På kraftvärmeverket Allöverket I Kristianstad produceras processvattnet i en anläggning som heter totalavsaltningen. I denna anläggning som består ut av två identiska linjer låter man det inkommande vattnet passera genom jonbytare för att byta ut de oönskade jonerna i vattnet emot mer önskade. Anledningen till att man gör detta är att de oönskade jonerna i vattnet ger beläggningar på turbinen. När jonbytarna blivit mättade så måste de återställas till sin ursprungliga form. Detta sker genom att det startas ett regenereringsprogram, som består av ett antal steg så som backspolning, kemikalieintag och fyra olika spolningar. Det finns gränsvärden för vilken ledningsförmåga samt vilken halt av kisel vattnet skall ha för att få levereras men det finns endast mätning av ledningsförmåga kopplat till styrsystemet vilket gör att man får styra anläggningen efter olika tider. Till styrsystemet är det kopplat ett antal centrifugalpumpar och magnetventiler samt mätutrustning för mätning av ledningsförmåga. I totalavsaltningen sitter det ett Siemens S5 styrsystem som styr anläggningen efter vattenmängd, ledningsförmåga och olika tider för sekvenserna. Alla de styrande funktionerna sitter på ett styrskåp ute i fabriken. Siemens systemet är gammalt och omodernt och skall därför bytas ut emot ett ABB 800xA system. Detta system används redan på operatörsstationerna i manöverrummet för att styra andra delar av fabriken. Med denna studie så har jag tagit fram en ny funktionsbeskrivning av totalavsaltningen. Funktionsbeskrivningen består ut av funktionsdiagram som beskriver hur programmet styr anläggningen idag. Till funktionsbeskrivningen har jag också gjort en ny teknisk beskrivning samt reviderat det processchema som finns över anläggningen för att all dokumentation skall hänga samman. / The heat and power station Allöverket in Kristianstad produced the process water in a plant called the total desalination. In this plant which consists out of two identical lines, they let the incoming water passing through ion exchangers to replace the undesired ions in the water to more desired ions. The reason for doing this is that the undesired ions in the water give coatings on the turbine. When the ion exchangers have been saturated, they must be restored to the original condition. This is done by starting a regeneration program, which consists of a number of steps such as back flushing, intake of chemicals and four different flushes. There are limits on the conductivity and the content of silicon in the water that will be delivered. But there is only measurement of the conductivity connected to the control system, and because of this they control the plant with different timers. To the control system there is connected a number of centrifugal pumps, solenoid valves and instrumentation for measurement of conductivity. In the total desalination sits a Siemens S5 control system that controls the plant after amount of water, conductivity and different times of the sequences. The control functions are now located on a control cabinet out of the factory. The Siemens S5 control system is old and outdated and will be changed to an ABB 800xA control system. This control system they already use to control other parts of the factory from the control room. With this study I have developed a new functional description of the plant and it consists of function diagrams which describes how the software controls the plant today. To the function description, I have also made a new technical description and revised the process scheme so that all documentation of the plant says the same thing.

TESIS PARA OPTAR AL GRADO DE MAGÍSTER EN CONTROL DE GESTIÓN / presente trabajo se enmarca en el diseño de un Sistema de Control de Gestión para una Unidad Estratégica de Negocio (en adelante UEN) perteneciente a la empresa Siemens S.A., denominada “Centro de Operaciones de Ingeniería”. Esta UEN desarrolla proyectos para las áreas de automatización y control de diversos sectores industriales del país. El desarrollo de proyectos es una actividad compleja, no exenta de riesgos y que reúne a varios grupos de interés (clientes, proveedores, accionistas, comunidades, etc.), que perciben y evalúan el éxito o fracaso de la actividad de diversas maneras. Los proyectos también se caracterizan por requerir un alto nivel de control de las operaciones, dada la necesidad de coordinar la correcta asignación de recursos y tareas durante toda la fase de ejecución. Uno de los principales problemas que enfrenta la gerencia de esta UEN, es hacer que los resultados de cada proyecto sean acordes a la estrategia del negocio, logrando así que los resultados sean favorables para todos los grupos involucrados. Lamentablemente, la baja integración de las operaciones con la estrategia produce que la gerencia se involucre demasiado en temas operativos, debiendo estar ésta enfocada a alcanzar resultados financieros de corto plazo. Esto deja muy poco tiempo al análisis de los temas estratégicos y coloca en riesgo la sustentabilidad a largo plazo del negocio. Esta situación se presenta como una gran oportunidad para poner en práctica los conocimientos y habilidades adquiridos con el fin de diseñar un Sistema de Control de Gestión que liberará a la gerencia de tareas operativas, entregándoles herramientas para dirigir sus esfuerzos al diseño, implementación y corrección de la estrategia. El trabajo se desarrolla considerando un análisis y propuestas para la situación de la UEN en tres etapas: Formulación Estratégica, Desarrollo de la Estrategia y Alineamiento Estratégico. Como último punto se incluyen las experiencias y conclusiones más importantes generadas al finalizar el presente trabajo. / 2017-07

BillerudKorsnäs i Gävle är ett pappersbruk som tillverkar två typer av kartong: vätskekartong och White Top Liner. Varje höst genomförs ett veckolångt stopp där all produktion stoppas för att möjliggöra för underhåll, reparationer och nyinstallationer. Ett av projekten i årets höststopp innefattar en uppgradering av styrsystemet som tillhör hylskapen på pappersmaskin 4. För att installationen och driftsättningen av systemet ska ske effektivt krävs det att så mycket som möjligt är förberett. I denna rapport redovisas arbetet som har genomförts för att programmera det nya styrsystemet och en ny operatörspanel samt implementera en ny servodrift. Målsättningen var att färdigställa komponenterna så långt som möjligt och samtidigt på ett så bra sätt som möjligt så att uppgraderingen resulterar i en klar förbättring av hylskapens styrning. Operatörspanelen ansågs ha stor betydelse för förbättringen och därför lades mycket fokus på att skapa ett användarvänligt användargränssnitt. Metoden som användes vid utvecklingen hade dock kunnat förbättras för att utnyttja tiden mer effektivt. För att få en uppfattning om hylskapens funktion gjordes en mindre fallstudie. Det utfördes även intervjuer med alla skiftlag för att uppmärksamma eventuella önskemål gällande förbättrande funktioner. Under intervjuerna diskuterades även användargränssnittet vilket resulterade i att det fick en design som alla operatörer var nöjda med. Styrsystemet programmerades utifrån det gamla programmet men modifierades med de nya funktionerna, som till exempel servodrift och kalibreringsalternativ. Programmeringen testades kontinuerligt under hela arbetet i en testrigg bestående av en servodrift, ett styrsystem och en operatörspanel. Arbetet resulterade i att servot kunde styras via operatörspanelen på det sätt som efterfrågades. Uppgraderingen leder förhoppningsvis till att hanteringen av operatörspanelen förenklas. Flexibiliteten hos operatörspanelen gav möjlighet till att utöka hylskapens funktioner på ett smidigt sätt som inte varit möjligt tidigare, vilket förenklar ytterligare utveckling. / BillerudKorsnäs in Gävle is a paper mill that manufactures liquid-packaging board as well as white top liner (WTL). A week-long manufacturing stop is carried out each autumn so that repairs, maintenances, and installations can be accomplished. One of the projects that are going to be commissioned this autumn is about upgrading the control system of the core cutter associated with board machine 4. It is necessary that every component is prepared optimally so that the installation and commissioning runs effectively. This report describes the preparatory work that has been done to the control system, an operator panel, and a servo drive. The objective was to prepare every component in the best possible way so that the results of the upgrade would be significant improvements of the core cutter. The operator panel was considered important in the development and a lot of work was therefore put into creating a user-friendly interface. However, the method that was used to develop the interface could have been improved to make it more time efficient. A small case study was conducted to grasp an understanding of the core cutter functions. Interviews were done with the operators to understand better their ideas about enhancing certain features. The user interface and its design were also discussed during the interviews, resulting in a layout that the operators were pleased with. The control system program was based on the old control program in which new functions were added into, e.g., the servo drive and a calibration function. Various devices and their programs were also tested throughout the whole project using a test rig. The test rig contained a control system, an operator panel, and a servo drive with a motor. The result was successful. It was possible to control the servo drive with the operator panel. Hopefully the upgrade leads to a major improvement of the core cutter control. The flexibility of the new operator panel created new possibilities to streamline the functions better than before and thus simplifies further development.

This case study was written within the broader concept of Organisational Culture and how it is integrated into an organisation to encourage responsible leadership. The core focus and emphasis of this approach is to establish the implications for businesses operating in the most challenging of commercial environments, while adhering to their corporate ethos and organisational values. These may be summarised with the phrase: Only a clean business is a sustainable business. This dissertation is intended to act as a case study and resource aide for the teaching of leadership, organisational behaviour, human resources and business sustainability. The study is about the Afghanistan chapter of the global giant Siemens, which has been working in many areas of specialisation conducting business in the country for more than 75 years. It has been selected for this case study because of its long-term impressive record, during which time it has developed and sustained a reputation as an organisation with a much-admired organisational culture, and one to which employees feel very closely attached and connected. This case study evolved from a set of unique as well as difficult circumstances. In Afghanistan, where infrastructure is weak, businesses and other structured organisations are in their initial and immature stages of development, and employee attachment to their workplaces is relatively weak. In the case of Siemens however, it has been much the opposite. It became apparent over a protracted period of time that the relationship of employees to the company was clearly of a positive and committed nature, unlike the general perception stemming from other multinational organisations operating within the country. Many business organisations in Afghanistan tend to emphasise to a lesser degree some modern-day practices of employer-employee relationships, which negatively affect motivation and commitment. The study grew out of the observations that employees of Siemens on the other hand, seemed to exhibit attitudes and commitments contrary to the general trend in the wider business sector. This project began with the intention to identify those factors contributing to employee loyalty and strong attachments to an organisation. Subsequently, the same findings were used to identify the traits and particular features working within the organisational environment.
