This paper concerns the subject of temporary employments and how the employment status affects the personal life of the employee. The aspects of the personal life which are being investigated is the employees possibilities to plan their long term future as well as their short term future. Furthermore, the employees social relations and spare time are being investigated. The paper is qualitative and is based on semi-structured interviews with four people between the age of 25 and 35 who are experienced with temporary employment. The results of the interviews are analyzed in light of Richard Sennetts theory about ”The corrosion of character”, which shows upon a contradiction between the character-building and today's job market. The conclusions are that the employees possibilities concerning long term planning, as well as short term planning, is aggravated by their temporary employment status. Their spare time seems to become less extensive and the time devoted to the social relationships decreases. However, we can not draw any conclusions on the social relations patterns affected at a deeper level. / Denna uppsats berör ämnet tidsbegränsade anställningar och hur anställningsformen påverkar den anställdes privatliv. De aspekter av privatlivet som undersöks är den anställdes möjligheter till lång- samt kortsiktig planering och sociala relationer samt fritid. Studien är kvalitativ och resultatet bygger på semistrukturerade intervjuer med fyra personer mellan 25 år och 35 år vilka alla har erfarenhet av tidsbegränsade anställningsformer. Resultatet från intervjuerna analyseras i ljuset av Richard Sennetts teori ”När karaktären krackelerar”, som visar på en motsättning mellan mänskligt karaktärsbyggande och dagens arbetsliv. Slutsatserna som dras är att den långsiktiga och kortsiktiga planeringen försvåras av den tidsbegränsade anställningsformen. Fritiden blir mindre omfattande och de sociala relationerna ägnas det mindre tid åt; dock kan vi inte uttala oss om de sociala relationernas mönster påverkats på ett djupare plan.

This diploma thesis deals with a new concept of maintenance and operation of production technologies, where spare parts are manufactured using rapid prototyping methods. The options are compared with currently used methods. Furthermore, methodological recommendations are written on how to proceed with the application. The aim of the work is to evaluate the concept and confirm the theoretical assumptions on a case study.

This thesis deals with the estimate of damage of an automobile caused during a car accident with no injuries involved. A significant part of my work consist of a sociological research, a proceeding during a car crash a fleet analysis and protocols from a programme called Audatex. The outcome is a brochure - "How to manage a car accident - with detailed description how to estimate the damage caused by the crash"

This thesis studies the problem of modeling life-limited spare units in a steady-state scenario. This means that units that have a predefined lifespan are to be modeled in a scenario where all conditions are kept constant and all transients have faded out. OPUS10 is a spare parts optimization software developed by Systecon AB. There is no way to explicitly model the life-limited units in OPUS10, although there are different approximate models that are built on adjustments of the failure rate and repair fraction or the definition of preventive maintenance. The objective of this thesis is to analyze the usage of life-limited items in real life and to investigate what approximated models different OPUS10 users will utilize in their modeling of life-limited units. Furthermore, the objective is to analyze the consequences of the approximated models and to investigate the possibility of an improved model. The results show that the main interest when choosing which approximated model to use is the type of life limit. There are three different types of operating time life limits investigated. Either the unit is discarded immediately after the life limit is reached, or it is instead discarded at the next failure. There is also the possibility of resetting of the life limit timer at each maintenance. In all three cases, it is shown that if choosing the most fitting approximate model, the results are very accurate. If the life limit is instead measured in calendar time, even the best approximation will give an under-estimation of the expected number of backorders. It is also shown that most of the OPUS10 users model life-limited units as preventive maintenance with discard, which is not the best approximation in any of the types of life limits.

The purpose of this degree project is to investigate in what types of situations and to what extent some upper secondary students write in English in their spare time, what reasons they have for doing so and what text types and genres are represented in their writing. Qualitative interviews were carried out with a group of six students in year two in an upper secondary school in the southern part of Sweden, three with MVG as a final grade and three with VG as a final grade in English A.The results show that all of the students write in English each day in instant text messages on MSN messenger. However, they mostly use English in the form of abbreviations, single words, phrases and sentences. Longer pieces of text, like poems and other literary pieces, written in English were created only by the three students with MVG.

Purpose: The purpose of this study was to analyze possible strategies that can be used to improve the efficiency of the spare parts safety stock management in a multinational company which operates in the electronic industry. Research question: “Which safety stock dimensioning strategies are most suitable in an after-sales business environment, characterized by high level customer service and unpredictable demand?” Method: The theoretical framework illuminated the study’s phenomenon which was mainly based on peer-reviewed scientific articles but also academic books. Furthermore, the empirical data collection in this study was conducted through a mixed research approach, where the qualitative data was collected through three semi-structured interviews and several unstructured interviews, while the quantitative data consisted of calculations using numerical variables provided by the case company. Conclusion: The study concluded that the so called estimated safety stock method as well as the probabilistic demand based on history method are the most suitable safety stock dimensioning strategies to utilize in business environments where firms that offer products with unpredictable demand are facing challenges related to finding a balance between providing a high service level and keeping their costs as low as possible. / Syfte: Syftet med denna studie var att analysera möjliga strategier som kan användas för att förbättra säkerhetslagerhanteringen av reservdelar hos ett globalt företag inom elektronikindustrin. Frågeställning: “Vilka dimensioneringsstrategier för säkerhetslager är mest lämpliga i en eftermarknadsverksamhet, kännetecknad av hög servicenivå och oförutsägbar efterfrågan?” Metod: Det teoretiska ramverket belyste studiens fenomen som var baserad på främst expertgranskade vetenskapliga artiklar men även böcker. Vidare genomfördes den empiriska datainsamlingen i denna studie genom en mixad forskningsmetod, där den kvalitativa datan var i form av fyra semistrukturerade intervjuer samt flera ostrukturerade intervjuer, medan den kvantitativa datan bestod av beräkningar med hjälp av numeriska variabler tillhandahållna av fallföretaget. Slutsats: Studiens slutsatser visade att den så kallade manuellt bedömt säkerhetslager metoden samt probabilistisk efterfrågan baserad på historisk data metoden är de mest lämpliga dimensioneringsstrategier för säkerhetslager att använda i affärsmiljöer där företag som erbjuder produkter med oförutsägbar efterfrågan står inför utmaningar relaterade till att hitta en balans mellan att tillhandahålla en hög servicenivå och att ha så låga kostnader som möjligt.

The rapid digital development has transformed our lives, and today we can work in new ways compared to before. With an increased demand for flexible work arrangements, where the home serves as a workplace, it is crucial for companies to understand how this affects the well-being of employees. Therefore, the purpose of this study is to examine how the possibility of work flexibility promotes individuals well-being. Previous research points out several factors that can influence well-being during remote work, including the work environment, the balance between work and private life, and interaction. The theoretical framework of the study is primarily based on Karasek and Theorell's demand-control-support model (1990), but in specific sections, support will also be drawn from studies by Kangas et al. (2023) and Espersson et al. (2023) using the concepts of Family-supportive supervisor behaviors and urholkade sociala relationer. The study is based on qualitative interviews conducted with employees in various units at Västerås municipality who work part-time at the physical workplace and part-time remotely. The results show that remote work is significant, especially for employees work-life balance, which positively impacts their well-being. What is really important for well-being is the ability to manage and plan worktasks on your own, no matter where you're working. / Den snabba digitala utvecklingen har förändrat våra liv och idag kan vi arbeta på nya sätt jämfört med tidigare. Med en ökad efterfrågan på flexibelt arbete med hemmet som arbetsplats, är det viktigt att företag är insatta i hur detta påverkar medarbetarnas välbefinnande. Syftet med studien är därför att undersöka hur möjligheten till arbetsflexibilitet främjar individers välbefinnande. Tidigare forskning visar på flera faktorer som kan påverka välbefinnandet under distansarbete, såsom arbetsmiljön, balansen mellan arbete och privatliv samt interaktionen. Studiens teoretiska ramverk utgår huvudsakligen från Karasek och Theorells krav-kontroll-stödmodell (1990), men i särskilda avsnitt kommer även stöd tas från studier av Kangas m.fl. (2023) och Espersson m.fl. (2023) med begreppen Family-supportive supervisor behaviors och Urholkade sociala relationer. Studien baseras på kvalitativa intervjuer som genomförts med medarbetare inom olika enheter på Västerås kommun som arbetar halvtid på den fysiska arbetsplatsen och halvtid på distans. Resultatet visar att distansarbete är betydelsefullt, speciellt för medarbetarnas livspussel, vilket har en positiv inverkar på deras välbefinnande. Det som framkommer som avgörande för välbefinnandet är förmågan att självständigt styra och planera arbetsuppgifterna, oavsett platsen för arbetet.

Aim: The aim of this study is to investigate the need for a central warehouse for spare parts distribution in the after-sales market for manufacturing companies. Research question: What are the potential benefits and challenges of a central warehouse for spare parts distribution in the after-sales market for manufacturing companies? Method: This study has been inspired by the deductive approach with a qualitative research design, and with a case study. A literature survey has been carried out, where previous scientific research has been analysed. Empirical data was collected from the case company with interviews in both structured and semi-structured form. Based on an analysis of literature and theory, a conclusion has been drawn up. Conclusion: Both benefits and challenges have been identified, but the study shows that more benefits than challenges have been confirmed. Thus, it can be concluded that a central warehouse will show more value in terms of benefits for companies, but not without facing some challenges on the way.

Additive manufacturing is described in literature as a disruptive technology for spare parts supply chains and shows the potential to impact business models for spare parts production through various advantages over conventional manufacturing. Understanding changes in business models is important for companies to adopt any technology and explore business opportunities around it. This research aims to fill the gap in literature on how business models change when additive manufacturing is used for spare parts production in the automotive industry. To investigate those changes a qualitative research design with semi-guided interviews with experts in automotive companies was chosen. The findings showed that the adoption of additive manufacturing in the automotive industry is generally slow and only a few spare parts are specifically developed for additive manufacturing. Especially for niche low-volume and high-value applications AM is already used. At the same time identifying new business cases is needed for broader adoption. Contrasting opinions in literature that additive manufacturing is a disruptive technology, the adopters referred to it rather as a tool. Moreover, the findings showed that the potential of additive manufacturing described in literature is still there but cannot be utilized yet due to various identified barriers at the current stage. The main identified barriers are lack of knowledge, suitable manufacturing data, and resources to explore additive manufacturing.
