Nowadays, corporations have to consistently advance the value of human assets in their own organizations for maintaining their competitiveness. To achieve this goal, the Human Resource (HR) Dept. plays a decisive role in the aspects of selection, training, employment, and retaining of human resource in the organization. How to improve the efficiency of the HR Dept. and enhance its status in the organizations has become the top agenda to enterprises. The development of Information Technology (IT) transforms the role of the HR Dept. in the organization. It enables HR to be a real strategic partner of corporations through the process of Organization Development. A Human Resource Information System (HRIS) based on the network technology will change the working environment of HR and further lead the transformation of the functions and roles of the HR Dept. Through conducting interviews with 9 companies, this research tries to answer the question, that is, what is the impact to the effectiveness of Human Resource Management when a HRIS is leaded in. It used literature research to analyze the characteristics of Human Resource Management (HRM) and HRIS and sorted out the possible impacts. It also used case study to sharpen the insight by sampling 9 companies which had used HRIS, including foreign and local ones. By doing the work, it drew a conclusion of the impact brought by HRIS and provided a direction of HRIS vendors. The study found that the factors of successfully leading HRIS into a company include the integration with original data, combination with the existing Enterprise Resource Planning System (ERPS), the compatibility of the existing HRIS, HR people¡¦s inability of maintaining HRIS, the suitability of HRIS for company¡¦s specific needs, and the support from high-level management. Leading in a HRIS could benefit the company from decreasing the inconvenience of human operations and increasing the quality of HR¡¦s services. The impacts on the effectiveness of HRM can be seen as the indexes which have positive reaction to HRIS: 1. Reward Management: HRIS provides fast calculation of payment and less human operations. Its tracing function in Payment Module and integration with ERPS help data exchange between HRIS and ERPS. 2. Training Development: HRIS keeps thorough training records of employees. It also can display the average training hours per person, training cost, training results, and etc. 3. Appraisal Management: The whole appraisal process can be done through HRIS, even crossing areas. 4. HR Strategy and Planning: Since HRIS is able to provide more precise data analysis, the quality of decision making of high-level management is enhanced with a great progress. 5. Team Management: Through humanity design of HRIS, more participation from employees is involved. Management spreading in different places still can use HRIS as a platform to exchange HR related information.

The thesis characterizes controlling as a tool for measuring processes effectiveness. It explains main drivers and key assumptions of the controlling existence. It is focused on controlling possibilities to be applicable in human resource management. Moreover, it names particular human resource practices and describes methods of the human resource controlling. The objective is to find the appropriate methods of evaluating human resource management effectiveness. Key Plastics Janovice is chosen as a company that already deals with the HR controlling at some level. In the thesis, there is looking for possibilities to apply the HR controlling and to keep current processes at the same time. The model of HR Balanced Score Card is proposed as a general tool for evaluating the effectiveness of employed human resources by the company.

Rapporten baseras på en litteratur- och intervjustudie kring underhållsstrategier och komponentutbyten i kärnkraftverk, med fokus på komponenter som tenderar till att påverkas av åldring i en högre grad. Exemplifiering sker genom en kompletterande fallstudie kring kabel- och rörgenomföringar av typen Brattbergare som har packbitar bestående av ett polymert material. Erhållet resultat av litteratur- och intervjustudien belyser vilka säkerhetsföreskrifter som råder för all kärnteknisk verksamhet i Sverige. Utöver det erhålls information om hur åldring påverkar ett materials egenskaper över tid och att detta ligger till grund för fastställandet av ett system eller en komponents kvalificerade livslängd. I takt med att majoriteten av världens kärnkraftverk närmar sig sin ursprungligt tilltänkta livslängd och planeras underhållas för fortsatt långtidsdrift finns det ett ökat intresse för effektiva underhållsstrategier. Åldershanteringen har en avgörande roll för anläggningens lönsamhet och driftsäkerhet. Fallstudien föreslår två olika underhållsstrategier som stöds av resultatet av litteratur- och intervjustudien. Deras ekologiska påverkan och ekonomiska omfattning beaktas för att utse den metod som har störst potential att öka resurseffektiviteten och minska kostnaderna för underhållsåtgärder. Vald metod går ut på att praktiska tillståndsmätningar tillämpas för att undersöka hårdheten av packbitar till Brattbergare. Hårdhetsmätningarna syftar till att ge indikationer på i vilken grad packbitarna harpåverkats av degraderande åldringsmekanismer under olika förutsättningar. Resultatet av fallstudien överensstämmer med de resultat som noterades i litteratur- och intervjustudien. Packbitarna hårdnar när de åldras. Två miljöbetingelser som tenderar till att påskynda åldringsprocessen är förhöjda temperaturer och stråldoser. Vald metod för fallstudien är praktiskt realiserbar trots vissa begränsningar i befintliga kärnkraftsanläggningar vid Forsmark. Presenterad strategi bör kunna bistå med en ekologisk och ekonomisk optimering av underhållsarbetet för kabel- och rörgenomföringar. / This report is based on a literature study and interviews regarding maintenance strategies and component replacements in nuclear power plants. Focuses of the study are on components which tend to more commonly be affected by degrading aging mechanisms. Exemplification is done with a complementary case study about cable- and pipe transits with packing pieces made of polymeric materials. A frequently used application for cable- and pipe transits in Swedish NPPs is manufactured by MCT Brattberg AB.  Result obtained from interviews with relevant personnel’s and the literature study providing knowledge about prevailing safety regulations at Swedish nuclear facilities. Moreover, information is gained about how aging affects the features of materials over time and that it is the basis for determining the qualified lifetime of systems and components. Further on this could be of specific interest considering that the majority of the worlds NPPs are close to its intended lifetime and soon entering a phase of LTO. A proper aging management is an important factor when it comes to a safe and reliable operation of an NPP.  The case study compares two different maintenance strategies which are supported by the obtained result from interviews and the literature study. Considering ecological and economic impacts of the strategies, the one with the greatest potential to reduce negative influences are exemplified. Chosen method included practical hardness measurement with a portable durometer at packing pieces for cable- and pipe transits. Measured hardness of the packing pieces indicates at what degree which they have been affected by degrading aging mechanisms given different circumstances.   The obtained result from the two different parts of the report is corresponding to each other. Packing pieces consisting polymers hardens as they age. Elevated temperatures and higher dose rates accelerates the aging process. Represented method of the case study is practically viable at existing NPPs at Forsmark. Presented strategy should be able to assist with an ecological and economic optimization maintenance work for cable- and pipe transits.
