A Collaboration in Product Service System for Telecom Networks : An "Orange and Ericsson case" studyDesai, Avni, Widgren, Maria January 2015 (has links)
The purpose of the research is to study the “Orange and Ericsson case” while developing the method Actors and System Map. The interaction between actors within Ericsson’s Device Connection Platform is investigated in order to identify improvement opportunities in the interaction between the provider and the customer. To answer the purpose the following research questions was formulated: RQ1) What type of actors may be involved in a telecom related IPSO? RQ2) How can the connections between actors in the telecom related IPSO be illustrated? RQ3) How can the Actors and System Map method be refined? In order to answer the research questions different methodologies were used for the analysing process. The research started with a widespread literature study to collect knowledge related to the area of Product Service System (PSS) and methodologies for identifying how actors interact with one another. Studying different mapping methods the conclusion was made that Actors and System Map was most suitable for this study. In the methodology background the previous selected method, Actors and System Map from an Integrated Product Service Offering (IPSO) perspective, was examined in order to be able to refine and improve the mapping method. Actors Map provides a visual and clear overview of the actors involved while a System Map shows the information flows and activities between the actors. To understand the interaction between the two companies, the definition of IPSO and the importance of value-based selling for a service offering are described in the theory background. Also, different ways of looking at a business model within the telecommunication industry is presented. Obtaining information regarding making an Actors Map and a System Map an improved mapping method was refined. The adaption of the method was divided into eight steps. The refined Actors Maps of the DCP shows the actors involved, how they are connected and their main assignments from each respondent’s point of view at Ericsson. The refined System Map shows what kind of information is transferred between the actors within the companies and between Orange and Ericsson. Both maps delivered as a decision basis will help identification of non-value giving links and non-optimal distances in the information flow for both companies.

Participation de parcs de production éolienne au réglage de la tension et de la puissance réactive dans les réseaux électriques / Wind farms participation at voltage and reactive power regulation in the power system networkAhmidi, Amir 16 December 2010 (has links)
Nous proposons dans cette thèse, différents outils de réglage de tension et de gestion de la puissance réactive en fonction des conditions de raccordement des éoliennes au réseau électrique. Trois cas figure sont étudiés : raccordement direct sur un poste source de distribution, raccordement des éoliennes réparties dans un réseau de distribution et raccordement d’un ensemble de parcs éoliens au réseau de transport.Un algorithme de réglage basé sur l’asservissement de la puissance réactive est proposé pour le raccordement direct d'un parc sur un poste source. Un réglage coordonné de tension en présence de régleur en charge est proposé (D-RCT) pour le raccordement des éoliennes reparties dans un réseau de distribution. On propose aussi une version plus décentralisée du réglage coordonné (D2-RCT) qui pourrait être implantée sous forme de système multi-agents intelligents (SMA). Un system de control multi-niveaux est proposé pour le raccordement d’un ensemble de parcs éoliens au réseau de transport. Il permet de répondre de manière optimale à une demande puissance réactive envoyée par le gestionnaire du réseau de transport. Les différents types de réglages proposés sont basés sur des algorithmes d’optimisation multi-objectifs. Afin de valider en temps réel le bon fonctionnement des stratégies de réglages développées ainsi que leurs modes de communication, une implantation expérimentale sous simulateur temps réel RT-Lab a été effectuée. Enfin, les résultats des simulations montrent l’amélioration de l’intégration de la production décentralisée dans les réseaux électriques / In this PhD dissertation, we propose various voltage and reactive power regulation algorithms for different connection types of the wind farm to the power network. Three connection types are considered here: a wind farm connected directly to the distribution network, dispersed wind turbines connected to the distribution network and a set of wind farms connected to the transmission system.A closed loop controller (Wind Farm Controller) is proposed in case of a directly connected wind farm to the distribution network.A coordinated voltage control in the presence of on load tap changer (D-CVC) is proposed in case of dispersed wind turbines connected to the distribution network. We also propose a more decentralized version of D-CVC named D2-CVC; this version can be also implemented under multi-agent system (MAS).A multi-level control system is proposed in case of a set of wind farms connected to the transmission system. It allows the wind farms to optimally participate at reactive power balancing in transmission network. All the proposed voltage algorithms are based on a multi-objective optimization function. The experimental implementation of these regulation algorithms is run under RT-Lab real-time simulator. It allows validating their real-time operation and their communication modes before the implementation on a real site.The results of the current thesis show the improvement of distributed generation integration in the power system network

Encouraging Recycling in Co-living : A Redesigning of Sorting Bins / Underlättning av återvinning i kollektiv bosättning : En ny design av källsorteringskärlChan, Eugene, Karuppasamy, Avinash Kumar January 2023 (has links)
There is an inefficiency of waste management in co-living spaces for students, emphasizing the importance of proper waste sorting. A multifaceted research methodology was initiated with a literature review to understand existing waste management solutions and how they work as a system, followed by attribute studies pivotal for co-living spaces. A potential of product-service systems was explored to facilitate collaboration between students and housing companies. Interviews with students and contextual studies further enriched the understanding of waste management practices. These research methods guided the development of innovative waste management solutions tailored to theunique dynamics of co-living spaces. Stakeholders in this endeavor include students, housing companies, municipalities, and waste management organizations. Instilling correct waste sorting habits, saving costs through reduced fines, more efficient waste processing, and streamlining operations. Our design specifications prioritize user-friendliness, adhering to Nordic sign norms, and a positive user experience. The bins feature designated openings, color coding, visual labels, transparency, and sealable dispensing. Collaborative value is enhanced through interactive elements and aesthetic graphics. We introduce a novel solution: specialized sorting bins with integrated behavioral nudges. Our primary goal is to foster a sense of collective responsibility among residents and promote sustainable waste practices. The final design utilizes recyclable materials. Sustainability is further promoted by encouraging bag reuse. The practical application of sustainability is achieved through nudges and educational graphics on the bins, while social cohesion is fostered through interactive placards. In conclusion, our innovative bin solution offers an effective approach to sustainable waste management in co-living and future work may involve adapting the solution to diverse needs and evolving waste management challenges in shared living environments. / Avfallshantering inom kollektiva (co-living) studentmiljöer saknar effektivisering och understryker vikten av korrekt avfallssortering. För att underlätta samarbetet mellan studenter och bostadsföretag undersöktes potentialen av ett produkt-tjänstesystem för utvecklingen av innovativa avfallshanteringslösningar; detta specifikt för den unika dynamiken i kollektiva utrymmen. Denna potential inkluderar intressenter som studenter, bostadsföretag, kommuner och avfallshanteringsorganisationer som kan leda till förbättringar i korrekta avfallssorteringsvanor, och dessutom spara kostnader genom minskade böter, effektivare avfallshantering och effektivisering av verksamheter. Metoderna som utfördes inkluderade en forskning med hjälp av litteratur, intervjuer och kontextuella studier med studenterna i centrum för att förstå de befintliga avfallshanteringslösningarna, de underliggande systemen, en ökad förståelsen av avfallshanteringsmetoder och relevanta egenskaper. Resultatet blev introduktionen av en lösning i form av specialiserade sorteringskärl som utnyttjar sig av puffning (nudging) för att utöka en känsla av kollektivt ansvar bland invånarna samt utförandet av hållbara avfallsmetoder. Vår designspecifikation prioriterar användarvänlighet, en bättre användarupplevelse och efterliknar de nordiska skyltnormerna. Detta uppnås med variation i former efter typer av förpackning, färgkoder, visuella beteckningar, transparens och förslutningsbar dispensering. För att förstärka samarbetsvärdet användes interaktiva element och estetisk grafik. Kärlen är konstruerade av återvinningsbara material och uppmuntrar därefter återanvändning av säckar tillsammans med kärlen. Den praktiska tillämpningen av hållbarhet uppnås genom puffar och grafiska illustrationer på kärlen, medan social sammanhållning främjas genom interaktiva skyltar. Sammanfattningsvis erbjuder vår innovation en lösning för källsortering på ett effektivt tillvägagångssätt för hållbar avfallshantering i kollektiva utrymmen med ett framtida arbete som kan innebära att anpassa lösningen till olika behov och utvecklande av avfallshanteringsutmaningar i delade livsmiljöer.
