The core process is responsible for internal business development and is the process that runs through the organization and the results which creates a value for the customer. Some research suggests that identification of the client's conscious or unconscious needs clarifying the so-called core process in the organization and operations can thus be more effective. The study aims to identify and analyze the experience of the core process within child health care. The method has been interviews with nine managers and 10 clinic nurses in a county. The results show a lack of knowledge regarding core process and process work. However, the respondents have a sense of what the core process is, although the experience of the core process differs between managers and child health nurses in the study. The discussion describes the obstacles and supporting factors for a common core process.   Keywords: core process, child health care, core process management, process in health care, process management / Kärnprocessen står för verksamhetens inre utveckling och är den process som löper tvärs igenom organisationen och vars resultat skapar ett värde för kunden. Det finns forskning som tyder på att identifikation av kundens medvetna eller omedvetna behov tydliggör den så kallade kärnprocessen i organisationen. Genom processledning får medarbetarna en helhetssyn och kunskap om både interna och externa kunders behov. Det har en positiv inverkan på medarbetarnas arbetstrivsel och verksamhetens utveckling. Syftet med studien är att identifiera och analysera upplevelsen av kärnprocessen inom barnhälsovården. Metoden har varit kvalitativa intervjuer med nio verksamhetschefer och 10 BVC-sköterskor i ett av landets län. Resultatet visar på en kunskapsbrist beträffande kärnprocess och processarbete. Däremot har respondenterna en upplevelse av vad kärnprocessen är, även om upplevelsen av kärnprocessen skiljer sig mellan verksamhetscheferna och BVC-sköterskorna i studien. I diskussionen beskrivs hindrande och stödjande faktorer för en gemensam kärnprocess.

Bakgrund: Outsourcing är inget nytt fenomen då transaktionskostnadsteorin formades 1937 som beskrev att företag bör vända sig till marknaden i de fall detta gynnade företaget ekonomiskt. Sedan dess har teorier kring outsourcing förändrats och i dag handlar outsourcing om att kunna fokusera på företagets kärnkompetens och vilka möjligheter och risker outsourcing medför. Läkemedelsbranschen har på senare år börjat outsourca forskning och produktutveckling, vilka ses som kärnprocesser. Det råder därför delade meningar om branschen faktiskt har en kärnprocess. Syfte: Syftet med denna uppsats är att förstå hur och varför läkemedelstillverkningsbranschen outsourcar, om de outsourcade processerna har koppling till företags kärnprocesser och hur outsourcing faktiskt påverkar företaget, både monetärt och icke-monetärt. Metod: Det empiriska materialet insamlades med både kvantitativ och kvalitativ metod. En enkätundersökning genomfördes för att få en generell bild av hur läkemedelstillverkningsbranschen outsourcar för att sedan genomföra tre intervjuer för att få djupare kunskap om varför företag gjort de angivna val kring outsourcing. De intervjuade företagen valdes ut genom ett typiskt urval där företag valdes som svarat utifrån vissa bestämda kriterier. Slutsats: Uppsatsen har belyst att den vanligaste processen att outsourca är tillverkning, men att även forskning och produktutveckling outsourcas till viss del. Detta berodde på att företag upplevde resurs- och kunskapsbrist inom de outsourcade processerna. Studien fann även att sambandet mellan anledningen till och utfallet av outsourcing var svagt. Däremot hamnade den ökade lönsamheten sist inom båda kategorierna. Det påvisades också att det är svårt att definiera en kärnprocess till branschen med anledning av den diversifiering som i dag karaktäriserar branschen. Däremot framkom produktutveckling som den vanligaste kärnprocessen inom företag, där det visade sig att företag inte tenderar att outsourca sin kärnprocess. / Background: Outsourcing is not a new phenomenon. Transaction cost theory was formed in 1937, which described that companies should transfer activities externally when this benefited companies financially. Since then, theories of outsourcing have changed and today, it has been switched to outsourcing of core competencies and a discussion of both opportunities and risks. In recent years the pharmaceutical industry has started to outsource their research and product development, which is considered a core process. Due to this there is a debate whether or not the industry has a core process. Purpose: The purposes of this thesis are to understand how and why the pharmaceutical manufacturing industry is outsourcing, how the outsourced processes relate to their core processes and how outsourcing affects the companies, both monetary and non-monetary. Method: The empirical evidence was gathered with both quantitative and qualitative methods. Firstly, a survey was conducted to get a general picture of how the pharmaceutical manufacturing industry outsources which was then followed by three interviews to gain an in-depth knowledge of why companies have made specified decisions regarding outsourcing. The companies were selected according to a number of specific criteria. Conclusion: The thesis has highlighted that manufacturing is the most common process of outsourcing, but also that research and product development is outsourced to some extent. This was due to the fact that companies experienced resource and knowledge shortage in the outsourced processes. The study also found that the relation between the reason and the outcome of outsourcing was weak. However, the increased profitability ended last in both categories. It was also found that it is difficult to define a core process within the industry due to the diversification that today characterizes the industry. On the other hand, product development appear to be the most common core process within companies, where it also shows that companies tend not to outsource their core process.

Owing to its ability to improve both spectral and energy efficiency of wireless networks, massive multiple-input multiple-output (mMIMO) has become one of the key enablers of the fifth-generation (5G) and beyond communication systems. For successful integration of this promising physical layer technique in the upcoming cellular standards, it is essential to have a comprehensive understanding of its network-level performance. Over the last decade, stochastic geometry has been instrumental in obtaining useful system design insights of wireless networks through accurate and tractable theoretical analysis. Hence, it is only natural to consider modeling and analyzing the mMIMO systems using appropriate statistical constructs from the stochastic geometry literature and gain insights for its future implementation. With this broader objective in mind, we first focus on modeling a cellular mMIMO network that uses fractional pilot reuse to mitigate the sole performance-limiting factor of mMIMO networks, namely, pilot contamination. Leveraging constructs from the stochastic geometry literature, such as Johnson-Mehl cells, we derive analytical expressions for the uplink (UL) signal-to-interference-and-noise ratio (SINR) coverage probability and average spectral efficiency for a random user. From our system analysis, we present a partitioning rule for the number of pilot sequences to be reserved for the cell-center and cell-edge users that improves the average cell-edge user spectral efficiency while achieving similar cell-center user spectral efficiency with respect to unity pilot reuse. In addition, using the analytical approach developed for the cell-center user performance evaluation, we study the performance of a small cell system where user and base station (BS) locations are coupled. The impact of distance-dependent UL power control on the performance of an mMIMO network with unity pilot reuse is analyzed and subsequent system design guidelines are also presented. Next, we focus on the performance analysis of the cell-free mMIMO network, which is a distributed implementation of the mMIMO system that leads to the second and third contributions of this dissertation. Similar to the cellular counterpart, the cell-free systems also suffer from pilot contamination due to the reuse of pilot sequences throughout the network. Inspired by a hardcore point process known as the random sequential adsorption (RSA) process, we develop a new distributed pilot assignment algorithm that mitigates the effect of pilot contamination by ensuring a minimum distance among the co-pilot users. This pilot assignment scheme leads to the construction of a new point process, namely the multilayer RSA process. We study the statistical properties of this point process both in one and two-dimensional spaces by deriving approximate but accurate expressions for the density and pair correlation functions. Leveraging these new results, for a cell-free network with the proposed RSA-based pilot assignment scheme, we present an analytical approach that determines the minimum number of pilots required to schedule a user with probabilistic guarantees. In addition, to benchmark the performance of the RSA-based scheme, we propose two optimization-based centralized pilot allocation schemes using linear programming principles. Through extensive numerical simulations, we validate the efficacy of the distributed and scalable RSA-based pilot assignment scheme compared to the proposed centralized algorithms. Apart from pilot contamination, another impediment to the performance of a cell-free mMIMO is limited fronthaul capacity between the baseband unit and the access points (APs). In our fourth contribution, using appropriate stochastic geometry-based tools, we model and analyze the downlink of such a network for two different implementation scenarios. In the first scenario, we consider a finite network where each AP serves all the users in the network. In the second scenario, we consider an infinite network where each user is served by a few nearby APs in order to limit the load on fronthaul links. From our analyses, we observe that for the finite network, the achievable average system sum-rate is a strictly quasi-concave function of the number of users in the network, which serves as a key guideline for scheduler design for such systems. Further, for the user-centric architecture, we observe that there exists an optimal number of serving APs that maximizes the average user rate. The fifth and final contribution of this dissertation focuses on the potential improvement that is possible by the use of mMIMO in citizen broadband radio service (CBRS) spectrum sharing systems. As a first concrete step, we present comprehensive modeling and analysis of this system with omni-directional transmissions. Our model takes into account the key guidelines by the Federal Communications Commission for co-existence between licensed and unlicensed networks in the 3.5 GHz CBRS frequency band. Leveraging the properties of the Poisson hole process and Matern hardcore point process of type II, a.k.a. ghost RSA process, we analytically characterize the impact of different system parameters on various performance metrics such as medium access probability, coverage probability, and area spectral efficiency. Further, we provide useful system design guidelines for successful co-existence between these networks. Building upon this omni-directional model, we also characterize the performance benefits of using mMIMO in such a spectrum sharing network. / Doctor of Philosophy / The emergence of cloud-based video and audio streaming services, online gaming platforms, instantaneous sharing of multimedia contents (e.g., photos, videos) through social networking platforms, and virtual collaborative workspace/meetings require the cellular communication networks to provide high data-rate as well as reliable and ubiquitous connectivity. These constantly evolving requirements can be met by designing a wireless network that harmoniously exploits the symbiotic co-existence among different types of cutting-edge wireless technologies. One such technology is massive multiple-input multiple-output (mMIMO), whose core idea is to equip the cellular base stations (BSs) with a large number of antennas that can be leveraged through appropriate signal processing algorithms to simultaneously accommodate multiple users with reduced network interference. For successful deployment of mMIMO in the upcoming cellular standards, i.e., fifth-generation (5G) and beyond systems, it is necessary to characterize its performance in a large-scale wireless network taking into account the inherent spatial randomness in the BS and user locations. To achieve this goal, in this dissertation, we propose different statistical methods for the performance analysis of mMIMO networks using tools from stochastic geometry, which is a field of mathematics related to the study of random patterns of points. One of the major deployment issues of mMIMO systems is pilot contamination, which is a form of coherent network interference that degrades user performance. The main reason behind pilot contamination is the reuse of pilot sequences, which are a finite number of known signal waveforms used for channel estimation between a user and its serving BS. Further, the effect of pilot contamination is more severe for the cell-edge users, which are farther from their own BSs. An efficient scheme to mitigate the effect of pilot contamination is fractional pilot reuse (FPR). However, the efficiency of this scheme depends on the pilot partitioning rule that decides the fraction of total pilot sequences that should be used by the cell-edge users. Using appropriate statistical constructs from the stochastic geometry literature, such as Johnson-Mehl cells, we present a partitioning rule for efficient implementation of the FPR scheme in a cellular mMIMO network. Next, we focus on the performance analysis of the cell-free mMIMO network. In contrast to the cellular network, where each user is served by a single BS, in a cell-free network each user can be served by multiple access points (APs), which have less complex hardware compared to a BS. Owing to this cooperative and distributed implementation, there are no cell-edge users. Similar to the cellular counterpart, the cell-free systems also suffer from pilot contamination due to the reuse of pilot sequences throughout the network. Inspired by a hardcore point process known as the random sequential adsorption (RSA) process, we develop a new distributed pilot assignment algorithm that mitigates the effect of pilot contamination by ensuring a minimum distance among the co-pilot users. Further, we show that the performance of this distributed pilot assignment scheme is appreciable compared to different centralized pilot assignment schemes, which are algorithmically more complex and difficult to implement in a network. Moreover, this pilot assignment scheme leads to the construction of a new point process, namely the multilayer RSA process. We derive the statistical properties of this point process both in one and two-dimensional spaces. Further, in a cell-free mMIMO network, the APs are connected to a centralized baseband unit (BBU) that performs the bulk of the signal processing operations through finite capacity links, such as fiber optic cables. Apart from pilot contamination, another implementational issue associated with the cell-free mMIMO systems is the finite capacity of fronthaul links that results in user performance degradation. Using appropriate stochastic geometry-based tools, we model and analyze this network for two different implementation scenarios. In the first scenario, we consider a finite network where each AP serves all the users in the network. In the second scenario, we consider an infinite network where each user is served by a few nearby APs. As a consequence of this user-centric implementation, for each user, the BBU only needs to communicate with fewer APs thereby reducing information load on fronthaul links. From our analyses, we propose key guidelines for the deployment of both types of scenarios. The type of mMIMO systems that are discussed in this work will be operated in the sub-6 GHz frequency range of the electromagnetic spectrum. Owing to the limited availability of spectrum resources, usually, spectrum sharing is encouraged among different cellular operators in such bands. One such example is the citizen broadband radio service (CBRS) spectrum sharing systems proposed by the Federal Communications Commission (FCC). The final contribution of this dissertation focuses on the potential improvement that is possible by the use of mMIMO in the CBRS systems. As our first step, using tools from stochastic geometry, we model and analyze this system with a single antenna at the BSs. In our model, we take into account the key guidelines by the FCC for co-existence between licensed and unlicensed operators. Leveraging properties of the Poisson hole process and hardcore process, we provide useful theoretical expressions for different performance metrics such as medium access probability, coverage probability, and area spectral efficiency. These results are used to obtain system design guidelines for successful co-existence between these networks. We further highlight the potential improvement in the user performance with multiple antennas at the unlicensed BS.
