This thesis is the final part of bachelors program of Nuclear Engineering at UppsalaUniversity (program code KKI1). The work has been carried out in cooperation withForsmark Kraftgrupp AB. The topic studied deals with possible improvements ofefficiency at the planning department at block 2 in Forsmark i.e. FMP2. FMP2 plans and coordinates over 3,000 operations which is carried out during theannual overhaul of block 2 in Forsmark. Inspections, fuel replacement and repairs areincluded in the annual overhaul. The overhaul shall contribute to secure and reliableoperation of the block. The overhaul shall mitigate the risk of unplanned downtime. Also accidents, financiallosses and damage to reputation among public and the Regulators (i.e. SSM and IAEA)shall be avoided. The time for overhaul depends on actions that must be executedand the complexity of the work. Normally, the overhaul time last for a number ofweeks and in rarely cases it can last for months. One topic in the thesis has been to find and describe a way for the planningdepartment (FMP2) to improve status control in ongoing overhaul activities and toincrease the planning department efficiency i.e. to save time for the planningdepartment. With better status control and faster work in the planning departmentthe total overhaul time can be expected to be shortened. Additionally the thesisdiscusses the importance of reliable and secure nuclear power management with therespect to society. The thesis is partly based on examine of current work practices, a literature studyand interviews with employees. The literature study addresses interaction betweenhumans and technology and how to accomplish good decisions. The interviews havebeen made to gather experiences from earlier used working methods. This report shows that FMP2 's current working model is good, although not perfect.It is probable that efficiency improvements at the individual level can be reached thatincreases employed personnel working capacity. Enhanced efficiency can also bereached by using better computer programs that manages the functions that currentlyrequire several separate IT-systems. A number of recommendations are given in thereport for how operations can be improved. Among other things, a proposal toexplore how extraordinary working efforts shall be rewarded. The nuclear power energy importance for the Swedish electricity power balance hasbeen discussed. The conclusion is that customers, electricity generators and thepublic benefits from reliable and secure nuclear power management.

Att bedöma hur mycket resurser man ska lägga på ett uppdrag är inte alltid lätt. Det finns åtskilliga metoder att på ett kvalificerat sätt ställa upp ett anbud och en prognos på vad uppdraget kommer att kosta, en av dessa metoder är erfarenhetsåterkoppling. Med hjälp av erfarenhetsåterkoppling finns det möjlighet att lokalisera nyckeltal som är utslagsgivande för anbudsprocessen. Dessa nyckeltal är givande att känna till innan anbudet läggs fram för att veta om uppdraget är lönsamt i den nuvarande formen eller behöver justeras. För entreprenörer finns det hjälpmedel som till exempel ÅF:s lilla prisbok, men för konsulter så saknas till viss del hjälpmedel. En del konsulter jobbar med individuell erfarenhetsåterkoppling men det krävs ofta några år i branschen för att skapa sig den erfarenhet som behövs. Dessutom har företagets övriga medarbetare sällan möjlighet att ta del av denna information på ett smidigt sätt. Syftet med examensarbetet var därför att sammanställa en erfarenhetsbank av tidigare färdigställda uppdrag och utveckla nyckeltal som kan användas till framtida anbudsförfrågningar. De frågeställningar som tagits fram för detta examensarbete var: · Vilka nyckeltal är relevanta för kommande anbud? · Finns det korrelation och samband mellan dessa nyckeltal samt hur påverkas nyckeltalen av parametrarna? · Vilken typ av uppdrag ger störst marginal, utifrån projekteringsfas, objekttyp, teknisk komplexitet och huruvida det var en om- eller nybyggnad? Examensarbetet behandlar erfarenhetsåterkoppling från ett konsultperspektiv inom projekteringsskedet i byggprocessen. De resultat som framtagits har gjorts med hjälp av Tyréns interna ekonomisystem och en enkätundersökning där uppdragsansvariga fick svara på frågor om sina uppdrag. Undersökningen resulterade i ett antal samband som visar på hur parametrar som objekttyp, teknisk komplexitet och bruttoarea påverkar uppdragets totala tid, marginal, mm. Dessutom utvecklades ett anbudsvektyg som kan användas som en indikation för kommande anbud. De slutsatser som kunnat göras i examensarbetet är bland annat att parametern tekniska komplexitet har en stor inverkan på tre av fyra nyckeltal marginal, total tid och TPR. För ekonomisk marginal hade varken objekttyper eller projekteringsfas lika stor inverkan på det den slutliga marginalen. Det visade sig även att om- och nybyggnation hade stor inverkan på de fyra nyckeltalen TPR, marginal, total tid och TPm2. / Determining how much time and resources ought to be committed on a certain project is not an easy task. There are several of different methods that can be used achieve a solid approximation for a tender, and one of these is by using experience feedback. It is possible, through the use of experience feedback, to construct key ratios based on previously completed project. These key ratios could then be of significant help in upcoming tender process. For estimating the construction cost, builders can use tools such as ÅF:s lilla prisbok. But these types of tools are not as common practice for the consultants planning the construction. This leads us to the purpose of this thesis, which is to collect and set up a database of previously completed projects and from this database develop key ratios that can be used in upcoming tenders. The questions posed by this report was: · Which key ratios are most relevant for upcoming tenders? · Are there any correlations and connections between these key ratios and how are these key ratios affected by the parameters? · Which type of project generates the greatest financial margin, based on design phase, the type of object that was designed, technical complexity and whether the project is a new construction or a reconstruction. This thesis looks at experience feedback from the perspective of a consultant firm working with the planning of buildings and infrastructure. All the results were collected through the use of Tyréns internal economy system as well as a survey were project leaders had to answer questions about the project that they had been in charge of. This investigation resulted in a number of correlations and connections that showed how certain parameters such as technical complexity affected the project total time, profit and so on. A tender approximation tool was created based on data gathered from previously finished projects. Finally, the conclusions that were drawn in this report was, among other things, that the level of technical complexity has a significant effect on three of the four key ratios analysed in this report. These three key ratios were financial margin, total time and time per design plan. The financial margin was not affected by neither the type of object that were designed nor the phase of the design process. The report also concludes that all four key ratios were considerably affected by whether the project is a new construction or a reconstruction.
