evaluation.
The research used in-depth case study research based on qualitative data found
within a selection of recent Australian National Audit Office reports, and other
public records. The central proposition is subjected to dynamic reliabilityrelated
contingency analysis and evaluation. The thesis concludes with the
proposition that if managers were to implement a contingency based integrated
mixture of the above-mentioned systems they could expect improved
technological edge program outcomes.

Full textAbstract:
O baixo custo, grande aptidão produtiva e fácil cultivo das plantas forrageiras são razões para que os pastos sejam a base da bovinocultura no Brasil, e que diversas forrageiras estejam entre as culturas mais amplamente distribuídas no país. A grande extensão territorial ocupada, no entanto faz com que as áreas pastoris estejam sujeitas a condições diversas de clima e ambiente, dificultando a estimação de sua produtividade para fins de planejamento. O sucesso dos empreendimentos agropecuários depende, cada vez mais, do desenvolvimento de ferramentas que racionalizem as intervenções gerenciais no processo produtivo, possibilitando estimar o desempenho, minimizar riscos e facilitando o planejamento do empreendimento agropecuária. Modelos matemáticos que possibilitem estimar o acúmulo de matéria seca e sua distribuição estacional são atualmente uma das grandes lacunas da zootecnia brasileira. Os objetivos deste trabalho foram modelar e implementar uma estrutura de banco de dados para experimentos de crescimento de plantas forrageiras, identificar e quantificar o efeito de atributos condicionantes do acúmulo de forragens nas condições do Brasil central e desenvolver modelos estimadores do acúmulo de forragem potencial com base em parâmetros climáticos. Foram usados seis conjuntos de dados, dois para Cynodon com cinco cultivares em dois anos em um mesmo local, um para Panicum, com cinco cultivares, em um ano e um local, e três para Brachiaria, com seis cultivares, em três anos em dois locais diferentes. Uma estrutura de banco de dados foi modelada e implementada de forma a permitir a inserção do atual conjunto de dados, e a inserção futura de novos dados. Com o banco de dados populado foram realizadas consultas de forma a se obter listagens ordenadas das taxas médias de acúmulo de forragem (TMA) e das variáveis climáticas como temperatura média (Tmed), máxima (Tmax) e mínima (Tmin), radiação global incidente (Rad) e dias julianos (DJ) para cada período de crescimento. Foram realizadas regressões lineares simples e múltiplas usando as variáveis climáticas como regressoras e taxa média diária de acúmulo como variável resposta. As análises evidenciaram alta correlação entre as variáveis climáticas no conjunto de dados analisados, ficando entre 0,81 para Tmin e Rad e 0.98 para Tmed e Tmin. Termos quadráticos para as variáveis regressoras não foram significativos (P>0,05). Dentre os modelos estudados, o simples com Tmin como variável independente se destacou apresentando os melhores valores para o coeficiente de determinação (R2), critério de informação de Akaike (AIC) e critério de informação Bayesiano (BIC) para os diferentes cultivares. Com isso, optou-se por modelos simples com a Tmin como variável preditora. Inicialmente foram gerados modelos para cada gênero, agregando os diversos cultivares. Testes de coincidência demonstraram diferença de parâmetros entre cultivares. Novos modelos foram gerados para cada cultivar individualmente, e desta vez os teste de coincidência permitiram agrupar os cultivares em B1 para Marandu, Basilisk e Arapoty (TA=-94.92+8.19Tmin); B2 para Capiporã e Xaraés (TA=-128.07+10.66Tmin); C1 para Tifton 85 e Estrela (TA=- 84.69+9.06Tmin); C2 para Coastcross, Florico e Florona (TA=-67.01+7.97Tmin); P1 para Atlas e Mombaça (TA=-55.22+6.36Tmin) e P2 para Tanzânia e Tobiatã (TA=- 29.15+5.93Tmin).Low production costs, yield potential, and ease of cultivation are three major reasons why tropical forages are the backbone of livestock production systems in Brazil. It also explains why pasture species are among the most widely grown crops in the country. The large land area of the country, make for contrasting environments, which, in turn, make it difficult for the establishment of standard management practices, as well as for the prediction of pasture productivity for planning purposes of the forage-livestock enterprise. The success of the agricultural enterprise depends increasingly on the development of tools that can support management decisions, allowing for the estimation of pasture performance, minimizing risks and facilitating planning. The lack of strong, proven mathematical models developed to estimate the forage accumulation and seasonal yield distribution are some of the shortcomings of the Brazilian pasture-bases livestock industry. The objectives of this study were to develop and implement a database on major tropical forage species, compiled from published studies, organize the datasets in standard formats, identify and quantify the constraints and major attributes related with forage accumulation in central Brazil conditions, and to propose models for estimating potential forage accumulation based on climatic variables. Five datasets were used, two on Cynodon spp. with five genotypes, grown over two years at the same location, one on Panicum spp. using five genotypes grown in one year at one location, and two on Brachiaria spp. using five genotypes grown at two locations over three years. A database structure was modeled and implemented to allow for the insertion of future data points. Whit the database completed, queries were simulated in order to check for output listings on mean herbage accumulation rates (HAR), as well as climatological variables such as low (Tmin), mean (Tmean) and high (Tmax) temperatures, incoming radiation (Rad), and day of the year (DOY), for each regrowth period. Simple and multiple regression models were tested using the climatological data as independent variables and mean herbage accumulation rate as the dependent variable, after correlation analysis showed high association between accumulation and the independent variables tested (from 0.81 for Tmin and Rad to 0.98 for Tmed and Tmin). No quadratic coefficients were significant in the regression models. The Tmin model showed the highest R2 and the best values for both the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC) across genotypes. Thus, simple models based on Tmin were selected and initially, models were generated for groups of genotypes (genera), where concidence tests showed differences among genotypes within groups. For this reason, new models were generated for each genotype individually, which resulted in the following grouping: B1 for Marandu, Basilisk and Arapoty (HAR = - 94.92 + 8.19 Tmin), B2 for Capiporã and Xaraés (HAR = -128.07 + 10.66 Tmin), C1 for Tifton 85 and stargrass (HAR = - 84.69 + 9.06 Tmin), C2 for Coastcross, Florico and Florona (HAR = - 67.01 + 7.97 Tmin), P1 for Mombaça and Atlas (HAR = - 55.22 + 6.36 Tmin), and P2 for Tanzania and Tobiatã (HAR = - 29.15 + 5.93 Tmin).

Im Zuge erster Reformbemühungen der UNESCO wurden 1977 die Mittelfristigen Strategien ("C/4-Dokumente") als sechsjährige Planungsinstrumente eingeführt. Durch ihren längerfristigen konzeptionellen Rahmen sollten sie größere Kontinuität und Kohärenz zwischen den bisher bestehenden zweijährigen Programmen und Haushaltsplänen herstellen. Die vorliegende Arbeit stellt die Entwicklung der Funktion der Mittelfristigen Strategien im Lichte ihrer historischen Entwicklung und im Zusammenspiel mit Reformtrends im System der Vereinten Nationen dar; deren Hauptfunktion ist demnach eine bessere Planung der Aktivitäten der UNESCO unter einer möglichst effizienten Mittelverwendung. Der Vorbereitungsprozess dient als Katalysator für eine umfassende Diskussion über die grundlegende Ausrichtung und über die Schwerpunkte der Aktivitäten der UNESCO. Ferner dient sie als Instrument der Legitimation und der Rechenschaft – da sie vorab darlegt, was die UNESCO in einem Zeitraum erreichen wird.

Full textAbstract:
Generation and transmission investment planning in deregulated markets faces new challenges
particularly as deregulation has introduced more uncertainty to the planning problem. Tradi-
tional planning techniques and processes cannot be applied to the deregulated planning problem
as generation investments are profit driven and competitive. Transmission investments must
facilitate generation access rather than servicing generation choices. The new investment plan-
ning environment requires the development of new planning techniques and processes that can
remain flexible as uncertainty within the system is revealed.
The optimisation technique of Stochastic Dual Dynamic Programming (SDDP) has been success-
fully used to optimise continuous stochastic dynamic planning problems such as hydrothermal
scheduling. SDDP is extended in this thesis to optimise the stochastic, dynamic, mixed integer
power system investment planning problem. The extensions to SDDP allow for optimisation of
large integer variables that represent generation and transmission investment options while still
utilising the computational benefits of SDDP. The thesis also details the development of a math-
ematical representation of a general power system investment planning problem and applies it to
a case study involving investment in New Zealand’s HVDC link. The HVDC link optimisation
problem is successfully solved using the extended SDDP algorithm and the output data of the
optimisation can be used to better understand risk associated with capital investment in power
systems.
The extended SDDP algorithm offers a new planning and optimisation technique for deregulated
power systems that provides a flexible optimal solution and informs the planner about investment
risk associated with uncertainty in the power system.

The language allows to represent AI planning problems in a declarative way and is capable of representing incomplete knowledge as well as nondeterministic effects of actions.After explaining some basics, the syntax and semantics of this language will be formally described and some results on the computational complexity of our language will be given, proving that K is capable of expressing hard planning problems, possibly involving incomplete knowledge or uncertainty, such as secure (conformant) planning.A translation from various planning tasks specified in K to a logic programming framework will be shown subsequently. We have implemented a prototype of a planning system, DLVK, on top of the disjunctive logic programming system DLV, to show the practical use of our translation. This prototype will be presented in detail. Finally, examples and experimental results will be given, together with an outlook to further research.Austrian Science Funds (FWF)

The failure rate of new government information technology (IT) projects in developing countries is high, with 35% classified as total failures and approximately 50% as partial failures. The population for this study was 10 senior managers of a public sector organization in Uganda selected because of high IT project successes achieved through leveraging IT return on investment (ROI) reports. The purpose of this qualitative single-case study was to explore the strategies Ugandan senior public sector officials used to leverage IT ROI reports during planning, budgeting, and implementation of IT projects to reduce failure rates. The conceptual frameworks were the strategic IT alignment model and framework for success. Qualitative data were collected through face-to-face interviews and review of the organization performance reports. Member checking of interview and document review data were used to strengthen credibility of the findings. The following themes emerged: involve senior managers in IT ROI reporting; use previous IT performance reports during planning, budgeting, and implementation; empower project teams to undertake IT ROI performance assessment; ensure completeness of the IT ROI reports; ensure comprehensive monitoring and evaluation indicators for IT projects; ensure availability of periodic IT ROI reports; and implement a change management program. The findings may contribute to social change by providing key strategies senior public sector officials might leverage during planning, budgeting, and implementation of IT projects to reduce failures, lead to increased citizen access to e-government services, and promote transparent government.

We compare the use of stochastic dynamic programming (SDP), Neural Networks and a simple approximation rule for calculating the real option value of a flexible production system. While SDP yields the best solution to the problem, it is computationally prohibitive for larger settings. We test two approximations of the value function and show that the results are comparable to those obtained via SDP. These methods have the advantage of a high computational performance and of no restrictions on the type of process used. Our approach is not only useful for supporting large investment decisions, but it can also be applied in the case of routine decisions like the determination of the production program when stochastic profit margins occur.

There is a significant difference between classic approach and project approach. We try to find and launch new way into the current state intuitively or to extend activities in classic approach, project approach demand clear and intelligible definition of the alternation. Advanced project management should be accustomed to complex definition of the customer need and at the same time with the cost reduction tool in production phase. Flexible planning, continuous monitoring and subsequent interpretation of particular phases of the project management is needed. Managerial accounting is able to come through with wide scale of specific tools which help and allow effectively react on daily basis, monitor development and subsequently interpret the project results.

Full textAbstract:
Water supply system planning is concerned about the design of water supply infrastructure for distributing water from sources to users. Population growth, economic development and diminishing freshwater supplies are posing growing challenges for water supply system planning in many urban areas. Besides the need to exploit alternative water sources to the conventional surface and groundwater supplies, such as reclaimed water, a systematic point of view has to be taken for the efficient management of all potential water resources, so that issues of water supply, storage, treatment and reuse are not considered separately, but rather in the context of their interactions. The focus of this dissertation is to develop mathematical models and optimization algorithms for water supply system planning, where the interaction of different system components is explicitly considered. A deterministic nonlinear programming model is proposed at first to decide pipe and pump sizes in a regional water supply system for satisfying given potable and non-potable user demands over a certain planning horizon. A branch-and-bound algorithm based on the reformulation-linearization technique is then developed for solving the model to global optimality. To handle uncertainty in the planning process, a stochastic programming (SP) model and a robust optimization (RO) model are successively proposed to deal with random water supply and demand and the risk of facility failure, respectively. Both models attempt to make the decision of building some additional treatment and recharge facilities for recycling wastewater on-the-site. While the objective of the SP model is to minimize the total system design and expected operation cost, the RO model tries to achieve a favorable trade-off between system cost and system robustness, where the system robustness is defined in terms of meeting given user demands against the worst-case failure mode. The Benders decomposition method is then applied for solving both models by exploiting their special structure.

Full textAbstract:
In this dissertation, we introduce and study robust optimization models and decomposition algorithms in order to deal with the uncertainties such as terrorist attacks, natural disasters, and uncertain demand that are becoming more and more signicant in power systems operation and planning. An optimal power grid hardening problem is presented as a defender-attacker-defender (DAD) sequential game and solved by an exact decomposition algorithm. Network topology control, which is an eective corrective measure in power systems, is then incorporated into the defender-attacker-defender model as a recourse operation for the power system operator after a terrorist attack. Computational results validate the cost-eectiveness of the novel model. In addition, a resilient distribution network planning problem (RDNP) is proposed in order to coordinate the hardening and distributed generation resource placement with the objective of minimizing the distribution system damage under uncertain natural disaster events. A multi-stage and multi-zone based uncertainty set is designed to capture the spatial and temporal dynamics of a natural disaster as an extension to the N-K worst-case network interdiction approach. Finally, a power market day-ahead generation scheduling problem, i.e., robust unit commitment (RUC) problem, that takes account of uncertain demand is analyzed. Improvements have been made in achieving a fast

Esta dissertação apresenta um aplicação de programação linear fuzzy para o problema de planejamento da expansão de redes de transmissão de potência sob considerações de incertezas. A partir da modelagem dos conceitos vagos e imprecisos, inerentes ao problema de planejamento, com a utilização da teoria da lógica fuzzy é possível incorporar as incertezas dentro do modelo do problema. Os conceitos de programação linear fuzzy são utilizados para transformar tanto a função objetivo como as restrições fuzzy em funções crisp, que podem ser tradadas por métodos tradicionais de programação matemática. Uma aplicação desta teoria é realizada utilizando uma versão modificada do sistema teste de Garver , onde as incertezas em relação a previsão de demanda futura é considerada. Os resultados obtidos mostram a capacidade da utilização dessa metodologia para metodologia para problemas de planejamento sob incertezas.
This thesis describes an application of fuzzy linear programming in power transmission network expansion planning under uncertainty. The utilization of fuzzy logic theory, considering the modeling of vagueness and imprecision (inherent in the planning problem), makes it possible to incorporate the uncertainty within the model. Fuzzy linear programming is used to transform both the objective function and constraints (Fuzzy) into crisp functions, which can be modeled by traditional methods of mathematical programming. An application of this approach is built by using a modified version of the Garver test system which also takes into account the uncertainty in the forecasted demand. The results obtained show the capability of this methodology in planning problems under uncertainty.

Full textAbstract:
A review of the normative literature, in the field of Information Technology (IT)/ Information System (IS) justification, examines how organisations evaluate their investments in Manufacturing Resource Planning (MRPII). This is achieved through investigating the issues surrounding capital budgeting, with a particular focus on investment appraisal. In doing so, a novel taxonomy of generic appraisal techniques is proposed. This taxonomy identifies a number of methods for appraising MRPII investments, and through describing these techniques, a classification is offered that identifies their respective characteristics and limitations. In doing so, it becomes clear that although many of the benefits and savings resulting from MRPII are suitable for inclusion within traditional accountancy frameworks, it is their intangible and non-financial nature, together with a range of indirect project costs that confuse the justification process. These factors, together with a range of human and organisational implications, that further complicate the decision making process are also identified. Hence, it appears through a critical review of the literature that many companies are unable to assess the implications of their MRPII investments, thus amounting to a myopic appraisal process that focuses on the analysis of those benefits and costs that are financially quantifiable. In acknowledging the limitations of traditional appraisal techniques, a conceptual model for IT/IS investment evaluation is proposed, which is underpinned by research hypotheses. To test the validity of the proposed hypotheses, a robust novel research methodology is then developed. In doing so, an interpretivist stance is adopted, which favours the use of qualitative research methods during a multiple case enquiry. Whilst conducting the empirical research, it soon emerged that the hypotheses represented significant factors for consideration within the presented model. As a result, such constructs now establish themselves as integral parts within a structured evaluation process. However, during the empirical research, complementary evaluation criteria also emerged, which resulted in modifications being made to the previously presented conceptual model. In doing so, culminating in the development of descriptive MRPII evaluation criteria and a model, which provides investment decision makers with novel frames of reference during the evaluation of MRPII investment proposals.

Cette thèse est une partie d’un projet français qui s’appelle AEROSTRIP, un partenariat entre l’Institut Pascal, Sigma, SAPPI et Air-France industries, il est financé par le gouvernement français par le programme FUI (20 eme appel). Le projet AEROSTRIP consiste à développer le premier système automatique qui nettoie écologiquement les surfaces des avions et les pièces de rechange en utilisant un abrasif écologique projeté à grande vitesse sur la surface des avions (maïs). Ma thèse consiste à optimiser les trajectoires du système robotique total de telle façon que le décapage de l’avion soit optimal. Le déplacement des robots est nécessaire pour assurer une couverture totale de la surface à décaper parce que ces surfaces sont trop grandes et elles ne peuvent pas être décapées d’une seule position. Le but de mon travail est de trouver le nombre optimal de robots avec leur positions optimales pour décaper totalement l’avion. Une fois ce nombre est déterminé, on cherche les trajectoires des robots entre ces différentes positions. Alors, pour atteindre ce but, j’ai défini un cadre général composant de quatre étapes essentiels: l’étape pre-processing, l’étape optimization algorithm, l’étape generation of the end-effector trajectories et l’étape robot scheduling, assignment and control.Dans ma thèse, j’ai deux contributions dans deux différentes étapes du cadre général: l’étape pre-processing et l’étape optimization algorithm. Le calcul de l’espace de travail du robot est nécessairedans l’étape pre-processing: on a proposé l’Analyse par Intervalles pour trouver cet espace de travail parce qu’il garantie le fait de trouver des solutions dans un temps de calcul raisonnable. Alors, ma première contribution est une nouvelle fonction d’inclusion qui réduit le pessimisme, la surestimation des solutions qui est le principal inconvénient de l’Analyse par Intervalles. La nouvelle fonction d’inclusion est évaluée sur des problèmes de satisfaction de contraintes et des problèmes d’optimisation des contraintes. En plus, on a proposé un algorithme d’optimisation hybride pour trouver le nombre optimal de robots avec leur positions optimales: c’est notre deuxième contribution qui est dans l’étape optimization algorithm. Pour évaluer l’algorithme d’optimisation, on a testé cet algorithme sur des surfaces régulières, comme un cylindre et un hémisphère, et sur un surface complexe: une voitureThis PHD is a part of a French project named AEROSTRIP, (a partnership between Pascal Institute,Sigma, SAPPI, and Air-France industries), it is funded by the French Government through the FUIProgram (20th call). The AEROSTRIP project aims at developing the first automated system thatecologically cleans the airplanes surfaces using a process of soft projection of ecological media onthe surface (corn). My PHD aims at optimizing the trajectory of the whole robotic systems in orderto optimally strip the airplane. Since a large surface can not be totally covered by a single robot base placement, repositioning of the robots is necessary to ensure a complete stripping of the surface. The goal in this work is to find the optimal number of robots with their optimal positions required to totally strip the air-plane. Once found, we search for the trajectories of the robots of the multi-robot system between those poses. Hence, we define a general framework to solve this problem having four main steps: the pre-processing step, the optimization algorithm step, the generation of the end-effector trajectories step and the robot scheduling, assignment and control step.In my thesis, I present two contributions in two different steps of the general framework: the pre-processing step, the optimization algorithm step. The computation of the robot workspace is required in the pre-processing step: we proposed Interval Analysis to find this workspace since it guarantees finding solutions in a reasonable computation time. Though, our first contribution is a new inclusion function that reduces the pessimism, the overestimation of the solution, which is the main disadvantage of Interval Analysis. The proposed inclusion function is assessed on some Constraints Satisfaction Problems and Constraints Optimization problems. Furthermore, we propose an hybrid optimization algorithm in order to find the optimal number of robots with their optimal poses: it is our second contribution in the optimization algorithm step. To assess our hybrid optimization algorithm, we test the algorithm on regular surfaces, such as a cylinder and a hemisphere, and on a complex surface: a car

Full textAbstract:
PLAS is a cloud-based software used for planning and scheduling fleets of vehicles for material transport. PLAS consists of two components; the Logistic Flow Solver (LFS) and the Material Transport Scheduler (MTS). Based on transportation requests, the LFS generates a set of logistic flows. The MTS then transforms the logistic flows into tasks that are assigned to the vehicles. The LFS is implemented with Mixed Integer Linear Programming (MILP). Currently, the LFS and the MTS are decoupled from each other and there is information that is not considered in the LFS. Thus, the choice of logistic flows generated with the current formulation may negatively impact the final transport plan. The objective of this thesis is to investigate how the generation of logistic flows can be improved. Two alternative mathematical models for the LFS were developed using MILP formulation. Compared to the current model, more information is taken into account in the two new models. Three different objective functions were considered. Scheduling of the vehicles were modelled as pickup and delivery problems, where pickup and delivery pairs correspond to the generated logistic flows. The models were implemented using Google OR-Tools, an open-source software suite for optimization. The different mathematical formulations were evaluated based on their performance for test problems with different fleet compositions. The results show that problem characteristics influence the performance of the models and that there is no model that gives the best result for every type of problem. Therefore, it is necessary to analyse problem characteristics in order to choose a suitable model for generation of logistic flows.PLAS är en molnbaserad mjukvara som används för planering och schemaläggning av fordonsflottor för materialtransport. PLAS består av två komponenter; Logistic Flow Solver (LFS) and Material Transport Scheduler (MTS). Baserat på transportbehov genererar LFS ett antal logistikflöden. MTS omvandlar sedan logistikflödena till uppdrag som är tilldelade till fordonen. LFS är implementerad med blandad heltalsprogrammering. För närvarande är LFS och MTS frikopplade från varandra och det finns information som inte tas hänsyn till i LFS. Därför kan valet av logistikflöden genererade med den nuvarande formuleringen negativt påverka den slutliga transportplanen. Målet med detta examensarbete är att undersöka hur genereringen av logistikflöden kan förbättras. Två alternativa matematiska modeller utvecklades med MILP-formulering. Jämfört med den nuvarande modellen, tar de två nya modellerna hänsyn till mer information. Tre olika målfunktioner beaktades. Modellerna implementerades med Google OR-Tools, en öppen programvara för optimering. De matematiska formuleringarna utvärderades baserat på deras prestation på testproblem med olika kompositioner av fordonsflottor. Resultaten visar att problemegenskaper påverkar modellernas prestationer och att det inte finns någon modell som ger bäst resultat för varje problemtyp. Därför är det nödvändigt att analysera problemegenskaper för att kunna välja en lämplig modell för generering av logistikflöden.

Full textAbstract:
Swedish home care industry has been facing both external and internal problems, such as ageing population, varying quality and unsatisfactory continuity. Accordingly, workforce scheduling system, as one of the most common and useful software within home care planning nowadays, is in need of constant improvement and upgrading. This master’s thesis aimed to explore and analyze improvement potential of an established workforce scheduling system for an IT-company. The thesis was divided into two phases, of which a pre-study in Phase I tried to understand the planning process for planners and identify the perceived problems and shortcomings of the current system from a planner’s perspective. Based on the analysis from the pre-study, the caregiver continuity was chosen as the research area for Phase II. The current system was re-implemented and was modelled as an optimization problem. Furthermore, the system mainly consisted of two key parts, mixed integer linear programming (MILP) and heuristics. Different approaches in terms of modifications in both MILP and heuristics were applied to the re-implemented system. The performance of the modifications was measured by multiple evaluation indicators. The test results showed that there was a potential to improve caregiver continuity with 1.2% to almost 13% depending on the modification type. The modifications were lastly suggested for further examination regarding their practical appropriateness by applying them to the current running algorithm.Den svenska hemtjänsten möter både yttre och inre problem såsom åldrande befolkning, varierande kvalitet och bristande kontinuitet. Schemaläggningssystemet som är en av de vanligaste och användbaraste programvarorna inom hemtjänsten behöver därmed en ständig förbättring och uppgradering som bemöter de existerande utmaningarna. Detta examensarbete hade som syfte att utforska och analysera förbättringspotentialen av ett etablerat schemaläggningssystem för ett ITföretag. Arbetet var indelat i två faser, varav förstudien i Fas I försökte förstå planerarnas planeringsprocesser och identifiera upplevda problem och brister i det nuvarande systemet utifrån ett planerares perspektiv. Baserat på analysen från förstudien, personalkontinuitet valdes som ett forskningsområde för Fas II. Nuvarande systemet implementerades om och det modellerades som ett optimeringsproblem. Systemet bestod huvudsakligen av två nyckeldelar, blandat heltalslinjärprogrammering (MILP) och heuristik. Olika metoder i form av modifieringar i både MILP och heuristik tillämpades på det omimplementerade systemet. Modifieringarnas prestanda mättes sedan med flera utvärderingsindikatorer. Testresultaten visade att, beroende på vilken modifiering det gäller, fanns det en potential att förbättra personalkontinuiteten med 1,2% till nästan 13%. Det föreslogs slutligen att modifieringarnas praktiska lämplighet behövs undersökas ytterligare genom att applicera det på det nuvarande systemet som är i drift.

Uppsatsen utgår från resultatet av Holmen AB:s medarbetarenkät Holmen Inblick 2011 i vilken 55 till 65 procent av cheferna uppgav att de känner sig delaktiga i mål, budget respektive verksamhetsplan. Enkätens resultat avviker från ledningens önskade utfall, vilket i uppsatsen omnämns som ett styrglapp.Studiens syfte är att analysera vad som orsakar ett styrglapp genom att klarlägga varför och till vilken grad chefer i Holmen är medvetna om, och kan påverka, mål, budget och verksamhetsplan. Genom att förstå detta kan de åtgärder som krävs för att reducera styrglappet identifieras av koncernledningen. Studien avgränsas till att analysera hur organisationens struktur, kontroll och kommunikation påverkar styrglappet.I studien används en kvalitativ intervjumetod där 17 chefer på två bruk i Holmens koncern har intervjuats individuellt. Därtill intervjuades platschefen för respektive bruk samt Holmens HR-direktör. HR-specialister har även bistått med information.Studien visade att Holmens chefer till låg grad är medvetna om innehållet i mål, budget och verksamhetsplan. Färre har möjlighet att påverka styrverktygen, där påverkan på budget är lägst. Resultatet skiljer sig mellan de två bruken. Medvetenheten och inflytandet är minst bland chefer i produktionen. Den låga delaktigheten beror på brist på formalisering kring hur arbetet med mål, verksamhetsplan och budget ska gå till. Den decentraliserade organisationens maktstruktur försämrar förutsättningarna för koncernledningen att centralt kontrollera utformningen av arbetet med styrmedlen på olika bruk. Avsaknaden av en effektiv kombination av skriftlig, muntlig och elektronisk kommunikation ökar också styrglappet.Till sist, kan enkätfrågans utformning ha haft en betydande inverkan på hur cheferna har svarat, då det saknades en definition av ordet delaktighet. Negativa enkätsvar kan också ha varit ett sätt att uttrycka missnöje över något annat.

Full textAbstract:
To be more competitive in the market, many companies are trying to speed up the quotation process and quote more attractive prices. Therefore, they have identified a need for support in the quotation process in order to reduce the quotation lead-time and ensure a higher level of accuracy in the cost estimations. The Quotation Calculator, an application program, has been developed as part of the degree thesis which was carried out at AB Norrahammars Mekaniska Verkstad, NMW 2006/07. This Quotation Calculator can be operated to calculate the material and manufacturing costs of a new product.
NMW has recently acquired licenses for CATIA V5, Dassault Systems, for the purpose of making process planning and NC-programming more efficient. NMW wants to generate the data needed from the machining module for the cost calculations. Hence this project was initiated in order to extract data from CATIA V5 for further use in Quotation Calculator or other computer system in NMW.
This work has resulted in a system developed with a common hosted programming language to extract and transfer information. The system retrieves model geometry from CAD and information on process planning from CAM, then matches the information in the application for the purpose of cost estimation. The system once developed, is supposed to be used for every new product. For this approach, the relationship of the data from CATIA V5 and the Quotation Calculator has been analyzed.
Within this thesis, the focus is on production cost estimation. The method used here is programming in Visual Basic Editor to extract information from the machining module in CATIA V5 and then import them to Microsoft Excel. With standard operations, tables of data and several inputs, the cost calculation and hence the quotation process can be automatically implemented. This work has been generated with the Quotation Calculator. With the correct input data to process planning and this new quotation system, the machining time and the costs can be estimated more accurately and easier. The time and cost information is made available for decision making. As a result, the lead time for the quotation process will be shortened and a relatively more attractive price can be quoted to the customers.

La thèse traite de la planification des mouvements optimaux dans les systèmes robotiques redondants pour l'automatisation des processus d’enroulement filamentaire. L'objectif principal est d'améliorer la productivité des cellules de travail en développant une nouvelle méthodologie d'optimisation des mouvements coordonnés du robot manipulateur, du positionneur de pièce et de l'unité d'extension de l'espace de travail. Contrairement aux travaux précédents, la méthodologie proposée offre une grande efficacité de calcul et tient compte à la fois des contraintes technologiques et des contraintes du système robotique, qui décrivent les capacités des actionneurs et s'expriment par les vitesses et accélérations maximales admissibles dans les articulations actionnées. La technique développée est basée sur la conversion du problème continu original en un problème combinatoire, où toutes les configurations possibles des composants mécaniques sont représentées sous la forme d'un graphe multicouche dirigé et le mouvement temporel optimal est généré en utilisant le principe de programmation dynamique. Ce mouvement optimal correspond au plus court chemin sur le graphique satisfaisant les contraintes de lissage. Les avantages de la méthodologie développée sont confirmés par une application industrielle d’enroulement filamentaire pour la fabrication de pièces thermoplastiques au CETIMThe thesis deals with the optimal motion planning in redundant robotic systems for automation of the composite lay-up processes. The primary goalis to improve the lay-up workcell productivity by developing a novel methodology of optimizing coordinated motions of the robotic manipulator,workpiece positioner and workspace extension unit,which ensure the shortest processing time and smooth movements of all mechanical components. In contrast to the previous works, the proposed methodology provides high computational efficiencyand also takes into account both the technological constraints and the robotic system constraints, which describe capacities of the actuators and are expressed by the maximum allowable velocities and accelerations in the actuated joints. The developed technique is based on conversion of the original continuous problem into a combinatorial one, where all possible configurations of the mechanical components are represented as a directed multi layergraph and the desired time-optimal motion is generated using dynamic programming principle for searching the shortest path on the graph satisfying the smoothness constraints. It is also proposed an enhancement of this technique by dividing the optimization procedure in two stages combining global and local searches. At the first stage, the developed algorithm is applied in the global search space generated with large discretization step. Then,the same technique is applied in the local search space, which is created with smaller step in the neighborhood of the obtained trajectory. The advantages of the developed methodology are confirmed by industrial implementation on the factory floor that deals with manufacturing of the high pressure vessel

Thesis (MBA)--Stellenbosch University, 2007.ENGLISH ABSTRACT: Diamond mining started in Kimberley in the early 1870s following the discovery of the various diamond bearing kimberlite pipes. Initial open pit mining was replaced by underground mining as the pits went deeper and the last underground mining eventually ceased in 2005 as a result of economic reasons. The mining of these primary resources created a number of tailing resources (previously called dumps) that are scattered all over Kimberley. These resources still contain diamonds as a result of historical inefficient processing technologies. However, each of these resources have unique geological and metallurgical properties because of the differences in the original kimberlites and the different treatment technologies that were used when the tailing resources were deposited. The tailing resources are mined by a fleet of earthmoving equipment and delivered to one of Kimberley Mines‟ five treatment plants for diamond recovery. Each plant is different in terms of treatment capacity, technologies utilised and overall efficiencies. These differences, combined with the geo-metallurgical properties of each individual resource and the hauling distance from the resource to the plant, determine if the specific resource can be treated profitably through that plant. With this array of resources available, Kimberley Mines is in the fortunate position of having flexibility to maximise the Net Present Value (NPV) of the operation. Unfortunately this flexibility also increases the complexity of finding the optimal solution. Mine Planning is currently conducted with a spreadsheet based input – output model but this model is not able to match the resource properties with the plant parameters and this method results in a plan that may be neither practical nor optimal. The model is also very time-consuming and scenario analyses are therefore very limited. This report presents the development of a mixed integer linear programming model to assist with the development of a practical, optimal mine plan. The model is roughly based on a generic model that addresses facility location and processing plant problems as developed by Barbaro & Ramani (1986); however, the model presented in this report includes a more detailed mass balance within the plant and models how the metallurgical properties of the resources affect the mass balances and overall throughputs. The results of the project indicate that the current spreadsheet based Mine Plan is not practical since it violates two mass balance constraints within the Combined Treatment Plant. The newly developed system is used to generate a mining schedule that does not violate any constraints while still delivering the same net present value and overall throughput. The system also illustrates that the plant can improve the annual throughput by 18.2% by changing one screen size. The system also illustrates that only two of the five plants add value and supports management‟s recent decision that the production through the other plants should cease. In summary: The newly developed system generates an optimal, practical mine plan in less than a tenth of the time required for the old spreadsheet based model. The new system can also do various what-if scenarios which the previous model could not answer.
AFRIKAANSE OPSOMMING: Die ontginning van diamante in Kimberley het in die vroeë 1870s begin na die ontdekking van verskeie diamanthoudende kimberlietpype. Aanvanklike oopgroefmynbou is later vervang deur ondergrondse metodes soos die myne dieper geword het. Die laaste ondergrondse myne het in 2005 produksie gestaak as gevolg van ekonomiese redes. Die ontginning van hierdie primêre reserwes het gelei tot die ontstaan van verskeie uitskotreserwes (voorheen genoem afvalhope) verspreid oor Kimberley. Hierdie reserwes bevat steeds diamante as gevolg van die historiese oneffektiewe aanlegte. Die reserwes het elkeen egter verskillende geologiese en metallurgiese eienskappe as gevolg van die verskille in die oorspronklike kimberliete en die verskillende herwinningstegnologieë wat in gebruik was toe die uitskotreserwes gegenereer is. Die uitskotreserwes word gemyn deur ‟n vloot grondverskuiwingstoerusting en word afgelewer by een van Kimberley Myne se vyf aanlegte vir diamantherwinning. Elke aanleg is uniek in terme van kapasiteit, tegnologieë in gebruik en algehele effektiwiteit. Hierdie verskille, tesame met die geo-metallurgiese eienskappe van elke reserwe en die vervoerafstand van die reserwe na die aanleg bepaal of die spesifieke reserwe winsgewend deur daardie aanleg geprosesseer kan word. Bogenoemde verskeidenheid van hulpbronne gee aan Kimberley Myne die voordeel van buigsaamheid om die Netto Huidige Waarde (NHW) van die myn te maksimeer. Hierdie buigsaamheid vergroot egter die kompleksiteit om die optimale antwoord te vind. Beplanning word tans met ‟n sigblad gebasseerde invoer – uitvoer model gedoen, maar hierdie model is nie in staat om die reserwes se eienskappe by die aanlegte se parameters aan te pas nie. Hierdie metode genereer dus ‟n plan wat moontlik nie prakties of optimaal is nie. Die model is ook tydrowend en scenario analises is dus baie beperk. Hierdie verslag beskryf die ontwikkeling van ‟n gemengde heeltallige lineêre programmeringsmodel vir die ontwikkeling van ‟n praktiese, optimale produksieplan. Die model is losweg gegrond op ‟n generiese model van Barbaro & Ramani (1986) wat fasiliteit posisionering en aanlegprobleme aanspreek. Die model in hierdie verslag bevat egter ‟n meer gedetailleerde massabalans binne die aanleg en modelleer hoe die metallurgiese eienskappe van die reserwes die massabalanse en die algehele kapasiteite beïnvloed. Die resultate van die projek dui daarop dat die huidige sigblad produksieplan nie prakties is nie aangesien dit twee massabalansbeperkings in die Combined Treatment Plant oorskry. Die nuwe stelsel is gebruik om ‟n produksieskedule te genereer wat nie enige beperkings verbreek nie en wat terselfdertyd die aanvanklike netto huidige waarde en totale produksie ewenaar. Die stelsel wys ook dat die jaarlikse kapasiteit met 18.2% verhoog kan word deur een van die sif-groottes te verander. Die stelsel demonstreer ook dat slegs twee van die vyf aanlegte waarde toevoeg en ondersteun bestuur se onlangse besluit dat die produksie deur die ander aanlegte gestaak behoort te word. Ter samevatting: Die nuwe stelsel genereer ‟n optimale, praktiese produksieplan in minder as ‟n tiende van die tyd benodig vir die ou sigblad model. Die nuwe stelsel kan ook verskeie “Wat sal gebeur indien…” scenario‟s hanteer wat die vorige model nie kon beantwoord nie.

According to the findings of the Global Entrepreneurship Monitor, in 2003, South Africa ranked 22nd out of 31 countries for new entrepreneurial activities. One of the greatest challenges for South Africa, is to find a solution for its huge unemployment problem, which is responsible for many of South Africa's other problems, like poverty, crime and brutality, which discourage global investment in South Africa. The development of small-, medium-, and microenterprises
(SMMEs) is seen as an important ingredient of economic development. The population for this study is therefore comprised of SMMEs in South Africa. Any enterprise is dependent on the environment it operates in. The environment consists of the macro-environment, which includes the demographic, technological, economical, social, institutional and international environment, the market environment, which includes consumers, suppliers and competitors, as well as the micro-environment, which includes the organisation, its mission, goals and objectives, management functions, business functions and business resources. The objective of this study is to investigate the possibility of applying cost- and management accounting methods and techniques for the development and profitable running of SMMEs. These include choosing an appropriate costing system, implementing a management information system, effectively executing the management functions of planning, organising, coordination and control, through the application of cost- and management accounting methods and techniques, including forecasting, budgeting, accurate and appropriate costing methods, performance management techniques like total quality management, benchmarking etcetera. Data on the current use of cost-and management accounting by SMMEs in South Africa, and the performance of these concerns, were collected by means of a structured questionnaire from a sample of 37 SMMEs. It was found, that although several cost- and management accounting methods and techniques are used by some SMMEs, many are not used effectively, while many SMMEs are not aware of the many advantages that the application of these methods and techniques hold. It is recommended that entrepreneurs make an effort to gain the knowledge needed for them to apply the cost- and management accounting methods and techniques that will improve the performance of their businesses, ensuring the attainment of their goals and objectives, ensuring their survival and prosperity, and leading to job creation, economic growth, and the prosperity of the people of South Africa. To assist with this, the researcher has developed a model and a manual that can be used by entrepreneurs to assist them in starting a new enterprise, as well as running a successful enterprise.Thesis (Ph.D. (Business and Management Accounting))--North-West University, Vaal Triangle Campus, 2009.

To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users. The process industry sector is one of the largest users of energy, and thus important to analyse. Process industries are also capital intensive and operate on large and expensive process equipment, making it imperative to plan their production well in order to reach preferable capacity utilisation. Therefore this dissertation strives to locate the most important energy management issues for the long term profitability of process industries, and investigates the symbiotic effects of including energy issues in production and supply chain planning. Three different studies at three case companies are carried out, analysed, and presented in five papers. The cases represent the process industry sectors: chemicals, pulp, and steel. Both qualitative case study methodologies as well as quantitative mathematical modelling and optimisation approaches have been practiced. The research questions are analysed from both an energy system and from a production process point of view, separately as well as combined. Energy is somewhat considered to be the main workforce for process industries and this dissertation exemplifies some of its most important dimensions in this context. Several prerequisites for putting energy management on the strategic agenda are located in a specialty chemical industry where the importance of introducing a strategic perspective on energy, the way energy is used, and the possibilities of increasing alternative revenue from utilising by- and/or co-products differently are pinpointed. Approaches for including energy issues in planning processes are also suggested in terms of a MILP model for the entire supply chain of a pulp company, including decisions on purchase and transportation of raw maerials, production allocation, energy mix, and distribution. Another example is presented based on the perspectives of economics of scale and lot sizing through economic order quantity principles in a steel company. By using real company data, energy smart approaches in planning and scheduling are developed with respect to the most important intersections between the production processes and their supporting energy system. The accumulated resource intensity and embedded energy could, and probably should, hence be more fairly reflected in the product price. The research finally shows some possible impact with including energy issues in a production and supply chain planning model. By planning differently, production prioritisations can be done, and it is not only possible without any large investments, but also prosperous with savings on both energy and money within reach. To conclude, planning of production and supply chain has either a direct or an indirect impact on the energy cost-effectiveness of a company. This dissertation argues that such impact also exists in its mutual form, and is very important when the energy issues are large enough, as they often are in the energy intensive process industry sector. Decision makers should thus beware of the short end of the stick that might be devastating in the long run, but also aware of all the possibilities that can bring success and prosperity when the future begins.

Este trabalho tem por objetivo apresentar uma metodologia para localização e proposição de reforços no sistema de distribuição de energia elétrica através de programação linear, PL, e algoritmo genético, AG. A técnica de PL utilizada para a localização de pontos de reforços e, principalmente, novas subestações de distribuição, é baseada no algoritmo de ?out-of-kilter?, um conhecido algoritmo de transporte. A seleção de melhores alternativas é solucionada através do AG, que permite a modelagem de redes com proporções reais e possibilita a obtenção de resultados em tempos de execução compatíveis para aplicação de atividades em planejamento de sistemas de distribuição de energia. O modelo de algoritmo proposto aloca automaticamente novos reforços, como o recondutoramento de trechos da rede e a expansão de subestações existentes, complementando os reforços candidatos, novas subestações e novos alimentadores, propostos previamente pelo modelo de PL. A metodologia proposta é aplicada à resolução de uma rede de distribuição real, possibilitando a análise da potencialidade que esta modelagem pode oferecer.This dissertation presents a methodology for the allocation and proposal of new reinforcements in electric distribution systems through linear programming (LP) and genetic algorithm (GA). The linear programming technique used for the allocation of new reinforcements, namely new distribution substation locations, is based on the ?out-of-kilter? algorithm, a well known transport algorithm. The selection of alternatives, determined by technical and economical criteria, is carried out through a genetic algorithm that allows the modeling of real sized distribution networks and makes possible the attainment of results in compatible execution times for distribution network planning. The proposed model places new reinforcements automatically, as it is the case of cable resizing in distribution lines and the expansion of existing substations, complementing the new substations and new feeders proposed by the linear programming model. The proposed methodology is applied to the solution of a real distribution network, showing the potential applications of the models.
