Texto completoFrågeställning: Hur ska artiklar till lagret köpas in och klassificeras i en ny inköpsstrategi med målet att minska lagerkostnaderna och minimera lagernivåerna till givna förutsättningar. Syfte: Syftet är att ta fram en inköpspolicy som ska minimera årliga kapitalbindningen i lagret. Metod: Inköpspolicyn är utvecklad med hjälp av en blandad metod med fokus på den kvantitativa sekundärdatan med små delar av den kvalitativa primärdatan. Beräkningsmodellen består av de lagerstyrningsformler som presenteras i teorin. Med grunden från teorin och inläggen från intervjuer har forskningsmetoden varit deduktiv och följt riktlinjerna från Ali och Birley (1999). ABB Capacitors är fallstudien för detta examensarbete som modellen har blivit testat och verifierad hos. Slutsats: Examensarbetet resulterade i inköpspolicy som består av en beräkningsmodell och en artikelanalys som har visat sig framgångsrik från de teoretiska jämförelserna och det visar på att inköpsstrategin fungerar som tänkt. Matematiska modeller är bara verktyg i en inköpsstrategi, erfarenhet och kunnande är två komponenter vars betydelse inte ska förminskas. Svagheter i modellen rör kapaciteten i lagret eftersom modellens syfte är att minimera årliga lagerkostnaden genom att köpa in ur en ekonomisk synvinkel. Det finns en risk att den fysiska lagerytan tillåter mindre kvantiteter än vad som är optimalt. Modellen rekommenderas för tillverkande industrier.

Texto completoThis thesis analyze the conduct of monetary policy in the presence of uncertainty. By adopting the framework proposed by Hansen and Sargent (2003), we analyze the behaviors of monetary authorities and private agents when faced with various sources of uncertainty, as well as their consequences in terms of macroeconomic performances. Our work shows that, in order to guard against the possibly catastrophic results of the worst-case scenario, central bankers have to react in an active manner, by manipulating the interest rate. However, in an open economy, the magnitude of this adjustment decreases with the degree of openness. Also, greater transparency of the central bank's objectives, by reducing preference uncertainty, will attenuate the variations of macroeconomic variables that follow the consideration of possible erroneous specifications. It is thus advisable to reveal informations about the central bankers' preferences, including their own estimates of the degree of model uncertainty

Texto completoThere are always painful tradeoffs in environmental problems. In the current period, the tradeoff. has to be made between consuming environmental goods and "dirty" goods. Since many pollutants accumulate in nature and cause long time problems, the current period's decision also has important impacts on future generations. This yields another tradeoff. between control of the pollution flow and cleanup of the pollution stock in the future. For a local government, tradeoffs between strict environmental policies and local economic prosperity are also concerns.
This thesis analyzes the tradeoffs made by households, firms and government under different policy regimes. Chapter 2 considers assigning tradable permits to households that are suffering from pollution generated by firms. The households can sell a limited number of permits to polluters according to personal preferences for environmental goods and "dirty" goods. It is shown that, the market transaction between households and polluters can achieve the efficient pollution level. Chapter 3 considers a case in which the stock pollution is reversible with capital investment. In a natural resource extraction model with externalities of heavy metal pollution in the surrounding farmland, the firms tradeoff. between controlling the pollution flow and abating the pollution stock, as well as the firms extraction decisions are analyzed. Chapter 4 derives the optimal environmental bond required by a local government as a financial assurance for inducing firms to do pollution abatement. A local government needs to make tradeoffs between charging a large amount of bond and encouraging local economic prosperity. For a local government, the optimal bond amount does not necessarily cover the worst-case scenario. This thesis contributes to environmental policy design by considering the interests of different parties.

The thesis that follows is an attempt to gain a deeper understanding of intellectual property from a policy as well as a strategic perspective. While the discussion that follows is applicable to intellectual property in general, the focus of this thesis is on a particular aspect of intellectual property i.e patents. Policy and strategic perspectives are covered in section I and 11 respectively. The section on policy explores the origin and evolution of intellectual property related policies by discussing key legislation and court cases. The two questions that were most relevant when exploring the policy side of the patent system were: -- Is the intellectual property system hindering or encouraging innovation? -- What changes, if any, are required to make the system more effective? The section on strategy looks at IP strategies (or lack thereof) of three leading companies, Apple, Google and Microsoft. These three companies were selected because of their apparently differing strategies and this cursory judgement was confirmed when the strategies of the companies were put under a microscope. The question that were central while exploring the strategic aspects of intellectual property were: -- How are these three companies coping with the patent system as it exists today? -- What changes can make the strategies employed more effective? The summary section at the end tries to reconcile these two different ways of looking at the intellectual property system into a coherent whole.

There is a growing realization that stakeholder involvement in decision-making for large- scale engineering systems is necessary and crucial, both from an ethical perspective, as well as for improving the chances of success for an engineering systems project. Traditionally however, stakeholders have only been involved after decision-makers and experts have completed the initial decision-making process with little or no input from stakeholders. This has resulted in conflict and delays for engineering systems with brilliant technical designs that do not address the larger context of the broader social goals. One of the fears of experts is that the involvement of stakeholders will result in technical solutions that are of poor quality. The hypothesis of this research is that an effective involvement of stakeholders in the decision-making process for engineering systems from the problem definition stage through the system representation can produce a system representation that is superior to representations produced in an expert-centered process. This dissertation proposes a Stakeholder-Assisted Modeling and Policy Design (SAM-PD) process for effectively involving stakeholders in engineering systems with wide-ranging social and environmental impact. The SAM-PD process is designed based on insights from existing engineering systems methodologies and alternative dispute resolution literature. Starting with a comprehensive analysis of engineering systems methodologies, the role of experts in engineering systems decision-making and existing stakeholder involvement mechanisms, this research explores the role of cognitive biases of engineering systems representation through actual experiments,
(cont.) and concludes that the process of defining a system through its boundaries, components and linkages is quite subjective, and prone to implicit value judgments of those participating in the system representation process. Therefore to account for stakeholder interests, concerns and knowledge in engineering systems decision-making, it is important to have a collaborative process that enables stakeholders to jointly shape the problem definition and model outputs necessary for decision-making. Based on insights from the literature, this research developed a collaborative process for engineering systems decision-making, and explored its merits and drawbacks in applying it to the Cape Wind offshore wind energy project involving actual stakeholders in the system representation process. It further explored the potential application of such a process to the Mexico City transportation/air pollution system and the Cape and Islands Renewable Energy Planning project. The Cape Wind case study showed that a stakeholder-assisted system representation was superior to the equivalent expert-centered system representation used by the permitting agency as a basis for decision-making, in that it served as a thought expander for stakeholders, captured some effects that the expert-centered representation could not capture, better took into account social, economic and political feasibility and was more useful in suggesting better alternative strategies for the system. The case studies also highlighted the importance of the convening organization, institutional readiness for collaborative processes, the importance of stakeholder selection and process facilitation, the potentials of system representation as a basis for stakeholder dialogue and the importance of quantification versus evaluation of system representations.
(cont.) The basic implication of this research is that it would be myopic of engineering systems professionals to shift the burden of stakeholder involvement to decision-makers, and keep the analysis a merely expert-centered process. Due to the many subjective choices that have to be made with regards to system boundaries, choice of components, inclusion of linkages, nature of outputs and performance metrics and assumptions about data and relationships, system analysts are in fact not producing the analysis that will help the decision-making process. The best airport designs done with multi-tradeoff analysis and intricate options analysis may lead to nowhere if stakeholders affected by the project do not see their interests reflected in the analysis. The notion is that a good systems analysis is not one that impresses other engineering systems professionals with its complexity, but one that can actually address the problems at hand.

The space industry is currently at a significant inflection point. New economies are forming in low- Earth orbit (LEO), driven by miniaturization of technologies and the promise of lower launch costs, which should then allow many of these LEO systems to capitalize on designs incorporating smaller, shorter-lived spacecraft in highly-disaggregated constellations. Meanwhile, many spacecraft at geosynchronous orbit are continuing along a trend towards increasingly massive and longer-lasting satellites, and while they do represent some of the most exquisite, highest-performing satellites ever launched, some experts now feel that such trends are unsustainable and are beginning to place increasing strain on the underlying industry. To support current and future spacecraft, orbital infrastructures have been proposed as a means of providing on-orbit services to customer spacecraft and guiding space architectures towards more sustainable paradigms. In LEO, an infrastructure of communications and data relay spacecraft is envisioned as a means of aiding new and existing space enterprises in the areas of satellite connectivity and downlink capability. Meanwhile, an on-orbit servicing (OOS) infrastructure, located primarily in geosynchronous orbit, would provide services such as repair, rescue, refueling, and upgrading of customer spacecraft, in order to alleviate the identified space industry trends. Physics and cost modeling, as well as tradespace exploration, are used to identify optimal LEO infrastructure designs, while system dynamics modeling is used to assess the trends likely to occur in the overall space industry as OOS is incorporated into space architectures. The primary conclusion from the analysis of LEO infrastructure designs is that, when designing for global connectivity, there is an optimal design point between a small constellation of larger spacecraft and a very large constellation of small spacecraft, but this will also depend on the intended mission of the infrastructure and the number of customers expecting to be serviced. Then, for an OOS infrastructure, it is determined that relatively low costs and heavy incorporation of servicing capabilities into customer architectures are needed to ensure long-term sustainability of such a project. Finally, the policy implications for both infrastructure concepts are discussed, with a heavy focus on options for the funding and development regimes employed to implement the infrastructures, as well as the major political and legal implications expected to accompany these projects.

Extravehicular activity (EVA), or spacewalks allows astronauts to accomplish some of the most important endeavors in space history. The importance of EVA will continue to increase as people venture further into our solar system. The spacesuit, used to protect the astronaut during EVA, is an anthropomorphic spacecraft that provides the physical environment a person needs to survive in the harsh environment of space. Although the suits are safe and effective, the pressurized suit becomes rigid in the vacuum of space, causing the astronaut to waste energy. Mechanical counterpressure (MCP) suits offer an alternative to gas pressurized suits by using elastic garments to provide pressure against the skin. Despite their many advantages, MCP suits are very difficult to put on, or don, making them infeasible for use today. A network of gas pressurized tubes is proposed as a solution to the donning problem. When pressurized, the tubes expand to become rigid, opening the MCP garment in the process. The system was modeled and a functional prototype was developed using a novel construction process. The model can be used as a design tool for future designs and the prototype serves as a proof-of-concept for this solution to the donning problem. The spectacular feats accomplish through spacewalks and space exploration inspire students to pursue an interest and career in science, technology, engineering, and math (STEM). Since its inception, the National Aeronautics and Space Administration (NASA) has been dedicated to educating the public about its compelling mission, fascinating discoveries, and the complicated technologies it develops. However, as the United States slips in indicators of student performance in STEM subjects, many look toward informal education, or education that occurs outside the classroom, to spur interest in STEM subjects. To maximize educational outcomes, NASA has developed a strategic framework to guide its educational programs. This framework is analyzed in the context of strategic management literature and suggests that the framework could be more easily implemented if NASA were to refine its education structure using the strengths of each of its directorates. The proposed framework was implemented in an informal education project and evaluated to determine if a projects implemented under the framework achieves the intended learning objectives. Students showed an increased understanding of NASA's mission and the complicated nature of space exploration. Suggestions to improve future projects are also given.

Texto completoLas redes de hoy en día presentan un gran crecimiento, una alta complejidad de gestión y los nuevos servicios tienen requerimientos cada vez más estrictos. Es por ello que las plataformas de gestión de la década pasada resultan inadecuadas en los nuevos escenarios de red. Esta Tesis es una contribución a los nuevos esquemas de gestión para redes de gran escala, en especial es una contribución a los sistemas de gestión basados en políticas, sin perder por ello, la compatibilidad con los sistemas de gestión que se ocupan actualmente como por ejemplo SNMP, la gestión basada en agentes, etc.
Las investigaciones relacionadas hasta ahora con los sistemas de gestión basados en políticas se enfocan principalmente en la gestión de recursos locales y en el control de admisión. La Tesis que se sustenta en este trabajo ofrece una perspectiva de la utilización de las políticas en un contexto más amplio, se propone una arquitectura para la gestión de red utilizando directorios y roles de políticas, analizando las políticas desde su fase de diseño hasta su configuración en los elementos físicos de la red
Se considera que la creación de políticas pueden llevarla a cabo diferentes entidades, por ejemplo cuando las crea el administrador de la red, cuando los propios usuarios crean sus políticas (políticas personalizadas), o bien cuando la red basándose en un conjunto de políticas previamente definidas crea a partir de ellas nuevas políticas (metapolíticas).
En esta Tesis la representación de las políticas de alto nivel se basa en los modelos propuestos por el IETF y DMTF, el Policy Core Information Model (PCIM) y sus extensiones (PCIMe). Se propone un esquema de clases orientadas a objetos para el almacenamiento de las políticas en un directorio LDAP (Lightweight Directory Access Protocol). Este esquema es una de las contribuciones que está Tesis realiza, la cual se ve reflejada en un draft realizado en conjunción con el grupo de trabajo de políticas del IETF.
Debido a que no es posible implementar directamente las políticas de alto nivel en los elementos físicos de la red es necesario establecer un conjunto de parámetros de configuración de red que definan la política que debe aplicarse. Para resolver este mapeo se crearon perfiles SLS (Service Level Specification) basados en la especificación de nivel de servicio que el usuario acuerda con el proveedor de servicio Internet. En la implementación realizada se decidió utilizar cuatro perfiles, sin embargo la granularidad que se elija en la creación de perfiles SLS se deja abierta para que el administrador de la red cree los perfiles necesarios de acuerdo con las características topológicas de la red, los objetivos empresariales, etc.
El directorio LDAP que se utiliza como repositorio de políticas almacena cientos o miles de políticas que son necesarias para resolver las diferentes tareas de gestión involucradas en un sistema de redes heterogéneas, esto puede afectar la ejecución del sistema, por lo tanto, se diseñaron métodos basados en roles de políticas para seleccionar la política o el conjunto de políticas adecuado que debe implementarse en la red en un momento especifico.
Para resolver los conflictos que puedan ocurrir entre las políticas seleccionadas y evitar inconsistencias en la red, se crearon diversos módulos para la prevención y resolución de conflictos entre políticas. El primer proceso interviene en la creación de las políticas detectando conflictos sintácticos, es decir, se analiza que la política este correctamente diseñada y que pueda ser interpretada sin problemas por la red, posteriormente se verifica que la política pueda implementarse en los elementos de la topología de red que se utilice y que cubra los objetivos empresariales existentes.
Para el caso de conflictos que puedan ocurrir en tiempo de ejecución se diseñó un método basado en espacios hiper-geométricos que permiten identificar un conflicto potencial e indicar la política adecuada que debe implementarse en la red. Dicho método está basado en una serie de métricas propuestas para definir cada servicio. Se realiza en la Tesis una aplicación de dicho método para el encaminamiento basado en restricciones de Calidad de Servicio en una red con Servicios Diferenciados y MPLS.
In today's telecommunications world the networks offer several new services involving higher and higher requirements, it means an increment of management complexity that cannot be adequately solved with the management platforms of previous years. This thesis is a contribution to new management schemes for big-scale networks; especially it is a set of contributions to the Policy-Based Management Systems (PBMS) without loosing compatibility with the current management systems such as SNMP, agent-based management, etc.
Current research mainly proposes the use of policies to configure network local devices and admission control. This thesis works on a wide perspective about the use of policies. An efficiently architecture for network management on the basis of directories and policy roles is proposed, also there is a full analysis of policies from its design to its implementation in the network elements.
The creation of policies can be carried out by different entities, for example network administrators, users (personalized policies) and when the network itself creates own policies based on a previous set of policies (metapolicies).
In this thesis the representation of high-level policies is based on the Policy Core Information Model (PCIM) and their extensions (PCIMe) from the DMTF and the IETF. Policies are stored in a directory using the Lightweight Directory Access Protocol (LDAP) via an object oriented classes model designed in this thesis. These results led to an Internet draft for the policy-working group of the IETF.
Because of direct implementation of high-level policies in the network elements it is not possible, it is necessary to establish a set of configuration parameters that define the policy that has to be enforced in the network. The methodology to map high-level policies to low-level policies is detailed in this thesis. Mapping processes involve the use of policy roles and profiles that come from Service Level Specifications (SLS) that users agree with the network. The implementation of the management system uses four SLS profiles but it is scalable to allow increasing profiles according to different aspects such as new services offered by the network, topology of the network, business goals, etc.
The policy architecture manages heterogeneous interconnected networks, for this reason policy repositories have to be able of storing hundreds or thousands of policies in order to get the desired behavior in the entire network. Due to the fact that policy decision points have to choose adequate policies to apply in the network from a very big set of policies, the network performance could be affected. This thesis proposes an efficient selection and evaluation process on the basis of both, policy roles and the network status in a specific time.
To solve possible conflicts that can occur between selected policies and avoid system inconsistencies, a set of models for the prevention and resolution of conflicts between policies is proposed. Prevention process has an algorithm to avoid syntactic conflicts and edition of new policies that produce potential conflicts with previous defined policies. Prevention process also considers congruency among policies, business goals and network topology.
Conflict resolution process solves conflicts occurring during the performance of the system, this method is based on hyper geometrical spaces and policy roles to select the adequate policy, from the conflicting policies.
These methods are presented in the Thesis with an application in a routing system with Quality of Service (QoS) restrictions into a network scenario based on Differentiated Services and the Multi Protocol Label Switching (MPLS).

Texto completoThe modern internet and phone networks offer very little security, privacy, or accountability to their users. As people conduct their business and social lives online and over the phone, they naturally generate private or sensitive data about themselves. But any number of parties can and do track this data. Not only the services people interact with everyday, but third-party services for ad tracking, malicious hackers, government agencies operating with nebulous legal authority, and service providers themselves can and do observe and track users. They can then use the sensitive data in a variety of objectionable ways.
Changing this state of affairs without an earth-shattering technological breakthrough may appear to be a hopeless situation. But, in this dissertation, we demonstrate how existing technology can, if deployed and used properly, markedly improve privacy for users and accountability for those collecting data. We discuss two techniques for achieving these improvements: privacy-preserving surveillance and anonymous communication. For each technique, we present example protocols for which we have implemented fast prototypes running on commercial hardware.
First, we define the notion of privacy-preserving surveillance. Currently, a government agency can collect and examine bulk user data while making no distinction between the legitimate target of investigation and the average person, and with little or no oversight from other agencies. Privacy-preserving surveillance is an alternative legal regime in which searches of sensitive user data could only take place with the active collaboration of multiple government agencies. Trust is distributed amongst these agencies, assuring that no single authority can unilaterally view sensitive user data (or metadata). We then show how two types of bulk surveillance, currently in use by the authorities, could be made privacy-preserving by the adoption of modern cryptographic protocols to secure data.
We also discuss protocols for anonymous communication. We take two approaches to anonymity. First, we present an improvement to the Tor network, an anonymity substrate based on onion routing that is already deployed in the wild. Second, we present a complete specification of the dining-cryptographers-based Verdict protocol arid formally prove its anonymity, security, and accountability properties.

One of the major challenges in supply chain management is the level of information availability. It is very hard yet important to coordinate each stage in the supply chain when the information is not centralized and the demand is uncertain. In this thesis, I analyzed the bullwhip effect in supply chain management using the MIT Beer Distribution Game. I also proposed heuristics and models to optimize the MIT Beer Distribution Game order policy when the customer's demand is both known and unknown. The proposed model provides each player with an order policy based on how many weeks of inventory the player needs to keep ahead to minimize the global cost of the supply chain. The optimized order policy is robust, practical, and generated by numerical simulations. The model is applied in a number of experiments involving deterministic and random demand and lead time. The simulation results of my work are compared with two other artificial agent algorithms, and the improvements brought by my results are presented and analyzed.
