In recent years, Hallsta Paper Mill has experienced significant changes in the demand for paper. The ordershave become smaller and more customer-specific, while the graphical paper industry has steadily declined.As a result of these changes, the employees at Hallsta Paper Mill feel that the finished goods warehouse isno longer optimally designed, and they have identified that waste occurs in the warehouse. Therefore, thepurpose of the study was to provide suggestions on how the activities in the warehouse could become moretime-efficient and investigate how the finished goods warehouse could be designed to suit today’s demandbetter. To facilitate the answering of the purpose, three research questions were formulated: What areas ofimprovement exist in the finished goods warehouse regarding its activities and layout? What effects can beobtained by addressing the identified areas of improvement? and What solutions are recommended for thefinished goods warehouse at Hallsta Paper Mill? The study’s first research question was answered by conducting interviews, a spaghetti diagram, and ananalysis of produced paper rolls. The interviews were conducted with employees who either workoperationally or administratively in the warehouse to get a comprehensive picture of how the work isperformed and where waste occurs within the activities. The spaghetti diagram identified the movementpattern for the trucks in the warehouse and provided indications if unnecessary long transports occurred ornot. The analysis of produced paper rolls examined how well the storage compartments in the finishedgoods warehouse were dimensioned based on today’s demand. Based on the collected data, nine areas ofimprovement were identified, seven areas linked to the activities in the warehouse and two areas linked tothe layout of the warehouse. After the areas of improvement were identified, the study’s second research question was answered bydeveloping solutions within each area of improvement. To develop the solutions linked to the activities inthe warehouse, root cause analyses were performed, where each area was examined to find the root causeof the problem. For the solutions linked to the design, inspiration was instead taken from the warehouselayout and article placement literature. A total of 23 solutions were developed, 19 linked to the activitiesand four linked to the layout. For each solution, it was then analysed what effects an implementation of thesolution would provide, focusing on possible time savings. The effects were analysed with help from theliterature and the authors’ knowledge of logistics. After the effects had been analysed, each solution was assessed based on the effects identified in theprevious research question. The solutions were placed in effort-impact diagrams based on how much effortis required to implement the solution and how much impact is expected from the solution. When assessingthe impact, extra consideration was given to possible time savings, as it was the highest priority accordingto the directives from Hallsta Paper Mill. The assessment then resulted in a recommendation on how thesolutions should be approached. The less effort required and the more impact a solution would bring, thehigher priority was given to the solution. To summarise, two solutions were recommended to beimplemented immediately, nine solutions should be implemented in a second step, seven solutions shouldbe considered and investigated further, and two solutions should be rejected. The solutions aimed to makethe warehouse activities more time-efficient and suggest how the warehouse could be designed to suittoday’s demand better.

Byggsektorn tenderar idag att välja material med låg miljöpåverkan och bygga energi- och tidseffektiva konstruktioner. Att öka användningen av träprodukter är en del av lösningen. Korslimmat trä (KL-trä) är ett byggmaterial som har blivit mer och mer populärt att använda i byggbranschen. I Sverige har KL-trä använts sedan slutet på 90- talet och användandet ökar för varje år som går. Materialet är relativt nytt och vid monteringen av KL-trä finns det utrymme för förbättringar. Syftet med arbetet är att undersöka och analysera hur dagens infästning av KL-element utförs och hur dessa kan effektiviseras. Målet är att undersöka om det går att korta ner monteringstiden av KL- trästommar. Detta görs genom beräkningar, fältstudie och experiment. I arbetet undersöks möjligheten att reducera skruvning för det vanligast använda vägg till golv anslutningarna och om det finns tid att spara i montaget med hjälp av förborrning. Resultatet av rapporten visar att det finns en potentiell tid motsvarande ca 40 % tidsvinst att spara med förborrade bjälklag från fabrik och andra kvalitétsfördelar som förborrning kan medföra, medan reducering av skruv är möjligt men inte optimerad för dagens mest tillämpade infästningslösningar. / The construction sector today tends to choose material with a low environmental impact and build energy- and time-efficient structures. Increasing the use of wood products is part of the solution. Cross laminated timber (CLT) is a building material that has become more and more popular to use in the construction industry. In Sweden, CLT has been used since the late 90 and its use is increasing every year. The material is relatively new and especially for mounting CLT element, there are still potentials for improvement. The purpose of the work is to investigate and analyze how todays attachment of CLT elements is carried out and how these can be made more efficient. The aim is to investigate whether it is possible to shorten the assembly time of CLT elements. The study was carried out through calculations, study visit and experiments. The work investigates the possibility of reducing screwing for the most commonly used wall to floor joints and showed there is a potential time efficiency of about 40% to be gained with pre-drilled floor element from the factory and other quality benefits that pre-drilling can bring, while the study also showed reducing fasteners under construction phase is possible but not an optimal solution.

Bakgrund: Under de senaste decennierna har behovet gällande effektivare logistikhantering inom alla branscher ökat. Detta härstammar bland annat från förändrade ekonomiska förutsättningar, geopolitiska omvälvningar och utvidgade globala försörjningskedjor. Den interna logistiken har en central roll för att effektivisera interna logistikaktiviteter som till stor del avser ett företags lager, färdigvarulager och godshantering. En bidragande faktor som avgör svårighetsgraden för dessa aktiviteter är produktens fysiska utformning, då tyngre och större föremål kräver mer resurser, såsom planering och hantering. Dock med dagens föränderliga marknad och dess tillhörande osäkerhet, blir påfrestningarna för företag och deras logistik- och lagerplanering mer påtagliga. Syftet: Syftet med denna studie är att undersöka hanteringen av tungt och otympligt gods i färdigvarulagret för att tidseffektivisera lageraktiviteterna som påverkar utlastningskapaciteten. Metod: Det har utförts en fallstudie på ett företag beläget i Gävle kommun, som i denna studie kallas för Företag X. För att kunna undersöka kring det valda ämnet har även ett till företag varit aktuell till denna fallstudie, även det företaget är beläget i Gävle kommun och kallas i denna studie för Företag Y. Genom observationer på Företag Y, intervjuer med personal från Företag Y, samt skriftlig och fysisk kontakt med personal på Företag X har empiriska data samlats in. En kvalitativ deduktiv ansats har använts för att besvara studiens syfte och frågeställning. Empiri: Från produktionen på Företag X till utlastningen på Företag Y är det många medverkande aktörer som alla har en påverkan på utlastningskapaciteten. Det sker även tre olika betydande aktiviteter innan kund får sina produkter, dessa är inlagring, preppning och direktlast/förlast. I dagsläget är det avtalat att Företag Y ska hantera utlastningen av 13 lastbilar per dag åt Företag X. Dock finns det en ojämn spridning kring antalet lastbilar som ankommer per dag samt deras ankomsttider. Slutsats: Studien påvisar att lageraktiviteterna som påverkar utlastningskapaciteten kunna tidseffektiviseras om slottidsbokningssystem, ett mer utvecklat lagerhanteringssystem samt rutiner kring inlagringen infördes, även att all tillgänglig resurs utnyttjades. / Background: In recent decades, more efficient logistics management has been increasingly required in all industries. This comes from, among other things, changed economic conditions, geopolitical upheavals and extended global supply chains. Internal logistics has a central role when the internal logistics activities are going to get more effective. Those internal logistics activities are mainly about a company's warehouse, finished goods warehouse and goods handling. A contributing factor that determines the degree of difficulty of these activities is the physical design of the product, as heavier and larger objects require more resources, such as planning and handling. However, with today's changing market and its associated uncertainty, the stresses on companies and their logistics and inventory planning are becoming more apparent. Purpose: The purpose of this study is to investigate the handling of heavy and unwieldy goods in the finished goods warehouse in order to make the warehouse activities that affect the loading capacity time-efficient.  Method: During this study we have implemented a case study on a company located in Gävle, that is referred to in this study as Company X. In order to investigate the chosen topic, another company has also been relevant to this case study, that company is also located in Gävle and is referred to in this study as Company Y. Through observations at Company Y, interviews with personnel from Company Y, as well as written and physical contact with personnel at Company X, the empirical data has been collected. A qualitative deductive approach has been used to answer the purpose and question of the study. Empiricism: From the production at Company X to the utilization at Company Y there are many participating actors who all have an impact on the loading capacity. There are also three different significant activities before the customer receives their products, which is storage, prepping and directloading/preloading. Currently is has been agreed that Company Y will handle the loading of 13 trucks per day for Comapny X. However, there is an uneven spread regarding the number of trucks that arrive per day and their arrival times.  Conclusion: The study shows that the warehouse activities that affect the loading capacity can be time-efficient if a slot time booking system, a more developed warehouse management system and routines regarding the storage were introduced, also that all available resources were utilized.
